"Lou showed up on time for the quote and won us over. We scheduled him to do the actual work and he was not the best at keeping appointments or notifying us if he could not make it. The work finally got done about two weeks after the original appointment. He was scheduled to return for some finishing details and final electrical inspection. Again several reschedules (he had not even been paid yet which really made me wonder. I am sure he was not going to work for free). Had to leave messages that normally went un-returned. He did finally return for the last details but still no final inspection (we did pay him on this visit). Began having an issue with one breaker. Scheduled him to check it. No show. Left messages, no return calls. So here we are a couple months after beginning this project, mostly happy with the work that was done but not happy about scheduling issues, lack of follow up and still no final inspection."
