I had a phenomenal experience with Windows on Washington. I had an old wood french door that desperately needed replacement. Joon and his team did excellent work installing, making sure to explain all the details so that I was fully informed, and going to extra lengths to make sure the door fit absolutely perfect. I am very satisfied with this team.

We recently had two large sliding doors replaced by Windows on Washington, and the entire experience was excellent. The team, led by Joon, arrived on time, worked efficiently, and left the space spotless. They were knowledgeable, answered all of our questions, and took the time to walk us through how to use the new doors. The whole process was smooth from start to finish, and we couldnt be happier with the results. Highly recommend!

WoW was absolutely amazing installing 23 OKNA DH windows. They are beautiful and feel so well made. Lowest air infiltration on the market. Competitive pricing. Joon and his team were also incredible before and during the install. Impeccable work. Excellent clean up. Will never use anyone else for a window or doorinstall. Considering siding with them as well as they are very conscious of using the opportunity to close gaps and create a tighter seal of the house. Very important to us as family member has asthma. Thank you!

Thank you for this fantastic review! We’re thrilled you’re loving your new OKNA windows and that Joon’s team delivered the craftsmanship, care, and clean-up that we’re well known for. It means a lot that you’d trust us again for future projects, and we’d be honored to help with siding when the time comes!

From start to finish everyone and everything has been fantastic. I could not ask for a better group of contractors. The window color was almost a perfect match to our 8 year old outdoor trim paint color.
Windows On Washington, Ltd.'s reply
Thanks so much for this great review! We’re so glad your experience was fantastic from start to finish, and that the new window color blended so seamlessly with your existing trim. We truly appreciate your trust in our team!
