Existing insulation and guarantee check for Kendal properties

Kendal sits in Cumbria, about 40 miles south of Carlisle. We work across the LA9 district, including nearby Penrith and Barrow in Furness.

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

Local weather affects which walls can be filled. Parts of Cumbria face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

As for paperwork, if cavity wall insulation follows in Kendal, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

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.
