Borescope cavity inspection across Essex
We cover 21 towns in Essex, including Southend-on-Sea, Basildon, Colchester, Chelmsford, Harlow and more.
Local weather affects which walls can be filled. Much of Essex 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.
A survey in Essex gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Essex often book this check when a survey report or EPC raises questions about the walls.
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.

When a borescope check helps
Before filling, to confirm the cavity is empty and clean. Before buying a house, to see if the EPC's claim of 'filled cavity' is true. When damp has appeared and you need to know whether the fill is wet or bridged. Before a top-up, to map which panels are empty.
