"We had them clean the inside/outside/screens and sills, it was night and day how much better we could see afterwards. I didn't realize how dirty all of our windows were. The used just water on the windows too, I was shocked that no streaks were present afterwards. I will be looking to do this more often in the future and would not hesitate to use Virginia Window Cleaners again."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."
