Existing insulation and guarantee check for Worthing properties
Worthing sits in West Sussex, about 22 miles south of Crawley. We work across the BN11 district, including nearby Littlehampton, Bognor Regis and Burgess Hill.
The written result for your Worthing property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Worthing is photographed and logged, so you have a record to show a buyer, lender or contractor.
Every elevation is judged on its own exposure. West Sussex 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.
In terms of approvals, if cavity wall insulation follows in Worthing, 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.
