Intumescent strips and smoke seals in Durham, done to the evidence
From the DH1 postcode district outwards, we take on intumescent strips and smoke seals across Durham for homes, blocks and workplaces.
Around Durham, care homes, family homes after loft conversions and small blocks of flats all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
Painted and missing seals are among the most common fire door defects nationally; in Durham we replace them with the type and size the certification specifies. Seal replacement in Durham can be combined with any other remedials on the same inspection report.
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.
What you get:
- Identification of the specified seals
- Removal of damaged or painted seals
- Check of gaps and closing after fitting
- Brush or blade smoke seals
Rules and responsibilities in Durham
England's framework applies in Durham. 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 Durham, 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 Durham need intumescent strips and smoke seals?
From HMOs to schools, the requirement for intumescent strips and smoke seals in Durham 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
Do you cover DH1 and nearby postcodes?
Yes. We cover Durham including DH1, and nearby towns such as Chester-le-Street and Houghton-Le-Spring. The survey and written quote are free.
Can you work from an existing inspection report for my Durham 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.
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.
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.
