Timber glazing upgrades in Askern
Slim Cavity Units across Askern tends to be driven by the condition of what is already there. Local property is overwhelmingly steel-era terraces, interwar council stock and stone village housing, which is why we never quote from a catalogue. 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. In practice that means narrow cavities that perform while keeping the sightline historic.
Each opening is recorded individually, since a terrace of identical houses rarely is. Send what you have, even if it is only a phone photo, and we will take it from there.
One thing that catches people out here: large volumes of pre-1919 stock make sash repair the dominant enquiry.

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.
