Intumescent strips and smoke seals in Llanelli: what's involved
Our intumescent strips and smoke seals service in Llanelli is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Llanelli has a broad mix of buildings, including family homes after loft conversions, small blocks of flats and care homes, and the same fire door principles apply to all of them.
Painted and missing seals are among the most common fire door defects nationally; in Llanelli we replace them with the type and size the certification specifies. We check that each door in your Llanelli 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.
As standard, the work covers:
- Intumescent pads to hinges and locks
- Brush or blade smoke seals
- Removal of damaged or painted seals
- Check of gaps and closing after fitting
Fire door law for Llanelli properties
Fire door work in Llanelli follows Welsh building regulations and the Welsh Approved Document B. The Fire Safety Order 2005 covers workplaces and the shared parts of residential buildings here too, placing the duty on the responsible person.
The English regulation 10 checking regime does not extend to Llanelli, so how often doors are checked comes from the fire risk assessment. We hand over evidence that fits whatever regime your assessor sets.

Common questions
Do you work in Llanelli?
Yes, we take on intumescent strips and smoke seals in Llanelli and the surrounding area, including Gorseinon and Swansea. Send your postcode and a few details and we'll come back with survey dates.
Can you work from an existing inspection report for my Llanelli building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
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 smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
