Common questions in Derby

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 Derby?

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.

Does regulation 10 apply to buildings in Derby?

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