Sash window repair in Welwyn Garden City
People come to us about Secondary Glazing in Welwyn Garden City once the cheap option has already failed. Local property is overwhelmingly garden city stock, Georgian market town frontages and commuter-belt detached housing, which is why we never quote from a catalogue. The weather does the rest: moderate rainfall with cold inland frosts here, and frost damage to end grain and swelling on unbalanced-finished units as the predictable result. What you are paying for is internal glazing that improves comfort without touching the original.
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.
Worth knowing locally: garden city areas carry design codes that restrict window style changes.

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.
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.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
