Intumescent & Smoke Seal Replacement in Hertfordshire
Intumescent & Smoke Seal Replacement throughout Hertfordshire: from Watford to Hemel Hempstead, every door is inspected, photographed and logged, and remedial work is priced door by door.
Intumescent & Smoke Seal Replacement: 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 Hertfordshire: questions
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.
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.
Does regulation 10 apply to buildings in Hertfordshire?
Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Hertfordshire is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those buildings.
Do you work in occupied buildings in Hertfordshire?
Yes. Inspections and repairs in Hertfordshire can be carried out in occupied flats, schools, care homes and workplaces, with doors kept closable at all times.
