Garage Door Repair
Garage Door Repair near you
Garage doors in Britain rarely fail gracefully. A spring on an up-and-over door snaps with a bang and the door becomes too heavy to lift; a roller door's curtain jams halfway and will not go either way; a sectional door comes off its track after a cable lets go. Because so many British garages still have doors fitted decades ago, a large share of repair work is on gear that has simply worn out in damp air.

A garage door engineer replaces springs, cables and the cones and shafts they run on, frees and realigns tracks, changes rollers, hinges and bearings, rebalances doors, repairs or replaces corroded subframes and lintel fixings, and repairs powered operators and their safety devices. Springs hold a great deal of stored energy even when the door is closed, which is why spring and cable work belongs to a trained engineer rather than a weekend repair.
Damp is the British complication. Rain driven at a north-facing door, condensation inside an unheated garage and salt near the coast corrode springs, cables and the steel frame from the inside out, so a door that looks sound from the drive can be close to failure at the parts you cannot see. This page covers what goes wrong, what to do the moment something breaks, the checks you can safely make yourself, what a repair visit involves and when a repair stops being worth it.
Common garage door faults and what usually causes them
A garage door is a balanced system: the door, the frame it hangs in, the springs and cables that carry its weight, and on a powered door the operator and its safety devices. A symptom in one part very often starts somewhere else, which is why a competent engineer runs the door by hand before replacing anything.
- Suddenly very heavy: the classic sign of a broken spring on an up-and-over or sectional door, because without the spring you are lifting the full weight of the door.
- Door drops or slams shut: a failed or stretched spring, or a cable that has come off its drum, so the door is no longer counterbalanced.
- Jams part way: a bent track, a seized roller, a corroded pivot or debris in the track, and on a roller door a curtain that has come out of its side guides.
- Grinding and squealing: dry or worn rollers, bearings and pivots, often accelerated by damp in an unheated garage.
- Door sits crooked in the opening: one side is lifting before the other, usually an uneven cable or a worn pivot, and it will wear the tracks if left.
- Rust at the frame and the bottom edge: British damp attacks the subframe and the lowest part of the panel first, and a frame that has rusted through no longer holds the door true.
- Powered door reverses or stops: an obstruction, a misaligned or dirty photocell, a damaged safety edge, or an operator whose force setting no longer matches a door that has stiffened.
- Lock will not engage: the door has dropped or the frame has moved, so the latch no longer lines up with its keep.
Warning signs worth acting on before the door fails completely
- The door has become noticeably heavier to lift by hand over recent weeks.
- A spring has a visible gap in its coils, or looks stretched compared with the one on the other side.
- A cable is frayed, kinked, slack, or has jumped off its drum or pulley.
- The door judders, catches at the same point every time, or needs a shove to get going.
- Bright metal, flaking paint or rust streaks where the frame meets the brickwork.
- A powered door strains, hums or trips out, which usually means the operator is fighting a door that is no longer balanced.
- The safety edge or photocell on a powered door has been knocked, damaged or taped over by somebody trying to stop nuisance reversing.
A snapped spring or cable: what to do straight away
Springs, cables and the brackets they are fastened to hold stored energy even with the door shut, and releasing it without the right tools and training causes serious injuries. If a spring or cable has gone, the safe response is to stop using the door entirely rather than to try one more lift.
If the door is stuck open you have a security problem as well as a safety one, and most garage door companies treat a door that cannot be closed as an urgent call. Say on the phone what you heard, whether the door is open or shut, and whether a car is trapped inside, because that decides what the engineer brings.
- Stop using the door and, on a powered door, isolate the operator so nobody tries the remote.
- Keep people, pets and vehicles from under a door that is open or part open, because without a working spring it can come down hard.
- Do not pull the manual release on a raised door with a broken spring or cable, since nothing will be holding it up.
- Do not try to lift the door with a jack, a prop or extra hands, and do not touch the springs, cables, drums or bottom brackets.
- If the door is stuck open overnight, move anything valuable out of the garage and secure the internal door to the house.
- Call a garage door engineer rather than a general handyman, and mention if the door is on a shared drive or blocks access for others.
Safe checks and servicing for a British garage door
There is a clear line between what an owner can sensibly do and what needs an engineer. Looking, cleaning and lubricating the parts the manufacturer lists is fine. Anything that adjusts or releases the balance of the door is not. For a powered door, HSE expects it to be regularly checked, which may include inspection, testing and adjustment for safety, and to be maintained by competent contractors.
HSE also recommends keeping records of servicing, repair and testing. On a domestic door that is as simple as a folder with the handover pack and every invoice, but it matters if you rent the property out or sell it, and it gives the next engineer a history rather than a guess.
- Look, do not touch: with the door closed, check springs, cables, rollers, hinges and the frame for rust, fraying, gaps in coils and loose fixings.
- Balance check by feel: a well-balanced door moves smoothly with light effort; one that fights you or drops needs an engineer rather than more force.
- Keep the tracks and the roller door guides clear of grit and leaf litter, which is the single most useful thing an owner can do.
- Lubricate only what the manufacturer's instructions list, and keep lubricant off a roller door curtain and off rubber seals.
- Wash salt and road grime off the door and frame on coastal and roadside properties, since that is what drives corrosion.
- On a powered door, keep photocells clean and aligned and never tape over, move or disable a safety device.
- Book a service at the interval the manufacturer gives, and keep the paperwork with the handover pack.
Damp, corrosion and the British winter in an unheated garage
An unheated British garage spends much of the year close to the dew point. Warm damp air meets cold steel, condensation forms on the inside of the door and on the springs, and the parts that never dry out corrode quietly for years. That is why so many UK garage door failures are corrosion failures rather than wear failures, and why they cluster after a long wet winter.
Ventilation helps more than heating. A garage with some airflow dries out between wet spells; one sealed tight to keep draughts out holds the moisture in. If you are fitting a new door, this is the argument for aluminium curtains, galvanised or well-coated gear and a properly finished subframe, especially on an exposed or coastal site. If you are keeping the door you have, clearing the bottom track so water drains away rather than standing against the panel is worth doing before winter.
What happens during a garage door repair visit
- Diagnosis: the engineer operates the door by hand and, if powered, on the operator, checks the balance and inspects springs, cables, tracks, rollers and the frame.
- Making safe: a door with a broken spring or cable is secured before anything else, so it cannot fall while work goes on.
- Springs: a failed spring is replaced with one matched to the weight and travel of that door, and on a door with a pair both are often changed together so they wear evenly.
- Cables and drums: frayed cables are replaced and the drums or pulleys checked, since a worn drum will chew through a new cable.
- Tracks, rollers and pivots: bent track is straightened or replaced, worn rollers and bearings changed, and the door realigned in the opening.
- Frame and fixings: corroded subframe sections are treated or replaced, because a new spring on a failing frame is a short-lived repair.
- Powered doors: the operator's force and travel settings are reset to suit the repaired door, and the safety edge and photocells are tested before handover.
- Handover: the door is run several times, you are shown the manual release, and the work is recorded on an invoice worth filing.
Repair or replace: where the line falls on an older British door
Springs, cables, rollers and seals are wear parts and are expected to be replaced during a door's life, so a single failure on a sound door is a repair. The judgement gets harder when the frame is involved, because the subframe and lintel fixings are what everything else depends on.
- Repair when a spring, cable, roller or seal has failed on a door whose panel and frame are sound.
- Repair when a powered door's fault is in the operator, its control board or a safety device rather than in the door itself.
- Replace when the subframe has rusted through or the door no longer sits square in an opening that has moved.
- Replace when the panel is holed, badly corroded at the bottom edge or distorted from an impact.
- Replace when spares for the gear are discontinued, which is common on up-and-over doors fitted decades ago.
- Replace when repairs keep recurring, or when you want an insulated or powered door the existing one cannot become safely.
- LokalMatch helps at exactly this decision point. You describe the fault once, including the door type, roughly how old it is and what you heard when it failed, and matched garage door engineers covering your postcode contact you directly. Professionals pay for the requests they receive. LokalMatch does not carry out repairs, does not set prices and does not vet, rank or recommend any company, so checking insurance and references is still your job.
Garage Door Repair: frequently asked questions
Can I replace a garage door spring myself?
No. Garage door springs hold a large amount of stored energy even when the door is shut, and releasing it without the correct winding tools and training causes serious injuries. The same applies to the cables, drums and bottom brackets they are attached to. Spring and cable work is for a trained garage door engineer.
My garage door is suddenly far too heavy to lift. What has happened?
Almost certainly a spring has broken, so you are now lifting the full weight of the door with nothing counterbalancing it. Stop using the door, keep everyone from underneath it and call an engineer. If the door is stuck in the open position, do not pull the manual release on a powered door, because nothing is holding the door up.
Why does my powered garage door stop and go back up?
The operator is sensing resistance or a safety device has triggered. Check nothing is in the opening and that the photocells are clean, aligned and undamaged. It can also mean the door itself has stiffened through corrosion or a worn roller, so the operator meets more resistance than its force setting allows. If it keeps happening, have the door and the operator settings checked rather than turning the force up.
How often should a garage door be serviced in the UK?
Follow the manufacturer's stated interval, and keep the records. For a powered door, HSE expects it to be regularly checked, which may include inspection, testing and adjustment for safety, and maintained by competent contractors. In a damp or coastal garage it is worth looking over the springs, cables and frame yourself between services, since corrosion is the usual British cause of failure.
Is it worth repairing a garage door that is thirty years old?
Sometimes. If the panel and the steel subframe are sound, replacing a spring or a set of rollers is good value. If the subframe has corroded through, the door no longer sits square, or spares for the gear are no longer made, the repair is holding up something that will fail again. An engineer should tell you which of those you have before quoting.

What affects the cost of garage door repair
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Number, size and style of windows or doors
- Frame material and glass options
- Full-frame replacement or insert
- Repairs to rotted framing or sills
- Interior and exterior trim and capping
- Access, including upper floors
How to compare garage door technicians before you hire
- Look for an installer who measures on site and explains how the new window or door will be sealed and flashed.
- Ask whether the quote is for a full-frame replacement or an insert, and why they recommend it.
- Compare quotes on the same product type, glass options, installation method and interior and exterior trim.
- Ask who handles warranty issues: the installer, the manufacturer or both.
- For garage doors, choose a technician trained on springs and openers, since that work can be dangerous.
Questions to ask garage door technicians before you hire
- Will you replace the full frame or install an insert, and what's the difference for my home?
- How will you insulate and seal around the new units?
- Is interior and exterior trim included in the price?
- What does the manufacturer's warranty cover, and what does your installation warranty cover?
- How long will it take for the products to arrive once I order?
- Will your own crew do the installation?
When to call a pro for garage door repair
- Drafts, condensation or fog between the panes
- Windows or doors that stick, won't lock or let water in
- A garage door that's off track or has a broken spring: don't try to force it, and call a garage door technician.
Garage door repair permits and local rules
Some garage door repair work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
