SLIDING DOOR &
DOOR REPAIRS IN
CANBERRA.
Sliding doors off their track, doors that stick, locks that won’t catch. We fix the doors you use every day, across Canberra and Queanbeyan. Fixed price, quoted before we start.
A door that sticks in the frame, a sliding door that takes two hands and a shove, a lock that will not line up since the weather turned. These are the jobs that get put off for months because they do not feel urgent, until the day the door will not close at all. Polytechnitis handles residential door repairs across Canberra and Queanbeyan: the everyday timber, aluminium, and glass doors people actually use, not garage doors and not commercial automatic doors.
If the door is not working the way it should, it gets fixed. If it genuinely needs replacing, we will tell you that too, before you spend money on a repair that will not hold.
Sliding door repairs
Polytechnitis sees sliding doors fail in 3 predictable ways. The rollers wear flat, the bottom track fills with grit and corrodes, and the door drops on its frame and starts grinding. We fix all 3 mechanically in most cases, without replacing the door.
- Worn or seized roller replacement on glass and aluminium sliding doors
- Bottom and top track cleaning, repair, and capping replacement
- Realigning and re-hanging doors that have dropped or jumped the track
- Stiff or jammed sliding doors brought back to a one-finger glide
- Sliding screen and security door rollers, mesh, and latches
- Patio and stacker door adjustment
Aluminium and glass sliding doors are the most common call. If the glass itself is cracked or shattered, that is a glazier’s job and we will point you to one. The track, the rollers, and the alignment are ours.
Why sliding doors come off their track
Polytechnitis finds the same 3 causes behind almost every sliding door that jumps its track: the rollers have worn down, the bottom track is damaged, or the door has dropped out of square. Putting the door back without fixing the cause means it comes off again, usually within weeks.
Worn rollers, the most common cause
Polytechnitis puts worn rollers behind most Canberra callouts, and 3 signs separate them from a dirty track. The door grinds even after the track is cleaned. It sags lower on 1 side. It jumps off at the same spot every time. Sliding door wheels are small, and they carry a heavy panel for years. As they wear flat or the bearings seize, the door drops in the frame and starts riding on the lip of the track instead of rolling along it.
The quickest test takes 1 day. If a squirt of lubricant buys you a quiet door that goes back to grinding by tomorrow, the rollers are worn. Lubricant makes a worn roller quieter, it does not make it round again.
A damaged or clogged bottom track
Polytechnitis checks the track second, and the tell is a door that catches at 1 point along its run instead of dragging the whole way. Canberra’s dry summers push grit into the channel, and the leaf litter and frost that follow do the rest. Grit acts like a file on the track and the wheels together. Where the track lip has been stepped on or knocked it bends, and the door binds at that exact spot on every pass.
The door has dropped out of square
Polytechnitis measures the gap at the top and bottom of the door before touching anything, because a door out of square needs realigning rather than new wheels. Houses move, and Canberra’s clay soils and temperature swings move them more than most. Once the frame is out of square the door no longer sits parallel to the track, so it wears 1 roller far faster than the other and scrapes at the bottom corner.
What sliding door repair costs in Canberra
A sliding door repair in Canberra typically costs between $100 and $350, depending on whether it is a roller swap, a track repair, or both. Polytechnitis quotes a fixed price before any work starts, and there is no call-out fee, so the number you are told is the number on the invoice.
The published figures disagree with each other, and it is worth knowing why before you compare quotes. They are measuring different things.
| Source | What it measures | Published figure |
|---|---|---|
| Airtasker, Canberra | Average of completed Canberra sliding door tasks | $100 to $150, median $111 |
| What’s The Damage, Canberra | Doors, handles and hinges, low / typical / high | $110 / $175 / $310 |
| Slide Easy, sliding door specialist | Alignment through to full roller and track replacement | $150 to $350 |
Airtasker’s Canberra number is the lowest of the three because it is a bidding marketplace, not a rate card. Homeowners post a budget and taskers bid against it, so the average is pulled down by the simplest jobs. Its own list of completed Canberra jobs runs from $35 to put a wardrobe door back on its track in Kingston, up to $250 for a cavity slider in Narrabundah. One automatic door in the city centre came in at $800, and that is specialist work Polytechnitis does not take on. The spread is the honest answer here: the job name tells you almost nothing about the price, and the fault tells you everything.
That is why Polytechnitis quotes every door repair individually. Where your door lands depends on the project and its scope, so send photos of the door and the track and we will come back with a fixed price before anything is booked in. For what other handyman work costs around Canberra, our handyman prices in Canberra page sets out the market data job by job.
Repair or replace, with the numbers
Repairing a sliding door costs roughly a tenth of replacing it, so Polytechnitis repairs first in almost every case. A repair sits between $100 and $350. Supplying and installing a new external sliding door in Australia typically costs $1,500 to $3,500, and the installation labour alone runs $400 to $800, which is more than most repairs cost from start to finish.
Replacement genuinely wins in 4 cases. The timber frame is rotted through, the door is delaminating, the glass unit has failed and fogged, or the track is so far gone that no capping will hold it. In those cases we say so plainly, because a repair on a door that is past saving is money you spend twice.
Everything short of that is worth repairing. A properly adjusted door with new rollers runs like a new one and lasts years. Our guide to door problems fixed without replacing the door walks through the faults people assume are terminal and usually are not. Describe the problem when you call, or send a photo, and Polytechnitis will tell you straight which way the numbers point. We are not going to talk you into a replacement you do not need.
Cavity sliders and pocket doors
Polytechnitis repairs cavity sliders and pocket doors, the ones that disappear into the wall when they open, and 4 faults cover most of the callouts. They are the hardest sliding doors to diagnose because the roller carriage sits inside the wall cavity where you cannot see it, which is why a lot of them get left broken for years.
- Worn or broken roller carriages on cavity and pocket doors
- Doors that scrape the floor or jam partway into the cavity
- Head track adjustment and guide replacement
- Flush pulls, edge pulls, and privacy latches
We start with what can be reached through the jamb and the head track, and most faults are fixed from there without opening up the wall. Where the lining genuinely has to come off, we tell you before we start rather than halfway through. The plaster repair afterwards sits under our painting and wall repairs service, so it stays 1 team and 1 invoice instead of 2 trades.
Heavy sliders and stacker doors
Polytechnitis runs a team rather than a single van, which matters more on doors than on most jobs. A large glass slider or a stacker panel is not a safe one-person lift, and lifting one solo is how frames get scratched, glass gets chipped, and backs get hurt. Operators working alone often decline these doors for exactly that reason.
Because we can put more than one person on site, a door that needs 2 people to come out of its track safely is not automatically a no. Tell us the panel size and roughly how heavy the door feels when you enquire, and we will confirm what we can take on before anything gets booked. Where a door is genuinely beyond a handyman lift, we say so instead of turning up and finding out.
Hinged door repairs
Polytechnitis eases, planes, and re-hangs hinged doors across Canberra, and most of the time it is an adjustment rather than a new door. Timber moves with the seasons here: cold winters and dry summers swell and shrink the frame, so a door that closed fine in March can bind by July.
- Sticking and dragging doors eased, planed, and re-hung
- Sagging doors lifted, with hinges reset or replaced
- Internal, external, and laundry doors realigned
- Hollow-core and solid timber door repairs
- Door frames, stops, and weather seals adjusted
- New internal doors hung and trimmed to the opening
Locks, handles, and hardware
A door is only doing its job if it latches and locks, so Polytechnitis fits and repairs the 4 groups of door hardware below.
- Deadbolts, entrance sets, and privacy locks supplied and fitted
- Handles, latches, and strike plates replaced or realigned
- Screen and security door closers and locks
- Sliding door locks and pulls
For a straight lock swap or a new deadbolt after moving in, Polytechnitis is sorted. For restricted key systems, master-keyed commercial setups, or safe work, a licensed locksmith is the right call, and we will tell you so rather than guess.
What we don’t do
5 door jobs sit outside what Polytechnitis takes on, and they are listed below rather than buried in the fine print. Page one of Google for door repair in Canberra is mostly garage door companies and glaziers. We are neither, so it is worth being clear about where our work stops.
- Garage doors and garage door motors (a garage door specialist is the right call)
- Automatic or commercial sliding door systems
- Glass replacement in a broken sliding, French, or shopfront door (that is a glazier)
- Structural changes to load-bearing openings
- Restricted or master-key locksmithing
One visit, multiple jobs done
Most people who call Polytechnitis about a door have 3 or 4 other jobs waiting. While we are there for the sliding door, we can take care of the small jobs that have been sitting around: a shelf to hang, a fence gate that drags, a tap that drips. 1 visit, 1 invoice.
It is the same reason landlords and property managers book us for pre- and post-tenancy maintenance: doors, locks, and the dozen small things an exit report flags, all handled in a single visit. If your job needs more involved timber work, our carpentry and repairs service covers the rest. We repair doors in every suburb on our locations we service page, our home district is handyman Woden Valley, and we cross the border for handyman Queanbeyan jobs as well.
Fixed price. Quoted before we start. What you are quoted is what you pay.

Common questions
How do you fix a sliding door that won’t slide?
Polytechnitis fixes a stuck sliding door mechanically in 9 cases out of 10, because it is the rollers or the track. The rollers underneath wear flat or seize, and the bottom track fills with grit and corrodes, so the door drags instead of glides. We lift the door out, replace the worn rollers, clean or repair the track, then re-hang and adjust it so it runs with one finger. If the door has dropped on its frame, we realign it at the same time.
How much does sliding door repair cost in Canberra?
Published Canberra figures put a sliding door repair between $100 and $350, and Polytechnitis quotes every repair individually, with a fixed price before any work starts. Where a job lands depends on the project and its scope. A roller swap is a different job to a full track repair or a security door rebuild, so send photos of the door and the track with your address and we will come back with a real number. There is no call-out fee.
Is it cheaper to repair or replace a sliding door?
Repairing is cheaper by roughly 10 to 1. A sliding door repair in Canberra runs $100 to $350 in most cases, while supplying and installing a new external sliding door in Australia typically costs $1,500 to $3,500. The labour alone on a replacement is $400 to $800, which is more than most repairs cost in total. Polytechnitis only recommends replacement when the frame is rotted, the door is delaminated, or the glass unit itself has failed.
Why does my sliding door keep coming off its track?
A door that repeatedly jumps its track has usually lost roller height. As the wheels wear flat the door sits lower, so it rides on the lip of the track instead of rolling in it, and any small knock lifts it out. The other common cause is a bent or corroded bottom track. Polytechnitis checks both, because putting the door back without fixing the cause means it will come off again within weeks.
My sliding door won’t lock. How fast can you fix it?
Ring 0424 705 056 rather than filling in the form, because a door that will not lock is a security problem and it is quicker to talk it through. We call back the same day. Most sliding doors that will not lock do not have a broken lock. The panel has dropped on worn rollers or drifted out of line, so the latch no longer meets the keeper on the frame, and that is a roller and alignment fix. Standard rollers are on the van, so that is usually done in the one visit. If the lock itself has failed and a matching part has to be ordered, it becomes a second visit. Until then, a length of timber dowel or a cut-down broom handle laid in the bottom track stops the door being slid open from outside.
Do you repair cavity sliders and pocket doors?
Yes. Cavity sliders and pocket doors, the ones that disappear into the wall, are within scope for Polytechnitis. They are the hardest sliding doors to diagnose because the roller mechanism sits inside the wall, so we start by checking what can be reached through the jamb and the head track. Most faults are worn roller carriages or a door that has dropped and is scraping the floor, and most can be fixed without opening up the wall. If yours does need the lining opened, we will tell you before we start, not halfway through.
Do you repair the glass in a sliding door?
No. Cracked or shattered glass is a glazier’s job, and Polytechnitis will point you to one. What we handle is the mechanical side: the rollers, the track, the alignment, the locks, and the screen. If the glass is fine but the door will not move, that is exactly our work.
Do you fix garage doors?
No. Garage doors and garage door motors need a garage door specialist with the right parts and springs, and Polytechnitis does not take them on. Page one of Google for door repair in Canberra is full of those companies. We are the handyman you call for the front door, the back slider, and the internal doors, not the roller door on the garage.
Can you fix a door that sticks after winter?
Yes, and it is one of the most common calls Polytechnitis gets. Canberra’s cold winters and dry summers swell and shrink timber doors and frames, so a door that closed fine in autumn binds by mid-winter. We ease, plane, and re-hang the door, reset the hinges if needed, and adjust the frame so it closes cleanly through the seasons.
Do you repair screen and security doors?
Yes. Sliding screen and security door rollers, mesh, latches, and closers are all within scope for Polytechnitis. If the screen door has jumped its track or the closer has given out, we sort it. For restricted or master-key locking systems, a licensed locksmith is the right call, and we will say so.
My sliding door is too heavy for one person. Can you still repair it?
Yes. A large glass slider or a stacker panel is not a safe one-person lift, which is why some operators decline them. Polytechnitis runs a team rather than a single van, so a door that needs 2 people on site to lift it out safely is not automatically a no. Tell us the panel size when you enquire and we will confirm before booking.
Can I replace sliding door rollers myself?
On a light screen door, often yes. On a glass slider, think twice. Rollers are not universal: they vary by brand, panel weight and track profile, and the wrong one wears out fast or will not sit in the track properly. The panel also has to come out of its track, and a large glass slider or stacker panel is not a safe one-person lift. That is how glass gets chipped, frames get scratched and backs get hurt. If you do take it on, have a second person there, pad the spot where the panel will rest, and take the old roller with you when you buy the new one. Otherwise send us photos of the door and the track and we will quote a fixed price.
