"Zen windows was wonderful from start to finish. No hard sell, no deposit required, they kept in touch while we waited for the doors to be manufactured and delivered. The installers came on the scheduled day, on time, installed the doors, cleaned up and left. They were professional and friendly and my new doors are BEAUTIFUL!"

"Great experience! They got to me very fast. The service tech came to my house to give a quote and told me he could fix it on the spot if I wanted. I am moving so I needed the window fixed ASAP. About 30-45 minutes later new window! Looks great! I definitely recommend them."

"It was amazing. Before the work, it was amazing how little rain it would take to cause standing water in the yard. After they completed, we got 2" of rain in one day and had no standing water anywhere in the area they worked."

"Replaced all the screening on our patio and replaced the door to access the patio. Was reasonably priced and prompt in doing exactly what he said he would do. Would definitely hire him again to do other work around the house."

"They did a great job, cleaned everything up and it went well. It looks really good and I would highly recommend them. I will definitely hire them again."

"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."

"UNICORP recently replaced 29 windows, including 1 casement and 1 large sliding glass door at our residence. To say that were are pleased with the final product is a great understatement. The company owner, Brian, made the initial visit to our home and he is very personable, professional, highly knowledgeable and very passionate about the product he sells. The installation crew, led by Paul, was outstanding. They were highly skilled, attentive to the smallest detail, very easy to have in our home, AND did a great final cleanup. No trash or debris anywhere. The actual windows are amazing. High-quality, custom made, and reasonably priced. Particularly noteworthy is the significant reduction of outside noise. The screens are barely noticeable which makes for a big visual improvement. For higher cost projects we routinely obtain 3 estimates before moving forward. In this instance, we followed our gut, and went with the first company, Unicorp, cancelled appointments with 2 other companies. Not our usual approach, but our intuition served us well. If you're in the market for new windows you owe it to yourself to contact UNICORP and give them an opportunity to submit an estimate. I'm betting you won't regret it. David and Lauren"

"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."

"We have had NovaExteriors replace all our gutters, windows, sliding doors and front door over the last several years from the contractor grade products that the town house was built with. We have been very pleased with everything. They installed our steel front door about 10 years ago and we started to have issues with the deadbolt not aligning with the door jam and the rubber sweep wearing out over time. I contacted NovaExteriors, made my appointment and they arrived right on time and performed the needed maintenance that was required. The door is back to being perfect. Once again, we were very pleased with NovaExteriors, their prompt arrival and the quality of work. You can't go wrong with NovaExteriors."

"Excellent job in installing windows and bow window at my lovely home. It looks beautiful and we are very happy with the results. Thanks"
