The Perfect Timber Replacement

The flush casement windows we install are the perfect replacement for old timber windows in your Cardiff home. Unlike timber, the uPVC windows we offer don’t provide any high maintenance headaches, retaining year after year of great use. We fit flush sash windows that will continue to retain their quality, even after constant exposure to the changeable Cardiff weather.

Our Cardiff customers can have complete peace of mind they’ve invested in the best flush casement windows for their home by using Leekes. The flush sash windows we install are accompanied by a guarantee of quality. Even after regular exposure to the changeable Cardiff weather, the frame of the window won’t flake, bow, crack, discolour or twist, and the colour has been imbued into the frame. This eliminates the need to repaint the window, with the only maintenance you’ll need to carry out is wiping the window down with a damp cloth, maintaining the good-as-new look for years to come.

Benefits of Our Flush Casement Window Range


You’ll do your bit for the environment by choosing our flush casement windows for your Cardiff home. Our flush sash windows are manufactured to achieve U-values as low as 1.3 W/m2K, with the uPVC frame boasting better thermal capabilities than timber. We offer these uPVC windows with double glazing as standard and triple glazing options also available.

The multi-chambered uPVC frame works alongside the glazing panes, trapping pockets of warm air within your Cardiff home. By choosing our flush casement windows, you’ll reduce your dependency upon your central heating, freeing up money for you to spend on the things you want and need. This will mean the overall carbon footprint of your home will shrink.


The overall security of your Cardiff home is something Leekes takes seriously. That’s why we offer flush casement windows that will protect your South Wales property against modern burglary methods. The multi-chambered uPVC frame offers an excellent level of strength and rigidity. When this is combined with the glazing panes and multi-point locking, it will create a high level of security across the frame, removing any potential weak spots that could be exploited.

For Cardiff customers looking to increase the security of our uPVC Flush Casement Windows further, we provide the perfect upgrade. The market-leading Yale lock can be added to the design of our uPVC sash windows. The locks are accompanied by a lifetime guarantee, offering unwavering protection for your family.


The flush casement windows we install have weatherseals fitted across the frame. These weatherseals work alongside the panes of glazing and the frame, eliminating cold draughts and dampness that could disrupt the overall comfort of your Cardiff home. This will remove the risk of dampness and cold draughts, with the trickle vents carrying standing water away from your South Wales home.

Even after constant exposure to the changeable South Wales weather, our uPVC Flush Casement WIndows will maintain their quality. This means our Cardiff customers will not be left facing the same high maintenance problems that plagued old timber sash designs. Even in the very worst weather, our uPVC flush sash windows will keep the bad weather out of your home.


By investing in Leekes’ Flush Casement Windows for your Cardiff home, you can have complete confidence that you’ve invested in the best window for your home. Our uPVC windows are fully accredited and designed in line with the latest building regulations and created to PAS24 standards. This provides you with the peace of mind that you’re getting the best window for your home.

Leekes is accredited by the likes of FENSA, TrustMark, as well as a member of the Ultraframe Ultra Installer network. We were recognised in the G19 awards, named as a finalist for Installer of the Year and Sustainability Initiative of the Year. Accreditations are something we hold with great pride as an installer, and we hope it gives our South Wales customers peace of mind to press ahead with an installation of our flush casement windows.
