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 Prescot.

Questions from Prescot clients

Which fire safety law applies in Prescot?

Prescot 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.

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 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.

Yes. As well as Prescot itself we cover nearby towns including Huyton, St Helens and Halewood.
