Intumescent strips and smoke seals for Blackheath buildings
Our intumescent strips and smoke seals service in Blackheath is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Fire doors in Blackheath protect escape routes in schools, shared houses and clinics 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 Blackheath we replace them with the type and size the certification specifies. We check that each door in your Blackheath 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:
- Check of gaps and closing after fitting
- Brush or blade smoke seals
- Intumescent strips in frame or leaf edge
- Removal of damaged or painted seals
Which fire door rules apply in Blackheath?
In Blackheath, 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. In London, the London Fire Brigade is the enforcing authority for fire safety law.
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 Blackheath 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.

Common questions
Is Blackheath within your coverage area?
It is. We cover Blackheath in Greater London and neighbouring towns such as Greenwich. There is no charge for the survey.
Can you work from an existing inspection report for my Blackheath 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.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
