Loft insulation for Harwich properties

We cover Harwich and the CO12 postcode district, including nearby Clacton-on-Sea and Colchester. It is roughly 37 miles north-east of Chelmsford.

We check ventilation as carefully as insulation in Harwich homes, because both matter for keeping a house dry. Where a Harwich home also has empty cavity walls, we can survey those at the same time.

On compliance, if cavity wall insulation follows in Harwich, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
