Cavity wall insulation removal for Folkestone properties

Folkestone is among the towns we cover in Kent, alongside Dover, Ashford and Deal. It is roughly 31 miles south-east of Maidstone.

Where a Folkestone 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. If your Folkestone installation has a guarantee, we check it first; the guarantee route may cover the work.

Local weather affects which walls can be filled. Much of Kent 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, if cavity wall insulation follows in Folkestone, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Should I remove my cavity wall insulation?

Not always. Welsh Government guidance makes the point that extraction is not always the right remedy. Damp can come from blocked gutters, failed pointing, bridged damp-proof courses or condensation, none of which removal fixes. We start with a damp investigation and borescope checks, then recommend removal only where the fill itself is the problem.
