He did a big job for us after quoting a VERY reasonable price. Overcharged for his accompanying workers (same as himself, but with 1/4 the skill), then after job was complete and issues with his work came up, he never called me back after 9 attempts. This was 2 1/2 years ago and still nothing. His work ended up costing us as much as the most expensive bid we originally got.
Not a bad guy, but make sure you have EVERYTHING in writing, including a warranty for his work.
Pros: knows plumbing
Cons: Bit of a scammer, overcharges, 9 calls with no call back.
