Cavity cleaning and debris removal for Heswall properties
If your property is in Heswall or the CH60 district or nearby Bebington, Birkenhead and Wallasey, it is within our Merseyside coverage. It is around 7 miles south-west of Liverpool.
Damp in an insulated Heswall home is not always the insulation's fault, so the diagnosis comes before any extraction. If your Heswall installation has a guarantee, we check it first; the guarantee route may cover the work.
Before any material is chosen, exposure is checked. Merseyside 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.
In terms of approvals, if cavity wall insulation follows in Heswall, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

Why debris matters
A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
