Intumescent & Smoke Seal Replacement in Windsor

Windsor landlords, managing agents and facilities teams can book fire door seal replacements with straightforward reports and fixed prices.

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.

Questions from Windsor clients

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.

Which fire safety law applies in Windsor?

Windsor 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.

Do you work in occupied buildings in Windsor?

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

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.
