The Perfect Timber Replacement

Our flush casement windows are a fantastic option for homeowners in Llanelli. Flush casement windows are a part of our range of uPVC windows, and our designs outperform ones with wooden profiles. Because of this, they’re easier to maintain, are more efficient over time, and they can make your home more secure. You can also be sure they’ll withstand the worst weather conditions you’ll face in South Wales.

Also, you can customise our flush casement windows to suit your home in Llanelli seamlessly. You can choose classic woodgrain foils for a traditional look or bold colours for a modern one. Not only that, you can be sure your selection will keep shining for decades with our durable uPVC flush casement windows. Get a window that stands the test of time in South Wales today!

Benefits of Our Flush Casement Window Range


With our flush casement windows, you can save money in Llanelli. We install designs that have multi-chambered uPVC profiles, meaning that your window will have better insulation across the board. As a result, they can achieve U-values as low as 1.3W/m2K, making them some of the best flush sash windows around.

You can also install our flush windows with double or triple glazing, improving the heat you retain in your home. And, with air and water-tight profiles, you’ll prevent draughts or damp spots from developing. That way, you can make your home warmer while making your energy bills cheaper!


At Leekes, we take the security of your home seriously. It’s why our flush casement windows are among the most secure windows you can invest in for your home in Llanelli. Our windows have reinforced profiles and glazing, making them robust and durable enough to keep you and your family safe.

Burglars and intruders won’t find a way through your windows thanks to the advanced security hardware in the design. We install multi-point locking mechanisms across the design, and we offer the outstanding Yale lock. This lock has a lifetime guarantee, and you’ll have peace of mind for nearly as long.


Our flush casement windows will also protect you from bad weather in Llanelli. As we use uPVC profiles rather than timber in our windows, you can benefit from a more durable, weatherproof design. Our windows feature weatherseals that prevent draughts and trickle vents that redirect standing water away.

Along with the uPVC profiles, that means your window will have no issue in any conditions. Your windows won’t crack, twist, bow or discolour, and they won’t need any regular maintenance to look or perform at their best. That way, you can make your flush sash windows last for decades to come in Llanelli!


At Leekes, we only install flush casement windows in Llanelli that meet our high standards. Because of this, the uPVC flush sash windows we fit are market-leading and meet all the relevant standards. Our windows are PAS24-approved and they exceed the requirements set by UK Building Regulations.

This commitment to quality is what has made Leekes one of South Wales’ most trusted double glazing installers. We have accreditations from FENSA and TrustMark, and we’re also one of the companies in the Ultraframe Ultra Installer network. We’ve been nominated as a finalist at the G19 awards, too!
