The Perfect Timber Replacement

Flush casement windows can make any home in Mwyndy warmer, brighter and safer. These uPVC windows are classic designs with modern materials, meaning they are much easier to maintain than old wooden ones and last for years longer. Not only that, you can benefit from improved insulation, security and even weatherproofing. And, with Leekes, you have the chance to create bespoke windows for your home!

With our uPVC flush casement windows, you can customise your design to suit your home in Mwyndy seamlessly. You can choose woodgrain foils for a classic look or opt for bold colours to create a modern contrast. No matter the choice, our options won’t fade or discolour for years to come. Our uPVC flush casement windows are guaranteed to stand the test of time for your home in Mwyndy!

Benefits of Our Flush Casement Window Range


By installing flush casement windows in Mwyndy, you can make savings on your bills. With uPVC profiles as opposed to timber, our flush windows have better insulation than older designs. Not only that, you can choose either double or triple glazing for your windows, creating a thermal barrier for your home.

As a result, the multi-chambered uPVC profiles are able to keep more heat inside your home. That means our flush casement windows achieve U-values of 1.3W/m2K in Mwyndy, and they’re air and water-tight for even better insulation. That way, you can stay warm and save money on your energy bills!


Leekes is a company that takes your security seriously. Our flush casement windows prove that, as our designs come with advanced security hardware as standard. The profiles and glazing in our designs are sturdy and resilient, and the glass is reinforced for added strength and toughness.

However, there’s more to our windows than meets the eye. Underneath the strong design is a range of advanced features, including multi-point locking mechanisms that engage across the frame to prevent weak spots. Our windows can even come with the Yale lock, a design so secure it has a lifetime guarantee.


Our flush casement windows are the ideal replacement for old timber designs in your Mwyndy home. While timber struggles in bad weather, leading to more maintenance, uPVC windows have no issues. Our designs have advanced weatherseals as standard, and trickle vents will redirect standing water.

Because our flush casement windows are weatherproof, they’re more durable than wooden windows as well. You can be sure that your windows will last for decades, and that’s without any warping, cracking or fading. As a result, you won’t need to maintain these windows regularly!


By choosing Leekes, you can pick out your ideal flush casement windows in Mwyndy with confidence. As a local installer in Rhondda Cynon Taff, we’re proud to help our customers get market-leading uPVC windows for their homes. Our windows meet PAS24 security standards, and they exceed UK Building Regulations, too.

It’s one of the reasons why Leekes is accredited by a range of leading bodies. We have accreditations from FENSA and TrustMark, and we’re proud to be long-standing members of the Ultraframe Ultra Installer network. We’ve even been a nominated finalist at the G19 awards!
