Wall tie replacement for St Austell properties
Our Cornwall coverage takes in St Austell (PL25) and nearby Bodmin, Truro and Newquay. It is around 14 miles north-east of Truro.
Damp in an insulated St Austell home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a St Austell 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.
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.
On compliance, if cavity wall insulation follows in St Austell, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Signs of wall tie failure
Horizontal cracks in mortar joints at regular vertical intervals, bulging brickwork, or lifting of the roof verge. Older galvanised ties, especially in walls built before the 1980s, are the usual suspects.
