Cavity wall suitability survey for Derby properties
If your property is in Derby or the DE1 district or nearby Belper, Ilkeston and Heanor, it is within our Derbyshire coverage. Derby is one of the main towns we cover in Derbyshire.
The written result for your Derby property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Derby 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. Derbyshire 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, in Derby 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.

What the surveyor checks
Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.
