Intumescent strips and smoke seals: our service in Doncaster
From the DN1 postcode district outwards, we take on intumescent strips and smoke seals across Doncaster for homes, blocks and workplaces.
Buildings in and around Doncaster range from care homes to GP surgeries and HMOs. 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 Doncaster we replace them with the type and size the certification specifies. We check that each door in your Doncaster building closes and latches against its new seals before signing it off.
Pads, linings and hidden protection
Fire doors also rely on intumescent material you cannot see: pads behind hinges, linings around lock bodies and glazing seals. Where these are missing or damaged, we fit the correct items as part of the work.
On a typical job that means:
- Identification of the specified seals
- Brush or blade smoke seals
- Removal of damaged or painted seals
- Check of gaps and closing after fitting
Which fire door rules apply in Doncaster?
England's framework applies in Doncaster. 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 Doncaster, 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.
Which buildings in Doncaster need intumescent strips and smoke seals?
Landlords, managing agents, facilities teams and homeowners in Doncaster can all commission intumescent strips and smoke seals from us. The usual settings are schools and blocks of flats, though single doors for care homes are just as welcome.

Common questions
Do you cover DN1 and nearby postcodes?
Yes. We cover Doncaster including DN1, and nearby towns such as Bentley and Rotherham. The survey and written quote are free.
Can you work from an existing inspection report for my Doncaster 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.
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.
