"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."

"Excellent work. Fixed my windows with failed seals for a reasonable price and with quality workmanship. Professional and punctual."

"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."

"The customer service before the installation was outstanding - very attentive to detail, product knowledge was exceptional, and no high pressure sales.  Max went out of his way to bring full size samples of the siding to ensure that we were pleased with the quality and colors.  We felt like we were provide the best price initially - no back and forth negotiations were needed.  During and after the installation, the customer service and responsiveness remained outstanding.  The crew were professional, pleasant and did an excellent job. The few corrections that were needed were handled immediately and professionally.   We are complete satisfied with our purchase and would definitely do business with Fox Creek again and recommend them to others.

"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!"

"We were extremely pleased with the 20 new windows we just had installed by Pawel at Unicorp. The installation was very professional, they cleaned up each day and were very easy to have at the house. Brian Weil, the owner went above & beyond explaining the different types of windows, ultimately we wanted the look of the 1964 windows we were replacing with grilles on the inside & outside but just more efficient. We are very pleased with the end product. Both Brian and Pawel were very patient with me and the questions I had. I highly recommend calling Unicorp should you need new windows."

"At first I was extremely apprehensive about buying all new windows for my home from one vendor all at once. Because, I was completely burned in the past from a previous contractor and they installed a few of my windows about 3 years ago and didnâ t complete the job, it was a horrible experience and left a very negative feeling regarding purchasing windows from anyone in the future with the fear of being taken advantage of again. However, after analyzing and getting great descriptions of the windows and the installation process, I found it worth taking the chance and in my best interest to have ARHT Home Solutions do the work for me. His workforce was very professional and I was very satisfied with my new windows. I have decided also to use ARHT to install a new front door and storm door after the completion of the new windows that were installed. They showed up on time and was very patient with me, the work ethic was great through the entire process and am completely satisfied."

"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 got a number of bids from a variety of contractors. I'm glad we selected Premier. We fully replaced a couple of windows and just replaced the glass on a number of others. They do both things really well. The work crews are courteous, professional, and do high-quality work. They also left the house really clean, which we appreciate."
