Intumescent strips and smoke seals for Braintree buildings
Looking for intumescent strips and smoke seals in Braintree? We supply and fit certified fire doors and components across Braintree and the wider Essex area, working from a free survey and a fixed written quote.

Seal replacement in Braintree can be combined with any other remedials on the same inspection report. We check that each door in your Braintree 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.
As standard, the work covers:
- Identification of the specified seals
- Intumescent strips in frame or leaf edge
- Brush or blade smoke seals
- Intumescent pads to hinges and locks
Rules and responsibilities in Braintree
The rules that apply to fire doors in Braintree are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts.
Where a Braintree block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

Questions from Braintree
Do you work in Braintree?
Yes, we take on intumescent strips and smoke seals in Braintree and the surrounding area, including Witham and Chelmsford. Send your postcode and a few details and we'll come back with survey dates.
How quickly can you survey in Braintree?
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.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
