Timber glazing upgrades in Bicester
Secondary Glazing in Bicester is rarely a catalogue job. You are mostly dealing with Cotswold stone cottages, Georgian college-town terraces and new-build fringe estates around here, so openings vary more than people expect. The exposure here is river-valley mist and prolonged autumn damp, which is exactly the condition that causes rot behind stone reveals where water tracks in at the joint. In practice that means internal glazing that leaves the original window entirely untouched.
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.
Bear in mind for this area: 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.”

Is the timber certified?
All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.
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.
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 deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
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.
