What I liked right away was…read morehow casual and easy everything felt, no pushy sales tactics, just straightforward and friendly communication. They were super responsive anytime I reached out with questions. Emails and calls were returned quickly, which made the whole process feel smooth and stress-free. They also got someone out pretty fast to measure the windows, so things kept moving without delays. I ordered 10 windows for my townhouse at the end of February, and everything stayed on track. The windows came in April, and installation was set up for the very next week, exactly how they said it would go. The install team (two guys, led by the amazing Mark) was awesome, very professional, worked efficiently, and took the time to protect my floors and furniture. They cleaned up as they went, which I definitely appreciated. Scott, the owner, stayed in touch throughout the day of installation and honestly throughout the whole process. I had a couple of window and sash issues but Scott was amazing and the kind of communication and follow-through really stood out. Overall, I couldn't be happier with the experience. They did exactly what they said they would do, and the customer service was top-notch. I'd definitely recommend ZEN Windows to anyone. It really was a calm, "ZEN-like" experience. Haha!!

Yep, another five star review for American Windows…read more We received three estimates for replacing three windows, a French door and a picture window. American Window undercut the estimates of the other two vendors by a substantial margin. We also really liked they only asked for a modest down payment. Jay was our sales contact at American Windows and he was absolutely great. He has an engaging personality, and kept all his commitments to us. We appreciated that when installation day came, he swung by to ensure all was going well. Oh, how did the installation go? It was fantastic. Not only did the windows and door come earlier than promised, the American Windows crew came on time and worked quickly and professionally. We were amazed that the whole job only took 4 1/2 hours to complete. The windows and door materials are high quality and we are very satisfied with the results.

We decided to drive an hour out to their showroom without calling first. Even though they weren't open yet and are by-appointment-only, Phil greeted us without hesitation.It turned out they couldn't take on our small window sill repair since they didn't install the original window, but Phil helped us anyway! He gave us repair ideas, explained potential causes, pointed us toward the right tools, and gave us contacts who could help. To top it off, his cuddly dog Wilson kept us company, and Phil even recommended a local spot for lunch since he knew we had a long drive. We are completely speechless at his kindness and support, despite not even being paying customers. Based on this first impression, we would work with Phil any day. The world needs more people like him!

They got my new door set with side windows in without me even needing to touch up any of the wall paint around it = amazing. The price was very reasonable. The preinstall communication was great. I added a few upgrades along the way and they were helpful and explained everything along the way. I highly recommend their service!

They did a great job a year ago and the door has a double lifetime warranty (so it also covers the next homeowner). Our door had a small defect a year after installation and Home Exteriors quickly completed a new door replacement. No hassle, negotiating, or any convincing. Just saw our photos and scheduled a new door installation. Their employee Luis is amazing! He showed us the new door first, to avoid installing one that was not satisfactory. Then promptly replaced the old one and professionally cleaned up afterwards. Home Exteriors Energy Consultants should be your "go to" choice for Home improvements!

However, the sales associate missed a few details and later tried to encourage us to pay more, although the contract was ratified. We refused and were prepared to cancel the order. He later came back to say that his boss assumed the additional fee. We were promised the door in 4-6 weeks, but it has now been several months. We received an email that the door would arrive at their warehouse by 2/26/26, yet as of today 2/28, there has been NO communication. If the door is installed, I'll update the status on the installation and quality of the door. At present, I'm not certain that I would recommend American Windows.
