Intumescent strips and smoke seals in Penarth: what's involved
From the CF64 postcode district outwards, we take on intumescent strips and smoke seals across Penarth for homes, blocks and workplaces.
Fire doors in Penarth protect escape routes in houses with integral garages, care homes and small offices alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Painted and missing seals are among the most common fire door defects nationally; in Penarth we replace them with the type and size the certification specifies. We check that each door in your Penarth building closes and latches against its new seals before signing it off.
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.
Each installation includes:
- Intumescent strips in frame or leaf edge
- Removal of damaged or painted seals
- Brush or blade smoke seals
- Identification of the specified seals
The regulations behind fire doors in Penarth
Penarth is in Wales, where new and replacement fire doors are covered by the Building Regulations 2010 as applied in Wales, with the Welsh Approved Document B as guidance. The Regulatory Reform (Fire Safety) Order 2005 also applies, so responsible persons in workplaces and the common parts of blocks must keep fire doors maintained.
One difference from England: regulation 10 of the Fire Safety (England) Regulations 2022, with its quarterly and annual fire door checks, does not apply in Wales. Your fire risk assessment sets the checking regime instead, and we work to it.
Where intumescent strips and smoke seals fit in Penarth
From HMOs to schools, the requirement for intumescent strips and smoke seals in Penarth comes from the fire strategy or risk assessment for the building. We work from that document, or help you interpret your inspection report, before quoting.

Common questions
Do you work in Penarth?
Yes, we take on intumescent strips and smoke seals in Penarth and the surrounding area, including Cardiff and Barry. Send your postcode and a few details and we'll come back with survey dates.
How quickly can you survey in Penarth?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
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.
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.
