Fire Stopping Around Doors in Gainsborough

We provide fire stopping works for buildings in Gainsborough and the DN21 postcode district, from single doors to whole blocks and estates.

In short: fire stopping is the sealing of gaps and openings in fire-resisting walls and floors so fire and smoke cannot pass through. Around a fire door it mainly means the gap between the door frame and the wall, which must be sealed as well as the door itself.

Common questions in Gainsborough

Does regulation 10 apply to buildings in Gainsborough?

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

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

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

Do you need to remove architraves?

Often, yes. The frame gap is usually hidden behind the architrave, so we remove and refit it to inspect and seal properly.

Is expanding foam acceptable around a fire door frame?

Only a fire-rated foam with evidence for that use and gap size. Ordinary expanding foam is not suitable. BS 8214:2026 lists acceptable approaches such as suitable mastics, foams and stone wool.
