Getting intumescent strips and smoke seals right in Hatfield
When you book intumescent strips and smoke seals in Hatfield, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
In and around Hatfield, fire door work covers everything from family homes after loft conversions to light industrial buildings. 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 Hatfield we replace them with the type and size the certification specifies. Seal replacement in Hatfield can be combined with any other remedials on the same inspection report.
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.
As standard, the work covers:
- Brush or blade smoke seals
- Identification of the specified seals
- Check of gaps and closing after fitting
- Removal of damaged or painted seals

Questions
Do you work in Hatfield?
Yes, we take on intumescent strips and smoke seals in Hatfield and the surrounding area, including Welwyn Garden City and St Albans. Send your postcode and a few details and we'll come back with survey dates.
What happens on a survey in Hatfield?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
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 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.
