This is the third time we have used Morden UPVC windows. Again, the windows arrived on time as advised. The delivery man was very helpful and placed the windows in the hall way as they were too heavy for me to carry. The windows are well made and exactly the right size as ordered. From previous orders we know that the windows are easy to fit and look amazing when finished. We spent ten years not being able to clean the outside of our old windows, now it is quick, simple and safe. Modern UPVC windows website is the best I have used. It is simple and easy, especially the video about measuring. It asks you questions about your choices and checks on those that clearly people find difficult. I have always been confident that my order is the one I want. Thank you.
