Existing insulation and guarantee check for Farnborough properties
Farnborough sits in Hampshire, about 39 miles north-east of Southampton. We work across the GU14 district, including nearby Aldershot, Fleet and Yateley.
Buyers and sellers in Farnborough often book this check when a survey report or EPC raises questions about the walls. A survey in Farnborough gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Before any material is chosen, exposure is checked. Hampshire 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 Farnborough, 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.
