Timber glazing upgrades in Guidepost
Slim Cavity Units across Guidepost tends to be driven by the condition of what is already there. Local property is overwhelmingly border stone farmhouses, colliery terraces and coastal fishing cottages, which is why we never quote from a catalogue. What accelerates it is the harshest combination of cold, wind and salt in England, and combined frost and salt damage stripping finishes within a few seasons follows sooner than owners expect. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. We will price it properly in writing, and we will tell you if it is not worth doing.
A detail specific to this area: Northumberland exposure justifies the heaviest sections and stainless fixings.

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.
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.
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 deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
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.
