Intumescent & Smoke Seal Replacement in Carshalton

We provide fire door seal replacements for buildings in Carshalton and the SM5 postcode district, from single doors to whole blocks and estates.

In short: 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 Carshalton: 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.

Does regulation 10 apply to buildings in Carshalton?

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

Can I just stick new seals over the old ones?

No. Seals should be fitted into the groove after the old seal is removed, in the size and type the door was tested with.

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

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