Intumescent & Smoke Seal Replacement in Catford

Need a fire door seal replacement in Catford? Tell us the building and roughly how many doors, and we will confirm a fixed price before booking.

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 Catford

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.

Does regulation 10 apply to buildings in Catford?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Catford 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 Catford?

Yes. Inspections and repairs in Catford 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.
