Timber glazing upgrades in Long Sutton
Most Slim Cavity Units enquiries we take in Long Sutton start with an opening that is not a standard size. Local stock is dominated by Georgian Stamford limestone, fenland farmhouses and coastal resort bungalows, which sets the sizes and profiles we work to. Then there is low rainfall with severe exposed easterly wind off the North Sea, which reliably produces wind-driven rain ingress and sand abrasion on coastal finishes given enough seasons. What we concentrate on 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 what you have, even if it is only a phone photo, and we will take it from there.
A local consideration we always raise: Stamford is one of England's most tightly controlled conservation towns.

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

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.
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.
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.
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.
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.
