Fire Door Gap Adjustment in Sunbury-on-Thames: questions

Do you work in occupied buildings in Sunbury-on-Thames?

Yes. Inspections and repairs in Sunbury-on-Thames can be carried out in occupied flats, schools, care homes and workplaces, with doors kept closable at all times.

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.

Does regulation 10 apply to buildings in Sunbury-on-Thames?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Sunbury-on-Thames 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.
