A garage door that has stopped working properly leaves you with one straightforward question: pay to fix it, or put that money towards a new one? We carry out both repairs and full replacements, so we have no interest in steering you the wrong way. Plenty of the doors we see need nothing more than a new cable or a fresh remote battery, and some are past the point where any repair makes financial sense. This guide sets out how we make that call, so you can make it too.
When a Repair Is the Right Call
Repair is usually the right answer when one component has failed on a door that is otherwise sound. The structure of the door (the curtain, the guides and the frame) is straight, solid and free of serious rust; one part has simply worn out or given up. Typical examples include:
- A remote that no longer responds, or a flat battery in the remote system
- A safety edge fault that stops the door closing as it should
- A snapped or damaged cable on a newer door
- A broken spring or a worn spindle on a door in otherwise good condition
- A lock or handle that has seized, worn or been damaged
Faults like these rarely mean the door is finished. Our maintenance and repair service covers all of them, from motor assessments and safety edge checks through to cable and spring replacements. For a walk-through of the most frequent problems and how each one is put right, see our guide to common roller garage door faults and fixes.
Age matters even here. A snapped cable on a door fitted five years ago is a simple repair. The same fault on a door fitted twenty-five years ago deserves a conversation first, because at that age it is often the first sign of general wear rather than a one-off.
When Replacement Is the Better Buy
Four signs tell us a door has reached the point where repair money becomes wasted money.
- Repeated call-outs. If a different part has failed on each of the last few visits, the door is wearing out as a whole. Each fix buys months rather than years, and the bills quietly stack up.
- Obsolete parts. Many older doors use mechanisms that are no longer manufactured. Once spares become hard to source, every repair takes longer, costs more and does nothing to make the next failure less likely.
- A rusted, dented or damaged curtain. The curtain is most of the door. Replacing it costs a large share of a complete new door, and corrosion that has taken hold will keep spreading around any patch.
- An old uninsulated manual door facing a big bill. When the cost of the repair reaches a meaningful share of the price of a new insulated electric door, spending it on the old one rarely makes sense.
The Age Factor: 15 to 20 Years
As a working rule, a garage door that has passed 15 to 20 years of service is entering replacement territory. Three things change around that age. Parts availability declines, so repairs get slower and dearer. The door predates features that are now standard, such as a safety edge, automatic locking and insulated slats. And wear stops being local: fixing one part simply shifts the load onto the next weakest one.
We see this pattern most often in older suburban housing, where the garage still has the manual door it was built with. Many of the homes we visit around the east London border fall into this group (see our page on roller garage doors in Romford). If your door went in before the millennium and something major has just failed, replacement deserves a serious look.
The Hidden Costs of Nursing an Old Door
The repair bills are only the visible cost of keeping an old door going. The quieter costs add up too. An uninsulated single-skin door leaks heat all winter, which matters if the garage is attached to the house or has a room above it. Worn locks and a curtain that flexes make an old door a softer target than a modern one with automatic locking. A manual door also charges you in time and effort: out of the car, lift in the rain, back in the car, every single trip.
There is an opportunity cost as well. Money spent nursing a door at the end of its life leaves you exactly where you started, with an old door. The same money put towards a new one buys insulation, security, remote operation and a door that should not need another serious thought for years.
Not sure which side of the line your door falls on? We will tell you straight, with a fixed written quote for whichever route makes sense.

Every door is different, but this is how the common faults usually resolve at a survey.
| Fault type | Usual recommendation | Why |
|---|---|---|
| Faulty remote or flat battery | Repair | Quick, inexpensive fix on a door of any age. |
| Safety edge fault | Repair | Worth putting right promptly for safety. |
| Snapped or damaged cable | Repair | Straightforward on a newer, structurally sound door. |
| Broken spring or worn spindle | Repair | Sensible provided the rest of the door is in good condition. |
| Faulty motor | Assess first | Repair if parts are available; replace if the system is obsolete. |
| Rusted, dented or damaged curtain | Replace | Curtain replacement costs a large share of a new door. |
| Several faults in the last year or two | Replace | Repeated call-outs cost more than they solve. |
| Old uninsulated manual door needing a big repair | Replace | Put the repair money towards an insulated electric door. |
"Usual recommendation" is doing some work in that table. A broken spring on a rust-free ten-year-old door is a repair. The same spring on a corroded twenty-five-year-old door probably is not. Age and overall condition always decide the borderline cases, which is why we look at the whole door before quoting for any of it.
How Replacement Pricing Works
If the answer is replacement, the numbers are less daunting than most people expect. A made-to-measure insulated electric roller garage door typically costs between £1,275 and £4,000 installed, depending on the size of the opening, the slat profile and the finish. Single doors sit in the lower half of that range and doubles in the upper half. Our breakdown of electric roller garage door costs in Essex explains what moves the price, and our garage door cost calculator gives you an instant estimate from a few measurements before you speak to anyone.
That figure is always the installed price, and every door includes the electric motor, two remote controls, a safety edge, automatic locking and a manual override for power cuts. The process starts with a free on-site survey and a fixed written quote with no obligation. Your door is then manufactured to your measurements and fitted by our own team, with most installations completed in a single visit, typically within half a day. Our roller garage door installation guide walks through the whole process, from taking out the old door to safety checks and handover.
