Intumescent & Smoke Seal Replacement in Gwynedd
Across Gwynedd, including rural and island locations, we carry out fire door seal replacements for landlords, housing providers, schools and businesses.
Intumescent & Smoke Seal Replacement: 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 Gwynedd: questions
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.
Does regulation 10 apply in Gwynedd?
No. Gwynedd is in Wales and regulation 10 is English law. The Fire Safety Order 2005 still requires fire doors to be maintained, and many Welsh landlords follow the same quarterly and annual routine as good practice.
Do you work in occupied buildings in Gwynedd?
Yes. Inspections and repairs in Gwynedd can be carried out in occupied flats, schools, care homes and workplaces, with doors kept closable at all times.
