Timber glazing upgrades in Olney
What makes Secondary Glazing work in Olney is usually invisible once it is finished. Local stock is dominated by Chiltern brick-and-flint cottages alongside large modern estates, which sets the sizes and profiles we work to. The weather does the rest: chalk-valley damp with cold air pooling overnight here, and persistent condensation staining and cill rot on older single-glazed units as the predictable result. This is really a job about 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. Send what you have, even if it is only a phone photo, and we will take it from there.
Local factor worth flagging early: AONB designation across much of the county tightens external alteration consent.

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

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.
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.
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 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.
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.
