Existing insulation and guarantee check for Swindon properties

Our Wiltshire coverage takes in Swindon (SN1) and nearby Chippenham and Trowbridge. Swindon is one of the main towns we cover in Wiltshire.

Every inspection point in Swindon is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Swindon gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Exposure matters for every cavity wall. Wiltshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

For regulations, if cavity wall insulation follows in Swindon, 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.
