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. We are very happy with our windows. Almost as happy as we are with the people who got them into our home.

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 putting it off because I was tired of companies calling and emailing non stop after giving a quote. Zen Windows called me once, they gave me an estimate, and then we decided to book with them. They didn't call nonstop until we decided - they gave us time to think. The process was so easy and they did an awesome job installing. The sound has been lowered SIGNIFICANTLY. Would recommend to anyone!!

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!

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.

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 !

I've had issues with my patio door for years - it was difficult to slide open/shut. It's a HUGE and heavy door that can not be easily uninstalled/repaired. I took a chance on Premier Windows & Glass and they arrived right at 0900 as promised, uninstalled the door, diagnosed the issue, obtained & installed the part; all within 2 hours. The contractors (Oleg & Maks) were very respectful of my home and I was super impressed by how quickly & efficiently they were able to make such a difficult repair. I paid around $300 which was substantially lower than other quotes I had from contractors claiming it would be $800+!!!! I hired them again a couple weeks latter because after replacing the netting on my window screens I wasn't able to reinstall the frame back in the window. This time Dennis came (punctual, just like the first time) and installed it within minutes, but also went above and beyond to repair some of the damage I did in my first attempt to reinstall. He didn't even charge me. The quality of their character quickly shows through the actions and demeanor. I'll continue contracting and recommending their services! Thank you very much Maks, Oleg, and Dennis!

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.

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.
