Common questions in Trowbridge

How quickly can you inspect fire doors in Trowbridge?

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.

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.

Which fire safety law applies in Trowbridge?

Trowbridge is in England, so the Regulatory Reform (Fire Safety) Order 2005 applies, together with the Fire Safety (England) Regulations 2022 for multi-occupied residential 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.
