Double Glazing Windows

Transforming your Mwyndy home with new windows will mean enjoying higher levels of home security, thermal efficiency and weather protection. Our double glazing offers more than just sleek designs, our windows are manufactured with longevity in mind so that your products stand the test of time. Our double glazing windows are incredibly low-maintenance due to the uPVC or aluminium framing that you choose.

Mwyndy homeowners looking to replace older steel or timber windows should browse our range of designs, as all of our double glazing can be tailored to fit the style of any property. Unlike older windows, our profiles will not bow, warp or rot, even after prolonged exposure to the Welsh elements. Our double glazing windows will provide excellent protection against both the changeable weather and unwanted visitors. Fitted as standard with industry-leading locking systems and stress resistance double glazing, our windows will withstand even the most determined burglar attempts.

We want our customers to celebrate their unique style and for their new double glazing windows to reflect this. At Leekes we have a window for every style of property, whether it be modern, heritage or period. Our windows can be manufactured bespoke to your specifications, including the choice of a range of colours, finishes and hardware accessories.

Our range of double glazing windows includes; uPVC Casement Windows, uPVC Tilt & Turn Windows, uPVC Bow & Bay Windows, uPVC Flush Casement Windows, uPVC Sliding Sash Windows and Aluminium Windows

Conservatory Roofs

The most important part of a conservatory is not the doors or the windows but is in fact the conservatory roof. We fit four different roof styles that can transform an existing conservatory into a space that can be enjoyed year-round, or act as the perfect finishing touch to a new extension.

Each one offers a range of different benefits and can be customised to your requirements, so if you want to flood your conservatory with light, you can.

Here are the replacement roofs we offer: Solid Conservatory Roof, Tiled Conservatory Roof, Glass Roof, UltraSky.

Orangeries and House Extensions

If you want an extra space for your Mwyndy home that offers more privacy and blends into the architecture of your existing build, then the orangery or extension is ideal. This extension offers you a more secure space that you can enjoy year-round, even in the coldest of Welsh winters. Choose from our Orangeries, Kitchen Orangeries or Extensions.
