Intumescent strips and smoke seals: our service in Coulsdon
From the CR5 postcode district outwards, we take on intumescent strips and smoke seals across Coulsdon for homes, blocks and workplaces.
Around Coulsdon, mixed-use office buildings, schools and care homes all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
Painted and missing seals are among the most common fire door defects nationally; in Coulsdon we replace them with the type and size the certification specifies. Seal replacement in Coulsdon 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.
On a typical job that means:
- Brush or blade smoke seals
- Check of gaps and closing after fitting
- Identification of the specified seals
- Removal of damaged or painted seals
The regulations behind fire doors in Coulsdon
England's framework applies in Coulsdon. 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. Enforcement of fire safety law in Coulsdon sits with the London Fire Brigade.
For blocks over 11 metres in Coulsdon, 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.

Do you cover CR5 and nearby postcodes?
Yes. We cover Coulsdon including CR5, and nearby towns such as Purley and Banstead. The survey and written quote are free.
How quickly can you survey in Coulsdon?
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.
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.
