Diamond Window Cleaning did a great job on cleaning my windows and gutters. They were prompt in arriving, they worked quietly without disturbing me or my family, and they did an excellent job! I've noticed many more birds crashing into my windows lately :). Another thing I really liked about these guys were that they were friendly. My previous window cleaning service had a very grumpy staff that were incredibly rude, but these guys were very polite to me. I was very satisfied with the results that I got. I will definitely be hiring them next year. I'd recommend them to anyone that wants a great window cleaning service for not a lot of money!
