We purchased our dishwasher from a big box store. Upon the start of installation they stated that we needed a shut-off valve & could not do it. So they left the dishwasher in our family room & left. We contacted Hartwig Mechanical. They arrived within 2 hrs of our call and replaced the valve & installed our new dishwasher. We are VERY happy with their fast service & the personable great plumber. Highly recommend!!!

I was very happy with the job that Hartwig Plumbing & Heating did for us right before Labor Day weekend. Casey, one of their plumbers, was at our house within 90 minutes of my call. He quickly identified the problem with our hot water heater and resolved the issue to our complete satisfaction.

You can NOT get any better than Hartwig Plumbing. They were referred to me after a fire at my house caused by another plumbers error. From the 1st phone call to Hartwig, Jen was above & beyond helpful, kind, quick, honest & knowledgeable. I felt like I was talking to a friend. She had me set up to have a new water heater installed quickly since I had been without hot water for 2 weeks. Mike, the installer was patient, knowledgeable, honest, nice, hardworking & extremely thorough. I was nervous after the fire & Hartwig made sure I was informed as well as completely confident in the installation. Due to EPA changes, the new water heater turned out to be larger than the one I had. Mike, the owner of Hartwig, came to my house to help me find a solution to the new hot water heater size not fitting correctly in the cabinet. He was honest & so helpful. This was not Hartwig Plumbing responsibility to find a solution because I was the one that said to get that water heater. It just shows what outstanding service Hartwig Plumbing provides. I am grateful that they were referred to me. I will always use Hartwig in the future as well give them the highest recommendation.
