Timber glazing upgrades in Hertford
If you are looking at Draught Sealing in Hertford, the timber is only half the decision. The building stock is garden city stock, Georgian market town frontages and commuter-belt detached housing, so we expect variation before we ever pick up a tape. With moderate rainfall with cold inland frosts in the mix, frost damage to end grain and swelling on unbalanced-finished units is a question of when rather than whether. In practice that means sealing the perimeter without making anything stiff to open.
We would rather spend an hour surveying than a week correcting. A quick call or a photograph of the opening is usually enough to get you a price.
One thing that catches people out here: 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.”

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