We cover Stratford-upon-Avon and the CV37 postcode district, including nearby Warwick, Leamington Spa and Kenilworth. It is roughly 8 miles south-west of Warwick.
The written result for your Stratford-upon-Avon property is plain English: what we found, what it means and what, if anything, to do next. Buyers and sellers in Stratford-upon-Avon often book this check when a survey report or EPC raises questions about the walls.
Wind-driven rain is the first thing the surveyor weighs up. Much of Warwickshire 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.
On compliance, if cavity wall insulation follows in Stratford-upon-Avon, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation
Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
