Intumescent & Smoke Seal Replacement in Sudbury

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

Questions from Sudbury clients

Does regulation 10 apply to buildings in Sudbury?

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

Can you price remedial work in Sudbury from another company's report?

Yes. Send the report and we will price each line for your building in Sudbury, or revisit specific doors if the report lacks detail.

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.
