Cavity wall suitability survey for Christchurch properties
If your property is in Christchurch or the BH6 district or nearby Bournemouth and Poole, it is within our Dorset coverage. It is roughly 4 miles east of Bournemouth.
Buyers and sellers in Christchurch often book this check when a survey report or EPC raises questions about the walls. A survey in Christchurch gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Exposure matters for every cavity wall. Dorset 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, in Christchurch filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

What the surveyor checks
Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
