Cavity cleaning and debris removal across Northamptonshire
We cover 7 towns in Northamptonshire, including Northampton, Corby, Kettering, Wellingborough, Rushden and more.
Exposure matters for every cavity wall. Much of Northamptonshire 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.
Damp in an insulated Northamptonshire home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Northamptonshire 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.
Building Regulations in England
Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

Why debris matters
A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
