Existing insulation and guarantee check for Bishop Auckland properties
If your property is in Bishop Auckland or the DL14 district or nearby Newton Aycliffe, Durham and Darlington, it is within our County Durham coverage. It is roughly 9 miles south-west of Durham.
Buyers and sellers in Bishop Auckland often book this check when a survey report or EPC raises questions about the walls. A survey in Bishop Auckland gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Every elevation is judged on its own exposure. County Durham 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 compliance, if cavity wall insulation follows in Bishop Auckland, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

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.
