Total Replacement of Windows and Frames (unit) for Upstairs Back of the house. “Andy was meticulous re his visits to measure and discuss the best possible options. Took time to explain the different types of windows that could be fitted and placement of said windows. He worked solidly with his colleague to take down the old unit and replace with new unit in a very long day to ensure that the base was ready to work on the next couple of days. Attention to detail was excellent and needed to work through some tricky unexpected issues. Solid, reliable and efficient team. They cleaned up after them each day. Conscientious and a pleasure to deal with. Highly recommended will use again”
