This is the second time we used Windows on Washington to replace windows in our house. As with the first time, Greg Schwartz was outstanding to work with in placing the order. Greg is extremely knowledgeable of the Okna windows we had installed and he made the order process extremely easy. Jose and Tomas, the installers, were also outstanding! Jose installed our first set of windows and did an outstanding job with them, so, we were very pleased to see Jose return for the new installation job! Jose and Tomas left our house (inside and outside) spotless - other than the new windows, you would never know they had been here! Julia, in the office, also was very helpful in scheduling the installation date and making sure we knew what we had to do to ensure a smooth installation. Finally, we love the Okna windows we had installed the first time - they made a big difference on keeping the heat out in the summer and the cold out in the winter - this is the reason we ordered the same windows for the new project.
