What we see in North Wales
Retrofit Double Glazing is one of those jobs in North Wales where the survey decides everything. Property here runs to slate-quarry terraces, Victorian resort stock and stone farmhouses, and each of those brings its own set of dimensions. Set against severe Irish Sea exposure with very high rainfall, most joinery here eventually shows salt and rain combining to strip finishes and open glazing joints. The value is in reworking the rebate so a sealed unit fits without bulking the section, not in the timber bill.
The measuring is done by the people responsible for the fit, which concentrates the mind. We will price it properly in writing, and we will tell you if it is not worth doing.
One thing that catches people out here: Llandudno's Victorian frontages are protected as a coherent conservation set.

“The survey showed most of the loss was around the frames, not through the glass at all.”

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.
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.
