"Bottom Line: If customer service, especially years after installation, matters to you, then you NEED to work with this company. In 2018, we had new Provia external doors installed for our entryway and garage. After 8 years, the door sweeps were beginning to wear, and unfortunately, the original installer had retired his business. I was uncertain who exactly should handle the replacement in this case. As a long shot, I contacted Zen Windows who installed a Provia patio door for us in 2025. They sent out a technician who honored Provia’s warranty on our 2018 doors, replaced the sweeps, and realigned the doors as well. In a world of truly lackluster customer support, Zen Windows stands out as truly great. You will not find a better company."

"They offered a couple of options to fix our broken window. Mr Boston was very pleasant to work on. The worker arrived on time and did the work as promised."

"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."

"Global Home Solutions installed a wood screen door to replace an older door. Our home is 45 years old and accommodations had to be made. The technician did a good job adjusting to the situation."

"Fox Creek Buillders did a great job taking off my old wood siding, replacing multiple rotten window sills outside, wrapping all wood around windows, installing new gutters. Couldn’t be happier with the finished project. Max was great to deal with and helped me so much picking out the siding. Juan and his workers worked so hard and were always there on time. I would definitely recommend them!!!"

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

"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."

"I contacted Eddie on Wednesday and the repair was done by Friday. He offered to come out same day but that didn't work in my schedule. He was prompt and friendly and was able to get the job done in a very timely manner even with a little curveball thrown in. I would definitely use Eddie again!"

"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."

"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs to have a window fixed or replaced."
