Fire Door Gap Adjustment in Grimsby

From the DN32 district outwards, we cover Grimsby and neighbouring towns such as Cleethorpes and Kingston upon Hull for fire door gap adjustments.

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 Grimsby.

Grimsby FAQs

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.

Which fire safety law applies in Grimsby?

Grimsby 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.

How big can the gap under a fire door be?

It depends on the door's evidence. Doors without smoke control often allow a larger threshold gap, sometimes up to around 8 to 10 mm, while smoke control doors usually need 3 mm or less or a tested drop seal.

Can you price remedial work in Grimsby from another company's report?

Yes. Send the report and we will price each line for your building in Grimsby, or revisit specific doors if the report lacks detail.
