What types of windows do you offer?
We offer a variety of window styles including casement, tilt and turn, and sliding sash windows, all designed to perfectly complement any property style.
What materials are available for your windows?
Our windows come in uPVC as standard, providing both durability and style. We also supply aluminium windows if that is your preference. Speak to a member of our team who will be happy to help find the perfect fit for your home.

What is the energy efficiency of your windows?
Our windows are designed with advanced insulation technology to maximise energy efficiency and reduce heating costs. As standard, our windows achieve a 1.2 U-Value, using uPVC Thermal Inserts and Thermal Glass with ClimaGuard® A+ (CE). ClimaGuard® A+ is designed to allow solar heat to pass through and be retained within the building by the low-E coating.
What is included in your installation service?
Our installation service includes a comprehensive survey, professional fitting, and a thorough clean-up, ensuring a seamless experience.
Can I add Georgian Bars to my windows?
Yes, this is easily achieved. Let us know the number per pane and we will have these added to the inside of the double glazed unit so that they never need cleaned. This adds a classic look to your windows.
