Slim Cavity Units across Cardiff and South Wales
People come to us about Slim Cavity Units in Cardiff and South Wales once the cheap option has already failed. Because the area is mainly valleys terraces, Victorian maritime villas and civic Portland stone frontages, no two openings measure quite the same. Add very high rainfall with strong Atlantic and Bristol Channel exposure to that and prolonged wetting decay and finish failure on valley-facing elevations becomes the usual trigger for replacement. Where we put the effort is narrow cavities that perform while keeping the sightline historic.
The site visit comes first, because assumptions made in an office get paid for on site. Rough dimensions and a couple of photographs are enough for us to price it properly.
A local consideration we always raise: valleys terraces share a repeating bay and sash format that suits batch manufacture.

Frequently asked questions
Do you cover Cardiff and South Wales?
Yes. We cover the whole of Cardiff and South Wales including Cardiff, Swansea, Newport, Barry and the surrounding villages. Valleys terraces share a repeating bay and sash format that suits batch manufacture. Because very high rainfall with strong Atlantic and Bristol Channel exposure, we allow for it at survey stage rather than discovering it on the day.
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.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
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.
