Fire Door Gap Adjustment in Chesterfield: questions

Does regulation 10 apply to buildings in Chesterfield?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Chesterfield is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those buildings.

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.

How quickly can you inspect fire doors in Chesterfield?

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.

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.
