I needed new windows and new sliding glass doors. The previous owners of our appartment had put in…read morethe cheapest possible units with the cheapest possible labor. With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are. We are very happy with our windows. Almost as happy as we are with the people who got them into our home.

The materials are of top quality and the workmanship is good overall. What I have found, like many others, is that when you ask for a quote, they're all over you like flies, but AFTER the job is done, you're met by silence. We had two issues - some bulging siding and a torn window screen. No matter what number we call, we get routed to an answering machine. Does it even record? Who knows? At any rate, no one ever calls back or stops by. We'll probably, also like others, end up having to take care of it ourselves.
