Intumescent strips and smoke seals in King's Lynn, done to the evidence
For property owners, landlords and managing agents in King's Lynn, we offer intumescent strips and smoke seals with one team for the survey, the product and the installation.
Around King's Lynn, care homes, small blocks of flats and family homes after loft conversions all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
We check that each door in your King's Lynn 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 King's Lynn we replace them with the type and size the certification specifies.
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
- Intumescent strips in frame or leaf edge
- Check of gaps and closing after fitting
- Brush or blade smoke seals

Common questions
Is King's Lynn within your coverage area?
It is. We cover King's Lynn in Norfolk and neighbouring towns such as Wisbech. There is no charge for the survey.
Can you work from an existing inspection report for my King's Lynn 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.
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.
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.
