This guy gets 1 star because I can't give 0.
I hired HIM to install a hot water heater and do a rough in for a bathroom in my basement I was finishing. Two issues:
1 - He failed to reconnect the drain from my stationary tub/washing machine. I can only chalk this up to incompetence because he had to cut this pipe to begin with. It just came to an end under the floor! Of course I didn't find this out until after water overflowed the stationary tub and the floor was dug up to find the issue. After paying another company (I no longer trusted this guy) to fix it, Casson refused to pay the cost for the fix - he only referred me to his insurance company who only offered to cover about 25% of the cost. (In addition to this, the 2nd company I hired identified 2 other shortcuts this guy took which could have caused me problems down the line.)
2 - Came home one day not long after the hot water heater was installed and smelled gas. Fire department and Duke identified it as the water heater and shut it off. Another house call later from another plumber to get that fixed. Lucky my house didn't blow up!
