"They did a good job and the workers were great the only issue i have is they didnt install a water shut off even though i had one in the old system and i wasn’t told the price i was given to do the job didnt include one until the end of the job i would have paid extra for it i had to change a water filter since the job was done and i have to go to the street to turn off the water if i have a busted line in winter and the box is covered in ice and snow how will i get the water off this is my only gripe about the work no full disclosure i was in a rush to get it fixed it was leaking bad they should disclosed that when the estimate was done its made me rethink using them in the future"

"I posted the information on Angi. They contacted me quickly and responded. David arrived early the first time. He answered my questions in detail and analyzed possible scenarios. The estimated cost was reasonable. After I accepted the quote, they quickly scheduled a work appointment. Of course, they arrived early again. I really appreciate punctuality. Mark inspected the site and explained the problems they found. He carefully explained the solutions and answered every question I had. The repair quote was also reasonable. The three of them worked very well together, with clear division of labor. They were meticulous in every step. The final result completely exceeded my expectations. Without a doubt, I will use them again and recommend them to my neighbors. Oh, and Andrew did an excellent job too. Strong muscles, handsome appearance, and hardworking. In short, I highly recommend their team. I believe you won't need to look for any other company after using them."

"Great experience using The Otter Guys! They installed a gas log fireplace and set up for future natural gas appliances. They got us a great quote and the job was done fast and efficiently. They communicated every part of the job to us which was very important to our family. There were no surprises and the job timing and quality went above my expectations. Looking forward to using them again for my future household needs as well as friends and family ."
