Intumescent strips and smoke seals across Gwynedd

Intumescent strips and smoke seals in Gwynedd, done to the evidence

Our intumescent strips and smoke seals service covers all of Gwynedd, across postcode districts including LL23, LL78 and LL57.

We check that each door in your Gwynedd building closes and latches against its new seals before signing it off. Painted and missing seals are among the most common fire door defects nationally; in Gwynedd we replace them with the type and size the certification specifies.

Gwynedd 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.

Pads, linings and hidden protection

Fire doors also rely on intumescent material you cannot see: pads behind hinges, linings around lock bodies and glazing seals. Where these are missing or damaged, we fit the correct items as part of the work.

Which fire door rules apply in Gwynedd?

Because Gwynedd 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 Gwynedd comes from your fire risk assessment.
