How often should fire doors be maintained?

Planned maintenance is normally bolted onto the inspection cycle: communal fire doors in buildings over 11m must be inspected quarterly under the 2022 Regulations, flat entrance doors annually. Most defects spotted at inspection are minor and resolved on the same visit — we can quote a combined inspect-and-remediate programme.

Will tenants need to be home?

No — for flat entrance doors we can usually work from communal side and a one-time access window. We notify tenants in writing 48 hours ahead, leave the door fully operable, and finish each flat in 60–90 minutes.

Can you maintain doors I didn't install?

Yes. We work on doors fitted by anyone — we check the existing certification first, log what's there, and quote against what each door needs to bring it back into compliance.

What if a door is beyond repair?

Some doors (heavily damaged leaves, non-certified frames, doors with no traceable spec) are not economic to maintain. We quote replacement separately under our Fire Door Installation service, with the full certification pack for the new door.

Do you offer emergency call-outs?

Yes — we can attend within 24–48 hours for an emergency make-safe (broken closer, smashed glazing, forced lock) and then return for a full remedial visit. Call 07859 992855.

What paperwork do I get after a maintenance visit?

Updated per-door record listing parts replaced, date, engineer's signature and before/after photos. The complete pack is reissued so your next inspection cycle starts from a documented baseline.

Are you qualified to maintain fire doors?

Yes. Daniel Daly holds the FireQual Fire Door Maintenance qualification (Programme Ref: QFD026, awarded 06/02/2026 by UK Fire Door Training, Certificate CQ023878). Every maintenance visit is carried out by or under the supervision of a qualified competent person.

Service Overview

Fire Door Maintenance — what's actually involved

What it is

Fire door maintenance is the planned and reactive work required to keep an installed fire door performing to its certified FD30 or FD60 rating — replacing failed intumescent and smoke seals, re-tensioning or replacing overhead closers, refitting or upgrading hinges and latches, easing leaves that have dropped or are catching, adjusting gaps back to the 2–4mm tolerance and reissuing the per-door compliance documentation.

Who it's for

Landlords with HMOs, flat entrance doors and communal doors; managing agents responsible for multi-occupancy blocks; housing associations; care homes, GP surgeries, schools and commercial premises with a duty under the Regulatory Reform (Fire Safety) Order 2005. If an inspection report (yours or ours) has flagged remedials, this is the work that closes them out.

When you need it

After a quarterly or annual inspection identifies defects under the Fire Safety (England) Regulations 2022; after vandalism, forced entry or moving-in damage; when an audit by Merseyside Fire & Rescue, an insurer or a buyer's solicitor has produced a remedial list; or as part of a planned preventative maintenance programme. The most common trigger is failed seals and broken closers — both easy fixes if caught early.

Why professional matters

An untrained handyman can void a door's certification simply by fitting the wrong-grade screws, the wrong intumescent profile or a non-tested closer. Maintenance work has to be carried out by a competent person and recorded — otherwise it does nothing for your compliance position. Daniel Daly holds the FireQual Fire Door Maintenance qualification (Programme Ref: QFD026, awarded 06/02/2026 by UK Fire Door Training), and every remedial we carry out is fully fire compliant and documented using OneTrace.

What happens if it's ignored

The cost of leaving it — or getting it wrong

Failed seals nobody noticed for two years

Intumescent and smoke seals shrink, get painted over or get cut by ironmongery changes. A 50mm gap in a head seal renders the whole door non-compliant — and it's invisible without lifting the seal.

Closers that don't latch from the half-open position

A self-closer that's been wound down or has lost spring tension won't pull the door fully home from 30°. In a real fire the door sits open. Fixed in 20 minutes if caught; catastrophic if it isn't.

DIY repairs that void the certification

An over-sized hinge cut, a non-tested replacement closer, a self-tapping screw into the leaf core — small repairs done by an untrained fitter take the door outside its tested assembly. The leaf may look fine but its FD rating is gone.

No paperwork to evidence the work was done

Maintenance carried out without a per-door record (parts used, date, signature, photo log) gives you nothing to show an insurer or fire officer. From a compliance standpoint it didn't happen.

Our Process

A defined system — so you know exactly what happens next

Step 1
Defect survey & schedule
We walk every door, log the defects against the door's existing certification (or create one if missing), and produce a fixed-price remedial schedule. You see exactly what's being replaced and why.
Step 2
Parts sourced to the data sheet
Replacement seals, closers, hinges and latches ordered to match the door's original specification — same profile, same grade, same manufacturer where possible. Substitutions only where a like-for-like is no longer made.
Step 3
On-site remedial works
Seals replaced continuously around head and jambs, closers re-tensioned or swapped, hinges replaced with intumescent pads where required, latches realigned, gaps adjusted back to 2–4mm tolerance. Each door photographed before and after.
Step 4
Re-test and sign-off
Every door tested for positive latching from the half-open position and free swing without binding. Closer pressure adjusted to balance positive close with usability for tenants.
Step 5
Updated compliance pack
Each door's record updated with the parts replaced, the date, the engineer's signature and photos. The whole pack reissued so your next quarterly or annual check starts from a clean baseline.

In Detail

Materials, methods and the situations they suit

Most fire door failures at audit are maintenance failures, not installation failures — the door was fine on the day it was fitted and has degraded since. Below is the level of detail we work to on every maintenance visit across Merseyside, and the parts of a fire door that most commonly need attention.

Intumescent and smoke seals — the most common failure

Intumescent strips expand above ~200°C to seal the gap between leaf and frame. Smoke seals (brush or fin) block cold smoke before the fire takes hold. They fail by shrinkage, paint contamination, mechanical damage from ironmongery changes, and degradation over a 10–15 year service life. We replace continuous lengths around head and jambs (not just packed sections at the latch), match the original profile and grade, and re-route into existing rebates so the leaf still closes onto a flush face.

Overhead closers — adjustment, replacement and grading

Grade-13 closers degrade by losing hydraulic damping or spring tension. Symptom: door slams, door doesn't latch from half-open, or closer leaks oil. We adjust closing speed and latching action where possible, replace the unit where not, and re-grade to match the door's weight and width — a Grade 3 closer on a 1000mm leaf is a frequent finding and a guaranteed audit fail.

Hinges, latches and ironmongery

CE-marked hinges (minimum 3 per leaf on a heavy fire door), with intumescent hinge pads where the data sheet requires. We replace hinges that have dropped or worn, refit hinge bolts where they've been removed, and realign latches that are catching. Where a leaf has dropped we ease the linings and re-set the hinge housings rather than packing the leaf — packing changes the gap geometry and the FD rating.

Gap tolerances and threshold integrity

Fire doors require gaps of 2–4mm at head and jambs and 8–10mm at threshold (or as the data sheet specifies). Doors drift outside tolerance through frame movement, leaf warp and floor build-up from new carpets. We measure with a feeler gauge, adjust hinge positions or plane edges within the leaf's tested limits, and replace threshold seals or drop-down smoke seals where the gap is excessive.

Signage and final inspection

'Fire Door — Keep Shut' signage must be present on both faces of every fire door under BS 5499. Missing or peeling signage is a quick audit fail — we replace where needed. Final inspection on every visit confirms positive latching, free swing, intact seals, certified ironmongery and complete signage. The visit isn't closed until the door operates correctly.
