uPVC Casement Windows

Llandeilo


Leekes installs casement windows in homes across Llandeilo and Carmarthenshire. These windows are one of the most popular uPVC designs we install and the perfect timber or steel window replacement. Call our team today to find out how our casement windows will improve your property.

Carmarthenshire’s Most Popular Window

Due to their flexible design, our Casement Windows are one of the most popular uPVC windows installed in homes across Llandeilo and Carmarthenshire. This window design offers the ideal fit for both traditional and modern properties and doesn’t make the homeowner customise on looks over performance. The quality uPVC profile these windows are designed with will help warm your home naturally, secure and weatherproof your property.

As with all our uPVC windows, our casement windows can be decorated in a range of colour and woodgrain foil options to suit your design. If you’re looking to replace wooden windows, the woodgrain foil is the perfect way to maintain the traditional look. Unlike timber, you won’t be given high maintenance headaches. For modern homeowners, a bolder colour will help to make your Carmarthenshire home stand out.

Benefits of Our uPVC Casement Windows


As more Llandeilo homeowners are environmentally aware, we offer our customers casement windows that will do their bit. The multi-chambered uPVC profile works alongside the panes of glazing, trapping in pockets of warm air. This creates a comfortable temperature within your Carmarthenshire home year-round, even in the colder winter months. 

With your Llandeilo home retaining its heat for longer, you’ll start to rely less on your central heating for warmth. This will lead to your energy bills reducing, giving you more money to spend on the things you want. For homeowners that want to make their home as thermally efficient as possible, we offer triple glazing options in our casement windows. With less energy consumed in your Llandeilo home, the carbon footprint of your property will shrink.


We take security seriously with our uPVC windows. That’s why our casement windows are manufactured to offer protection against modern day burglary methods. These windows hold the PAS24 accreditation, highlighting their quality.

The multi-chambered profile of these windows works alongside panes of glazing and multi-point locking. Each piece removes any potential weak points on the frame that can be exploited. This offers the Llandeilo homeowner complete peace of mind their property has the best protection.

For the Llandeilo homeowner that wants the very best security, we offer the ideal upgrade. We offer the market-leading Yale lock in our casement windows. This lock is accompanied by a lifetime guarantee to offer year after year of quality use.


Our Casement windows are designed to protect your Llandeilo home against the changeable elements. Fitted with weatherseals and drainage system, standing water is carried away from your home. This prevents damage that can be harmful. 

The uPVC frame of our casement windows continues to retain its quality, even after constant exposure to the changeable Llandeilo weather.  Unlike timber windows, uPVC will not warp, twist, bow, crack, rot, flake or be prone to mould. The colour has been imbued within the material and doesn’t need repainting. The only maintenance the homeowner will have to carry out is to give the window an occasional wipe down with a damp cloth to maintain the good-as-new look.


When identifying an installer of casement windows, it’s important that you get a quality product that is matched by a quality service. By choosing Leekes, you’ll receive a casement window built to the highest standard. Are windows are manufactured to PAS24 standards, meeting and exceeding the current UK Building Regulations.

As an installer, we provide more peace of mind our casement windows are built to last through the accreditations we hold. We are currently accredited by FENSA, TrustMark and we are a member of the Ultraframe Ultra Installer network. Our quality was recognised at the G19 Awards where Leekes was named as a finalist for Installer of the Year and Sustainability Initiative of the Year.
