Intumescent strips and smoke seals in Runcorn: what's involved
We provide intumescent strips and smoke seals in Runcorn (WA7 and the surrounding postcodes), from the first survey through to a documented handover.
Fire doors in Runcorn protect escape routes in high-street shops, low-rise blocks of flats 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 Runcorn we replace them with the type and size the certification specifies. We check that each door in your Runcorn 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:
- Intumescent strips in frame or leaf edge
- Brush or blade smoke seals
- Check of gaps and closing after fitting
- Intumescent pads to hinges and locks
Which fire door rules apply in Runcorn?
Fire doors in Runcorn 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 Runcorn 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.
Which buildings in Runcorn need intumescent strips and smoke seals?
From HMOs to blocks of flats, the requirement for intumescent strips and smoke seals in Runcorn comes from the fire strategy or risk assessment for the building. We work from that document, or help you interpret your inspection report, before quoting.

Questions from Runcorn
Do you cover WA7 and nearby postcodes?
Yes. We cover Runcorn including WA7, and nearby towns such as Widnes and Halewood. The survey and written quote are free.
What happens on a survey in Runcorn?
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.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
