Sash window repair in Darlington
People come to us about Draught Proofing in Darlington once the cheap option has already failed. You are mostly dealing with colliery terraces, Georgian Durham city stock and Pennine stone housing around here, so openings vary more than people expect. Locally you are contending with cold upland winters with heavy rainfall, so frost and saturation damage on unmaintained painted softwood is the fault we are called out to. Where we put the effort is sealing the perimeter without making the sash stiff to operate.
Nothing is ordered until someone has stood in front of the opening with a tape. Give us the basics and you will have a written figure, not a range that moves later.
Worth knowing locally: Durham's cathedral setting carries World Heritage-level design scrutiny.

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.
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.
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 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 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.
