Existing insulation and guarantee check for East Grinstead properties

East Grinstead is among the towns we cover in West Sussex, alongside Crawley, Haywards Heath and Burgess Hill. It is roughly 7 miles east of Crawley.

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

Wind-driven rain is the first thing the surveyor weighs up. 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.

On compliance, if cavity wall insulation follows in East Grinstead, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
