Thanks, Josh! I thought I was going blind, but it was just our dirty windows! I can see clearly now! Thanks for a fantastic job on all of our windows -- the colors of Spring in Tahoe are even more vibrant! You did a fantastic job; I can't recommend you enough! Fast, efficient and courteous.

My job was really small. It involved an exterior glass panel of a sliding door unit. Josh said it was small but advised me how to handle it. His advice was perfect and the problem was solved with his product recommendations and my scrubbing.
