Borescope cavity inspection for Isleworth properties
If your property is in Isleworth or the TW7 district or nearby Hounslow, Heston and Richmond, it is within our Greater London coverage. It is about 9 miles west of London.
Where an Isleworth wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Buyers and sellers in Isleworth often book this check when a survey report or EPC raises questions about the walls.
Exposure matters for every cavity wall. 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 Isleworth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

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.
