Get failed doors passing again
Our fire door repair service in London fixes the faults that make doors fail. We repair closers, hinges, seals, gaps and glazing with parts that keep the door’s fire rating intact.
Fire door repairs explained
A fire door repair puts right the parts that wear or get damaged. That means closers, hinges, seals, latches, glazing beads and small holes.
If the leaf and frame are sound, most failed doors can pass again after a repair. For a long list of faults, our fire door remedial works fix them in one programme.
A fire door was tested with certain hinges, seals and closers. Swapping in ordinary parts can quietly undo its fire rating.
We only use fire-rated parts that suit the door’s test evidence. Holes are filled with fire-rated repairs, never with filler or foam.
Repairs cost far less than new doors and cause less disruption. They also keep good doors out of landfill.
If a door is too far gone to repair, our fire door specialist team will tell you straight away and price a fire door replacement instead.

Bad repairs
A poor repair can be worse than no repair. These are the shortcuts we often have to undo. To spot the faults themselves, see our guide to common fire door defects.
Wood filler and foam burn through fast in a fire.
Fresh paint stops intumescent strips working.
Ordinary hinges can fail long before the door does.
Swapping fire glass for plain glass voids the door.
Non-fire-rated locks leave a weak spot in the leaf.
Trimming a door beyond its limits can void the rating.

What people search for before booking fire door repairs.
It depends on the fault. New seals usually cost £60–£140 per door, a new closer £120–£250 and a re-hang £80–£180, before VAT. Most repairs cost far less than a new doorset. Grouping several repairs into one visit lowers the cost, as travel and set-up are shared. You get a fixed price for each repair before we start.
Yes, if the leaf and frame are sound. Closers, hinges, seals, gaps, glazing beads and small holes can all be repaired. Doors that are split, warped or have no proof of rating usually need replacing.
Not if it is done right. Repairs must use fire-rated parts that suit the door’s test evidence. Filler, foam or ordinary hinges can quietly undo the rating. Every repair we make is recorded with before and after photos. That record shows the work kept the door within its test evidence.
We first re-hang the door and adjust the hinges. If the gap is still too wide, a matching hardwood edge strip can be fitted to bring it back to 2 to 4 mm. Wide gaps often come from worn hinges, so we check those first. Fixing the cause stops the gap opening up again a few months later.
Small holes, such as old lock cut-outs, can be repaired with fire-rated materials. Large holes or damage through the core usually mean a new door. Fire-rated repairs use matching timber or approved repair kits, not wood filler or foam. Filler burns through quickly, so a filled hole can let fire straight through the door.
Simple jobs like replacing a sign are fine. Repairs to closers, hinges, seals or the leaf should be done by someone competent, as the wrong parts can void the rating. If in doubt, ask a specialist to check the door after any work. A quick check now is cheaper than replacing a door that fails later.
The most common causes are a weak or badly adjusted closer, a door that has dropped on its hinges, or a door rubbing on its frame. All three can usually be fixed in one visit.
We can often visit within the week. Doors that will not close on an escape route are given priority. A fire door maintenance plan helps stop the same faults coming back. If a part has to be ordered, we can often make the door safe on the first visit and return to finish the repair once the part arrives.
