Getting intumescent strips and smoke seals right in Gainsborough
When you book intumescent strips and smoke seals in Gainsborough, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
In and around Gainsborough, fire door work covers everything from small blocks of flats to schools. 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 Gainsborough we replace them with the type and size the certification specifies. We check that each door in your Gainsborough building closes and latches against its new seals before signing it off.
Getting the specification right
The door's certification states the type, size and position of strips and seals: in the frame or the leaf edge, single or double, and whether a combined intumescent and smoke seal is used. Replacements must match. Swapping in a generic strip from a hardware shop can undermine the door's performance.
Each installation includes:
- Intumescent strips in frame or leaf edge
- Brush or blade smoke seals
- Intumescent pads to hinges and locks
- Removal of damaged or painted seals

In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.

Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Questions
Do you work in Gainsborough?
Yes, we take on intumescent strips and smoke seals in Gainsborough and the surrounding area, including Retford and Scunthorpe. Send your postcode and a few details and we'll come back with survey dates.
What happens on a survey in Gainsborough?
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
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.
