Damp investigation after cavity insulation for Bodmin properties
If your property is in Bodmin or the PL31 district or nearby St Austell, Newquay and Truro, it is within our Cornwall coverage. It is about 20 miles north-east of Truro.
Where a Bodmin 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 Bodmin home is not always the insulation's fault, so the diagnosis comes before any extraction.
Local weather affects which walls can be filled. 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 Bodmin, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Common causes we check
Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
