For more than 100 years, Neumann Plumbing & Heating has been serving residents of the greater Sheboygan County area with all of their plumbing, heating, air conditioning and water conditioning needs. Over the years, we have earned the respect and admiration of our customers through the use of quality products and materials installed by trained technicians.

However, it is our employees that truly separate us from our competition. Whether it's new construction, remodeling projects or routine maintenance, we always deliver superior service.
Services
A family owned and operated business since its beginning, Neumann Plumbing & Heating's roots go back to 1912 in the village of Millersville, now known as Howards Grove. Originally a sheet metal work shop, it was started by Arno Usadel across the street from the present location on Millersville Avenue.
There's a long list of things that can go wrong in any home - malfunctioning toilets, faulty water heaters, pipe blockage issues and low water pressure, to name a few. We've seen just about everything. Experience and ongoing training keep our techs at the very top of their profession, and we use the best techniques and products available to give you the best in service and value.
We understand that no other system in your home plays a larger role in your comfort or utility bills than your air comfort system. That's why we specialize in cost-effective heating solutions, including furnaces, boilers and hybrid heat. We provide a one-year warranty on everything we sell and install, and our service department will assist you for a lifetime.
In general, faucet dimensions and sink openings are standard throughout the plumbing industry, so the answer is usually yes. There are a few exceptions, so check the size of the sink opening and give us a call. Noises can be fairly common in plumbing supply lines. If a washer in a faucet or valve is loose, you'll hear it rattling or knocking.

I had a great guy come here today named Oscar. He had a smile in his face the whole time. He had his work cut out for him. I have used other plumbers before to clean out my drains but this guy went above and beyond. He is the only one that ever actually went all the way to the street with his machine. He literally got roots out that looked like the size of a bird nests.

Not just one but 4 big clumps of them. He did it multiple times to make sure it would drain properly. I am a home owner that likes to see the work being done and asks questions. I also try to assist if they need me. Oscar answered all my questions, didn't mind that I was around and was great at communicating what would help if he needed it. I will be using this company from this day forward and recommending them to everyone I know. I truly am grateful for Oscar and the Neumann staff.

Do not use Neumann Plumbing. Do not recommend at all. We use them to install a dishwasher. Installation took about two hours. Poor job was done. Leaking started under the cabinet while using the dishwasher. Plumber came back and fixed the problem the same day. We got charged an extra hour of labor for getting fixed the poor job was done in the first place. Who does that? This is unacceptable. Try GEN3 for pumbling jobs instead. They are honest when it comes to charge for their services. We learned this the hard way.

Called for an emergency water leak of unknown origin and they sent someone out immediately. He found the mystery leak and fixed the problem. Excellent response, excellent service and quality workmanship.

Everyone I dealt with from the estimator installers to the office were first class. I had my own electrical business before retiring, worked with all the trades. Pleased!

They happened to answer their phones before hours and responded to a bad situation at my home quickly. I almost hate to leave a positive review as people will start booking them up tight in case I need them again! : Don't hesitate to call them. Super good people. The service is even better.

Thank you SO MUCH to TJ and everyone from Neumann Plumbing & Heating! My furnace started making unusually loud and concerning noises, then just stopped working. After a phone call, TJ was quickly able to determine that a part needed replacing and was able to get my heating system up and running in no time. Quick and friendly service! I highly recommend this company to anyone in a heartbeat! Thanks again :

After service was completed on the furnace we purchased from Neumann, due to defective parts, I received a very aggressive and accusatory phone call from "Greg" at Neumann Heating. After asking him to explain a very large bill for labor he was very unprofessional and rude. He spoke to me as if I was expected to understood the entire billing structure of his company in a very insulting manner.

The next day I sent a check to pay the bill in full, which will be the last check he will will receive from us. We will be replacing our furnace in the next year or two, just not from Neumann.

We had Newman plumbing for our home build. Our sinks and our tubes in our in-floor heat in the basement have leaked since the house was built. They had to come out to fix a recall on the furnace. Our house was over a year old and I asked him to take a look at the sinks and the in-floor heat connections that were leaking. It was clear that these have been leaking since the beginning of the house build. They charged us a trip charge and for their time. We still have issues with them leaking. I guess I need to move on to a new plumber. Very frustrating

Neumann Plumbing and Heating is our go to for both. We had a sink issue, they came and took care of it, great customer service; we had an uncommon furnace event, the tech who serviced our furnace consulted with another tech so the furnace was fixed and hasn't had the issue since. The office staff is helpful, pleasant and knowledgeable. My kind of business.
