Existing insulation and guarantee check for Hexham properties

We cover Hexham and the NE46 postcode district, including nearby Morpeth and Cramlington. It is roughly 25 miles south-west of Blyth.

Every inspection point in Hexham is photographed and logged, so you have a record to show a buyer, lender or contractor. Buyers and sellers in Hexham often book this check when a survey report or EPC raises questions about the walls.

Every elevation is judged on its own exposure. Northumberland 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.

On the rules side, if cavity wall insulation follows in Hexham, 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.
