Wall tie replacement 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. We never cold-call in Northamptonshire or anywhere else, and we do not work with doorstep claims companies.
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.

Signs of wall tie failure
Horizontal cracks in mortar joints at regular vertical intervals, bulging brickwork, or lifting of the roof verge. Older galvanised ties, especially in walls built before the 1980s, are the usual suspects.
