Questions from Durham clients

Do you cover the area around Durham?

Yes. As well as Durham itself we cover nearby towns including Chester-le-Street, Houghton-Le-Spring and Stanley.

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.

Can you fix a big gap with a thicker intumescent strip?

Not as a general rule. Seals are tested for a particular gap; using oversized seals to hide a poor fit is not a reliable repair.

Which fire safety law applies in Durham?

Durham 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.
