Intumescent strips and smoke seals: our service in Portishead
Our intumescent strips and smoke seals service covers Portishead and the wider Somerset area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
Portishead has a broad mix of buildings, including family homes after loft conversions, care homes and light industrial buildings, and the same fire door principles apply to all of them.
We check that each door in your Portishead 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 Portishead we replace them with the type and size the certification specifies.
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:
- Brush or blade smoke seals
- Identification of the specified seals
- Check of gaps and closing after fitting
- Removal of damaged or painted seals
The regulations behind fire doors in Portishead
The rules that apply to fire doors in Portishead 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 Portishead 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
Is Portishead within your coverage area?
It is. We cover Portishead in Somerset and neighbouring towns such as Nailsea. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
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.
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.
