Intumescent & Smoke Seal Replacement in Durham

Need a fire door seal replacement in Durham? Tell us the building and roughly how many doors, and we will confirm a fixed price before booking.

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. We use the same method for buildings in Durham.

Intumescent & Smoke Seal Replacement in Durham: questions

Which fire safety law applies in Durham?

Durham is in England, so the Regulatory Reform (Fire Safety) Order 2005 applies, together with the Fire Safety (England) Regulations 2022 for multi-occupied residential buildings.

Do you cover the area around Durham?

Yes. As well as Durham itself we cover nearby towns including Chester-le-Street, Houghton-Le-Spring and Stanley.

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.

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.
