I hired Mark to fix a heating problem. I asked him if it was his type of work and he didn't decline. He'd never seen the system before and had to take pictures to send to a reference. he figured out what part was wrong, got a replacement, made the repair and left. That night I figured out that he had not fixed the issue. I called him several times over the next few days with no return phone call. I called in a new plumber to look at the problem and within 5 minutes he saw that not only did Mark not fix the issue, but the part he ordered was wrong and did not fit properly, therefore not making the required solution to get my heat regulated. I'm out $300 for Mark's visit. I tried to call Mark to fix the situation, but I can't get him to call back. I could never recommend Mark to another homeowner.
