Damp investigation after cavity insulation for Doncaster properties
We cover Doncaster and the DN1 postcode district, including nearby Rotherham, Chapeltown and Barnsley. It is roughly 17 miles north-east of Sheffield.
If your Doncaster installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Doncaster 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.
Exposure matters for every cavity wall. South Yorkshire 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.
For regulations, if cavity wall insulation follows in Doncaster, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
