Remove and refill across Northamptonshire
We cover 7 towns in Northamptonshire, including Northampton, Corby, Kettering, Wellingborough, Rushden and more.
Wind-driven rain is the first thing the surveyor weighs up. 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.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Northamptonshire properties, so you can choose who fixes them. 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 refill at all?
Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
