Timber glazing upgrades in High Wycombe
There is no standard version of Slim Cavity Units in High Wycombe, which is rather the point. The building stock is Chiltern brick-and-flint cottages alongside large modern estates, so we expect variation before we ever pick up a tape. Set against chalk-valley damp with cold air pooling overnight, most joinery here eventually shows persistent condensation staining and cill rot on older single-glazed units. The value is in narrow cavities that perform while keeping the sightline historic, not in the timber bill.
Each opening is recorded individually, since a terrace of identical houses rarely is. Get in touch and we will be straight with you about cost and timescale.
One thing that catches people out here: AONB designation across much of the county tightens external alteration consent.

“The survey showed most of the loss was around the frames, not through the glass at all.”

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.
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.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
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.
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.
