Cavity cleaning and debris removal for Falmouth properties
Our Cornwall coverage takes in Falmouth (TR11) and nearby Truro, Redruth and Camborne. It is about 7 miles south of Truro.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Falmouth properties, so you can choose who fixes them. Damp in an insulated Falmouth home is not always the insulation's fault, so the diagnosis comes before any extraction.
Before any material is chosen, exposure is checked. Parts of Cornwall face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
For regulations, if cavity wall insulation follows in Falmouth, 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.
