The company offered reasonable rates and helped secure reasonable financing. Victor and his crew did outstanding work siding our house. Victor worked with us to determine best options for moulding and flashing placement with some very challenging areas in the front of the house. Entire exterior was thoroughly caulked.

From initial consultation, to coordinating installation, to final walk through- we highly recommend New Windows for America. This company was a delight to work with, and the process was so smooth. We loved working with Kevin, Julie, and the entire installation team. We felt like valued customers, and would 10/10 recommend to anyone needing residential (us) or commercial window installation. They replaced 12 old windows, and it brought such a facelift to our home. Such a pleasure from start to finish working with Windows for America!

I had an exceptional experience with New Window for America. From the first phone call to the installation of my new windows. This company exceeded my expectations on pricing, quality of the product and customer service. I plan to do future business with New Windows for America and would refer them to anyone in the market for new windows.

I had a great experience getting my windows installed and appreciated the skills and expertise of the crew who worked with my plantation shutters and got everything done in a timely manner and with no issues. These guys know what they're doing and came prepared with three guys for a heavy job. I will definitely recommend them to my neighbors.

We had a terrific experience working with New Windows for America. A recent hail storm broke some windows and shredded our screens. Clyde came out immediately and was very knowledgeable and attentive to our needs. The windows we purchased were more affordable than we though possible. They provided outstanding service and their attention to detail was unmatched. Simply the easiest home fix it project we've ever done. Plus our new windows look fantastic! Thank you Clyde.

My experience started 20 years ago.They installed windows for me. All was wonderful and still is. In 2014 I need some pins to be replaced due to weather etc they came out replaced & did some caulking at No charge Now moving forward 2023 some of the corners & more pins were broke working with Monica in office, my corners were replaced& new pins & rescreend. The same gentleman that came out in 2014 is the same person who did the work he and his accociate came to install and again no Charge. Excellent work & professional I would HIGHLY recomed them. Hard to find such service in this day & age
