Timber glazing upgrades in Crook
Draught Sealing across Crook tends to be driven by the condition of what is already there. Local property is overwhelmingly colliery terraces, Georgian Durham city stock and Pennine stone housing, which is why we never quote from a catalogue. With cold upland winters with heavy rainfall in the mix, frost and saturation damage on unmaintained painted softwood is a question of when rather than whether. Where we put the effort is sealing the perimeter without making anything stiff to open.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. Get in touch and we will be straight with you about cost and timescale.
One thing that catches people out here: 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.”

Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
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.
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.
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.
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.
