Workmanship was mediocre - they had to return to fix up one window that was done very poorly. Other ones that they did, the work was not so good at all. Some weeks later, when I phoned them for a problem - because one window wouldn't open - they were very defensive on the phone, borderline rude; and said someone would phone us back. In the meanwhile, we had sold the house. Over three months later, someone did phone and said what was the problem three months ago?! I told her 3 months was too long a time for any reputable company to return their customer's call!! She didn't care. Just thought to share this with others ... we would definitely not use them again, ever.
