Intumescent strips and smoke seals for Stevenage buildings
Our intumescent strips and smoke seals service in Stevenage is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Buildings in and around Stevenage range from low-rise blocks of flats to care homes and industrial estates. 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 Stevenage we replace them with the type and size the certification specifies. We check that each door in your Stevenage building closes and latches against its new seals before signing it off.
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.
On a typical job that means:
- Intumescent strips in frame or leaf edge
- Check of gaps and closing after fitting
- Identification of the specified seals
- Brush or blade smoke seals
Fire door law for Stevenage properties
The rules that apply to fire doors in Stevenage are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts.
Where a Stevenage block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

The need for intumescent strips and smoke seals usually arises in offices or blocks of flats, and sometimes care homes. Each has its own pressures, such as residents at home or a building that must stay open, so we plan the sequence of work in Stevenage to keep escape routes protected throughout.

Common questions
Is Stevenage within your coverage area?
It is. We cover Stevenage in Hertfordshire and neighbouring towns such as Hitchin. There is no charge for the survey.
How quickly can you survey in Stevenage?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
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.
