Timber glazing upgrades in Henley-on-Thames
Half the Slim Cavity Units problems we fix in Henley-on-Thames started as a sizing assumption. You will find mostly Cotswold stone cottages, Georgian college-town terraces and new-build fringe estates in this area, and it moves as it ages. The weather does the rest: river-valley mist and prolonged autumn damp here, and rot behind stone reveals where water tracks in at the joint as the predictable result. What we concentrate on is narrow cavities that perform while keeping the sightline historic.
The survey happens before manufacture, which is why our units fit without packing or trimming. Send us sizes and a photograph and we will come back with a fixed written price.
Worth knowing locally: listed and curtilage-listed properties are unusually common in the historic centres.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Oxfordshire“Half the cost of replacement and the rooms hold heat noticeably better.”

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 deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
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 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.
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.
