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!

After requesting an updated estimate( since the one they sent me had the wrong color) and asking for the door color to be changed to white, I was told I would receive corrected pricing and additional information/photos. After hearing nothing back, I personally followed up by phone and was told Alex would contact me later that same day. Unfortunately, I never received a call or email. At that point, I even reached out directly to Norris, the technician who originally came out to measure my door, because I still had his number from when he called before the appointment. I explained that I was disappointed with the lack of communication, and he responded saying he would have Alex call me. Once again, no one ever followed up. For a project that costs thousands of dollars, communication and follow-through matter. I understand companies get busy, but repeatedly promising callbacks that never happen is frustrating and discouraging as a customer who was ready to move forward. At this point, I'll be taking my business elsewhere.

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!!

With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are.

RESPONSIVENESS - very fast, very responsive, very professional. A tad too frequent, but apparently roof repair is a competitive business. INSPECTION - scheduled and conducted efficiently; exceptionally thorough inspection report (David). COST - in line with all other quotes, which are apparently driven by the insurance estimate. Green Oak differentiation included owner interaction, master roofer certification, 5 star rating, excellent warranty, professional documentation and workflow management. WORK - scheduled efficiently, material arrived on time the day before, crew arrived on time the day of, work was conscientious and completed in 3/4 day (townhome), clean-up (including loose nail hunt) was impressively thorough. AFTER - received certificate of completion in a timely manner, along with photo record of repaired roof. Not being a roofer, it's difficult to assess the integrity of the new roof & shingles, however the end result appears clean and professional. Suspect the new, high-quality roof will increase the townhome value and/or decrease time to sell based on the high-quality products used and overall curb appeal of the work. Overall quite satisfied with Green Oak. Recommend.

Brian H. took me through the process from start to finish, including an insightful explanation of the insurance claim process. The free estimate happened within a few days and ended up being lower than the insurance-assessed quote. He recommended a roof "tune up" as part of the package without pushing or trying to upsell me for more, which i really appreciated. He also accommodated my inquiry of adding on the installation of a bathroom exhaust vent cap, which was missing when we moved in. After being extremely reasonable on pricing and lighting-fast on responses, they scheduled and completed the work the day after signing.
