Questions from Portsmouth clients

Which fire safety law applies in Portsmouth?

Portsmouth 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.

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.

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.

Do you cover the area around Portsmouth?

Yes. As well as Portsmouth itself we cover nearby towns including Gosport, Fareham and Ryde.
