Timber glazing upgrades in Diss
Slim Cavity Units in Diss is rarely a catalogue job. Local property is overwhelmingly flint and pantile cottages, Georgian merchant houses and coastal resort stock, which is why we never quote from a catalogue. Then there is exposed North Sea easterlies with salt-laden wind, which reliably produces salt damage and finish erosion on east-facing coastal elevations given enough seasons. What you are paying for is narrow cavities that perform while keeping the sightline historic.
A surveyor visits first and records the real dimensions, at several points on each opening. Get in touch and we will be straight with you about cost and timescale.
Bear in mind for this area: flint walls give minimal reveal, so weathering detail carries the whole load.

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

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.
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 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.
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.
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.
