Cavity insulation for new builds and extensions for Abingdon properties
If your property is in Abingdon or the OX14 district or nearby Didcot, Oxford and Witney, it is within our Oxfordshire coverage. It is about 6 miles south of Oxford.
Most Abingdon houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. A suitable wall in Abingdon is usually filled in a single day from outside, with drill holes made good to match the pointing.
Every elevation is judged on its own exposure. 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.
As for paperwork, in Abingdon filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Extensions that join an older house
Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
