Fire Door Gap Adjustment in Chesham

We provide fire door gap adjustments for buildings in Chesham and the HP5 postcode district, from single doors to whole blocks and estates.

Fire door gap adjustment is the work needed to bring the gaps between a fire door leaf and its frame, and under the door, back within the tolerance in the door's evidence, typically 2 to 4 mm around the edges. We use the same method for buildings in Chesham.

Fire Door Gap Adjustment in Chesham: questions

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.

Does regulation 10 apply to buildings in Chesham?

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

Do you work in occupied buildings in Chesham?

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

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.
