Windows On Washington, Ltd.

Installer even fixed an issue with another company's install on different door.

Excellent service during entire process! The sales rep and person who took the final measurements were professional and informative. Becky was great with communications and scheduling. She was very understanding and patient about postponing installation since we are high risk. Joon and the installation team were prompt, courteous, meticulous, efficient, and safe. The results were great, the windows look nice and work well. We would not hesitate to use WOW in the future and highly recommend to anyone.

Excellent company and reviews of window product are great. Sales consultant was very knowledgeable . Markets on quality of window not on pricing which sold us.

Nothing to add until project is completed

Very very impressed. For anyone that wants a window company that does a top notch job, sells an excellent product, and doesn't want to ever worry about any part of their window installation, this is the company to use in the DC area. For many of you, you probably started out like I did, looking for the best value, generally optimizing for price. The more and more I dug into Wow, the more I realized how horribly wrong things can go with getting the wrong type of window, choosing a mediocre manufacturer, and ending up with a subpar installation. My experience with Wow was none of these things. They sell a very high quality product, the OKNA 700s, gave me a lot of confidence they would fix any issues that arrive.for the next 20 years or more and did a picture perfect installation. From the detail on the caulking and insulation to making sure none of my drywall was damaged, I was incredibly impressed. Are they the cheapest in town? No. But they are the best. If you want to buy windows and not have to worry about the installation, quality of the windows or lifetime issues around the windows... use these guys. Hands down.

I had four sliding glass doors replaced. Most companies were pre-set on the one or two options they would sell me. Windows on Washington (Zach) took the time to measure and discovered all of my doors were a non-standard size by 4" each, which I independently verified (star 1 for WoW). Then they offered several options, to include competitive pricing on a competing bid (star 2 for WoW). Ultimately we "settled" on low maintenance 5-point locking doors with exterior keyed locks, which only WoW offered as an option (star 3 for WoW). For the installation they worked around the unusually rainy season and our schedule to get them installed. We knew we had wood rot in the old door frame, but they (Young Kim and crew) also repaired part of the housing structure at no additional cost (star 4 for WoW). Finally, they offered us 12-months with Zero percent financing (star 5 for WoW). We did have a few issues along the way, but once I communicated with WoW they (Cathy Mejia) were incredibly helpful and worked to make things right... what more could anyone ask for? I WILL BE using them again to replace the front door and a few other items on my fixer upper. I HIGHLY recommended this team!

I got 5 windows installed on the front of my townhouse. Windows on Washington were professional from the start. Greg did a great job showing me their window options and they do use excellent quality windows (I reviewed the windows online myself). The installation went very smoothly, except one of the windows came with the 8x8 grid pattern instead of 6x6; once I noticed the mistake and told the installer, he called the office right away and they ordered the correct one to have it replaced within a few minutes. One thing to note is that the whole process takes a while, since they are custom windows that have to be ordered and made. For me, it took about 2 months total from the consultation through the installation (early July to early September). Perhaps if you order in the winter, the manufacturer would be able to make the windows quicker.

Jose was very professional and did a great job.
