Cavity cleaning and debris removal for New Milton properties

Our Hampshire coverage takes in New Milton (BH25) and nearby Hythe, Totton and Southampton. It is around 16 miles south-west of Southampton.

Where a New Milton 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. Damp in an insulated New Milton home is not always the insulation's fault, so the diagnosis comes before any extraction.

Local weather affects which walls can be filled. Hampshire 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 New Milton, 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.

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.
