Timber glazing upgrades in Blackwood
If you are looking at Slim Cavity Units in Blackwood, the timber is only half the decision. The housing here is largely valleys terraces, Victorian maritime villas and civic Portland stone frontages, and that shapes what will actually fit. Set against very high rainfall with strong Atlantic and Bristol Channel exposure, most joinery here eventually shows prolonged wetting decay and finish failure on valley-facing elevations. The part that matters is narrow cavities that perform while keeping the sightline historic.
Each opening is recorded individually, since a terrace of identical houses rarely is. Ask us for a figure and you will get one, with the lead time stated alongside it.
A local consideration we always raise: valleys terraces share a repeating bay and sash format that suits batch manufacture.

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

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.
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.
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 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.
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.
