Intumescent strips and smoke seals: our service in Brentwood
From the CM14 postcode district outwards, we take on intumescent strips and smoke seals across Brentwood for homes, blocks and workplaces.
In and around Brentwood, fire door work covers everything from industrial estates to care homes. We plan each job around the people who use the building.
Painted and missing seals are among the most common fire door defects nationally; in Brentwood we replace them with the type and size the certification specifies. We check that each door in your Brentwood 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.
On a typical job that means:
- Removal of damaged or painted seals
- Intumescent pads to hinges and locks
- Identification of the specified seals
- Brush or blade smoke seals
Rules and responsibilities in Brentwood
The rules that apply to fire doors in Brentwood 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 Brentwood 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
Do you cover CM14 and nearby postcodes?
Yes. We cover Brentwood including CM14, and nearby towns such as Billericay and Hornchurch. The survey and written quote are free.
What happens on a survey in Brentwood?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
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.
