Timber glazing upgrades in Sheffield
We take a fair volume of Retrofit Double Glazing work across Sheffield, and almost none of it repeats. Around here it is steel-era terraces, interwar council stock and stone village housing, and that alone rules out anything bought by the pallet. cold inland winters with prolonged damp is the local complication, and condensation-driven decay on single-glazed units in unheated rooms is what it eventually causes. What we concentrate on is reworking the rebate so a sealed unit fits without bulking the section.
We would rather spend an hour surveying than a week correcting. Send us sizes and a photograph and we will come back with a fixed written price.
A detail specific to this area: large volumes of pre-1919 stock make sash repair the dominant enquiry.

Feedback collected directly from completed projects. Full written references are available on request before you commit.
“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, South Yorkshire“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, South Yorkshire“They fitted trickle vents we had not thought about, which stopped the condensation.”
Verified client, South YorkshireSheffield questions
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.
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.
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 deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
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.
