Timber glazing upgrades in Knaresborough
Misted Unit Replacement across Knaresborough tends to be driven by the condition of what is already there. Local property is overwhelmingly medieval York frontages, Dales stone farmhouses and Victorian coastal resorts, which is why we never quote from a catalogue. severe North Sea exposure on the coast and upland cold in the Dales sets the pace of decay, and salt and wind damage at the coast, frost damage inland is how it shows up first. Where we put the effort is swapping the failed unit rather than selling you a whole window.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. One call is usually enough for us to tell you roughly where the price will land.
One local point to factor in: York's historic core requires close matching of historic glazing bar profiles.

“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.
