What intumescent strips and smoke seals in Winchester should include
When you book intumescent strips and smoke seals in Winchester, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
Winchester has a broad mix of buildings, including light industrial buildings, houses with integral garages and care homes, and the same fire door principles apply to all of them.
We check that each door in your Winchester building closes and latches against its new seals before signing it off. Painted and missing seals are among the most common fire door defects nationally; in Winchester we replace them with the type and size the certification specifies.
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.
On a typical job that means:
- Check of gaps and closing after fitting
- Identification of the specified seals
- Brush or blade smoke seals
- Intumescent strips in frame or leaf edge
The regulations behind fire doors in Winchester
The rules that apply to fire doors in Winchester 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 Winchester 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.

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.
How long do seals last?
It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.
