Our Completed Projects
Doosan Bobcat
Doosan Bobcat in Johnson Creek, Wisconsin. We completed the design and installation of a massive 200,000-square-foot renovation that included 1,800 sprinkler heads. Utilizing our orbital welder, We were able to prefabricate all of the sprinkler piping for this project.
One of the biggest challenges during the installation was completing the work while the plant remained fully operational. Our team worked around and above active machinery throughout the facility, requiring detailed coordination, strict safety measures, and careful scheduling. Through clear communication and proactive planning with plant management, we successfully completed the project safely and on schedule.
Springhill Suites
Springhill Suites in Milwaukee Wisconsin. We completed the fire protection design and installation of a brand new 4 story, 94 unit hotel. We utilized a plastic pipe system for this building.
Mill Creek Academy
We completed the install of HVAC, plumbing and fire protection on this brand new 42,000 square foot school. Our engineering team utilized 3D drawing software to navigate piping and ductwork through the webbing of wood scissor trusses including the dry sprinkler system.

My experience started with a call to Southport for a second look opinion. They were highly recommended. The technician Tyler was able to find and explain the problem/s I was having with my 20 year old furnace and AC unit. He went over my options thoroughly, quickly set up a time for Justin to go over those options with necessary numbers, and the appointment was made for a new furnace and AC. The technicians Max, Diego and Aaron did a fantastic job with removal of my existing system and new installation. They treated me and my home with respect, paying great attention to detail. Max explained the process as they went along, making sure any question I had was answered. Nathan, the sales manager was even kind enough to stop and make sure I was happy with the whole process. The entire staff exceeded my expectations and were so professional, courteous and respectful, which is especially appreciated, as home repairs can be quite stressful. I highly recommend Southport.

Southport responded quickly and effectively in replacing our sump pump on the day of the storm on 4/17/2026 where our lower level of our home flooded. Both Alex and Andy responded. Despite not being on call, Andy responded as a neighbor and ensured that the sump pump got installed himself so that the overflow would stop and damage would be minimized. This included working in the midst of the water at 3am. I suspect the water damage and overall impact would have been exponentially worse if not for Andy’s dedication to solving the problem. I was out of town when this occurred and both my spouse and I are very grateful for Andy and Southport’s prompt emergency response. Approximately a week later we proceeded with installation of a battery backup. Thank you for the service and assistance in mitigating this very stressful and difficult situation.

I saw Southport at a remodeling trade show at Monona Terrace in Madison, and requested an inspection of the heat pump in my 40+ yo condo. The person scheduling the appointment handled a last minute change to the appt professionally and accommodated my request. The technician was also very professional and knew his trade incredibly well. When the inspection unsurprisingly showed the unit needed replacement, I was still provided with repair options, pricing on individual repairs, and payment methods. A definite bonus was the tech was personable and empathetic, going as far as laughing at my dad jokes (they're bad, trust me 🙄). Finally, there was no pressure to pay for additional services, or any hard sales to purchase anything or repair on the spot. Overall a great experience, I will be using Southport going forward.

Last week we had Tornados in our area. While listening to the warnings, the meteorologist mentioned a back up sump pump would be beneficial to have. I scheduled an appointment with Southport home services. Andrew came out and explain how the system works. He then gave me prices.. He was able to install the system the same day. I highly recommend Southport Home Services.

My technicians were quite well informed and highly skilled in replacing all of the plumbing in the basement (hot water heater, sump pump, back up sump pump and battery, ejector pump). Highly recommend this company and the specific technician that performed all the work.

I noticed water on the floor on Friday morning below water heater. Called and service tech came out early afternoon. Problem confirmed and new one installed by late afternoon.

With all the flooding we had I was concerned about how often my sump pump was running and if it was working correctly. Tanner from Southport was here promptly and checked my sump pump over as well as the drainage hose I installed making sure everything was working as expected. He explained what to watch for as well as the services Southport offered. I am grateful for his professionalism as well as Southport's Shield program!

Southport is always great!! I've had them out for a couple of planned items in the past, so when my sump pump died this morning, they were my first and only call. Not only did they give me a 2 hour time frame in the first phone call, but they continued to call me back and update me as the technicians arrival time changed! Justin was the technician dispatched to my house. He was awesome. There's simply no other word for it. He looked at the pump, gave me 3 quotes, let me pick & choose the features & warranty I wanted, then immediately went to work because all the parts were already on his truck. He also gave me the name of a water remediation company they work closely with and coached me on what questions to address with that other service provider!! I will truly never call anyone else again. Southport has earned my business FOR LIFE!
