Timber glazing upgrades in Cheltenham
If Slim Cavity Units in Cheltenham were straightforward, there would be a stock size for it. Property here runs to Cotswold stone with stone-mullion openings and Regency Cheltenham terraces, and each of those brings its own set of dimensions. Then there is high rainfall on the escarpment with valley frost pockets, which reliably produces decay where timber sits directly against saturated stone reveals given enough seasons. Everything we do here comes back to narrow cavities that perform while keeping the sightline historic.
Each opening is recorded individually, since a terrace of identical houses rarely is. Photographs and approximate sizes are all we need to start.
One thing that catches people out here: Cotswold planning policy is strict on window proportion and glazing bar width.

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

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.
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.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
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.
