Cavity wall insulation removal for Weymouth properties
If your property is in Weymouth or the DT4 district or nearby Poole, Bournemouth and Christchurch, it is within our Dorset coverage. It is roughly 27 miles west of Bournemouth.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Weymouth properties, so you can choose who fixes them. Where a Weymouth wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.
Wind-driven rain is the first thing the surveyor weighs up. 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, if cavity wall insulation follows in Weymouth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

Should I remove my cavity wall insulation?
Not always. Welsh Government guidance makes the point that extraction is not always the right remedy. Damp can come from blocked gutters, failed pointing, bridged damp-proof courses or condensation, none of which removal fixes. We start with a damp investigation and borescope checks, then recommend removal only where the fill itself is the problem.
