Intumescent strips and smoke seals for Sandhurst buildings
Our intumescent strips and smoke seals service covers Sandhurst and the wider Berkshire area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
In and around Sandhurst, fire door work covers everything from care homes to houses with integral garages. 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 Sandhurst we replace them with the type and size the certification specifies. Seal replacement in Sandhurst 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.
As standard, the work covers:
- Identification of the specified seals
- Removal of damaged or painted seals
- Brush or blade smoke seals
- Check of gaps and closing after fitting
The regulations behind fire doors in Sandhurst
In Sandhurst, 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 Sandhurst 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.
Buildings and duty holders in Sandhurst
Typical settings for intumescent strips and smoke seals include schools, HMOs and blocks of flats. In Sandhurst, as anywhere, the duty holder varies: a responsible person for a workplace, a landlord or managing agent for a block or HMO, or a homeowner after building work. We adjust access, timing and paperwork to suit whoever commissions the work.

Questions from Sandhurst
Do you cover GU47 and nearby postcodes?
Yes. We cover Sandhurst including GU47, and nearby towns such as Crowthorne and Yateley. The survey and written quote are free.
How quickly can you survey in Sandhurst?
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.
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.
