Draught-proofing in Horsham

From the first survey to the paperwork, draught-proofing in Horsham is handled by one team and one contract. 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 Horsham properties

We cover Horsham and the RH12 postcode district, including nearby Crawley, Haywards Heath and Burgess Hill. It is roughly 7 miles south-west of Crawley.

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

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