Timber glazing upgrades in Caerphilly
If you are looking at Slim Cavity Units in Caerphilly, 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. The other factor is very high rainfall with strong Atlantic and Bristol Channel exposure, which is why prolonged wetting decay and finish failure on valley-facing elevations is the most common reason people call us. What we concentrate on 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 us sizes and a photograph and we will come back with a fixed written price.
A detail specific to this area: 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.”

Can you work on a listed building?
Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
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.
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.
