Mountainview was great from start to finish. Zack gave really helpful information about our options. I really like that they deal with several suppliers and have personal experience with even more, so he could recommend the best product for us. I felt the whole way through as if I was being treated honestly and fairly. We had 10 windows replaced, so Zack and Alex were here at the house for a considerable amount of time. I felt very comfortable having them here - they were considerate, cleaned up very well after themselves, and considering the type of work that they had to do, were also quiet! The work was done really well and the windows look and feel great. I 100% recommend them, and will use them again.
