Damp investigation after cavity insulation across Oxfordshire
We cover 6 towns in Oxfordshire, including Oxford, Banbury, Abingdon, Bicester, Didcot and more.
Every elevation is judged on its own exposure. Much of Oxfordshire 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.
Where an Oxfordshire 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 Oxfordshire installation has a guarantee, we check it first; the guarantee route may cover the work.
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.

Common causes we check
Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
