Getting glazed fire doors right in Harpenden
We provide glazed fire doors in Harpenden (AL5 and the surrounding postcodes), from the first survey through to a documented handover.
Around Harpenden, schools, small blocks of flats and light industrial buildings all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
When a vision panel breaks in a Harpenden building, we re-glaze it to the door's original glazing system rather than a near match. We check glazed doors in Harpenden for both fire performance and safety glazing before recommending repair or replacement.
New glazed doors or re-glazing?
Where a door already has a certified aperture, it can usually be re-glazed with the specified glass and system after damage. Cutting a new vision panel into an existing fire door is a different matter: it is only acceptable if the door's certification covers that aperture size and position. In most cases a new glazed doorset is the right answer.
Each installation includes:
- Re-glazing of damaged vision panels to the original system
- Fire-rated glass suited to the rating and location
- Evidence of the glazing system fitted
- Tested beads, glazing seals and fixings
Rules and responsibilities in Harpenden
In Harpenden, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Harpenden building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.

Common questions
Is Harpenden within your coverage area?
It is. We cover Harpenden in Hertfordshire and neighbouring towns such as St Albans. There is no charge for the survey.
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.
What happens if the glass in a fire door breaks?
It should be re-glazed with the same fire-rated glass and glazing system as the original. A temporary board or standard glass leaves the door non-compliant.
