Damp investigation after cavity insulation for Oxford properties
We cover Oxford and the OX1 postcode district, including nearby Abingdon, Didcot and Witney. Oxford is one of the main towns we cover in Oxfordshire.
Where an Oxford 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. Damp in an insulated Oxford home is not always the insulation's fault, so the diagnosis comes before any extraction.
Before any material is chosen, exposure is checked. Much of Oxfordshire 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 Oxford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
