Borescope cavity inspection for Hanworth properties
We cover Hanworth and the TW13 postcode district, including nearby Hampton, Feltham and Hounslow. It is about 12 miles south-west of London.
Where a Hanworth wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. The written result for your Hanworth property is plain English: what we found, what it means and what, if anything, to do next.
Before any material is chosen, exposure is checked. 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.
As for paperwork, if cavity wall insulation follows in Hanworth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

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.
