Fire doors are intended to help resist the spread of fire and smoke when they form part of an appropriate fire safety strategy. Their performance depends on the complete doorset and the quality of installation, not simply the door leaf itself. Gaps, seals, frames, closers, hinges and associated hardware all matter.
We provide fire door installation across London for landlords, managing agents and commercial property teams. Work can be planned in response to a fire risk assessment, refurbishment programme or identified defects, with the scope agreed around the property and the doors concerned.

A fire door should operate correctly in everyday use while being suitable for its intended fire safety role. That means installation needs to consider the opening, frame, door leaf, ironmongery, seals, closing action and interfaces with surrounding construction. We start by establishing what is required at the property and whether any existing doors, frames or openings create complications. The installation scope is then planned so each door can be completed carefully and checked before handover.
Installation of suitable fire doorsets where new or replacement doors are required as part of the agreed fire safety scope.
We consider the condition and suitability of the opening and frame because the surrounding construction is part of the overall installation.
Relevant hardware is selected and fitted so the door can operate properly and close as intended.
Installation details around the leaf, frame and threshold are checked because excessive or inconsistent gaps can affect performance.
We work on doors serving common parts, corridors, stairways, offices and other locations where fire-resisting doors may be required.
| Service | Estimated Cost | Average |
|---|---|---|
| Standard replacement fire doorset | £900–£1,600 | £1,250 |
| Higher-specification or complex doorset | £1,400–£2,500+ | £1,900 |
| Multiple-door project | Quoted by scope | Project dependent |
Costs vary significantly with door rating, dimensions, glazing, hardware, frame condition, access, finishing and surrounding construction. A site-specific quotation should be obtained before work begins.

We treat the frame, hardware, seals, gaps and closing action as essential parts of the installation.
We organise work with property managers to reduce disruption where buildings remain in everyday use.
Where door work follows an assessment, we can help keep the remedial programme aligned with the wider fire safety priorities.

Free — no obligations

We establish which doors are involved and review any available assessment findings, specifications or building information.
The openings, dimensions and relevant surrounding conditions are checked before the installation scope is confirmed.
The door, frame and required components are installed with attention to fit, operation and the agreed specification.
Operation, closing action and visible installation details are reviewed before the work is handed back.
