Common questions in Harpenden

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.

Which fire safety law applies in Harpenden?

Can you price remedial work in Harpenden from another company's report?

Yes. Send the report and we will price each line for your building in Harpenden, or revisit specific doors if the report lacks detail.

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.
