Every Nine Zero project begins with careful consultation and precise measurement. Our windows and doors are designed specifically for each property, ensuring an exact fit and a finish that complements the building’s architecture.
We use FSC-certified timber alongside high-performance glazing systems, combining traditional joinery techniques with modern manufacturing capabilities. We manufacture in Cornwall with our skilled joiners maintaining consistent quality and attention to detail.
Our windows and doors are supported by robust guarantees, providing long-term reassurance to you and your clients.

Modern performance is essential for properties across the capital, which is why Nine Zero windows are available with a range of glass and glazing options, providing improved thermal efficiency, reduced noise transmission, and enhanced security. These solutions are designed to integrate seamlessly with traditional timber frames, making them suitable for both Heritage properties and new developments. Our slim-profile options can help preserve original aesthetics, while our sustainable timber frames and double glazing ensure energy efficiency and comfort.
For listed buildings and conservation areas, we take a considered approach to glazing specification, ensuring compliance with planning requirements while delivering meaningful performance improvements wherever permitted.
Paint and finish options
We offer a wide range of high-quality paint and finish options, allowing complete flexibility across both Heritage and contemporary projects. From classic colours suited to Victorian and period homes to modern, understated tones for new developments, our finishes are designed to fully meet your needs.

Our windows and doors are designed to perform across a wide range of project types. For Heritage homes, we understand conservation requirements and the importance of visual authenticity.
