Intumescent strips and smoke seals in Gosport, done to the evidence
Our intumescent strips and smoke seals service in Gosport is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Fire doors in Gosport protect escape routes in houses with integral garages, high-street shops and family homes after loft conversions alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Painted and missing seals are among the most common fire door defects nationally; in Gosport we replace them with the type and size the certification specifies. We check that each door in your Gosport 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.
On a typical job that means:
- Removal of damaged or painted seals
- Identification of the specified seals
- Intumescent strips in frame or leaf edge
- Check of gaps and closing after fitting
Rules and responsibilities in Gosport
The rules that apply to fire doors in Gosport 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 Gosport 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.

Common questions
Do you cover PO12 and nearby postcodes?
Yes. We cover Gosport including PO12, and nearby towns such as Portsmouth and Fareham. The survey and written quote are free.
What happens on a survey in Gosport?
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.
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.
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.
