Damp investigation after cavity insulation in Chalfont Saint Peter

Chalfont Saint Peter homeowners, buyers, landlords and agents can book a damp investigation with the price agreed first. A damp investigation finds out why an insulated wall is showing damp or mould: rain getting in through defects, bridged or wet fill, debris in the cavity, a breached damp-proof course, or condensation.

Damp investigation after cavity insulation for Chalfont Saint Peter properties

If your property is in Chalfont Saint Peter or the SL9 district or nearby Gerrards Cross, Amersham and Chesham, it is within our Buckinghamshire coverage. It is around 31 miles south of Milton Keynes.

If your Chalfont Saint Peter installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Chalfont Saint Peter wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

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.

As for paperwork, if cavity wall insulation follows in Chalfont Saint Peter, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
