Existing insulation and guarantee check for Great Malvern properties

Our Worcestershire coverage takes in Great Malvern (WR14) and nearby Worcester, Droitwich and Stourport-on-Severn. It is around 7 miles south-west of Worcester.

Where a Great Malvern wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. The written result for your Great Malvern property is plain English: what we found, what it means and what, if anything, to do next.

Local weather affects which walls can be filled. Worcestershire 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 Great Malvern, 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.
