Borescope cavity inspection for Coulsdon properties
If your property is in Coulsdon or the CR5 district or nearby Purley, Wallington and Sutton, it is within our Greater London coverage. It is about 13 miles south of London.
Where a Coulsdon wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. A survey in Coulsdon gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Every elevation is judged on its own exposure. 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.
On the rules side, if cavity wall insulation follows in Coulsdon, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
