Eric knows windows! He is THE expert, and I trust him to have all the answers. I have complete confidence in this company to do a perfect job every time.

Amazing all throughout the whole process, sales person was knowledgeable and nice. Had a small issue which was resolved quickly and communicating was always easy to do. Every single person responded to emails which was refreshing too. Windows are great and the install went smooth as well-actually ahead of schedule since it only took about 5-6 hours.

This is a company that stand behind their products and installation. We have them installed our windows about 10 years ago. Last week, my wife tilted the window for a cleaning and could not close. She asked me to check without telling me what she has done. Naturally, I tilted the window one more time. Then I heard a cable snapped. After watching youtube video, I realized that both tension cords have snapped. The window was inoperable and we can't tilt it anymore. I gave them a call and they setup appointment immediately. A window tech came and fixed it in less than half hour. We have been very happy with the windows and this last experience made it even better. We'll definitely call them if we ever need windows replacement again. Thanks WoW !!

We have used Windows on Washington for replacement windows, doors and siding repair. They are outstanding! The quality of their work and customer service is second to none. I referred them to my friend for window replacement and after many estimates, she also went with them. They do not do the hard close, which I appreciate.

We had the windows on the front of our townhouse replaced. Zach was good to work with, and we're really enjoying our new windows!
