"Jensen Plumbing is professional, friendly, knowledgeable, and truly cares about their customers! As a new homeowner, I have had plenty of questions, and their entire team has been patient, responsive, and happy to explain things. They even took the time to show me how my new drain tile works and explain how they help prevent water from leaking into my basement. When I had a gas leak, they responded quickly and helped me get a gas shut-off valve installed that my home didn't originally have. They are currently helping me with a leaky shower and guiding me on options that will work with my existing plumbing. Their pricing is reasonable, and they make you feel like family. No question is too silly, and the staff are like talking to family friends. I highly recommend Jensen Plumbing for their expertise, outstanding customer service, and genuine care for their customers!"

"I admit I hated having to wait a couple of weeks for the appointment. Smelly hot water is not fun to live with, but they did say they would come out sooner if someone cancelled, but.. no one did. They came out at the scheduled evening, and fixed it! I did speak to the plumber that installed the water heater, and he quoted me $200 for the project, which, according to YouTube, would take less than 10 minutes, and only needed a 1 1/16 heavy duty socket and a bucket.. and some strength. After the discount from the coupon from Angie's list, and the fact that we bought the new Anode Rod already.. we still had to pay $110 out of pocket.. guess it's better than $200 total. Norman's also mentioned the 'usual fee' of $200."

"It went very, very well. I called Windy City Rooter at 8am and before 11am they were fixing the water heater. I thought a new one was needed but that was not the case. The temperature & pressure valve caused the leakage. it was replaced immediately. James and Justin were very friendly, courteous and professional. Both provided excellent service."
