I am SO happy with the windows at home. We are only renting that house at the moment, and have only been there for 1 year, but I have never seen that glass as clean as it was this morning. It was amazing! I cannot believe how disgusting those tracks were, especially on the sliding door, the door even opens better now!! You both went above and beyond what we expected, and we could not be happier. I am happy to continue raving about the fantastic job, and recommending you.
