Intumescent & Smoke Seal Replacement in Lisburn

Intumescent & Smoke Seal Replacement in Lisburn, County Antrim: every door logged, photographed and graded, with a clear price for anything that needs putting right.

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. We use the same method for buildings in Lisburn.

Lisburn FAQs

Does regulation 10 apply in Lisburn?

No. Lisburn is in Northern Ireland, where the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 apply.

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

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

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.

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.
