Don't waste your time, he won't waste his...
You call, leave a voicemail, he won't call back. This guy was contracted by my home builder to do the plumbing in our new home, and we've had three issues in the 2.5 years we've lived here. Of the three times, he called us back ONCE to tell us he couldn't do anything. The other two times, he didn't bother to call back at all.
Awesome work ethic, dude.
