Intumescent strips and smoke seals for Amersham buildings
From the HP7 postcode district outwards, we take on intumescent strips and smoke seals across Amersham for homes, blocks and workplaces.
Fire doors in Amersham protect escape routes in family homes after loft conversions, schools and small offices alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Painted and missing seals are among the most common fire door defects nationally; in Amersham we replace them with the type and size the certification specifies. Seal replacement in Amersham can be combined with any other remedials on the same inspection report.
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.
On a typical job that means:
- Intumescent strips in frame or leaf edge
- Identification of the specified seals
- Check of gaps and closing after fitting
- Removal of damaged or painted seals

Fire doors in Amersham 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.

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 Amersham
Do you cover HP7 and nearby postcodes?
Yes. We cover Amersham including HP7, and nearby towns such as Chesham and Chalfont St Peter. The survey and written quote are free.
What happens on a survey in Amersham?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
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.
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.
