Fire door not self-closing properly? Seal damaged or hardware missing? A fire door that doesn't close or seal correctly isn't meeting its safety purpose. We repair and upgrade fire door hardware for blocks of flats, commercial premises, and HMOs across London.
What We Fix
Closers, intumescent seals, hinges, latches and alignment — we repair fire doors in HMOs, blocks of flats, and commercial premises to restore correct function and compliance.
Self-closing devices (overhead closers and concealed floor springs) are the most common fire door fault. We fit compliant closers that ensure the door closes fully from any position.
Intumescent strips and smoke seals replaced around the door frame. These expand in fire conditions to seal the gap — essential for fire door compliance.
Fire doors require specific hinges rated to the door specification. We replace worn or missing hinges with compliant alternatives to maintain the door's fire rating.
Latches and locks on fire doors must allow rapid egress. We replace faulty latches, dead bolts, and panic hardware to meet regulatory requirements.
Fire doors must have correct, even gaps around all edges (typically 3mm). We rehang and adjust fire doors to meet the required tolerances.
Regular inspection and repair of fire doors in HMOs and residential blocks. We work with landlords, managing agents, and property managers across London.

FAQ
In many cases hinges can be tightened, re-fixed, or replaced individually without replacing the whole door. We assess each hinge and recommend the minimum work needed to restore correct fire-rated operation.
An intumescent seal expands in heat to block smoke and flames at the door edges. It should be replaced if it is cracked, compressed, or missing — or if the door fails a close-clearance inspection. We carry replacement seals for most common door sizes.
Yes. We repair fire doors in flats, HMOs, blocks of flats, offices, and commercial premises. We are familiar with the compliance requirements for FD30 and FD60 rated doors.
