Timber glazing upgrades in Alnwick
If Thermal Survey in Alnwick were straightforward, there would be a stock size for it. With border stone farmhouses, colliery terraces and coastal fishing cottages making up much of the area, off-the-shelf sizes rarely line up. Locally you are contending with the harshest combination of cold, wind and salt in England, so combined frost and salt damage stripping finishes within a few seasons is the fault we are called out to. The part that matters is measuring where heat is going before anyone recommends a spend.
The survey happens before manufacture, which is why our units fit without packing or trimming. Rough dimensions and a couple of photographs are enough for us to price it properly.
Worth knowing locally: Northumberland exposure justifies the heaviest sections and stainless fixings.

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

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.
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.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
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.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
