"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."

"Egress Windows Fairfax installed an egress window in my basement and did a fantastic job. The window permits emergency evacuation from a room being converted into a bedroom. The reasonable cost of the egress window immediately raised the value of my home. To minimize damage to my yard and my neighbor’s yard the company manually dug the pit for the egress window to below the foundation line and beneath the foundation drainage pipe. I was very surprised to see a large sump pump pit installed below the foundation. The contractor explained that they do this as a service in the event of any future drainage issues it is quick and low cost to install a sump pump. Small stones filled the bottom of the pit. The contractor offered several options for pre-fabricated surrounds to line the pit. Every member of the crew of Egress Windows Fairfax knew their job and worked diligently. They only rested during their lunch time. At the end of the second day the job was completed and the soil was well graded around the new egress window. This is a company with long term employees who take pride in their work and who strive to satisfy their customer. I highly recommend the company."

"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."

"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."

"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 was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"Brian and his crew at Unicorn are outstanding. They have redone my roof, doors, and windows. They are prompt, reliable, and want to make sure their customers are happy."

"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."
