Getting fire door replacement right in Gwynedd
We provide fire door replacement across Gwynedd, covering 44 postcode districts from LL23 to LL78.
If a door in your Gwynedd building can be repaired rather than replaced, we will tell you. We never leave a Gwynedd opening without a door; the new one is on site before the old one comes out.
Wherever your building is in Gwynedd, the fire safety duties come from national rules, and our installation standard is the same.
After an inspection report
Most replacement work follows a fire door inspection or fire risk assessment. Send us the report and we will price each action, replacement or repair, door by door, so you can prioritise. Our guide to failed inspections explains how to read the findings.
Fire door law for Gwynedd properties
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.
The steps on a Gwynedd installation
- Review the inspection report or survey each door
- Recommend repair or replacement with reasons
- Order replacements to size
- Remove the old door only when the new one is on site
- Install, test and record each opening
- Dispose of old doors and hand over evidence

Fire door replacement questions
Do you provide fire door replacement across Gwynedd?
Yes. We cover all of Gwynedd. Surveys and written quotes are free.
How do I know if a fire door needs replacing?
A competent inspection will tell you. Typical reasons are serious damage, gaps that cannot be corrected, no evidence the door is a fire door, or unapproved alterations such as new holes or glazing.
Can you replace just the door and keep the frame?
Yes, if the frame is sound and compatible with the new leaf's certification. If not, we replace the whole doorset.
