Intumescent strips and smoke seals: our service in Southampton
We provide intumescent strips and smoke seals in Southampton (SO14 and the surrounding postcodes), from the first survey through to a documented handover.
Fire doors in Southampton protect escape routes in student accommodation, hotels and schools alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Seal replacement in Southampton can be combined with any other remedials on the same inspection report. We check that each door in your Southampton 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.
Each installation includes:
- Check of gaps and closing after fitting
- Identification of the specified seals
- Intumescent pads to hinges and locks
- Intumescent strips in frame or leaf edge
Fire door law for Southampton properties
Fire doors in Southampton fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in Southampton above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Common questions
Do you work in Southampton?
Yes, we take on intumescent strips and smoke seals in Southampton and the surrounding area, including Hythe and Totton. Send your postcode and a few details and we'll come back with survey dates.
Can you work from an existing inspection report for my Southampton building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
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.
