Timber glazing upgrades in Gainsborough
Retrofit Double Glazing in Gainsborough is rarely a catalogue job. You are mostly dealing with Georgian Stamford limestone, fenland farmhouses and coastal resort bungalows around here, so openings vary more than people expect. With low rainfall with severe exposed easterly wind off the North Sea in the mix, wind-driven rain ingress and sand abrasion on coastal finishes is a question of when rather than whether. This is really a job about reworking the rebate so a sealed unit fits without bulking the section.
A surveyor visits first and records the real dimensions, at several points on each opening. We will price it properly in writing, and we will tell you if it is not worth doing.
One thing that catches people out here: 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 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 match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
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.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
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.
