Sash window repair in Dumbarton
Draught Proofing is one of those jobs in Dumbarton where the survey decides everything. The building stock is sandstone tenements, Georgian New Town terraces and post-war housing schemes, so we expect variation before we ever pick up a tape. Because of cold wet winters with strong westerly exposure, we see sash and case failure in tenement stock and cill decay at stone junctions more often here than in most of the country. Our focus on this is sealing the perimeter without making the sash stiff to operate.
We would rather spend an hour surveying than a week correcting. Give us the basics and you will have a written figure, not a range that moves later.
A local consideration we always raise: Scottish sash and case construction differs from English box sash and needs matching.

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.
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.
