Fire Stopping Around Doors in City of Westminster

From the SW1E district outwards, we cover City of Westminster and neighbouring towns such as Pimlico and London for fire stopping works.

In short: fire stopping is the sealing of gaps and openings in fire-resisting walls and floors so fire and smoke cannot pass through. Around a fire door it mainly means the gap between the door frame and the wall, which must be sealed as well as the door itself.
