Low Maintenance

At Infinite Windows, we supply and install solutions built to last. Our triple glazed doors will be a long term investment in your Leighton Buzzard home so that you can enjoy them for many years. Our Internorm composite doors and aluminium profiles are ideal entrance doors. 

Once installed, all you will have to do is to wipe them down occasionally, and they will be clean and fresh looking as the day they were installed. Aluminium and uPVC are sturdy building materials and do not absorb any moisture, so your new doors will not rot, flake, bow, or crack, unlike timber doors.

Thermal Efficiency

As the cost of living continues to rise in the UK, think about investing in energy efficient and durable solutions. Our triple glazed doors are made of three strong glass panes separated by a small vacuum filled with an inert gas like argon. This expertly engineered design makes these doors extremely thermally efficient as they lock the heat inside and reflect the warmth into your home for a comfortable and cosy interior. 

Our Leighton Buzzard homeowners can keep their homes naturally warm and reduce their energy consumption, saving money on bills. Even in the coldest months, your family and friends will be comfortable in your lovely home.

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.

We highly recommend Infinite Windows & Doors as they are true professionals unlike some of the cowboys we have dealt with in the past. Thank you again.

C. Colucci

Excellent company all round. The service we received from Colin and Jacky was 2nd to none from start to finish. They have a super showroom in Milton Keynes and they displayed such a genuine interest in our project accompanied too, by their ample product knowledge which helped assist with our designs

We can thoroughly recommend them.
