Fire door replacement: our service in Dartford
From the DA1 postcode district outwards, we take on fire door replacement across Dartford for homes, blocks and workplaces.
In and around Dartford, fire door work covers everything from industrial estates to HMOs. We plan each job around the people who use the building.
If your Dartford building has an inspection report or fire risk assessment, we quote against the same door references. We never leave a Dartford opening without a door; the new one is on site before the old one comes out.
Repair or replace?
Plenty of fire door faults can be fixed: worn seals, loose hinges, failed closers, small gaps. Replacement is the right call when the leaf is split, delaminated or badly damaged, when gaps are too large to correct within the manufacturer's guidance, when the door was never a fire door, or when unapproved holes and alterations have been made. We explain the reason for every replacement we recommend. Our repairs page covers what can be fixed.
On a typical job that means:
- Removal and disposal of the old door
- Assessment of repair versus replacement
- Certified leaf or full doorset
- Frame repair or replacement where needed
Which fire door rules apply in Dartford?
Fire doors in Dartford fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in Dartford above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

The need for fire door replacement usually arises in schools or blocks of flats, and sometimes HMOs. Each has its own pressures, such as residents at home or a building that must stay open, so we plan the sequence of work in Dartford to keep escape routes protected throughout.
