Intumescent strips and smoke seals in Thornaby-on-Tees, done to the evidence
When you book intumescent strips and smoke seals in Thornaby-on-Tees, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
In and around Thornaby-on-Tees, fire door work covers everything from care homes to small blocks of flats. We plan each job around the people who use the building.
Painted and missing seals are among the most common fire door defects nationally; in Thornaby-on-Tees we replace them with the type and size the certification specifies. We check that each door in your Thornaby-on-Tees 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:
- Intumescent pads to hinges and locks
- Brush or blade smoke seals
- Check of gaps and closing after fitting
- Intumescent strips in frame or leaf edge

Common questions
Do you cover TS17 and nearby postcodes?
Yes. We cover Thornaby-on-Tees including TS17, and nearby towns such as Stockton-on-Tees and Billingham. The survey and written quote are free.
Can you work from an existing inspection report for my Thornaby-on-Tees 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.
