We are proud to offer our award winning flush windows to improve homes in and around London. Flush windows are categorised by sitting within the frame for a smooth finish. This means that there are no unsightly lines and comes with a clean look. Add value to any London property with our flush windows.

Using the highest quality uPVC, the windows excel in thermal retention, durability and security. They are also noise reducing and are incredibly low maintenance. Using modern manufacturing techniques, we ensure the windows will last for decades to come. As a result, homeowners can make a worthwhile investment.

Whether the occupying lives in a Heritage, period, listed building or modern property, the flush windows can add a unique look. They offer a timeless, elegant appearance, replicating the look of traditional timber. However, they are expertly manufactured from unrivalled uPVC.


It’s essential that London homeowners feel as safe as possible. That’s why we manufacture our flush windows with highly secure locking systems. The multi-point locking helps to prevent unwanted access, with the locks tested on their resilience to force. This will give customers total peace of mind that their home, family and possessions are safe behind our windows.

Thermally Efficient

When comparing wood or aluminium, uPVC is an incredibly thermally efficient material. It can help to better insulate the property by preventing heat loss. Each window is designed with double glazing as an insulating profile to help lower how much heat can escape. This means that the customer can considerably lower their energy bills and reduce their carbon footprint.

Weather Resistant

With a multi-chambered profile, the windows excel in keeping cold draughts out of the property. This means that the house will stay at the optimum temperature all year round. The windows all work to prevent water ingress, which is perfect for the unpredictable British weather. With high performance uPVC, you can enjoy years of usage through every season.

Low Maintenance

uPVC is a popular choice for homeowners as it is incredibly low maintenance. The flush windows won’t warp, crack, rot or distort, even when exposed to the elements. To keep the products looking and performing at a high standard, homeowners simple have to wipe them down with a damp cloth every so often. Improve any home in London and make a worthwhile investment.
