Intumescent & Smoke Seal Replacement in Merthyr Tydfil: 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.

Do you work in occupied buildings in Merthyr Tydfil?

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

Which fire safety law applies in Merthyr Tydfil?

The Regulatory Reform (Fire Safety) Order 2005 applies in Wales, and the Fire Safety Act 2021 confirmed flat entrance doors in multi-occupied residential buildings are within scope.

Will new seals fix a door with big gaps?

No. Seals only work within the gap they were tested with. Gaps outside tolerance need the door adjusting first.
