Timber glazing upgrades in Hitchin
What makes Slim Cavity Units work in Hitchin is usually invisible once it is finished. Local stock is dominated by garden city stock, Georgian market town frontages and commuter-belt detached housing, which sets the sizes and profiles we work to. Set against moderate rainfall with cold inland frosts, most joinery here eventually shows frost damage to end grain and swelling on unbalanced-finished units. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
The site visit comes first, because assumptions made in an office get paid for on site. We will price it properly in writing, and we will tell you if it is not worth doing.
Bear in mind for this area: 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.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
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.
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.
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.
