What intumescent strips and smoke seals in Coleraine should include
We provide intumescent strips and smoke seals in Coleraine (BT52 and the surrounding postcodes), from the first survey through to a documented handover.
In and around Coleraine, fire door work covers everything from small offices to small blocks of flats. We plan each job around the people who use the building.
Painted and missing seals are among the most common fire door defects nationally; in Coleraine we replace them with the type and size the certification specifies. Seal replacement in Coleraine can be combined with any other remedials on the same inspection report.
Why seals fail
Seals are the most common defect on fire door inspections. They get painted over, pulled out, damaged by cleaning or simply worn by years of use. A painted brush seal no longer seals, and a strip of the wrong size may not close the gap in a fire. Our guide to seals explains the different types.
What you get:
- Intumescent strips in frame or leaf edge
- Intumescent pads to hinges and locks
- Removal of damaged or painted seals
- Check of gaps and closing after fitting

Questions from Coleraine
Do you cover BT52 and nearby postcodes?
Yes. We cover Coleraine including BT52, and nearby towns such as Ballymena and Derry. The survey and written quote are free.
What happens on a survey in Coleraine?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
How long do seals last?
It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.
Do all fire doors need smoke seals?
Only where the door is specified for smoke control, such as FD30S doors. Many doors on escape routes and flat entrances are specified this way.
