At Coziluxe, we believe in turning a house into a home, a place should reflect you and your lifestyle. With industrial experience of over 18 years, it gives you the peace of mind that you are dealing with a company large enough to be competitive but small enough to give you that personal service you expect when replacing Windows, Doors and Conservatories. Coziluxe is an honest and hard-working company that provides customers with a high-quality product without the expensive price tag.
Planning permission isn’t required for most single storey house extensions. If it is though, we organise permissions and complete planning applications, taking on the hassle so you don’t have to. It’s all included in your quote.
We're here to help every step of the way when it comes to choosing windows, doors, and roofing for your extension. Our design consultant will visit your home to discuss your plans and best use of your new space.
We provide a 10-year insurance-backed guarantee for the windows and doors of your extension. These products also come with a 15-year guarantee for sealed glass units. If you sell your home, you can transfer the guarantees to the new owner.
We create, or extrude, our own uPVC window frames for our stormproof casement and tilt & turn windows at our Norwich factory. Making our own uPVC frames means we have complete control over their quality from start to finish.
