CRC Plumbing at 2865 Canna Street, Thousand Oaks, California.

I do not recommend Charles. I asked him about a simple repair to an outdoor faucet, and as I work all week, I asked if he could come on a Saturday. He gave me a window of 8-12, and unfortunately, I was away from home earlier that morning. So I made sure to call him ahead of time (around 7:30) to arrange for a later time, or to simply call me when he was enroute so I could run over there (I was ~15 minutes drive away), but before I even finished laying out a few options, he got very upset. So upset that I never even got another word in. I called back that Monday to try again, and all he did was a repeat of our last call and said he'd call back which he never did.
I'm sure he's probably a good plumber, but know that he's very inflexible and a bit rude. I have taken my business elsewhere.
