"Jim & Rob handled the service. When they realized that they were running late, they called early on to let me know. They were a completely in sink team. They were efficient, knowledgable and extremely courteous. My father had owned his own plumbing company post WWII, and was one of the first licensed plumbers in the state of Illinois; accordingly, I watched & had many plumbing questions regarding the install. Jim & Rob patiently shared their expertice. High recommend. A great experience."
