Need a fire door seal replacement in Chester-le-Street? Tell us the building and roughly how many doors, and we will confirm a fixed price before booking.

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 Chester-le-Street.

Chester-le-Street FAQs

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.

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.

Can you price remedial work in Chester-le-Street from another company's report?

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