Damp investigation after cavity insulation in Halewood

Damp investigation after cavity insulation for Halewood properties

Our Merseyside coverage takes in Halewood (L26) and nearby Huyton, Prescot and Liverpool. It is roughly 7 miles south-east of Liverpool.

Where a Halewood 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. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Halewood properties, so you can choose who fixes them.

Local weather affects which walls can be filled. 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 Halewood, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England
