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 !

I highly recommend them.

However, I didn't use that company because they wanted a lot of money to redo windows and doors. Some time later I remembered Zen windows and reached out to them for a quote. It was the best decision we have ever made. I cannot recommend the Zen Windows team highly enough for their outstanding work in replacing the windows and doors in our townhome. From start to finish, their professionalism, attention to detail, and craftsmanship were truly exemplary. Every step of the process was handled with precision and care--no detail was overlooked. The team took the time to ensure that every window and door fit perfectly, operated flawlessly, and met our expectations. Their expertise was evident in their meticulous installation and their ability to troubleshoot any challenges that arose. Not only were they efficient and on time, but they left our home clean and tidy at the end of each day. It's rare to find a team that combines skill, professionalism, and a commitment to customer satisfaction, but Zen Windows delivered on all fronts. If you're considering window or door replacement, trust Zen Windows--you'll be thrilled with their results. They've completely transformed our home, and we couldn't be happier with their work.

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.

I reached out to Green Oak after searching on Yelp (s/o), and was extremely glad I did. 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. The team was efficient and respectful, with a huge attention to detail. TL;DR - Highly recommend giving Brian and Green Oak Exteriors a shot to help fix your home exterior issues, especially when you are in a bind with your insurance company!

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.

We'd had trouble getting a contractor for such a small job before, so I appreciated that. They were able to come for an estimate the day after I called, and scheduled installation very quickly after the glass arrived less than a week later. The work was done in under a half hour, looks great, and they left no mess or trace at all. The total cost was $295, which felt reasonable to me. I'd happily hire them for similar work in the future!

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!
