Timber glazing upgrades in Crowthorne
People come to us about Secondary Glazing in Crowthorne once the cheap option has already failed. The building stock is Thames-side villas, Victorian terraces and dense 1980s commercial fit-out stock, so we expect variation before we ever pick up a tape. Then there is river humidity and localised flood exposure, which reliably produces swelling and binding on ground-floor doors after flood or high water table events given enough seasons. In practice that means internal glazing that leaves the original window entirely untouched.
We would rather spend an hour surveying than a week correcting. We will price it properly in writing, and we will tell you if it is not worth doing.
One thing that catches people out here: flood-zone properties benefit from raised thresholds and marine-grade fixings.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Berkshire“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Berkshire“They fitted trickle vents we had not thought about, which stopped the condensation.”

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.
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.
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.
