Question 1

How much does a new garage door cost in Australia?

Accepted Answer

A new garage door in Australia typically costs between $1,200 and $5,500 fully installed, depending on size, material, and style. A standard Colorbond steel sectional door runs $1,500–$2,500, while a double sectional is usually $2,500–$3,800. Roller doors are the most budget-friendly at $1,200–$2,000 for a single. Premium options like solid timber or custom-designed doors can exceed $7,000. Adding an automatic opener generally costs an extra $500–$900 installed. Prices vary by region — metro Sydney and Melbourne often run higher than regional areas. Always get at least three quotes from local installers, and check whether removal of the old door, motor wiring, weatherseals, and warranty are included in the price.

Question 2

How long does a garage door last?

Accepted Answer

A well-maintained garage door in Australia generally lasts 20–30 years, while the opener motor typically needs replacing every 10–15 years. Colorbond steel sectional and roller doors are the workhorses of Aussie homes and routinely last 25 years or more with basic care. Timber doors need more upkeep and often require refurbishment after 15 years, particularly in coastal regions where salt air accelerates wear. Springs — torsion or extension — usually last 7–12 years, or roughly 10,000 open-close cycles. If your door opens four or more times a day, expect to replace springs sooner. Annual servicing extends life dramatically by catching worn rollers, frayed cables, and loose hardware early.

Question 3

Why won't my garage door open?

Accepted Answer

The most common reasons a garage door won't open are a flat remote battery, a tripped circuit breaker, broken springs, or the motor's lock-out / holiday mode being enabled. Start by replacing the remote battery and trying the wall button. If the wall button works but the remote doesn't, it's a remote or receiver issue. If neither works, check the powerpoint and breaker. A loud bang followed by a door that won't lift usually means a snapped torsion spring — the motor can't lift the door's weight without the spring counterbalancing it. Other causes include misaligned safety sensors (look for a blinking LED), a disengaged trolley, or worn drive gears. Don't force the door — call a technician if springs are involved.

Question 4

Why won't my garage door close?

Accepted Answer

Nine times out of ten, a garage door that opens but won't close has dirty, blocked, or misaligned safety photo-eye sensors near the floor. Check for cobwebs, leaves, or stored items breaking the beam, and confirm both LEDs glow steadily. Bumped sensors can knock alignment out — gently rotate them until both lights are solid. Other causes include a close-limit setting that needs adjustment, a damaged track, or worn rollers binding the door. If the door starts to close then reverses, the auto-reverse force may be set too sensitive, or there's a real obstruction like a buckled panel or broken cable. Test by holding the wall button down — if it closes that way, the sensors are the issue.

Question 5

What is the most common garage door problem?

Accepted Answer

By a wide margin, the most common garage door problem is broken torsion or extension springs. Springs absorb almost all of the door's weight and cycle every time you open or close — they're consumables with a finite life of around 10,000 cycles. The second most common issue is misaligned or dirty safety sensors, which prevent the door from closing. Worn rollers and hinges (causing noisy operation), frayed cables, remote battery failures, and motor gear strip-out round out the top five. Most of these are preventable with a yearly service that includes lubrication, hardware tightening, balance testing, and a safety check. Annual servicing is much cheaper than emergency repairs.

Question 6

How often should I service my garage door?

Accepted Answer

You should service your garage door once a year, or every six months if you open it more than four times a day. A professional service costs $120–$220 in Australia and includes lubricating rollers, hinges, springs and tracks; tightening hardware; checking spring tension and door balance; testing auto-reverse safety; inspecting cables and drums; and adjusting the opener's force and travel limits. Between services you can do a few things yourself — listen for new noises, wipe tracks clean, and lubricate moving parts with a silicone-based or lithium spray (never WD-40, which strips lubrication). Coastal homes should service every six months due to salt corrosion, and rural homes more often if dust or insects are an issue.

Question 7

Can I replace garage door springs myself?

Accepted Answer

You should not replace garage door springs yourself. Torsion springs hold enormous stored energy — a single spring can exert hundreds of kilograms of force when released, and DIY replacements are responsible for serious injuries every year in Australia, including broken bones, lost fingers, and worse. The job requires winding bars, the correct spring rating for your door's weight, and an understanding of how to safely tension the spring without it slipping. A licensed technician will replace a single torsion spring for $250–$450 including labour and a quality spring, usually in under an hour. Extension springs are slightly less dangerous but still risky. Spend the money — it's not worth the hospital visit.

Question 8

How much does it cost to replace garage door springs?

Accepted Answer

Replacing a garage door spring in Australia costs $250–$450 for a single torsion spring fully fitted, or $400–$700 if both springs need replacing (recommended, since they wear at the same rate). Extension springs are slightly cheaper at $180–$350 per pair. The price includes the spring itself, callout, and labour, and most jobs are done in 60–90 minutes. Heavier or oversized doors with larger-gauge springs cost more — sometimes $500–$800 a side for double doors with timber panels or insulated steel. Always replace springs in pairs even if only one has snapped; a mismatched pair causes the door to lift unevenly and shortens the life of the new spring.

Question 9

What's the difference between torsion and extension springs?

Accepted Answer

Torsion springs sit horizontally above the door on a metal shaft and twist (torsion) to lift the door. They're more durable, balance the door more smoothly, and are now the industry standard on most modern Australian sectional and roller doors. Extension springs run vertically along the horizontal tracks on either side and stretch (extend) to provide lift. They're cheaper but wear faster, are noisier, and can fly across the garage if they snap without a safety cable. Torsion systems last longer (15,000–20,000 cycles vs 10,000 for extension), are quieter, and offer better balance — which is why nearly every new sectional door in Australia ships with torsion springs.

Question 10

Why is my garage door making a loud noise?

Accepted Answer

A loud or grinding garage door usually means worn metal rollers, dry hinges and tracks, loose hardware vibrating against the frame, or worn opener gears. Plastic or nylon rollers run almost silently — if yours are noisy steel rollers, swap them out for around $10–$15 each. Rattling typically means loose bolts; go around with a spanner and tighten everything. A grinding sound from the opener motor often signals a stripped main drive gear, a $40 part but $180–$280 with labour. A loud bang during operation can indicate a snapped spring or cable — stop using the door immediately and call a technician. Annual lubrication of rollers, hinges, and springs prevents most noise issues.

Question 11

Why does my garage door reverse before fully closing?

Accepted Answer

A door that reverses before closing has either a real obstruction or a setting problem. First, check the bottom seal and floor for stored items, leaves, or debris. Then look at the safety sensors — even a slight misalignment makes the opener reverse for safety. If the area is clear and sensors are aligned, the close-force or close-limit on the opener may be set incorrectly. Most modern openers have dial or button adjustments to fine-tune force sensitivity and travel distance — consult the manual, or have a technician calibrate it. Worn rollers or a bent track can also cause increased friction the opener interprets as an obstruction. Don't override the safety system; it exists to prevent crushing accidents.

Question 12

How do I program my garage door remote?

Accepted Answer

Programming a new garage door remote takes about 30 seconds on most Australian openers (B&D, Merlin, Centurion, ATA). Locate the Learn or Code Set button on the motor head — usually under a small cover on the back or side. Press and release it; an LED will flash or stay solid for around 30 seconds. While the LED is active, press the button on your new remote you want to assign. The light will flash to confirm pairing. Test by pressing the remote — the door should respond. If it doesn't pair, check the remote's battery and confirm it's the correct frequency for your motor (most older B&D units are 27MHz; newer ones are 433MHz). Always erase old remotes if you sell your home.

Question 13

My garage door remote isn't working — what should I do?

Accepted Answer

Start with the simplest fix: replace the battery. Most garage remotes use a CR2032, 23A, or 9V battery, and a flat one is the cause about 70% of the time. If a new battery doesn't help, try the remote within a metre of the motor — if it works up close but not from the driveway, you have signal interference. If still nothing, try a second remote if you have one — that confirms whether the issue is the remote or the receiver in the motor head. Reprogramming the remote often fixes intermittent faults. Older remotes may simply have failed and need replacing — universal remotes are around $40–$80.

Question 14

What's the best garage door opener brand in Australia?

Accepted Answer

The leading garage door opener brands in Australia are Merlin, B&D, ATA, Centurion, and Chamberlain — all reliable, widely supported, and with good local parts availability. Merlin (made by Chamberlain) and B&D dominate the residential market and offer smartphone-compatible models like the Merlin MyQ and B&D Smart Phantom. ATA is excellent value and used by many builders. For premium quiet operation, Centurion's belt-drive motors are hard to beat. Look for openers with battery backup (essential during blackouts), soft start/stop, and at least a 5-year motor warranty. Avoid no-name imports — parts are hard to source. Expect to pay $500–$900 supplied and installed for a quality residential opener.

Question 15

How long does a garage door opener last?

Accepted Answer

A residential garage door opener typically lasts 10–15 years in Australia. Belt-drive openers tend to outlast chain-drive units because they put less stress on the motor and need less maintenance. Heavily-used doors (a busy household opening 6–8 times a day) may wear out an opener in 8–10 years, while a holiday home unit can easily last 20+ years. Common failure points are the main drive gear (often plastic, repairable for $150–$250), the logic board (replaceable for $200–$350), or the motor itself. If yours is over 12 years old, lacks rolling-code security, or doesn't have safety sensors, replacing the entire unit is usually smarter than chasing repairs — and you'll get smartphone control as a bonus.

Question 16

Are sectional or roller doors better?

Accepted Answer

Both have their place. Sectional doors (panel doors that lift up and overhead) offer better insulation, look more upmarket, seal more tightly against weather, and are quieter when fitted with torsion springs and a belt-drive opener — making them the popular choice for attached garages. Roller doors (a single curtain that rolls into a drum above the opening) are cheaper, take up less ceiling space, and let you park closer to the door — making them ideal for shallow garages or carports. Sectionals cost $1,500–$3,800 installed; rollers $1,200–$2,000. For a modern home where the garage faces the street, a Colorbond sectional with woodgrain panels is hard to beat aesthetically.

Question 17

Tilt door vs sectional door — what's better?

Accepted Answer

Sectional doors have largely replaced tilt (single-panel up-and-over) doors in Australia, and for good reason. Tilt doors swing outward as they open, requiring a metre of clear space in front of the garage — a problem on short driveways. They also don't seal well, are heavier, and put more stress on motors. Sectional doors lift straight up and tuck horizontally along the ceiling, allowing you to park right up against them. Sectionals offer better insulation, better security, smoother operation, and a cleaner appearance. The only times a tilt door makes sense are heritage replacements where the original look needs to be matched, or budget-only situations on a workshop or carport.

Question 18

What size garage door do I need?

Accepted Answer

Standard Australian garage door sizes are 2400mm high × 2400mm wide for a single, and 2400mm × 4800mm for a double — but always measure your opening rather than assuming. Take three width measurements (top, middle, bottom) and three height measurements (left, centre, right) to check the opening is square. You also need to measure side room (at least 90mm each side for tracks), headroom (300–450mm above the opening for the tracks and spring shaft), and backroom (the door's height plus 600mm). Modern SUVs and 4WDs often need 2700mm-high doors to clear roof racks and bike carriers. Roller doors need less headroom (around 300mm) than sectionals.

Question 19

Can I insulate my existing garage door?

Accepted Answer

Yes — DIY garage door insulation kits cost $80–$200 and take an afternoon. The most common option is foil-backed polystyrene panels cut to fit each section of a sectional door, held in with adhesive or clips. Reflective foil bubble wrap is a cheaper alternative, especially good for reflecting summer heat in northern Australia. Don't insulate a roller door — the curtain has to roll into a small drum and added thickness will jam it. The catch with retrofit insulation is that it adds weight, which can throw off the door's balance and shorten spring life — have a technician re-tension after fitting. For best results, a factory-insulated sectional door outperforms anything you can retrofit.

Question 20

Do garage doors come with insulation?

Accepted Answer

Most standard Australian garage doors are not insulated — the entry-level Colorbond sectionals and roller doors are single-skin steel. Insulated sectional doors are available from all major brands (B&D, Steel-Line, Gliderol, Taurean, Dominator) and use foam-injected panels with R-values typically between R2.0 and R4.7. They cost around 30–50% more than standard doors but make a noticeable difference for attached garages, garages with rooms above, and homes in Melbourne, Canberra, and Tassie where winter cold is a factor. Insulated doors are also stiffer, more dent-resistant, quieter in operation, and have a softer feel inside. If your garage is heated, cooled, or used as a workshop or gym, an insulated door pays back quickly.

Question 21

What's the best material for a garage door?

Accepted Answer

For most Australian homes, Colorbond steel is the best garage door material — it's durable, corrosion-resistant, available in 22 standard colours, low-maintenance, and reasonably priced. Aluminium is lighter and rust-proof, ideal for coastal homes within 1km of the surf. Timber (cedar, mountain ash, merbau) looks stunning on premium homes but needs re-oiling every 1–2 years and is the most expensive option at $4,000–$10,000+. Composite or aluminium-framed doors with timber-look inserts give the warmth of timber without the upkeep. Glass-panel sectional doors are increasingly popular for architectural homes. For sheds and workshops, plain Zincalume or factory-painted steel roller doors are the budget pick. Match material to your climate, style, and maintenance appetite.

Question 22

Are Colorbond garage doors worth it?

Accepted Answer

Yes — Colorbond garage doors are excellent value and the most popular choice in Australia for good reason. The pre-painted steel resists fading, chalking, peeling, and corrosion far longer than generic painted steel, and BlueScope backs it with warranties up to 25 years (depending on the colour and environment). Coastal homes within 1km of breaking surf should choose Colorbond Stainless or Colorbond Ultra for added salt resistance. Colorbond doors come in matched roof, wall, and trim colours, so coordinating your home's exterior is easy. Expect to pay $1,500–$3,800 for a single sectional installed. The main downsides are visible dents from knocks, and that thin single-skin doors can be noisy in heavy rain.

Question 23

Are timber garage doors a good choice in Australia?

Accepted Answer

Timber garage doors look spectacular and add real street appeal — particularly cedar, merbau, or spotted gum on a federation or contemporary home — but they demand commitment. Australian sun is brutal on timber, and a north or west-facing timber door needs re-oiling or recoating every 12–24 months to prevent splitting, fading, and warping. Costs range from $4,000 for a basic cedar overlay on a steel door up to $12,000+ for solid timber custom builds. Timber-look composite doors (aluminium frame with woodgrain Decotech, Axon, or vinyl-wrap panels) deliver 90% of the look with 10% of the maintenance, for around $3,500–$5,500.

Question 24

How do I clean my garage door?

Accepted Answer

Clean your garage door at least twice a year — more often near the coast or in dusty rural areas. Hose it down to remove loose dirt, then wash with warm water and a mild dishwashing detergent using a soft sponge or car-washing brush. Avoid high-pressure washers (they can drive water into electronics and dent thin steel) and never use abrasive pads, solvents, or harsh cleaners on Colorbond — these strip the protective coating. Rinse thoroughly to prevent detergent residue. For timber doors, use a timber-specific cleaner and re-apply oil if the surface looks dry. Don't forget to clean the bottom rubber seal and tracks.

Question 25

Why is my garage door rusting?

Accepted Answer

Surface rust on a steel garage door usually means the protective paint layer has been scratched or worn through, exposing the steel underneath. Coastal salt air accelerates this dramatically, particularly within 1km of the surf. Small spots can be sanded back, treated with a rust converter (like Ranex or Penetrol), primed, and touched up with a colour-matched paint — Colorbond touch-up kits are available from Bunnings for $20–$30. Rust at the bottom edge often comes from the door sitting in puddles; check the floor seal and slope. If rust has perforated the panel or is widespread, replacement is more economical than refurbishment.

Question 26

Can I paint my garage door?

Accepted Answer

Yes, you can repaint a steel garage door — and a fresh coat can transform a tired-looking facade for a few hundred dollars. Wash the door thoroughly with sugar soap and rinse, lightly sand to provide a key, treat any rust spots with a converter, and apply two coats of an exterior acrylic or specialised metal paint (Dulux Weathershield, Solver Garage Door Paint, or Taubmans All Weather). Use a small roller for flat panels and a brush for crevices. Choose a mild-weather day under 25°C for best results. Avoid painting Colorbond unless you're prepared to repeat every few years.

Question 27

How much does it cost to install a garage door?

Accepted Answer

Garage door installation in Australia, including the door, hardware, and labour, typically costs $1,200–$5,500 for a single door and $2,500–$6,500 for a double. Standard installation (4–6 hours) involves removing the old door, fitting tracks and springs, hanging the new door, installing weatherseals, and commissioning the opener. Add $500–$900 if you also need a new automatic opener. Tricky installations — high ceilings, unusual openings, removal of asbestos lintels, or steel reinforcing — can add $200–$600. Get itemised quotes that include rubbish removal, GST, warranty terms (look for at least 5 years on the door and 5 on the motor), and confirmation that the installer is appropriately licensed and insured.

Question 28

Can I install a garage door myself?

Accepted Answer

Technically yes, but very few homeowners should. Roller doors are the most DIY-friendly and a competent handyperson can install one in a day with two people. Sectional doors are far more complex — they involve winding torsion springs to several hundred kilograms of tension, which is genuinely dangerous without the right tools and experience. Even if you successfully install it, a poorly balanced door will burn out a motor and tear cables within months. DIY also voids most manufacturer warranties on the door and the opener, and many councils require licensed installation. The $300–$500 you save isn't worth the safety risk or the long-term reliability hit. Hire a pro for sectional doors.

Question 29

Do I need a permit to install a garage door?

Accepted Answer

For a like-for-like replacement of an existing garage door, you don't usually need a permit anywhere in Australia. If you're enlarging or moving the opening, building a new garage from scratch, or your home is heritage-listed or in a covenant-controlled estate, you'll likely need council approval, planning consent, or estate committee sign-off. Body corporate properties (units and townhouses) almost always require committee approval for any visible exterior change. Always check with your local council before quoting — rules vary between Sydney, Melbourne, Brisbane, and regional shires. A reputable installer will know the local requirements and can lodge paperwork on your behalf, often included in the quote.

Question 30

How do I open my garage door during a power outage?

Accepted Answer

Every automatic garage door has a manual release — usually a red cord with a handle dangling from the opener trolley. Pull it down (and slightly back toward the motor on some models) to disengage the trolley from the opener, then lift the door by hand. The door should glide smoothly if the springs are properly tensioned; if it feels heavy, get the springs serviced. To re-engage after the power returns, either pull the cord again or simply press the remote — the trolley will reconnect on the next cycle. If the door is locked from the inside, use the external emergency key release — keep the keys handy, not buried in a kitchen drawer.

Question 31

What is auto-reverse safety, and how do I test it?

Accepted Answer

Auto-reverse is a federally mandated safety feature on every modern garage door opener that detects an obstruction and reverses the door to prevent crushing injuries — vital in homes with children and pets. There are two systems: photoelectric sensors (the small eyes 150mm above the floor that send an infrared beam across the opening), and force-sensing (the motor reverses if it meets resistance). Test both monthly. Place a 50mm-thick block of wood flat on the floor in the door's path; the door should reverse on contact. For sensors, wave a broom across the beam as the door closes — it should reverse instantly. If either fails, stop using the opener and call a technician.

Question 32

Why does my garage door open by itself?

Accepted Answer

A garage door opening on its own is unsettling but almost always has a benign cause. The top three are: a stuck button on the wall control or remote (caused by jammed dirt or a swollen battery), a remote in another car or your pocket being pressed accidentally, or radio frequency interference from a neighbour's opener on the same code (rare on modern rolling-code units but common on old fixed-code remotes pre-2005). Less commonly, a wet or damaged wall-button wire causes intermittent shorts that trigger the motor. Solutions: clean or replace the wall button, upgrade old remotes to a rolling-code system, and check wiring for damage. If it persists, replace the opener — old units aren't worth chasing.

Question 33

Can someone hack my garage door opener?

Accepted Answer

Older garage door openers using fixed-code remotes (pre-2005, mostly 27MHz) can absolutely be hacked — a $30 code grabber from overseas can capture the signal and replay it. Modern openers with rolling-code or AES-encrypted signals (Merlin Security+, B&D TriTran+, Chamberlain Security+ 2.0) use a different code every time you press the button and are effectively un-cloneable with consumer tools. If your opener is over 20 years old, upgrade it. Smartphone-controlled openers (MyQ, Phantom) add another layer but can be vulnerable if your home Wi-Fi is poorly secured — use a strong password and keep the firmware updated. The simplest extra protection is locking your car, since most garage break-ins start with stealing the car remote.

Question 34

What is a smart garage door opener and is it worth it?

Accepted Answer

A smart garage door opener connects to your home Wi-Fi and lets you open, close, and monitor the door from a smartphone app, and often integrates with Google Home, Apple HomeKit, or Alexa. Popular Australian options include the Merlin MyQ, B&D Smart Phantom, and Chamberlain MyQ — all around $700–$950 installed, or $50–$200 as an add-on module to a compatible existing opener. The benefits are real: you can let in deliveries while you're at work, get a notification if the door is left open, set schedules, and check the door from holiday. Downsides are reliance on Wi-Fi (no internet = no remote control) and occasional subscription fees for some advanced features. For most modern households, smart openers are well worth it.

Question 35

How do I weatherseal or draft-proof my garage door?

Accepted Answer

Most garage door drafts come from the bottom seal, the side jambs, and the top header. Replace a worn bottom rubber seal — universal P-shape, T-shape, and bulb seals are available at Bunnings or specialist stores for $30–$80 and slide into the existing track in 10 minutes. Side and top seals (brush or rubber strips screwed to the door frame) keep wind and rain out and are inexpensive to add. For a sectional door, also check the inter-panel seals — these wear over time and let in dust. If the floor isn't level, an aluminium threshold seal glued to the concrete fills uneven gaps. Properly sealed, an attached garage stays significantly cooler in summer and warmer in winter.

Question 36

How much does an automatic gate cost in Australia?

Accepted Answer

A complete automatic gate installation in Australia generally costs $4,500–$15,000, depending on size, material, motor, and site complexity. A basic single-leaf swing gate with a Centurion or D-Series motor runs $4,500–$7,000 installed; a double-leaf swing gate is $6,500–$10,500. Sliding gates start around $5,500 for a 4-metre aluminium gate and reach $14,000+ for steel or wrought-iron 6-metre gates with high-end motors. Add $500–$1,500 for safety photocells, intercoms, and keypads; $300–$800 for solar power if no mains is available; and $200–$600 for trenching cable runs over long driveways.

Question 37

Sliding vs swinging gate — which is better?

Accepted Answer

Sliding gates work better on sloping driveways, narrow blocks where there's no room for a swing arc, and high-wind areas — they don't fight the wind the way a swing gate does. They need clear room beside the opening for the gate to slide into, plus a level track. Swinging gates suit flat blocks with plenty of front space and traditional aesthetics — they're also generally cheaper and have fewer mechanical parts to fail. Swing gates can open inward or outward and are available as single or double leaves. As a rough guide: long flat driveway with classic styling = swing; sloped, narrow, or windy site = sliding. Sliding gates have overtaken swing gates as the most-installed type in new Australian homes.

Question 38

How long does an automatic gate last?

Accepted Answer

A well-built automatic gate lasts 25–30 years for the gate itself and 10–15 years for the motor. Aluminium gates outlast steel in coastal areas because they don't rust. Stainless steel and powder-coated mild steel both last 20+ years inland but need re-coating every 8–12 years near the surf. Timber gates are the shortest-lived at 10–15 years before significant refurbishment. Motors typically wear out at the gearbox or main board; common Australian brands (Centurion, FAAC, Nice, BFT, Centsys) all offer parts and service for 15+ years post-purchase. Annual servicing — checking the track, lubricating hinges, testing safety sensors, and tightening hardware — significantly extends the life of both the gate and motor.

Question 39

What's the best automatic gate motor brand?

Accepted Answer

The most respected gate motor brands in Australia are Centurion (South African, very popular for sliding gates), FAAC (Italian, premium hydraulic and electromechanical), Nice (Italian, broad range), BFT (Italian, durable underground motors), and Centsys (the local distribution arm of Centurion). For domestic sliding gates, the Centurion D5-Evo and D-Series are the workhorses. For swing gates, the FAAC 412 (hydraulic) and Nice Wingo (electromechanical) are common. Choose a brand with strong local parts and service support — a cheap unknown motor can leave you stranded when it fails. Expect to pay $1,200–$3,000 for a quality motor supplied and installed, depending on type and gate weight. Always insist on a 2-year minimum warranty.

Question 40

Why won't my electric gate open?

Accepted Answer

The most common causes of an electric gate not opening are a flat remote battery, tripped safety photocells, a tripped safety edge, low battery on solar setups after cloudy weather, or a manual-release lever that's been disengaged and not re-engaged. Start with the basics: try a second remote or the keypad if you have one. Check for an LED on the receiver — solid usually means power is fine. Look for blocked photocells (cobwebs, leaves, parked car). Try the manual release key on the motor and see if the gate moves freely by hand — if it does, the issue is in the motor or controls; if not, the gate has a mechanical bind. Don't force a stuck gate; you'll damage the gearbox.

Question 41

Why won't my electric gate close?

Accepted Answer

A gate that opens but won't close almost always has a triggered safety device — a photocell beam blocked, a safety edge being squeezed, or an inductive loop sensing a vehicle still in the gateway. Clean the photocells, check both LEDs are solid, and confirm there's nothing across the gate's path including small children, pets, or low shrubs. If you have an exit loop buried in the driveway, a metal object on or above it may be holding the gate open. Other causes include the motor's auto-close timer being disabled or set very long, or a low battery on a solar-powered setup. If clearing safety devices doesn't help, the close-limit may need adjustment by a technician.

Question 42

How often should I service my automatic gate?

Accepted Answer

Service your automatic gate at least once a year. The cost in Australia is typically $180–$320 and includes lubricating the track and rollers (sliding) or hinges and pivots (swing), tightening hardware, checking and lubricating the motor's gearbox if accessible, testing safety photocells and edges, checking the manual release operation, and adjusting force and travel limits. Coastal homes should service every six months due to salt corrosion on tracks and hardware. Heavy-use gates (more than 15 cycles a day) also warrant six-monthly checks. Between services, brush leaves and dirt out of the sliding gate track weekly — debris in the track is the single biggest cause of premature roller wear and motor strain.

Question 43

Can I install an automatic gate myself?

Accepted Answer

You can install a non-automated gate yourself if you're handy, but full automatic gate installation is best left to a professional. The complexity comes from accurate post setting (concrete footings need to be plumb to within a few millimetres for the gate to swing or slide cleanly), correct cable runs to the motor and accessories, electrical compliance for mains-powered installs (which usually require a licensed electrician anyway), and programming the motor's force, travel limits, and safety devices. DIY kits exist and start around $1,800 for the motor and accessories, but warranties on most major brands are voided without certified installation. For sliding gates over 4 metres or any gate over 200kg, a professional install is strongly recommended.

Question 44

What power supply does an automatic gate need?

Accepted Answer

Most automatic gate motors run from a 24V DC battery inside the motor head, which is trickle-charged from either 240V mains or a solar panel. Mains is the gold standard — reliable, cheap, and able to handle high-cycle use. Running mains to the gate typically costs $300–$1,500 depending on distance, trenching, and whether a licensed electrician needs to run conduit from the meter box. Solar power is excellent for rural properties or where running mains is impractical: a 20–80W panel plus a sealed battery suits most home gates with up to 15–20 cycles a day. Solar adds $400–$900 to the installation. Overcast winter periods can drain solar batteries, so size the panel generously.

Question 45

What's the best gate material — aluminium, steel, or timber?

Accepted Answer

Aluminium is the most popular gate material in modern Australia — it doesn't rust, is light (easier on motors and bearings), comes powder-coated in any colour, and lasts 25+ years with almost no maintenance. Steel is heavier and stronger, ideal for security-focused installations and traditional wrought-iron looks, but needs galvanising and powder-coating to last in coastal areas. Timber gates look beautiful but require re-oiling every 1–2 years, can warp in extreme weather, and add weight that strains gate motors. For 80% of Australian homes, powder-coated aluminium with vertical battens or a horizontal-slat infill is the sweet spot of looks, durability, and value. For premium country estates, hot-dip galvanised steel is hard to beat.

Question 46

Do automatic gates work during a power outage?

Accepted Answer

Most modern automatic gates have a battery backup that gives 5–20 cycles during a blackout — enough to get in and out for a day or two. After the battery is exhausted (or if your motor doesn't have battery backup), every gate motor includes a manual release: a key-operated lever or knob on the motor that disengages the drive so you can push the gate by hand. The release is designed for emergencies, so know where it is and where the key is kept before a blackout happens. To re-engage, simply turn the lever back and the next remote press will recouple the drive. Solar-powered gates are unaffected by mains outages but may be limited by battery state in long overcast periods.

Question 47

Are automatic gates safe for pets and children?

Accepted Answer

Modern automatic gates are very safe when installed correctly — they're required to meet AS 4687 with multiple safety devices: photoelectric sensors (infrared beams that detect anything in the gate's path), safety edges (rubber strips on the gate that stop or reverse the gate when squeezed), force limiters in the motor, and manual release in case of failure. That said, never let children play near the gate, and never let pets out near a moving gate without supervision — small dogs especially can dart through faster than the safety system can react. Train family members to wait for the gate to fully open or close before walking through. Test safety devices monthly the same way you test garage door auto-reverse.

Question 48

How do I add a remote or intercom to my existing gate?

Accepted Answer

Most existing gate motors can be expanded with extra remotes, keypads, intercoms, and smartphone modules at modest cost. Spare remotes are $40–$100 and pair via a Learn button on the receiver — the procedure is in your manual and similar to garage door remotes. Keypads add $200–$400 supplied and let visitors enter a PIN. Audio intercoms are $400–$700; video intercoms with smartphone integration (Aiphone, Comelit, BFT) run $900–$1,800 installed. Wi-Fi modules from your motor's manufacturer (Centurion ChronoGuard, Nice MyNice, FAAC J-Fit) let you control and monitor the gate from a phone app for $250–$500. Compatibility depends on your motor's age and brand — check before buying.

Question 49

What's the difference between underground and articulated gate motors?

Accepted Answer

Both are types of swing-gate motor and the choice mainly comes down to looks and budget. Underground motors (also called below-ground or in-ground) sit in a sealed metal box buried in concrete at the gate's pivot point, with only a small lever visible — they're the cleanest, most architectural option, and ideal for premium homes. They cost more ($1,500–$3,500 a leaf installed) and require excavation and good drainage to avoid flooding. Articulated motors (also called arm or ram motors) sit on the gate post and connect to the gate via a jointed arm or straight ram. They're cheaper ($800–$2,000 a leaf installed), easier to retrofit, and easier to service — but more visible. For new builds aiming for a high-end look, choose underground; for retrofits, articulated.

Question 50

How do I stop my gate from sagging?

Accepted Answer

Sagging is most common on swing gates and is caused by a combination of gate weight, hinge wear, and post movement. The fix depends on the cause. If the post has tilted, you'll need to dig it out and reset it in deeper concrete (600–800mm deep is typical for a residential gate post). If the hinges are worn, replace them with heavy-duty marine-grade or roller-bearing hinges rated above your gate's weight. For long single-leaf gates, fitting an anti-sag wheel under the latch end takes the load off the hinges and is a $100–$250 retrofit. Adding a diagonal brace from the bottom hinge to the top of the latch side stiffens the gate frame itself. For a chronically sagging gate, an automatic gate with a wheel-supported sliding design is often the long-term answer.
