Existing insulation and guarantee check for Nailsea properties
Our Somerset coverage takes in Nailsea (BS48) and nearby Portishead, Clevedon and Weston-super-Mare. It is around 32 miles north-east of Taunton.
A survey in Nailsea gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Nailsea wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.
Wind-driven rain is the first thing the surveyor weighs up. Somerset 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.
On the rules side, if cavity wall insulation follows in Nailsea, 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.
