What intumescent strips and smoke seals in Clwyd should include
Our intumescent strips and smoke seals service runs throughout Clwyd. Main towns include Wrexham, Buckley and Deeside, and we cover the smaller places in between.
Painted and missing seals are among the most common fire door defects nationally; in Clwyd we replace them with the type and size the certification specifies. We check that each door in your Clwyd building closes and latches against its new seals before signing it off.
Clwyd has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
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.
Which fire door rules apply in Clwyd?
Because Clwyd is in Wales, we work to the Building Regulations as they apply in Wales and to the Welsh version of Approved Document B. The responsible person duties under the Fire Safety Order 2005 still apply to workplaces and common parts.
England's fire door checking rules for tall residential buildings do not apply in Wales, so the checking frequency for doors in Clwyd comes from your fire risk assessment.

Common questions
Do you provide intumescent strips and smoke seals across Clwyd?
Yes. We cover all of Clwyd, including Wrexham and Buckley. Surveys and written quotes are free.
Can I just add intumescent strips to an ordinary door?
No. Strips do not turn an ordinary door into a fire door. They only work as part of a door that was tested and certified with them.
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.
