    Worst windows!!!! Super disappointed and extremely frustrated! We have been dealing with this problem for way to long and nothing has been done to render the situation.

    The old backdoor was, kind of, a joke, because it didn't really close and cold wind could come in…read moreeasily and one could clearly see that was extremely outdated. I contacted "American Thermal Window Products" and wanted to get this house project rolling before 2022 came. Unfortunately, due to labor and material shortages, I was informed the door installation would be at least a three-month wait. Hey, that wasn't the company's fault and I always received a good service and prompt responses from the office. Nick was assigned to get in touch with me for an estimate. Nick and everyone else in the office were very friendly. Nick explained everything about the estimate (free in-person estimate) and answered any questions we had. He emphasized that everyone involving with the installation process worked for the company. With that being said, there would be no third party contractors hired off the street! I understood the virtue of using the company employees. I have been part of the gig economy for some times. I wouldn't say the contractors wouldn't do a job, yet there could be a lack of accountability on their part of work certainly. In late February 2022, I received a voicemail from Linda and immediately called the office. She scheduled the installation date for me and provided an arrival window. The crew came in prepared within the window and was ready to work! The installation was rather quick. The cleaning was thorough. Everything was painless. The crew leader told us that adjustment could be made if there was a need. That door...let me tell ya...was a godsent. It helped conserve the heat. It did have an energy-star icon, for those who are into the energy-efficient appliances. It is also esthetically pleasing. Overall, I'm very satisfied. I'm going to inspect the windows for the rest of the house and to see if I can get "American Thermal Window Products" involved again.

    Ordered new entry way doors from them because we had ordered metal screen doors from them years…read moreago, and we were pleased. The whole experience has been a nightmare. We ordered new doors for our house including a new front door. Following installation, the front door was snapping and popping when the sun hit it, and started to fade and paint was flecking off. We called to have it replaced because it was under warranty. They replaced it with a door that looked worse. You could see the unpainted inside window trim thru the windows. We went back and forth, requesting our money back, but we were not able to make any progress other than they would order a new door for us. This took months, many phone calls with service and general manager. Finally they said they had 2 doors for us, and that we could pick. It's not lost on us that if we picked between the 2 doors, that then they could come back to us and say, "you picked it". One of the doors had sand inside the windows-clumps of sand. The other one looked better, but it was obvious that it was the first door that we had returned, just painted. We were done! This company has gone down hill since we ordered from them back in 2020. Avoid them at all costs. They are sneaky and don't have good customer service. Nor do they have effective management.
