Intumescent & Smoke Seal Replacement in Greater London

We provide fire door seal replacements across Greater London, including London, Brent and Islington, with the same report format and pricing wherever your buildings are.

Intumescent & Smoke Seal Replacement: Intumescent seals are strips set into the edge of a fire door or its frame that expand when heated to close the gap around the door. Smoke seals, usually brush or fin seals, block cold smoke before the intumescent reacts. Both are part of the door's tested performance.

Intumescent & Smoke Seal Replacement by town in Greater London

Intumescent & Smoke Seal Replacement in Greater London: questions

Will new seals fix a door with big gaps?

No. Seals only work within the gap they were tested with. Gaps outside tolerance need the door adjusting first.

Can I just stick new seals over the old ones?

No. Seals should be fitted into the groove after the old seal is removed, in the size and type the door was tested with.

Does regulation 10 apply to buildings in Greater London?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Greater London is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those buildings.

How quickly can you inspect fire doors in Greater London?

It depends on the number of doors and access. Tell us what you need and we will give you the earliest date when you call, and confirm it in writing.
