A survey in Warwick gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Warwick often book this check when a survey report or EPC raises questions about the walls.

Every elevation is judged on its own exposure. Much of Warwickshire 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.
