Intumescent strips and smoke seals: our service in Eltham
Looking for intumescent strips and smoke seals in Eltham? We supply and fit certified fire doors and components across Eltham and the wider Greater London area, working from a free survey and a fixed written quote.
Buildings in and around Eltham range from care homes to hotels and schools. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Painted and missing seals are among the most common fire door defects nationally; in Eltham we replace them with the type and size the certification specifies. We check that each door in your Eltham building closes and latches against its new seals before signing it off.
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.
What you get:
- Intumescent pads to hinges and locks
- Brush or blade smoke seals
- Intumescent strips in frame or leaf edge
- Check of gaps and closing after fitting
Rules and responsibilities in Eltham
England's framework applies in Eltham. 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. In London, the London Fire Brigade is the enforcing authority for fire safety law.
For blocks over 11 metres in Eltham, 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.

Questions from Eltham
Do you work in Eltham?
Yes, we take on intumescent strips and smoke seals in Eltham and the surrounding area, including Blackheath and Welling. Send your postcode and a few details and we'll come back with survey dates.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
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.
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.
