Questions from Hounslow clients

Does regulation 10 apply to buildings in Hounslow?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Hounslow is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those 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 quickly can you inspect fire doors in Hounslow?

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.

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.
