Fire Door Gap Adjustment in Darlington

From the DL1 district outwards, we cover Darlington and neighbouring towns such as Newton Aycliffe and Stockton-on-Tees for fire door gap adjustments.

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 Darlington.

Fire Door Gap Adjustment in Darlington: questions

Do you work in occupied buildings in Darlington?

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

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 Darlington?

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