Arif was very honest with his assessment, made sure that I had exhausted all necessary resources before spending anything out of my pocket. His patience and professionalism was at the forefront of his dealings with me as a customer. Needless to say, his team were very knowledgeable and exceptionally helpful. I was so impressed with the company that they are on my list for another project and I'm definitely recommending them to anyone that is in need of their plethora of services. The value they've brought to my family is incredible. Now my family doesn't have to worry about our child getting sick because of the mold. Thank you

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.

They cleaned throughout the entire process, installed all products that fit perfectly with expert skills. They did a thorough job at insulation replacement windows and the finish caulk job was immaculate. The look from the curb is stunning and I can notice how well the windows are performing as it seems the air is running less in just the week we had them.

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!!

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!

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!

To begin, this company provides a very good window. They represent themselves as providing…read more Superior Selection, Expert Installation, No-Hassle Warranty. Safety and Accessibility, Beautiful By Design, One Day Installation, Easy Maintenance. and Long-Last Materials. Having just had 13 windows installed, I have no reason to refute any of these claims. From my experience their primary focus is on making the sale and not ensuring a high quality customer experience. Pricing transparency? Clear as mud. They gladly apply discounts to reduce the "actual cost" that are pulled out of an I pad. Smoke and mirrors. Even greater savings are available if you "just sign today --- but no pressure". Expect to learn everything about the construction of the window and their "design, build, install" model. Do NOT expect them to share any details about the installation process or provide firm timeframes. How so? We ordered custom windows, and they explained those take longer. Makes sense. The we received an installation date longer than we were told to expect. OK. Friday morning before the installation the following Monday we received a text message confirming our installation would be the following Tuesday, as we had been told weeks earlier. It asked us to confirm, which we did. At 4:58 pm that same Friday I receive a voice mail message : "Because your windows are painted I have been advised by our factory there will be a delay. I am tentatively scheduling a new date of ....17 days later." The windows were always to be painted, and the installation date was already moved back 2 weeks as a result. After our order we learned we'd also need to remove all the blinds beforehand. Makes sense - and we were glad we asked. "But there is no need to remove the brackets to the blinds" was the guidance provided. Whew. On the day of installation, the installers removed all the brackets. Because they had to. Installation day: we did not think to ask how much interior access to our home would be needed. All windows needed to be brought through our house (installers asked for access through the longest route possible, oddly), all old windows removed using that same route. Shabby cloth runners were placed on our floors, which at least somewhat reduced the grime from work boots traveling across our floors all day. Alas, at the end of the day after the drop cloths were removed, an installer had to go back through our home with no floor coverings left to retrieve tools and a drop cloth that were left behind upstairs. Enter new grime in places that had dodged that day's grime. Additionally, about a quarter of our window sills were full of grime left over from the installation. Brackets could not be reinstalled (by us) for 24 hours so the caulk could dry. While none of these many annoyances represent deal breakers, Thompson Creek's "expert technicians" who meet with you to pitch their products make an effort to help prospective customers understand "what to expect". Finally --- after providing a check for my deposit there was likely something in the sales agreement indicating the balance would be electronically swept from that same bank account upon completion. What makes me think that? Because upon completion I asked the installer if I could provide him my credit card information to pay the balance owed. "No the office will be in contact with you." Expecting a call, I instead received an alert from my bank app within the hour that the balance owed was being taken from my checking account --- the same one I paid the deposit from. A nice last surprise from this company. This company provides a good product. Their competitors are few, which they well know. That may explain why their "after the sale" process consistently demonstrated they prioritize making the sale over the total experience of their customers.

Disappointing experience -- especially when factoring in the $60K price tag -- I know, ridiculous.

The waiting time can be long-it was at times during and right after the pandemic, due to material shortage, but that was the same everywhere else. The wait was always worth it. Customer service is excellent, as is the communication. Quotes are thorough and easy to understand: please note that you need to provide the rough opening size, and they will make sure to select the correct window size. Pick-up is simple and everyone is helpful and giving a hand to get you loaded. I do need to mention that the contractor I work with does the installation.
