Slim Cavity Units across Oxfordshire
There is no standard version of Slim Cavity Units in Oxfordshire, which is rather the point. Local stock is dominated by Cotswold stone cottages, Georgian college-town terraces and new-build fringe estates, which sets the sizes and profiles we work to. Because of river-valley mist and prolonged autumn damp, we see rot behind stone reveals where water tracks in at the joint more often here than in most of the country. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
The measuring is done by the people responsible for the fit, which concentrates the mind. We will price it properly in writing, and we will tell you if it is not worth doing.
Worth knowing locally: listed and curtilage-listed properties are unusually common in the historic centres.

Frequently asked questions
Do you cover Oxfordshire?
Yes. We cover the whole of Oxfordshire including Oxford, Banbury, Bicester, Abingdon and the surrounding villages. Listed and curtilage-listed properties are unusually common in the historic centres. Because river-valley mist and prolonged autumn damp, we allow for it at survey stage rather than discovering it on the day.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
Is the timber certified?
All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.
