Intumescent strips and smoke seals in Windsor: what's involved
From the SL4 postcode district outwards, we take on intumescent strips and smoke seals across Windsor for homes, blocks and workplaces.
Windsor has a broad mix of buildings, including family homes after loft conversions, small offices and houses with integral garages, and the same fire door principles apply to all of them.
Painted and missing seals are among the most common fire door defects nationally; in Windsor we replace them with the type and size the certification specifies. Seal replacement in Windsor can be combined with any other remedials on the same inspection report.
Getting the specification right
The door's certification states the type, size and position of strips and seals: in the frame or the leaf edge, single or double, and whether a combined intumescent and smoke seal is used. Replacements must match. Swapping in a generic strip from a hardware shop can undermine the door's performance.
What you get:
- Removal of damaged or painted seals
- Identification of the specified seals
- Intumescent strips in frame or leaf edge
- Check of gaps and closing after fitting
Fire door law for Windsor properties
England's framework applies in Windsor. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in Windsor, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.
Which buildings in Windsor need intumescent strips and smoke seals?
From care homes to offices, the requirement for intumescent strips and smoke seals in Windsor 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.

It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
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.
