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

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.

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.

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!

Custom Concepts Construction (CCC) did two major jobs for us in late 2025, mostly involving…read morereplacing wood with James Hardie fiber-cement materials, other carpentry work, and gutters. We are extremely pleased with their work. We chose CCC for three reasons: 1. They are Elite Preferred James Hardie installers who carefully follow the Hardie standards of installation. 2. The co-owners and lead carpenter are experienced with all aspects of residential carpentry, having built homes and additions in the past. 3. The co-owner in charge of sales, Michael Swank, gave authoritative, unpressured advice and presented a masterfully written, detailed proposal with a detailed description and all charges. The price of their proposal was similar to, or lower than, those we received from other exterior contractors. One of our jobs was to replace all wood siding and trim with Hardie siding, trim, and panels on two three-story towers. I expected some difficulties with scaffolding over a stairwell, but the lead carpenter Kerdy and his assistants did the job masterfully, resulting in carefully executed, beautiful results. The second job was to renovate our 100-year-old garage by not only replacing sheathing, siding, and trim but also installing new interior wood beams (rafter ties and collar ties) and additional studs recommended by an engineer to stabilize the sagging garage framing structure. They skillfully manipulated the framing to straighten out the rear garage wall and front central post, which were bowing outward, as well as to straighten out the sagging ridge. During this process they erected temporary support posts inside the garage. We were glad to have hired a team who knew what they were doing with framing as well as exteriors. They also installed a new Pella window and figured out how to do the problematic moving of our shed next to the garage. Their subcontractor competently replaced all of our gutters and downspouts with larger ones. The project manager Daniel Harper, a co-owner of the company, directed the carpenters, handled the logistics of the job, and ensured the high quality of the finished product. We found CCC to be a well-organized and responsive small firm that is easy to communicate with. It was a particular pleasure to interact with Kerdy, the lead carpenter, who always provided clear and polite explanations. Billing was expertly handled by Katherine, who took our credit card payments without charging a fee. In summary, we highly recommend this company for exterior work!
