Existing insulation and guarantee check for Gravesend properties

Our Kent coverage takes in Gravesend (DA11) and nearby Strood, Dartford and Rochester. It is around 14 miles north-west of Maidstone.

A survey in Gravesend gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Where a Gravesend wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

Wind-driven rain is the first thing the surveyor weighs up. Much of Kent 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.

For regulations, if cavity wall insulation follows in Gravesend, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
