Intumescent strips and smoke seals in Leatherhead: what's involved
For property owners, landlords and managing agents in Leatherhead, we offer intumescent strips and smoke seals with one team for the survey, the product and the installation.
In and around Leatherhead, fire door work covers everything from houses with integral garages to small blocks of flats. We plan each job around the people who use the building.
Painted and missing seals are among the most common fire door defects nationally; in Leatherhead we replace them with the type and size the certification specifies. We check that each door in your Leatherhead building closes and latches against its new seals before signing it off.
Pads, linings and hidden protection
Fire doors also rely on intumescent material you cannot see: pads behind hinges, linings around lock bodies and glazing seals. Where these are missing or damaged, we fit the correct items as part of the work.
Each installation includes:
- Intumescent pads to hinges and locks
- Identification of the specified seals
- Intumescent strips in frame or leaf edge
- Brush or blade smoke seals
The regulations behind fire doors in Leatherhead
Fire doors in Leatherhead fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in Leatherhead above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Questions from Leatherhead
Do you cover KT22 and nearby postcodes?
Yes. We cover Leatherhead including KT22, and nearby towns such as Epsom and Ewell. The survey and written quote are free.
Can you work from an existing inspection report for my Leatherhead 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.
