Slim Cavity Units across Buckinghamshire
The hard part of Slim Cavity Units in Buckinghamshire is not the making, it is the measuring. Property here runs to Chiltern brick-and-flint cottages alongside large modern estates, and each of those brings its own set of dimensions. Add chalk-valley damp with cold air pooling overnight to that and persistent condensation staining and cill rot on older single-glazed units becomes the usual trigger for replacement. Where we put the effort is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. Send what you have, even if it is only a phone photo, and we will take it from there.
One local point to factor in: AONB designation across much of the county tightens external alteration consent.

Frequently asked questions
Do you cover Buckinghamshire?
Yes. We cover the whole of Buckinghamshire including Milton Keynes, High Wycombe, Aylesbury, Amersham and the surrounding villages. AONB designation across much of the county tightens external alteration consent. Because chalk-valley damp with cold air pooling overnight, we allow for it at survey stage rather than discovering it on the day.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
