Timber glazing upgrades in King's Lynn
Getting Secondary Glazing right in King's Lynn depends on detail that a price list cannot capture. Local property is overwhelmingly flint and pantile cottages, Georgian merchant houses and coastal resort stock, which is why we never quote from a catalogue. The exposure here is exposed North Sea easterlies with salt-laden wind, which is exactly the condition that causes salt damage and finish erosion on east-facing coastal elevations. This is really a job about internal glazing that leaves the original window entirely untouched.
We would rather spend an hour surveying than a week correcting. Rough dimensions and a couple of photographs are enough for us to price it properly.
Something particular to this area: flint walls give minimal reveal, so weathering detail carries the whole load.

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

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 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.
