What intumescent strips and smoke seals in Leicester should include
If you need intumescent strips and smoke seals in Leicester, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
Fire doors in Leicester protect escape routes in shared houses, care homes and purpose-built blocks of flats alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Seal replacement in Leicester can be combined with any other remedials on the same inspection report. We check that each door in your Leicester 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 pads to hinges and locks
- Identification of the specified seals
- Brush or blade smoke seals
- Check of gaps and closing after fitting
Fire door law for Leicester properties
In Leicester, 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.
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 Leicester 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.
Where intumescent strips and smoke seals fit in Leicester
From blocks of flats to schools, the requirement for intumescent strips and smoke seals in Leicester 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.

- Identify door certification and seal specification
- Remove failed seals and clean the grooves

Questions
Do you cover LE1 and nearby postcodes?
Yes. We cover Leicester including LE1, and nearby towns such as Oadby and Wigston. The survey and written quote are free.
Can you work from an existing inspection report for my Leicester 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.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
