Intumescent & Smoke Seal Replacement in Sunderland, Tyne and Wear: every door logged, photographed and graded, with a clear price for anything that needs putting right.

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.

Common questions in Sunderland

What is the difference between an intumescent strip and a smoke seal?

An intumescent strip expands in heat to seal the gap during a fire. A smoke seal, often a brush or blade, blocks cold smoke at lower temperatures. Smoke control doors, marked with an S such as FD30S, need both.

Does regulation 10 apply to buildings in Sunderland?

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

Do you cover the area around Sunderland?

Yes. As well as Sunderland itself we cover nearby towns including Seaham, Washington and Houghton-Le-Spring.

Can intumescent strips be painted?

Brush and fin smoke seals should never be painted, because paint stops them working. Some intumescent strips tolerate a light coat, but the safest rule is to mask all seals before decorating and replace any that have been painted.
