Double fire doors in Dartford: what's involved
We provide double fire doors in Dartford (DA1 and the surrounding postcodes), from the first survey through to a documented handover.
Dartford has a broad mix of buildings, including care homes, industrial estates and HMOs, and the same fire door principles apply to all of them.
Double doors on wards, school corridors and lobbies in Dartford take heavy use, so closing sequence and meeting-edge seals get extra attention. Leaf-and-a-half doors are a practical option for Dartford care homes and schools that need occasional wide access.
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:
- Door coordinators where meeting edges are rebated
- Closers matched to each leaf
- Equal pair or leaf-and-a-half doorsets
- Meeting-stile intumescent and smoke seals
Rules and responsibilities in Dartford
In Dartford, 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 Dartford 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.
Who needs double fire doors in Dartford?
From office cores to care homes, the requirement for double fire doors in Dartford comes from the fire strategy or risk assessment for the building. We work from that document, or help you interpret your inspection report, before quoting.

Questions
Do you work in Dartford?
Yes, we take on double fire doors in Dartford and the surrounding area, including Bexley and Swanley. Send your postcode and a few details and we'll come back with survey dates.
Can you work from an existing inspection report for my Dartford 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.
Do both leaves need closers?
Usually, yes. Each leaf of a fire door pair needs to close itself. The closers are sized to each leaf's width and weight.
