Timber glazing upgrades in Barnard Castle
The Thermal Survey we make for Barnard Castle is set out from a survey, not a size chart. Because the area is mainly colliery terraces, Georgian Durham city stock and Pennine stone housing, no two openings measure quite the same. Then there is cold upland winters with heavy rainfall, which reliably produces frost and saturation damage on unmaintained painted softwood given enough seasons. Our focus on this is measuring where heat is going before anyone recommends a spend.
We check on site before committing anything to the saw, and we query what does not add up. Get in touch and we will be straight with you about cost and timescale.
One local point to factor in: 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.”

How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
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.
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 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.
