Spartan Plumbing - Predatory Price Gouging- $900 an hour for labor.

I had a leaky p-trap, spartan came out, suddenly the disposal was punctured. I was quoted, $1081 by spartan to replace the now newly leaky garbage disposal. The part cost $169 at ace hardware and it took me only 20 minutes to replace. They were charging $900 for 20-30minutes of labor. Other plumbers quoted me between $125-250. Spartan refused to provide a break down of cost when asked. Do not use them at all cost.
