Intumescent & Smoke Seal Replacement in Croydon

We provide fire door seal replacements for buildings in Croydon and the CR7 postcode district, from single doors to whole blocks and estates.

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 Croydon.

Intumescent & Smoke Seal Replacement in Croydon: questions

Do you cover the area around Croydon?

Yes. As well as Croydon itself we cover nearby towns including South Croydon, Wallington and Carshalton.

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.

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.

Which fire safety law applies in Croydon?

Croydon 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.
