Timber glazing upgrades in Sedgefield
The hard part of Secondary Glazing in Sedgefield is not the making, it is the measuring. Most of what we survey locally is colliery terraces, Georgian Durham city stock and Pennine stone housing, which is not built to any modern module. The exposure here is cold upland winters with heavy rainfall, which is exactly the condition that causes frost and saturation damage on unmaintained painted softwood. Everything we do here comes back to 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. We will price it properly in writing, and we will tell you if it is not worth doing.
Local factor worth flagging early: Durham's cathedral setting carries World Heritage-level design scrutiny.

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

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.
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.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
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.
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.
