Common questions in Welwyn Garden City

Why do gaps open up over time?

Hinges wear and drop, frames shrink or move, leaves warp, and doors are sometimes planed after flooring changes. Each needs a different repair.

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.

Does regulation 10 apply to buildings in Welwyn Garden City?

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

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