What was most impressive to us was their adherence to schedule and following through exactly as they said they would from first bid, through ordering, delivery, installation, finishing outside trim, clean-up etc. Also impressive was the comfort level of working with them. We are two women raising a child and did not feel any negative judgement on their part. They both were hard workers, even on very hot days, and took the time needed to do a thorough job. All our windows work perfectly. They spread tarps on the stairs and throughout the house when hauling debris out and tidied up after themselves every day. They did make some gouges in new vinyl flooring in basement. I wish I had laid cardboard or rugs down beforehand but in general, we were very happy with their work and the fact that they followed through in a timely manner. Brian was good at answering questions via e-mail when we sent them and they were easy to be around. We would certainly hire either one of them next time.
