"Evan and his team did an incredible job fixing a water issue we had for nearly 10 years in our Alexandria Verizon Retail location. They could not have been more professional and efficient. We will continue to use them in our stores across VA. Their ability to take care of a large commercial job at a fair price makes them out go to drainage and water guys."

"Great job. It took a while for permits to come from the county, but once they did, these guys got the job scheduled and done quickly and with great workmanship."

"They were great."

"We were very pleased with the work done by Windows On Washington for our insulation project. They were very friendly and did a great job of communicating with us throughout the project. The estimator Shayne was very helpful in providing us and explaining several options for our insulation needs. And the installation team did quality work with attention to detail. Brian, Anthony and Rubin were very willing to explain any details to us as they performed the work and went the extra mile to ensure we were happy with the end result. We recommend them highly"

"Bottom Line: This is the first time we have used this company, and they did excellent work for a reasonable price, and more importantly, built a huge amount of trust with the customer. Communication: Scheduling the initial estimate was easy, but the back-and-forth communication required to finalize the many detailed options was a bit slow; however, the owner Scott Halle interceded and timely communication continued throughout the rest of the process. Scoping Work: This is where Zen Windows really excels, primarily because of the vast knowledge of James Bond. We wanted to replace the single door with side transoms with something that would maximize the opening space. James expertly walked us through the options with cost and wall modification comparisons. In addition, the header above the current door was swelling and pinning the door, and James evaluated the issue, likely water seeping down from an unflashed deck, and provided peace of mind his guys could fix it on site during installation. Quality of Work: Frankly, 75-80% of contractors fail here for three primary reasons: a horrible handoff from the product specialist to the onsite project foreman, project foreman and workers making assumptions about details vice asking the customer, and lack of quality detailed work. The foreman excelled in these areas ensuring we were on the same page for various details such as casing, caulking, and external trim. In addition, he completely replaced the rotted wood structure above and along the sides of the door and added customer-provided insulation where there were gaps. To keep the project on track, they brought in another expert worker and management arrived to ensure the quality of work was high. The end product was beautiful. Pricing: Price was the best of three highly ranked Angie’s List companies. Zen Windows’ expertise, willingness to explain the details of the project, timely communication, and excellent work took the hassle out of this project."

"Great service, they are experts in sidings. They explained the material, cost, etc. Flexible in starting date and payment plans. Strongly recommend them"

"It was amazing. Before the work, it was amazing how little rain it would take to cause standing water in the yard. After they completed, we got 2" of rain in one day and had no standing water anywhere in the area they worked."

"Love our new Grand View Windows from Window Nation 17 Windows and 1 Sliding Glass Door We did quite a bit of research, explored a lot of companies and choose Window Nation for our project. And we are happy we did. The whole process from presentation to installation was easy and efficient. Reza arrived at our house on time for the presentation. He inspected and measured our windows and then launched into the presentation. Reza is knowledgeable about the Window Nation offering as well as the products offered by his competitors. As mentioned, I did some research and had an idea of the features that we wanted and what we should pay. Reza presented the Window Nation Grand View line, which meets our feature requirements, and after a bit of back-and-forth negotiation we settled on a price that was within our range and fair to us both. After signing, Reza described the next steps and set expectations. Overall, the presentation took only about an hour and was relatively painless, with no high-pressure tactics. Several days later, Mike came by to inspect our windows and confirm measurements for the build specifications. This took only about a half-hour. Mike answered some questions about the installation process and said that the windows and door could take up to 6 weeks to build. Imagine our surprise when we received a call a week later to schedule our installation. On installation day, the three-man team arrived on time. They introduced themselves and the team lead, Ted, described the process and then they got right to work. They tarped the paths to all the windows to protect the floors. They were very careful and respectful of our house. The entire team was friendly and polite and experienced and highly skilled. You could tell that they’d done this a time or two. The outside trim work is fantastic and the inside finish work is great. All 17 windows and the sliding door were installed in a single day. Ted went over the operation of the windows and door. The windows and door look and function great. We couldn’t be happier. If you are considering a window or door replacement project, we strongly recommend that you engage Window Nation. They will treat you right."
