Intumescent strips and smoke seals: our service in St Helens
Our intumescent strips and smoke seals service in St Helens is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Fire doors in St Helens protect escape routes in care homes, offices and schools 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 St Helens we replace them with the type and size the certification specifies. We check that each door in your St Helens 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:
- Intumescent pads to hinges and locks
- Check of gaps and closing after fitting
- Brush or blade smoke seals
- Removal of damaged or painted seals
Fire door law for St Helens properties
England's framework applies in St Helens. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in St Helens, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.

Common questions
Is St Helens within your coverage area?
It is. We cover St Helens in Merseyside and neighbouring towns such as Prescot. There is no charge for the survey.
How quickly can you survey in St Helens?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
