Intumescent & Smoke Seal Replacement in Portslade

We provide fire door seal replacements for buildings in Portslade and the BN41 postcode district, from single doors to whole blocks and estates.

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 Portslade: questions

Which fire safety law applies in Portslade?

Portslade is in England, so the Regulatory Reform (Fire Safety) Order 2005 applies, together with the Fire Safety (England) Regulations 2022 for multi-occupied residential 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 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 Portslade from another company's report?

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