Damp investigation after cavity insulation for Chippenham properties

Chippenham is among the towns we cover in Wiltshire, alongside Trowbridge and Swindon. It is about 16 miles south-west of Swindon.

If your Chippenham installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Chippenham properties, so you can choose who fixes them.

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 the rules side, if cavity wall insulation follows in Chippenham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
