What Our Customers Have Been Saying

Totally fantastic experience from start to finish. Very friendly people with quick response times, very efficient and very professional. Can’t thank them enough for helping with the acoustic window replacement. Highly recommend.

Customer in Northamptonshire

Just had my old wooden framed conservatory and sliding patio door upgraded to UPVC from these guys. I cannot recommend them enough! The service was great from the initial phone enquiry right up to completion, they were very informative about material availability and timescale. Prompt arrival every morning they were here and very tidy. The quality of the new conservatory is great and my family and I are looking forward to using it in the summer now.

Customer in Northamptonshire

Outstanding service. We had all of our windows and doors replaced in our home and Windsor did this without making any mess at all. The windows themselves are of great quality and so was the professionalism and friendly manner of Lee. Would recommend without any hesitation. Thank you, Windsor.

Customer in Northamptonshire

The whole process of choosing, fitting and buying my new front door was handled in a professional, friendly and efficient manner. I wouldn’t hesitate to recommend or use Windsor Windows again. Coupled with this was the fact that my door was not as expensive as those at lower rated companies! Wow 🙂 Thank you for a great service.
