Intumescent & Smoke Seal Replacement in Harlow

Whether it is a block of flats, a school or a care home in Harlow, our fire door seal replacements follow the same door-by-door method and report format.

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 Harlow.

Harlow FAQs

Do you work in occupied buildings in Harlow?

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

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 Harlow?

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

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.
