Intumescent strips and smoke seals in Chelmsford, done to the evidence
For property owners, landlords and managing agents in Chelmsford, we offer intumescent strips and smoke seals with one team for the survey, the product and the installation.
Around Chelmsford, GP surgeries, HMOs and schools 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 Chelmsford we replace them with the type and size the certification specifies. We check that each door in your Chelmsford building closes and latches against its new seals before signing it off.
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.
Each installation includes:
- Intumescent pads to hinges and locks
- Identification of the specified seals
- Check of gaps and closing after fitting
- Removal of damaged or painted seals
What the rules say for Chelmsford
In Chelmsford, 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 Chelmsford 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
Do you work in Chelmsford?
Yes, we take on intumescent strips and smoke seals in Chelmsford and the surrounding area, including Billericay and Witham. 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 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.
