Borescope cavity inspection in Greater London

A borescope inspection pushes a small camera through a hole about the size of a pencil into the cavity to see whether it is empty, partly filled or filled, what the fill is and whether there is debris. Our Greater London coverage includes London, Islington, Bexley and the towns around them.

Borescope cavity inspection across Greater London

We cover 81 towns in Greater London, including London, Islington, Bexley, Barking, Archway and more.

Local weather affects which walls can be filled. Much of Greater London 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.

The written result for your Greater London property is plain English: what we found, what it means and what, if anything, to do next. A survey in Greater London gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

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.

How many holes?

Enough to be representative: typically several per elevation, plus targeted checks below windows, at corners and near any damp patches. Each one is photographed and logged.
