Commercial cavity wall insulation for St Austell properties
We cover St Austell and the PL25 postcode district, including nearby Bodmin, Truro and Newquay. It is about 14 miles north-east of Truro.
For landlords and managing agents in St Austell, we survey in batches and return a result sheet and fixed price per address. Work on St Austell rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer.
Wind-driven rain is the first thing the surveyor weighs up. 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.
In terms of approvals, in St Austell filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What is different on commercial jobs
Access is planned around opening hours, often with towers or MEWPs. Material choice takes account of building use and fire requirements, so non-combustible mineral wool is often specified. Work is usually standard-rated for VAT unless the building qualifies for a relief, which we confirm on the quote.
