My project was taking out a sink/faucet/disposer set and reinstalling the disposer and new sink and faucet set. The thing that some of the contractors said was that one couldn't install around granite, so I was a bit prepared for damage to my countertop, which was not at all desired. Not a scratch. A few unexpected challenges in that my existing disposer was too big for the piping and the piping required an adjustment, but he had some fittings in truck, so no delay. One of the parts I ordered did not arrive on time so he is coming back to hook that flange up.
1. He was precisely on time and emailed to say how far away he was.
2. Arrived neat and professional with his shoe coverings already on before entering my home
3. knew what he was talking about
4. adapted to surprises
5. most important, got along well with my dog, who supervised the entire project and approved.
