Existing insulation and guarantee check for Chester properties

Chester is among the towns we cover in Cheshire, alongside Ellesmere Port Town, Runcorn and Widnes. Chester is one of the main towns we cover in Cheshire.

Where a Chester wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Buyers and sellers in Chester often book this check when a survey report or EPC raises questions about the walls.

Every elevation is judged on its own exposure. 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.

As for paperwork, if cavity wall insulation follows in Chester, 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.
