I had researched sliding doors extensively and I felt the XP Panoramic Slide doors really gave value for money and were comparable to products at the higher end of the market. However when I read some of the negative reviews I was apprehensive about placing my order. I am delighted to say the whole experience has been fantastic from point of sale to installation. Express Bifolds delivered my doors within the short lead time I had and worked closely with my builders to ensure the preparation for the opening was correct. The installation went very smoothly and the windows look amazing. I would highly recommend Express Bifolds without any reservations.
