Intumescent strips and smoke seals: our service in East Sussex
Across East Sussex, from Brighton to Eastbourne, we survey, supply and fit intumescent strips and smoke seals for homes, blocks of flats and workplaces.
Painted and missing seals are among the most common fire door defects nationally; in East Sussex we replace them with the type and size the certification specifies. We check that each door in your East Sussex building closes and latches against its new seals before signing it off.
East Sussex has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
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.
Which fire door rules apply in East Sussex?
The rules that apply to fire doors in East Sussex 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 East Sussex 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.

What does intumescent strips and smoke seals cost in East Sussex?

Intumescent strips and smoke seals questions
Do you provide intumescent strips and smoke seals across East Sussex?
Yes. We cover all of East Sussex, including Brighton and Eastbourne. Surveys and written quotes are free.
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.
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.
