Getting double fire doors right in Harpenden
Our double fire doors service in Harpenden is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
In and around Harpenden, fire door work covers everything from family homes after loft conversions to schools. We plan each job around the people who use the building.
Leaf-and-a-half doors are a practical option for Harpenden care homes and schools that need occasional wide access. Double doors on wards, school corridors and lobbies in Harpenden take heavy use, so closing sequence and meeting-edge seals get extra attention.
Why pairs need extra care
The meeting stiles are the weak point of a pair. Gaps there must be controlled, both leaves need intumescent and smoke seals as specified, and if the meeting edges are rebated, a door coordinator is usually needed so the leaves close in the right order. If they close out of sequence, the door may not latch and will not perform as tested.
On a typical job that means:
- Commissioning of closing sequence
- Meeting-stile intumescent and smoke seals
- Closers matched to each leaf
- Equal pair or leaf-and-a-half doorsets

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.
Can you work from an existing inspection report for my Harpenden building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
What does a door coordinator do?
It holds the leaf that must close second until the first leaf has shut, so rebated meeting edges close in the right order and both leaves latch. Without it, the pair can end up open or misaligned.
Why does the gap between the two leaves matter?
The meeting edges are where flame and smoke can pass most easily. The gap and the seals there must match the certification for the pair to perform as tested.
