Retrofit Double Glazing across North Wales

If you are looking at Retrofit Double Glazing in North Wales, the timber is only half the decision. Most of what we survey locally is slate-quarry terraces, Victorian resort stock and stone farmhouses, which is not built to any modern module. Add severe Irish Sea exposure with very high rainfall to that and salt and rain combining to strip finishes and open glazing joints becomes the usual trigger for replacement. What we concentrate on is reworking the rebate so a sealed unit fits without bulking the section.

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.

One thing that catches people out here: Llandudno's Victorian frontages are protected as a coherent conservation set.

Frequently asked questions

Do you cover North Wales?

Yes. We cover the whole of North Wales including Wrexham, Rhyl, Bangor, Colwyn Bay and the surrounding villages. Llandudno's Victorian frontages are protected as a coherent conservation set. Because severe Irish Sea exposure with very high rainfall, we allow for it at survey stage rather than discovering it on the day.

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.

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.

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.

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.
