Intumescent strips and smoke seals in Harrow, done to the evidence
If you need intumescent strips and smoke seals in Harrow, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
In and around Harrow, fire door work covers everything from converted flats to shared houses. We plan each job around the people who use the building.
We check that each door in your Harrow building closes and latches against its new seals before signing it off. Painted and missing seals are among the most common fire door defects nationally; in Harrow we replace them with the type and size the certification specifies.
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.
What you get:
- Check of gaps and closing after fitting
- Removal of damaged or painted seals
- Intumescent pads to hinges and locks
- Identification of the specified seals
Fire door law for Harrow properties
Fire doors in Harrow fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. 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. In London, the London Fire Brigade is the enforcing authority for fire safety law.
For residential buildings in Harrow above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. 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.
Buildings and duty holders in Harrow
Typical settings for intumescent strips and smoke seals include HMOs, schools and blocks of flats. In Harrow, as anywhere, the duty holder varies: a responsible person for a workplace, a landlord or managing agent for a block or HMO, or a homeowner after building work. We adjust access, timing and paperwork to suit whoever commissions the work.

Common questions
Do you cover HA1 and nearby postcodes?
Yes. We cover Harrow including HA1, and nearby towns such as Wembley and Northolt. The survey and written quote are free.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
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.
