Cavity wall insulation removal for Bicester properties
Bicester sits in Oxfordshire, about 11 miles north-east of Oxford. We work across the OX26 district, including nearby Oxford, Banbury and Witney.
Where a Bicester 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. If your Bicester installation has a guarantee, we check it first; the guarantee route may cover the work.
Exposure matters for every cavity wall. 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.
On the rules side, if cavity wall insulation follows in Bicester, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Should I remove my cavity wall insulation?
Not always. Welsh Government guidance makes the point that extraction is not always the right remedy. Damp can come from blocked gutters, failed pointing, bridged damp-proof courses or condensation, none of which removal fixes. We start with a damp investigation and borescope checks, then recommend removal only where the fill itself is the problem.
