Cavity wall suitability survey for Sutton properties

Sutton is among the towns we cover in Greater London, alongside Carshalton, Wallington and Coulsdon. It is about 11 miles south of London.

The written result for your Sutton property is plain English: what we found, what it means and what, if anything, to do next. A survey in Sutton gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Wind-driven rain is the first thing the surveyor weighs up. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

For regulations, in Sutton 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.

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.
