I just wanted to say a huge thank you to your installers. Adam and his colleague (I’m afraid I forgot his name) worked non-stop from the time they got here until the time they left and they were so polite and helpful, they have done an amazing job fitting the windows and the external finish is excellent. I have had a lot of experience with different trades people over the last few years and it’s rare to find such professional people with such attention to detail! The windows themselves also great quality and we are very happy with them. Thanks again.
