"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"Nova Exteriors did a fantastic job on our windows. Tom came to give us our estimate and walk us through the various products they provide. He did a great job at answering our questions and showing us what our options were without being in-your-face-buy-my-product sales guy. The team that came and installed the windows did an amazing job. They were in and out in half a day. We had five double hung windows installed and one massive picture window. They were courteous, on time, and cleaned up inside and outside when they were done."
