Intumescent strips and smoke seals: our service in Richmond
If you need intumescent strips and smoke seals in Richmond, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
Fire doors in Richmond protect escape routes in purpose-built blocks of flats, shared houses and student accommodation alike. We adapt the programme to the building and its occupants, never the standard of the installation.
We check that each door in your Richmond building closes and latches against its new seals before signing it off. Painted and missing seals are among the most common fire door defects nationally; in Richmond we replace them with the type and size the certification specifies.
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:
- Removal of damaged or painted seals
- Intumescent pads to hinges and locks
- Identification of the specified seals
- Intumescent strips in frame or leaf edge
Which fire door rules apply in Richmond?
In Richmond, 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. Enforcement of fire safety law in Richmond sits with the London Fire Brigade.
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 Richmond 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.
Which buildings in Richmond need intumescent strips and smoke seals?
Typical settings for intumescent strips and smoke seals include offices, care homes and HMOs. In Richmond, 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
Do you work in Richmond?
Yes, we take on intumescent strips and smoke seals in Richmond and the surrounding area, including Isleworth and Hounslow. Send your postcode and a few details and we'll come back with survey dates.
Can you work from an existing inspection report for my Richmond 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.
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.
