uPVC Casement Windows

Llanharan


Improve your Llanharan home with our range of Casement Windows. We install uPVC windows across Llanharan and Rhondda Cynon Taff. Call our team today to find out how our uPVC Casement Windows are the perfect replacement for old timber or steel windows.

The Window Style to Suit All Homes

Our range of uPVC Casement Windows is one of the most popular windows installed in Llanharan and Rhondda Cynon Taff.  These uPVC windows fit seamlessly in both modern and traditional properties, suiting the styles of both. Manufactured with our quality uPVC profile, these windows will increase the security, weatherproofing and thermal performance of your property.

Our Casement Windows, like the rest of the uPVC designs we offer, can be customised in a range of woodgrain foil and colour options. If you want to replace old timber windows, decorating our casement design in a woodgrain foil is the best choice. Unlike timber, you won’t be left carrying out high maintenance tasks. For more modern Llanharan properties, our bolder colours are perfect for contemporary properties.

Benefits of Our uPVC Casement Windows


Our uPVC Casement Windows will help the Llanharan homeowner do their bit for the environment and save them money. The uPVC profiles we use are multi-chambered, with the frame working alongside the panes of double glazing to trap in pockets of warm air. This will allow your Rhondda Cynon Taff property to maintain a comfortable temperature year-round, even in the cold winter months. 

With your Llanharan home retaining its heat, you’ll rely less upon your central heating to warm your home. This will lead to your energy bills reducing, giving you more money on the things you enjoy. As your energy consumption reduces, your casement windows will help to shrink your Rhondda Cynon Taff property’s carbon footprint.


We take safety seriously when we offer our Casement Windows to our customers. That’s why we offer uPVC windows that are designed to protect your Llanharan home from modern burglary methods. These windows are built to a PAS24 standard of security, giving you peace of mind you’re only getting the best quality for your property.

The multi-chambered design of our casement windows works alongside the panes of double or triple glazing and the multi-point locks. Each one eliminates any potential weak spots that could be exploited. This gives you complete peace of mind your Llanharan property is protected.

For those wanting the best security for their casement windows, we offer the perfect upgrade. The Llanharan homeowner can upgrade to the market-leading Yale lock. This lock is accompanied by a lifetime guarantee, offering year after year of quality use.


Through using our modern uPVC profile, our casement windows will protect your Llanharan home from the changeable Rhonda Cynon Taff weather. Each window is fitted with drainage systems and weatherseals. This removes the risk of standing water as the rain is carried away from your property. 

The uPVC frame of our casement windows will continue to retain its quality, even after constant exposure to the changeable elements. Unlike timber or wooden frames, these windows will not warp, bow, twist, rot, crack, flake or mould. The colour is imbued within the material and will not require repainting. The only maintenance the Llanharan homeowner will need to carry out is to give the window an occasional wipe down with a damp cloth to maintain the good-as-new look.


When choosing an installer to fit casement windows, it’s important you receive a quality product that’s matched with a quality service. By choosing Leekes, you’ll get a product manufactured to the highest standards. Our windows are made to PAS24 specifications, meeting and exceeding the current UK Building Regulations.

We think it’s important as an installer to give the Llanharan homeowner the peace of mind to go ahead with their installations. That’s why we take great pride in our accreditations that recognise our commitment to quality. We are accredited by FENSA, TrustMark and we are a member of the Ultraframe Ultra Installer Network. At the G19 Awards, our quality was further recognised when Leekes was named as a finalist for Installer of the Year and Sustainability Initiative of the Year.
