To all the companies who depend on Performance Contracting Inc. – Knoxville to do their industrial cleaning, watch out. They will try to overprice. Take your business elsewhere when they do that. PCI’s Operations Manager – Esley Hall and his incompetent protege, Elise Brown are known for ripping companies and their own employees off. Their personal behavior is very immoral, as well. Google their names and read for yourselves. They’re not professionals. Bad for business.
