Slim Cavity Units for Dursley properties
Most Slim Cavity Units enquiries we take in Dursley start with an opening that is not a standard size. The housing here is largely Cotswold stone with stone-mullion openings and Regency Cheltenham terraces, and that shapes what will actually fit. The exposure here is high rainfall on the escarpment with valley frost pockets, which is exactly the condition that causes decay where timber sits directly against saturated stone reveals. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
A surveyor visits first and records the real dimensions, at several points on each opening. A quick call or a photograph of the opening is usually enough to get you a price.
One thing that catches people out here: Cotswold planning policy is strict on window proportion and glazing bar width.
