Timber glazing upgrades in Llanelli
What makes Secondary Glazing work in Llanelli is usually invisible once it is finished. Around here it is valleys terraces, Victorian maritime villas and civic Portland stone frontages, and that alone rules out anything bought by the pallet. 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. This is really a job about internal glazing that leaves the original window entirely untouched.
The site visit comes first, because assumptions made in an office get paid for on site. Tell us the problem rather than the solution and we will advise on both.
Bear in mind for 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.”

Verified client, Cardiff and South Wales“They fitted trickle vents we had not thought about, which stopped the condensation.”

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 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.
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.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
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.
