This is a difficult review. The windows they installed seem very nice, and we are happy with them.

The salesman was good. Rebecca setting the appointment was good. Installation was ok. Where they fell apart was the contract. They were suppose to send rebate via electronically but instead the rebate gift cards were sent to the college rental house. The kicker was trying to get someone on the phone after the job is done was impossible. I think this will be the same for warranty work. They are MIA when they are needed. VERY DISAPPOINTING

Recently remodeled the shower tub combo in both bathrooms. Max and Jessica did an excellent job. They completed the job in 4 days and left the place spotless. Their workmanship and communication throughout was great. So far the smoothest experience we’ve ever had with any remodeling project. Thank you!
