Intumescent & Smoke Seal Replacement in Portsmouth

Whether it is a block of flats, a school or a care home in Portsmouth, our fire door seal replacements follow the same door-by-door method and report format.

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.

Questions from Portsmouth clients

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.

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.

Do you cover the area around Portsmouth?

Yes. As well as Portsmouth itself we cover nearby towns including Gosport, Fareham and Ryde.

Does regulation 10 apply to buildings in Portsmouth?

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