He spent 2 days "fixing" our sprinklers where we have brown spots. He never gave us an estimate( our big mistake) on what he was going to do & then gave us a $900 bill after the 2 days of work. 1 month later, our lawn looks worse than before. We called him about it & he looked at it but didn't do anything or tell us what was wrong or what he was going to do to fix things. Last time he was here was 2 weeks ago & never heard back from him again.
