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!!

I hired Winfield Builders to replace two old skylights in my Rockville home, and Zach and his team…read morewent above and beyond. My project was complicated because my 1980s drywall shafts were the wrong size for modern solar blinds. Instead of just "making it work" or creating a huge mess with drywall dust, Zach proposed a brilliant custom solution: building a clean birch veneer box with custom trim. It looks stunning and kept my house completely dust-free. What impressed me most was Zach's integrity. During the install, a small piece of my old plastic molding snapped. Instead of ignoring it, Zach took full ownership and replaced the trim on both skylights with upgraded foam-backed wood molding at his own expense to ensure everything was airtight and uniform. It is not a simple fix but an upgrade, for free. See the attached before/after pictures and the broken plastic. Like most customers, I contacted a few contractors before selecting Winfield Builders. Their price is VERY reasonable, and the communication through Yelp was professional and transparent. It is rare to find a contractor who cares this much about the details. If you want a crew that is honest, skilled, and delivers a beautiful finish, call Zach. 1000% recommendation!

Zach made a strong impression from the start--when he came out to inspect my roof and I told him of a problem area, he went up on the roof to look at it! Replacing the roof took only one day, the crew arrived early and worked very hard. I also had the gutters replaced, opting for 6" gutters. The larger size has made a huge difference, as they're less likely to get clogged. My home is in good shape thanks to Winfield Builders!

Apparently they are unfamiliar with the fact that they are on Groupon so I had to call back when someone from the company was in the office to get on the schedule. They had availability for two weeks later. I wasn't in a rush so I don't mind the wait. I wasn't scheduled for the 12-4 time window. On the day of I had a work commitment that came up last minute. They were very accommodating when I called so I was pushed further back on the timeslot till after 3 PM so I could be home for the service. The technician Isaiah arrived and informed me what he was going to do. Afterwards he sent me a detailed report with photographs of my gutter system. Thankfully, everything looked good and I did not require any additional services after the cleaning and tuneup.

I am so happy with my new windows, and especially with my new sliding glass door installed my…read moreAmerican Home Contractors last week. 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.

I had spent months researching how to fix a glass shower door. Other contractors recommended I replace the entire shower door since I couldn't fix it myself. I was prepared to have them say the same thing but they looked at it and said it could be repaired. After a few visits, they completely repaired it. Throughout the process, they were honest about what they could and couldn't do (e.g. they never gave unrealistic timelines) and stuck to what they said. In the end, we have a shower door completely restored and have saved a few thousand dollars. Thanks, guys!

I called and described the frame issue and their support said they had no openings for 2 weeks. I said I would call back. I decided 2 weeks was okay and called them back. The rep said "only glass, no frames, no windows, only glass". I was baffled. I said, are you sure, and she said, "only glass". I hung up I checked the website and saw the contradicting blurb on their site and called her back. She repeated and said, "only glass". I told her that they should fix the website and hung up.

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.

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.

I am so devastated to hear the horror stories from other customers regarding this company. I can…read morehonestly say I didn't have a bad experience. We had an emergency late in the evening where we came home and found out that our kitchen window had been broken. It wasn't something we could wait for until the next day because it was a massive hole in our window. Bugs and little critters from outside could easily make their way in. We called the company a little bit after 7pm and he surprisingly said he could meet us that night to take measurements of the window. He told us up front that if the window was longer than 60 inches, he would not be able to replace it that night. He proceeded to ask us for our home address and to text him photos of the window. I asked him for a rough estimate on how much it would cost to get the windows replaced and he gave us a fair price. We agreed and he told us he would be there in about 1 hour. He arrived about an hour later and began examining the window. He told us that based on the photos we had texted to him, he thought the cost of the windows would be the amount he originally quoted to us, but based on the actual size of the windows after he measured it, the windows would be less money. He cleaned up the glass and carefully removed the windows. He told us he would leave and be back in about an hour from that time and sure enough, he returned with some new windows. He installed them perfectly and we paid him upon completion of the work. He even offered to come back at a later time and conduct a home estimate on how much it would be to have new windows installed. He was very polite and very helpful to us and we were so grateful that he was able to assist us that late in the day.
