The Most Popular Window in Llantrisant

The casement window is one of the most popular uPVC windows installed in homes across Llantrisant and Rhondda Cynon Taff. Casement windows are one of the most customisable window styles on the market and can be designed to suit any property type. You’ll be able to choose from a variety of colour and woodgrain foil options to decorate the frame, giving you a window the match the look and style of the property. For homeowners wanting to replace old timber or steel windows, this window is the perfect upgrade.

Our modern casement windows don’t offer the same high maintenance issues to the Llantrisant homeowner, making them the perfect replacement for timber windows. The weatherseals fitted across the frame keep cold draughts and dampness out of the property. The window frame will retain the good-as-new look for many years to come, even after regular exposure to the changeable Rhondda Cynon Taff weather. These uPVC windows will not warp, bow, crack, twist, flake or discolour, continuing to retain the good-as-new look.

Benefits of Our uPVC Casement Windows


You’ll do your bit for the environment by investing in our casement windows for your Llantrisant home. These casement replacement windows are multi-chambered in their design, working alongside the panes of double or triple glazing to trap warm air within your home. This will help you to keep your Rhondda Cynon Taff property year-round, even in the cold winter months. 

With your casement windows retaining heat within your Llantrisant property, you can rely less on your central heating for natural warmth. This means your energy bills will reduce, freeing up money you can spend on the things you want and need. As less energy is consumed within your Rhondda Cynon Taff home, the overall carbon footprint of the property will shrink.


The security of your Llantrisant home is something we take very seriously here at Leekes. That’s why we offer replacement casement windows that are designed and tested to PAS24 certification. The multi-chambered uPVC  frame works alongside the panes of glazing and locks, creating a high level of security across the whole window.

As standard, we fit multi-point locking on the frames of our casement windows. This eliminates any potential weak spots that could be exploited by would-be intruders looking to access your Llantrisant home. For homeowners wanting the best level of security, you can choose the market-leading Yale lock. This is accompanied by a lifetime guarantee, providing you with the best level of security for many years to come.


The Llantrisant homeowner will enjoy protection against the changeable South Wales weather through our casement windows. Weatherseals and a drainage system are fitted within the window. This works to carry water away from your Rhondda Cynon Taff home, eliminating the risk of standing water that can cause damage to the property.

Our casement windows will continue to retain their quality, even after constant exposure to the changeable Llantrisant weather. Unlike the old timber casement designs, our uPVC frame will not crack, bow, warp, flake or be at risk of mould. The colour has been imbued into the frame and will not require repainting. The only maintenance the Rhondda Cynon Taff homeowner needs to carry out on our windows is to give the frame an occasional wipe down with a damp cloth, retaining the good-as-new look.


You’ll be choosing the best service, product and installer when you use Leekes for our casement windows. We offer windows created to the highest standards, offering you complete peace of mind that you’ve got the best window for your property. All the windows we install meet PAS24 requirements and exceed the latest UK Building Regulations.

After many years of installing casement windows and other double glazing products, Leekes has created a reputation of quality. By choosing us, you’ll choose a window from a FENSA and TrustMark accredited installer, as well as a member of the Ultraframe Ultra Installer network. Our quality was further recognised at the G19 awards, where Leekes was listed as a finalist for Installer of the Year and Sustainability Initiative of the Year.
