Damp investigation after cavity insulation for Staines properties
We cover Staines and the TW18 postcode district, including nearby Egham, Sunbury-on-Thames and Walton-on-Thames. It is about 14 miles north of Guildford.
If your Staines installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Staines wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.
Wind-driven rain is the first thing the surveyor weighs up. Much of Surrey 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.
On compliance, if cavity wall insulation follows in Staines, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
