Existing insulation and guarantee check for Plymstock properties

Our Devon coverage takes in Plymstock (PL9) and nearby Plymouth, Paignton and Newton Abbot. It is around 35 miles south-west of Exeter.

Buyers and sellers in Plymstock often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Plymstock is photographed and logged, so you have a record to show a buyer, lender or contractor.

Local weather affects which walls can be filled. Parts of Devon 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 Plymstock, 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.
