Cavity cleaning and debris removal for Chatham properties

Chatham sits in Kent, roughly 8 miles north of Maidstone. We work across the ME4 district, including nearby Gillingham, Rochester and Strood.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Chatham properties, so you can choose who fixes them. If your Chatham installation has a guarantee, we check it first; the guarantee route may cover the work.

Local weather affects which walls can be filled. Much of Kent 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 Chatham, 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.
