Existing insulation and guarantee check for Northwich properties
If your property is in Northwich or the CW9 district or nearby Winsford, Warrington and Runcorn, it is within our Cheshire coverage. It is roughly 16 miles east of Chester.
Buyers and sellers in Northwich often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Northwich is photographed and logged, so you have a record to show a buyer, lender or contractor.
Local weather affects which walls can be filled. Cheshire 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 Northwich, 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.
