Max Schoenwalder Sr. established Max Sr. & Paul Schoenwalder in Newark in 1912. Max moved the family and business to Union, NJ, in 1919. At that time, Union had dirt roads, no running water, and no streetlights. He became a well-known community leader in Union. He served on the township committee for nine years and was mayor from 1932 to 1933. After his passing in 1968, his son Paul Schoenwalder Sr. took over the company. Having served in WWII, Paul Sr. led the business until 1982. Paul Schoenwalder Jr. inherited the company next. He participated in the Union Rotary Club, local Chamber of Commerce, and various community organizations. In 2007, Gayle and Karl, family members, continued the company’s legacy. Gayle and Karl uphold the same family principles Max Sr. established over a century ago.

Gayle joined the company in 1982 and currently serves as Treasurer. Karl became part of the company in 1994 and serves as President. Gayle and Karl are licensed Master Plumbers and HVACR technicians in New Jersey.

Another great service call - this time replacing three (3) steam radiator valves that hadn't been worked on in over 40 years. Lou did a fantastic job working through a very challenging repair.

A very nice technician came to our house to fix a broken hose faucet, but left a rather unsightly burn on our siding and melted metal dripping down the siding as well from where the faucet was soldered on (I assume.) My husband forgot to mention we needed the electrical outlet checked that was directly next the faucet on the outside of the house. The tech didn't even attempt to help us with it, even check it with a voltage meter, because it was not on the original job order. This is understandable since he has other jobs to get to, but frustrating after seeing the damage.

He was very friendly and quick, which was appreciated, but for over $200, I would have liked him to not leave it looking worse than it did before. We have had really good experiences with them in the past, but this job wasn't their best

The receptionist, who claimed to be an owner, was extremely rude for no reason at all. Do businesses not realize they have everything to lose by being nasty to the public when they call? I feel bad for people like this, being this age and not knowing or caring about manners. This is exactly why you lost the opportunity to work for us.

Disgraceful service. Called plumber to fix job which was attempted but unfortunately not withstanding. Paid hefty fee for this. Next he came again and left with issue still unresolved. We paid again (now twice for same job) and very next day base board started leaking. I speak to 'manager Karl' and explain resentment at paying a 2nd time with issue still unresolved. Karl not accommodating and tells me ""I have to pay my guy"". He agreed to provide me with a credit when plumber returns to fix. So 3rd time lucky and now I need issue fixed ASAP as winter storms coming. Office tells me engineer has job first thing but would be with me around midday. I wait around all day and at 5pm he still hasn't showed. I call office and Karl isn't around (funny that) as i want to share my frustration with him once again. I'm offered no assurances that the plumber can come tomorrow at a nominated time, even after i explain I'd needed to use a vacation day today and was disgruntled following previous back and forth. What a terrible way to treat a valued customer. I strongly suggest looking elsewhere for plumbing and heating needs as this company doesn't deserve your money. By the way Stan (our regular plumber at M&P) is great, just a shame those around him aren't. 1 less customer.

From start to finish, I had a really great experience with M&P. I prefer to use a local company, these guys are a mom and pop operation with a good crew. The prices were reasonable, the work is quality. My tech had a pretty good season of humor too, always nice to feel comfortable with someone working in your house. I will definitely use them again. Thanks for coming out today!
