What intumescent strips and smoke seals in Preston should include
Our intumescent strips and smoke seals service in Preston is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Fire doors in Preston protect escape routes in clinics, purpose-built blocks of flats and mixed-use office buildings 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 Preston we replace them with the type and size the certification specifies. Seal replacement in Preston can be combined with any other remedials on the same inspection report.
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.
What you get:
- Brush or blade smoke seals
- Intumescent strips in frame or leaf edge
- Removal of damaged or painted seals
- Check of gaps and closing after fitting
What the rules say for Preston
In Preston, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Preston building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.
Which buildings in Preston need intumescent strips and smoke seals?
The need for intumescent strips and smoke seals usually arises in care homes or blocks of flats, and sometimes offices. Each has its own pressures, such as residents at home or a building that must stay open, so we plan the sequence of work in Preston to keep escape routes protected throughout.

Questions from Preston
Is Preston within your coverage area?
It is. We cover Preston in Lancashire and neighbouring towns such as Leyland. There is no charge for the survey.
Can you work from an existing inspection report for my Preston 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.
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 smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
