Timber glazing upgrades in Falmouth
Most Slim Cavity Units enquiries we take in Falmouth start with an opening that is not a standard size. You will find mostly granite fishermen's cottages, slate-hung terraces and modern coastal builds in this area, and it moves as it ages. Set against the most severe salt and wind exposure in England, most joinery here eventually shows accelerated coating failure and salt crystallisation damage at glazing lines. What you are paying for is narrow cavities that perform while keeping the sightline historic.
Nothing is ordered until someone has stood in front of the opening with a tape. A quick call or a photograph of the opening is usually enough to get you a price.
Bear in mind for this area: Cornish exposure grades mean specification should assume worst-case wind-driven rain.

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

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.
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.
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.
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 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.
