Intumescent & Smoke Seal Replacement in Potters Bar

We provide fire door seal replacements for buildings in Potters Bar and the EN6 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.

Common questions in Potters Bar

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 Potters Bar?

Yes. As well as Potters Bar itself we cover nearby towns including Hadley Wood, Barnet and Enfield Town.

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.

Which fire safety law applies in Potters Bar?

Potters Bar 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.
