Timber glazing upgrades in Plymouth
Slim Cavity Units in Plymouth is rarely a catalogue job. Property here runs to cob and thatch, Regency seaside terraces and Dartmoor granite cottages, and each of those brings its own set of dimensions. Add the wettest large county in England with severe Atlantic exposure to that and sustained rot in cob-embedded frames and moor-exposed openings becomes the usual trigger for replacement. The part that matters is narrow cavities that perform while keeping the sightline historic.
The survey happens before manufacture, which is why our units fit without packing or trimming. Send us sizes and a photograph and we will come back with a fixed written price.
A local consideration we always raise: cob walls move seasonally, so frames need tolerance built into the fixing detail.

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

What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
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 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 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.
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.
