Not good. Hired them to install a new garbage disposal & redo the plumping under the kitchen sink. They did not sell one we wanted & they were way overpriced so we bought one elsewhere. They put it in & did not install the new sink flange that came with the unit we purchased & instead left the old corroded one in place. Then they had the audacity to take the new one with them.

Then when questioned about it they lied & said the new unit didnt have one. Problem is we had looked at it before they came. It was attached to it & they actually had to take it apart before they installed the disposal. This actually happened a few years ago but I get just as upset every time I look at the old corroded one. Had they at least left it, we would have hired a reputable company to redo it. On top of all of this they charged a ridiculous amount on the bill. Stay away & find anyone else.
