Bi-folding doors can be configured with 2 to 7 panels, folding to the left, right, or both sides depending on the aperture.

Fantastic experience with Lee from Range Windows. Prompt efficient service, windows swiftly measured up and date of installation agreed. Call on the day of installation to confirm the time and Lee arrived as agreed. Fab installation and exceptionally happy with the product. Will definitely recommend.

Had a new door fitted by Range Windows and Doors today, door looks amazing and service was brilliant. Everything was all cleaned up after the job was finished too which was a bonus. Highly recommended.

Definitely recommend this company! Service is 5 star, they try to help any way they can. Fitting me in to fit a low profile door so my wheelchair could get in my new home. The door is easy to work, draft free and feels very secure and solid. A very caring genuine company which is hard to find nowadays.

Adam and Brad came early, on time and got to work straight away. They worked hard, fitting 3 new bedroom windows then a back door — all finished in the day. Every item was installed well. They cleaned up everything inside and out, taking all rubbish away with them. Thank you for your good work.

Within a day Adam came to the house for a free quote — no pressure, no rush. Very professional and we chose this company just from how Adam represented them. Lee measured everything up within days, giving honest advice where other companies were saying to replace everything. Outstanding service.

I couldn't recommend these guys enough! Service was spot on start to finish. Lee and the guys are so knowledgeable about their products, even dropping off brochures so I could make a decision in my own time. No pressured sales, just down to earth people. Adam and Brad fitted the door — so professional.
