Intumescent strips and smoke seals: our service in Cardiff
We provide intumescent strips and smoke seals in Cardiff (CF10 and the surrounding postcodes), from the first survey through to a documented handover.
Fire doors in Cardiff protect escape routes in hotels, student accommodation and converted flats 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 Cardiff we replace them with the type and size the certification specifies. We check that each door in your Cardiff 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.
On a typical job that means:
- Identification of the specified seals
- Check of gaps and closing after fitting
- Removal of damaged or painted seals
- Brush or blade smoke seals
What the rules say for Cardiff
Because Cardiff 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 Cardiff comes from your fire risk assessment.
Who needs intumescent strips and smoke seals in Cardiff?
You are most likely to need intumescent strips and smoke seals if you look after schools, offices or HMOs. Whatever the building in Cardiff, we survey each opening and tell you which doors need work and which do not.

Questions from Cardiff
Is Cardiff within your coverage area?
It is. We cover Cardiff in South Glamorgan and neighbouring towns such as Penarth. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
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.
