Timber windows in Dumbarton
If you are looking at Casement Windows in Dumbarton, the timber is only half the decision. With sandstone tenements, Georgian New Town terraces and post-war housing schemes making up much of the area, off-the-shelf sizes rarely line up. With cold wet winters with strong westerly exposure in the mix, sash and case failure in tenement stock and cill decay at stone junctions is a question of when rather than whether. What you are paying for is casements set out so the opening lights land where you actually want them.
We would rather spend an hour surveying than a week correcting. Rough dimensions and a couple of photographs are enough for us to price it properly.
Bear in mind for this area: Scottish sash and case construction differs from English box sash and needs matching.

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.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
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.
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.
