Slim Cavity Glazing across Hertfordshire

If you are looking at Slim Cavity Glazing in Hertfordshire, the timber is only half the decision. You are mostly dealing with garden city stock, Georgian market town frontages and commuter-belt detached housing around here, so openings vary more than people expect. moderate rainfall with cold inland frosts sets the pace of decay, and frost damage to end grain and swelling on unbalanced-finished units is how it shows up first. This is really a job about getting a sealed unit into a historic sightline without bulking it out.

Manufacture only starts once the survey figures are agreed with you in writing. Rough dimensions and a couple of photographs are enough for us to price it properly.

A local consideration we always raise: garden city areas carry design codes that restrict window style changes.

Towns covered

Replication, not approximation

Profiles copied from the surviving original, section by section.

Conservation glazing

Slim-cavity units and genuine putty lines where the consent requires them.

Fabric retained where possible

We splice and repair before we replace, because the original is the point.

Frequently asked questions

Do you cover Hertfordshire?

Yes. We cover the whole of Hertfordshire including Watford, St Albans, Hemel Hempstead, Stevenage and the surrounding villages. Garden city areas carry design codes that restrict window style changes. Because moderate rainfall with cold inland frosts, we allow for it at survey stage rather than discovering it on the day.

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.

Do you take a deposit?

Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.

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.

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.
