Timber glazing upgrades in Borehamwood
There is no standard version of Secondary Glazing in Borehamwood, which is rather the point. With garden city stock, Georgian market town frontages and commuter-belt detached housing making up much of the area, off-the-shelf sizes rarely line up. The other factor is moderate rainfall with cold inland frosts, which is why frost damage to end grain and swelling on unbalanced-finished units is the most common reason people call us. What you are paying for is internal glazing that leaves the original window entirely untouched.
A surveyor visits first and records the real dimensions, at several points on each opening. Send what you have, even if it is only a phone photo, and we will take it from there.
Worth knowing locally: garden city areas carry design codes that restrict window style changes.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Hertfordshire“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Hertfordshire“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.
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.
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.
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.
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.
