"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."

"From the quote to the completion of the installation, we were very happy that we chose Unicorp. We did a full (28 windows) window replacement and 1 exterior and storm door replacement. The windows are the Prodigy by Uncorp windows and they are beautiful and well-made, and the price was more than competitive with the other quotes we received. Our house is 100 years old and still had the original windows, so it was a very challenging and lengthy installation, but their installer did an excellent and very thorough job. We plan on using Unicorp again in the future when we replace our remaining exterior doors."

"Nova Exteriors recently replaced our 43-year-old patio door, which was in terrible shape, with a ProVia Endure door. Nova's representative, Sam Osta, arrived on time, gave us a thorough explanation of why ProVia's Endure door would work well in our home, stayed as long as we had questions, and didn't try to upsell us on "bells and whistles" we didn't need. Nova's crew did an excellent job of installing the door, working efficiently and cleaning up when finished. Now that we've used the door many times since the installation, we can attest to its ease of use, especially the dead-bolt safety feature at the door's bottom that operates with an easy touch of a shoe. And it looks beautiful as well. We highly recommend Sam Osta and Nova Exteriors for patio door replacement."

"Their Handyman Nestor Ramirez came my house within two hours after I contacted Chapin Handyman LLC; and it took him less than 30 minutes to locate and clear away the obstructions preventing my upper window from closing completely."
