Glazed fire doors: our service in Harrow
If you need glazed fire doors 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 care homes to hotels. We plan each job around the people who use the building.
When a vision panel breaks in a Harrow building, we re-glaze it to the door's original glazing system rather than a near match. We check glazed doors in Harrow for both fire performance and safety glazing before recommending repair or replacement.
Why glazing is a common failure point
Vision panels are useful on corridors, classrooms and wards, but they are also where many fire doors go wrong. Ordinary glass gets swapped in after a breakage, beads are fixed with the wrong pins, glazing seals are missing, or an aperture has been cut on site with no evidence behind it. Each of these can undermine the whole door. Our fire door glazing guide covers the details.
What you get:
- Re-glazing of damaged vision panels to the original system
- Evidence of the glazing system fitted
- Tested beads, glazing seals and fixings
- Glazed doorsets with certified apertures
Which fire door rules apply in Harrow?
The rules that apply to fire doors in Harrow 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. Enforcement of fire safety law in Harrow sits with the London Fire Brigade.
Where a Harrow 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.

Common questions
Do you work in Harrow?
Yes, we take on glazed fire doors in Harrow and the surrounding area, including Wembley and Northolt. Send your postcode and a few details and we'll come back with survey dates.
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.
Are wired glass fire doors still acceptable?
Some older doors use wired glass. Whether it is acceptable depends on its fire rating and whether it meets safety glazing rules for that location. We advise case by case.
Can any toughened glass go in a fire door?
No. Fire doors need fire-rated glass of the type and size covered by the door's test evidence, fitted with the matching beads and seals. Standard toughened glass is not fire resisting.
