West Allis, WI · Est. 35+ Years
IGSHPA-certified geothermal installer. Caleffi Solar contractor. One of the few plumbing companies in SE Wisconsin qualified to install geothermal loop systems and solar water heating — alongside complete residential and commercial plumbing.
Repair, remodel, and new construction for residential and commercial properties. Water heater installation and repair, sewer and drain cleaning, water softeners. The full conventional plumbing menu — done right for 35+ years.
Geothermal heating and cooling, solar water heating, hydronic radiant heating. These are the systems most plumbers won't touch. We're IGSHPA-certified for ground-source heat pumps and Caleffi Solar-certified for solar thermal — a short list in SE Wisconsin.
Video camera inspection, hydro-jetting, 24-hour emergency response. When you need to see inside the pipe or clear a line at 2 AM, we have the equipment and the availability. No call centers — you reach our people.
Carl's Plumbing Services Inc has been operating in West Allis and across SE Wisconsin for over 35 years. In that time, we've seen plumbing technology change dramatically — and we've stayed ahead of every shift.
We're one of the few plumbing contractors in the Milwaukee metro area holding both IGSHPA geothermal certification and Caleffi Solar contractor status. That means when a homeowner or commercial developer wants to install a ground-source heat pump or solar water heating system, Carl's is on the very short list of qualified names.
They didn't just fix the problem — they explained the geothermal option clearly, gave us a real quote, and had the certifications to back it up. Hard to find that combination.
