Because it is a big project, I actually contacted at least 7-8 companies for quotes and ended up using American windows because of their best price and the best windows brand and glass package. Energy efficiency was my priority so I want the best price and best windows which seems to be very hard. But Jay (the project manager) made sure I got what I wanted. The team went out to install 40 windows and they absolutely did an excellent job. They were super friendly and professional. I'm very neat and detailed so they made sure all windows are cleaned and properly installed. After installing, they vacuumed and even mopped the floor for me. I'm very pleased with their work !

Amazing experience from start to finish! We recently had American Windows replace all the windows…read morein our house and it could not have had a better experience from end to end. Ben was our point of contact throughout the entire project. He came out to take the initial measurements, talk through the project, and generate a quote. It was a complete zero-pressure experience. After receiving the quote I made an appointment to visit the showroom (though Ben also offered to bring some window samples to the house). We really liked the windows (Sunrise Restorations) and moved forward with the project. The installation went flawless! I'm a bit of a perfectionist and usually have to stop myself from nitpicking on small little flaws from general contractors, but American Windows did such a stellar job I couldn't find a single flaw in their work. I'm very happy I went with them!

Keith got back to me very quickly, was knowledgeable about the products, and offered competitive pricing. He took the time to understand the unique qualities of my roof to ensure that everything would be taken care of perfectly. Once the permit came through, he was able to get his team out quickly and they did a great job installing the roof (done in a day!) Keith and his crew were professional, timely, and kind. When a small flashing issue popped up several months later, Keith sent a team out to fix it ASAP. I would recommend this company to anyone looking for great service and quality. I'm going to be reaching out for a new security door soon!

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!!

We were impressed by the reviews Seneca Creek had gotten and decided to give them a try when we learned that they had experience installing EcoStar, a slate look-a-like shingle. I was further impressed by project manager Tim Bissell's attention to detail in the planning and his ability to reply to our calls almost immediately. The project also included re-siding four dormers, not to mention the removal of existing 150 year-old slate as well as some 30 year-old-asphalt shingles. The siding team came first and were here four days. They came early and worked constantly all day and stayed late to cleanup - not leaving until dark. Then came the roofing team. They, soo, arrived before starting time and did not leave until it was nearly dark. They were here a week and all that time kept the yard picked up, neat and orderly after the end of each day. I would definitely recommend Seneca Creek if you are interviewing roofing and/or siding companies. In 50 years (EcoStar has a 50 year warranty!) I will call them again myself!

Tim explained the work and set reasonable expectations and I thank him for that. I would gladly recommend Seneca Creek to a friend or neighbor.

For the first time I realize I had been hearing a fair amount of outside noise (which I'd apparently gotten used to), because these windows/doors are soundproof; now I don't hear anything at all from outside! And even better, the windows are easy to open, and my sliding glass doors actually slide well in the track, and are not shaking and drafty when it's windy outside -- major improvements from my old, builder-grade, 20+ year-old windows/sliding door. Further, the service crew was excellent -- careful, kind, professional, efficient, and they cleaned up everything afterwards. Roger, the foreman, has been doing this work for almost 30 years, and Jose, who single-handedly carried in/out the windows/doors, has been doing this work for 10+ years. I didn't get the name of the quiet third service person who was mostly outside and on the ladders, also very efficient. fyi, they did mention that working on the 4th floor of our condos from ladders was a bit more challenging as the original builder-grade windows had been made to fit by being packed/taped in place from the outside, which necessitated them having to actually break some of the glass to be able to pull the old windows out. But they did it - and did it well. Finally, Shaun, the project manager who gave me my estimate and oversaw the project from estimate, HOA approval process, to completion, was great. Highly recommended.

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.
