Existing insulation and guarantee check for Gerrards Cross properties
Gerrards Cross is among the towns we cover in Buckinghamshire, alongside Chalfont Saint Peter, Amersham and Chesham. It is around 33 miles south of Milton Keynes.
Buyers and sellers in Gerrards Cross often book this check when a survey report or EPC raises questions about the walls. A survey in Gerrards Cross gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Before any material is chosen, exposure is checked. Much of Buckinghamshire 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.
In terms of approvals, if cavity wall insulation follows in Gerrards Cross, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
