Double fire doors: our service in Gainsborough
Looking for double fire doors in Gainsborough? We supply and fit certified fire doors and components across Gainsborough and the wider Lincolnshire area, working from a free survey and a fixed written quote.
Gainsborough has a broad mix of buildings, including family homes after loft conversions, light industrial buildings and small blocks of flats, and the same fire door principles apply to all of them.
Every pair we fit in Gainsborough is commissioned so both leaves close in the right order and latch. Leaf-and-a-half doors are a practical option for Gainsborough 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.
Each installation includes:
- Commissioning of closing sequence
- Meeting-stile intumescent and smoke seals
- Closers matched to each leaf
- Door coordinators where meeting edges are rebated
The regulations behind fire doors in Gainsborough
The rules that apply to fire doors in Gainsborough 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.
Where a Gainsborough 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
Is Gainsborough within your coverage area?
It is. We cover Gainsborough in Lincolnshire and neighbouring towns such as Retford. 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.
Can double fire doors be held open?
Yes, with hold-open devices that release on the fire alarm, or with free-swing closers. Wedges and hooks are not acceptable.
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.
