Fire door repair and replacement costs
Repair costs depend on the defect, from a replacement seal or closer adjustment to rehanging a door. Replacement depends on the rating, size, hardware and access. Repairing a sound door is usually far cheaper than replacing it.

Repair or replace?
| Usually repairable | Usually needs replacing |
|---|---|
| Gaps that can be corrected by adjustment or a compliant edge strip | Doors that were never fit for purpose |
| Damaged or missing seals | Doors that can’t be traced to test evidence |
| Closers that don’t close or latch | Badly altered doors (letterboxes, cat flaps, holes) |
| Loose or non-rated hinges | Severe damage to the leaf or frame |
| Missing signage | Doors that can’t be repaired within their certification |
What affects repair costs
- The defect. Seals and closer adjustments are quick; rehanging or re-lipping a door takes longer.
- Parts. Fire-rated hinges, closers and glazing must match the door’s test evidence.
- Volume. Fixing many doors in one visit is more efficient than one-off call-outs.
- Agreed rates. A schedule of rates means small fixes don’t need re-quoting each time.
What affects replacement costs
- The fire rating (FD30 or FD60) and whether it needs smoke control
- Doorset or on-site assembly
- Size, glazing and hardware
- Flat entrance doors, which need lease checks and resident access
Planning the work
Start with anything that stops a door closing and latching, or that leaves a gap fire and smoke can pass through. Then work through the rest in priority order. Burnham’s inspection reports list repairs this way. Get a quote.
