Timber glazing upgrades in Sleaford
Ask three firms about Slim Cavity Units in Sleaford and you will get three different answers. Around here it is Georgian Stamford limestone, fenland farmhouses and coastal resort bungalows, and that alone rules out anything bought by the pallet. Because of low rainfall with severe exposed easterly wind off the North Sea, we see wind-driven rain ingress and sand abrasion on coastal finishes more often here than in most of the country. Where we put the effort is narrow cavities that perform while keeping the sightline historic.
The measuring is done by the people responsible for the fit, which concentrates the mind. Send us sizes and a photograph and we will come back with a fixed written price.
A detail specific to this area: 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.”

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