What we see in Cardiff and South Wales
Getting Retrofit Double Glazing right in Cardiff and South Wales depends on detail that a price list cannot capture. The housing here is largely valleys terraces, Victorian maritime villas and civic Portland stone frontages, and that shapes what will actually fit. Locally you are contending with very high rainfall with strong Atlantic and Bristol Channel exposure, so prolonged wetting decay and finish failure on valley-facing elevations is the fault we are called out to. What you are paying for is reworking the rebate so a sealed unit fits without bulking the section.
We check on site before committing anything to the saw, and we query what does not add up. Give us the basics and you will have a written figure, not a range that moves later.
Bear in mind for this area: valleys terraces share a repeating bay and sash format that suits batch manufacture.

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.
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.
