Stevenage FAQs

Does regulation 10 apply to buildings in Stevenage?

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

Do you cover the area around Stevenage?

Yes. As well as Stevenage itself we cover nearby towns including Hitchin, Letchworth Garden City and Welwyn Garden City.
