Timber glazing upgrades in Stevenage
Misted Unit Replacement in Stevenage rewards patience at the setting-out stage. Local stock is dominated by garden city stock, Georgian market town frontages and commuter-belt detached housing, which sets the sizes and profiles we work to. With moderate rainfall with cold inland frosts in the mix, frost damage to end grain and swelling on unbalanced-finished units is a question of when rather than whether. In practice that means swapping the failed unit rather than selling you a whole window.
We check on site before committing anything to the saw, and we query what does not add up. Give us the basics and you will have a written figure, not a range that moves later.
Something particular to this area: garden city areas carry design codes that restrict window style changes.

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

What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
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.
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.
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.
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.
