"The fact he came out that day with no appointment and said just let me come out and give you a quote No Charge. This was just before the scheduled installer showed up to charge me $89.00 to give me a quote!!! I had to send them away. I can't afford to pay $89 for a quote for work . Even if it is applied to the service done."

"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."

"Ryan and his coworker were very professional and worked very efficiently. Answered all my questions and even took care of a leaky pipe and hooked up my icemaker on my fridge in addition to installing two new faucets. It only took them an hour. When the time came for me to pay the bill I was very pleasantly surprised. I would hire Collins Sanitary again w/o hesitation and would highly recommend them."
