MasterShield did a great job, performed the work on schedule and it looks great. They hauled away the old windows and cleaned up nicely, including cleaning the glass on all the new windows. The work was done in one day, as promised. The guys who did the work were very nice and answered all of our questions. I would strongly recommend Master Shield, and would certainly use their services again. I should also mention that the window style/manufacturer that we needed, to match our other windows, was no longer being sold on the east coast. MasterShield contacted the manufacturer and made special arrangements to get them produced and shipped. We used MasterShield a few years ago to install gutter guards too, and were very happy with that work also.
