Our uPVC windows can be customised to match any Cardiff or South Wales home. The frame of the window can be decorated in a range of colour and woodgrain foils, letting you match it to existing uPVC doors. You can incorporate panes of decorative glazing into the design, allowing you to increase the privacy of your home whilst still letting in the light. By choosing Leekes, you can enjoy a window that matches the style of your home.

Here are Some Benefits of Choosing Our uPVC Windows


We give our Cardiff customers full confidence their home is secured with our uPVC windows. We fit our windows with some of the best locks available, with multi-point locking fitted as standard across the frame. When these locks are combined with the multi-chambered uPVC frame and the panes of glazing, it removes any potential weak spots that could be exploited.

For homeowners wanting the best security for their uPVC windows, they can upgrade them further. The Cardiff homeowner can incorporate the market-leading Yale secure lock into the window design. This is fitted on the frames and accompanied by a lifetime guarantee to provide year-after-year of protection.


Our uPVC windows are built with a multi-chambered frame, improving the thermal performance of your Cardiff home. The frame works in unison with the panes of double or triple glazing, trapping in pockets of warm air. This will help to retain a comfortable temperature within your South wales home throughout the year, even in the cold winter months.

As heat is retained in your Cardiff home for longer due to our uPVC windows, you can rely less upon your central heating for warmth. This will reduce your energy bills, providing you with more money to spend on the things you want. As the general energy consumption of the property lessens, so to will the carbon footprint.


Our uPVC windows are designed to keep the changeable South Wales weather out of your home. These windows are fitted with weatherseals and trickle vents. This will keep cold draughts and damp out of your property. Trickle vents will carry away rainfall, reducing the risk of standing water.

Even in the strongest of storms, our uPVC windows will retain the quality and keep the bad weather out of your Cardiff home. The colour is imbued into the frame of our windows, removing a need for repainting. The only maintenance required for our uPVC windows is to give them an occasional wipe down with a damp cloth to maintain the good-as-new look.


The Cardiff homeowner can have complete confidence they’ve invested in the best product by choosing our uPVC windows. We offer fully accredited windows that conforms and exceeds the latest building regulations and meet PAS24 standards. This means you’ll get a lasting product, providing the best performance for many years to come.
