Intumescent & Smoke Seal Replacement in Derby

Whether it is a block of flats, a school or a care home in Derby, 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.

Derby FAQs

Does regulation 10 apply to buildings in Derby?

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

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

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.

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.
