Timber glazing upgrades in Middlesbrough
Misted Unit Replacement in Middlesbrough is rarely a catalogue job. Property here runs to medieval York frontages, Dales stone farmhouses and Victorian coastal resorts, and each of those brings its own set of dimensions. With severe North Sea exposure on the coast and upland cold in the Dales in the mix, salt and wind damage at the coast, frost damage inland is a question of when rather than whether. Where we put the effort is swapping the failed unit rather than selling you a whole window.
The measuring is done by the people responsible for the fit, which concentrates the mind. Tell us what you are working with and we will put a fixed figure in writing.
Worth knowing locally: York's historic core requires close matching of historic glazing bar profiles.

“The survey showed most of the loss was around the frames, not through the glass at all.”

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.
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 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.
