Timber glazing upgrades in Blaenau Ffestiniog
Ask three firms about Secondary Glazing in Blaenau Ffestiniog and you will get three different answers. Local stock is dominated by slate-quarry terraces, Victorian resort stock and stone farmhouses, which sets the sizes and profiles we work to. Set against severe Irish Sea exposure with very high rainfall, most joinery here eventually shows salt and rain combining to strip finishes and open glazing joints. In practice that means internal glazing that leaves the original window entirely untouched.
A surveyor visits first and records the real dimensions, at several points on each opening. Get in touch and we will be straight with you about cost and timescale.
One local point to factor in: Llandudno's Victorian frontages are protected as a coherent conservation set.

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

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.
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.
