What Do Our Customers Say?

Excellent and prompt service from Infinite Windows & Doors when we opted to use them to provide our bifold doors. The builder who is building our extension failed to sort them through his “usual” window company so we cast out on our own and found Infinite. I’m very glad we did. The doors arrived earlier than expected, and were fitted in the course of an afternoon. They look fabulous and will look even better when the rest of the extension build is completed!

S. Thomas

Amazing knowledge from the salesperson, great clarity of documentation, customer service, installation and quality of products. Highly recommend. So refreshing to deal with a professional, approachable Company who practice integrity.

W. Rust

From start to finish we have been impressed by the professionalism and enthusiasm of the team at Infinite Windows & Doors Ltd. Their price was competitive. They worked quickly, neatly and efficiently and the standard of finish was excellent. Everyone was polite and friendly and we can highly recommend them.

E. Chua

Colin, Jamie and Jackie are a great team and a joy to work with. I introduce all my clients to them, knowing they will receive one to one attention throughout the whole process. They know their products inside out from pricing, technically to fitting on site. They work with the Architect throughout the process, providing CAD details. They work to ensure that the process is as simple and efficient as possible.
