Damp investigation after cavity insulation for Trowbridge properties
We cover Trowbridge and the BA14 postcode district, including nearby Chippenham, Swindon and Salisbury. It is about 25 miles south-west of Swindon.
We never cold-call in Trowbridge or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated Trowbridge home is not always the insulation's fault, so the diagnosis comes before any extraction.
Wind-driven rain is the first thing the surveyor weighs up. Wiltshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
On compliance, if cavity wall insulation follows in Trowbridge, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
