Cavity cleaning and debris removal for Coulsdon properties
We cover Coulsdon and the CR5 postcode district, including nearby Purley, Wallington and Sutton. It is about 13 miles south of London.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Coulsdon properties, so you can choose who fixes them. Where a Coulsdon 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.
Every elevation is judged on its own exposure. Much of Greater London 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.
On the rules side, if cavity wall insulation follows in Coulsdon, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
