Draught-proofing in Northolt

Draught-proofing in Northolt starts with a free survey of the property, then a written result and a fixed price before any work is booked. Draught-proofing seals the gaps that let warm air out and cold air in, around doors, windows, letterboxes, loft hatches and skirting boards, while leaving planned ventilation alone.

Draught-proofing for Northolt properties

Our Greater London coverage takes in Northolt (UB5) and nearby Greenford, Harrow and Southall. It is roughly 11 miles west of London.

Small measures like this are often among the cheapest per pound saved, and they suit Northolt homes of every age. In Northolt homes this is often done on the same visit as a cavity fill, which saves a second trip.

As for paperwork, if cavity wall insulation follows in Northolt, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
