"Zen Windows advertises that they make things easy, and that they do. Zen windows doesn’t just make things easy, they have quality products, reasonable prices and exceptional service. We just had an entry door replaced and everyone we worked with was great. While they don’t push you into buying any products, they do go out of the way to help you make the right decisions. Everything went exactly as they told us, the installers were top notch and the finished product looks great. Without hesitation, we would highly recommend Zen Windows to anyone looking for doors or windows."

"Clifton Contracting made the whole process so easy from planning to completion. We are thrilled with the window and the complete change in our basement. We chose a larger Anderson window and an upgraded Rockwell window well. No other estimates could match them."

"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."

"Team from Power completed the work on time and cleaned up well after work was completed. Windows were measured correctly so replacement windows fit perfectly and were quality Pella windows versus no-name windows offered by other vendors."

"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."

"Well we signed the contract in October and we had to call in November to be scheduled after a deposit was taken. We were told that we would be contacted and we never were. We were finally scheduled the roofer came early Friday morning which I was happy about, the roofer started throwing trash in my elderly neighbors yard which ended up causing an argument between my neighbors and the roofers, things escalated and the police were called a police report was filed. My neighbor said he would sue if any damages were done to his property. The roofers left once it got dark outside, there was trash everywhere, they left my front yard gate and back yard gate open. They never told us they were leaving and they never told us when they were coming back. So the next morning around 10am I didn’t hear from the the roofers, I called the company and Mr.Whiting answered the phone, he said that he is sure his roofers would come back, I told him about the police report he said “the police can do what they need to do” he never apologized for the altercation or even asked what happened. He called back and told me the roofers were coming at 1pm, they didn’t arrive until after 3 pm. Then on top of everything my front bay windows slate wasn’t replaced with shingles because the roofers said it wasn’t completed in the estimate, which to me was a lie. But I will not be using this company ever again I was satisfied with the partial work that was completed I was not satisfied with the employees or owner. How do you not include a window in an estimate when I was told the window was included in the estimate, but my side bay window was. That’s very frustrating because this wasn’t cheap."
