What intumescent strips and smoke seals in Blackburn should include
If you need intumescent strips and smoke seals in Blackburn, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
Buildings in and around Blackburn range from schools to offices and GP surgeries. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Painted and missing seals are among the most common fire door defects nationally; in Blackburn we replace them with the type and size the certification specifies. We check that each door in your Blackburn building closes and latches against its new seals before signing it off.
Why seals fail
Seals are the most common defect on fire door inspections. They get painted over, pulled out, damaged by cleaning or simply worn by years of use. A painted brush seal no longer seals, and a strip of the wrong size may not close the gap in a fire. Our guide to seals explains the different types.
What you get:
- Check of gaps and closing after fitting
- Brush or blade smoke seals
- Intumescent pads to hinges and locks
- Identification of the specified seals
What the rules say for Blackburn
England's framework applies in Blackburn. 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 Blackburn, 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.

It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.

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.
