Fire Door Gap Adjustment in Gainsborough

Whether it is a block of flats, a school or a care home in Gainsborough, our fire door gap adjustments follow the same door-by-door method and report format.

Fire door gap adjustment is the work needed to bring the gaps between a fire door leaf and its frame, and under the door, back within the tolerance in the door's evidence, typically 2 to 4 mm around the edges. We use the same method for buildings in Gainsborough.

Questions from Gainsborough clients

Which fire safety law applies in Gainsborough?

Gainsborough is in England, so the Regulatory Reform (Fire Safety) Order 2005 applies, together with the Fire Safety (England) Regulations 2022 for multi-occupied residential buildings.

Why do gaps open up over time?

Hinges wear and drop, frames shrink or move, leaves warp, and doors are sometimes planed after flooring changes. Each needs a different repair.

What gap is allowed around a fire door?

Most guidance and manufacturers' evidence expect gaps of about 2 to 4 mm at the head and edges, with 3 mm as a practical target. The door's own certification or test evidence takes precedence if it states a different figure.

How quickly can you inspect fire doors in Gainsborough?

It depends on the number of doors and access. Tell us what you need and we will give you the earliest date when you call, and confirm it in writing.
