Cavity cleaning and debris removal for Thatcham properties
Thatcham sits in Berkshire, about 13 miles west of Reading. We work across the RG19 district, including nearby Newbury, Reading and Lower Earley.
Damp in an insulated Thatcham home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Thatcham 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.
Before any material is chosen, exposure is checked. Much of Berkshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
As for paperwork, if cavity wall insulation follows in Thatcham, 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.
