We were very pleased from beginning to end. The sales person that came out for the estimate to the follow up estimates to the actual installation itself. We were pleased with every aspect of it. I was most satisfied with the speed. They accomplished 27 windows in two days. It wasn't just how quickly they did it. They really have their act together. They're very efficient. I really like that they cleaned up after themselves everyday. They left the house as they found it. We did get three separate estimates. Windows on Washington was one of the three companies that we had come out and give us an estimate. All three of them had a different product. We were most impressed with Windows on Washington, their product, the salesman, the technical expertise, the complete package, is what sold us on Windows on Washington. We were most impressed with Windows on Washington and their price was comparable.
