Windows on Washington provided the best value among competitors with a top quality sliding glass door at a very good price. The expert installation team, led by Joon, removed the existing door and installed the new door in just three hours, working like a well-oiled machine. We love the final product!

At all stages, the team arrived timely. The team meticulously removed old windows and installed new ones. They ensured the windows were clean and properly worked. The team tidied up. Joon showed me all the features of the windows and screens. I will definitely be using Windows On Washington for door replacement in the future.

All our our projects have been completed, and we couldn’t be happier with the results. Our house looks fantastic, and WoW did an excellent job. Both crews arrived on the date and time they were scheduled to work, and we didn’t have any issues at all. The work was first rate, and they also do a great job of cleaning up after the work has been completed.

We just had our four sliding glass doors replaced by Windows on Washington and are very pleased with the results. They provided great customer service and kept us fully informed throughout of the status of our order. The installation itself was very smooth and highly professional — superb attention to detail by the crew chief. Highly recommend them!
