Alta just finished cleaning the windows of my standard, 2-story house and they are sparkly! Genaro is a super nice guy and does all the work himself. He returned my call immediately when I first reached out. Came by the next day to scope out the job and provide an estimate. Then after I scheduled the work for a week later, he sent me a reminder email the day before. Actual cost was exactly the same as the estimate. I'm totally happy with the entire engagement.
