What intumescent strips and smoke seals in Mitcham should include
Looking for intumescent strips and smoke seals in Mitcham? We supply and fit certified fire doors and components across Mitcham and the wider Greater London area, working from a free survey and a fixed written quote.
Around Mitcham, clinics, purpose-built blocks of flats and restaurants 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.
Painted and missing seals are among the most common fire door defects nationally; in Mitcham we replace them with the type and size the certification specifies. We check that each door in your Mitcham 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:
- Brush or blade smoke seals
- Removal of damaged or painted seals
- Identification of the specified seals
- Check of gaps and closing after fitting
What the rules say for Mitcham
In Mitcham, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet. Enforcement of fire safety law in Mitcham sits with the London Fire Brigade.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Mitcham building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.

Questions from Mitcham
Do you cover CR4 and nearby postcodes?
Yes. We cover Mitcham including CR4, and nearby towns such as Morden and Wimbledon. The survey and written quote are free.
Can you work from an existing inspection report for my Mitcham 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.
