Intumescent & Smoke Seal Replacement in Chesham

From the HP5 district outwards, we cover Chesham and neighbouring towns such as Amersham and Berkhamsted for fire door seal replacements.

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.

Intumescent & Smoke Seal Replacement in Chesham: questions

Which fire safety law applies in Chesham?

Chesham 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.

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.

Do you work in occupied buildings in Chesham?

Yes. Inspections and repairs in Chesham can be carried out in occupied flats, schools, care homes and workplaces, with doors kept closable at all times.

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.
