In 1981, we incorporated and became Johnson Plumbing, Inc. We primarily worked in new construction until 2000, when we transitioned to a service-oriented company; we are licensed and bonded for all gas, water, and drain services.

Greetings, I’m Greg Johnson, the owner of Johnson Plumbing, Inc. Since I was five, I’ve been learning the trade by shadowing my dad. I naturally gravitated towards it, loving to hold the flashlight and hand him tools and fittings. In fact, my first-grade show-and-tell was about a thermocouple used in a water heater! I started from the ground up as soon as I was old enough; that’s what you call a ditch digger, LOL. We didn’t have a backhoe back then; I was the backhoe! I didn’t even know trenchers existed until my dad hired one; I wondered why I was hand digging! I like to think he was shaping my character. My dad was known for his fairness and honesty; I like to think we still operate that way. He was the most dedicated worker you could meet, and I’m proud to call him my dad. After high school, I joined the business full-time, married a fantastic woman named Sharon Fauver, and we have two sons, each with four children. We adore them all. Reach out to us today!

Recommended Customer Reviews
Sheri T.I had Johnson plumbing come out to my house because my dishwasher was getting backed up with water. They checked under the sink and the dishwasher. He said the lines were fine and that
I needed a new dish washer.
I had only lived in my house 2 yrs and I know the dishwasher was less than 4 yrs old. The dish washer always worked and that wasn't the problem it was the back up of water that would cause concern for me.
When I ran the dishwasher the water would drain out. I figured that it was the air gap I didn't have( thank god for Google) instead of going out and spending $800 for a new dishwasher they suggested.
I had another person look at it and he changed the hose with a new one and added an air gap I didn't have. I'm so glad I had enough common sense not to go out and buy a new dishwasher. I would of had the same problem with the new one since it wasn't the dishwasher at all, I just needed a air gap.
I'm thankful I didn't get a new dishwasher and have to pay someone to install it. That would of been a huge expense on my part. So disappointed that they had no brains at all to figure out but I did.
I Google everything these days you have to or people take advantage of you cause they know you have no idea of what's going on.
Kristian M.Rude customer service. Impatient people working there. Asking clarification questions, and the lady had a rude tone of voice.
Olivia F.Mother recently passed and I took over her home. Had some serious plumbing issues and saw she contacted Johnson Plumbing before. They came out one evening and did quick work. They returned to give me a better idea and quote on fixing the issue(s). What a waste of time. I don't live in Merced and it was such a hassle trying to get any questions answered about what the real issue was.
Quoted me over $8,000-$15,000 to replace a pipe. So of course I called another company for another quote. My mom had been using Johnson Plumbing for who knows how long.
In 1 week, the other company gave me a quote and got the work completely done, for 1/3 of the price Johnson Plumbing quoted.
I give some stars because they were available to come out during an emergency, but took stars away because it was too much of a hassle to try to get to the root of the situation.
No wonder my mom called them often, they had a long term customer in her because they never really took care of the issues. In Merced, there are other plumbers available, get a 2nd quote/opinion and you'll see other companies want to help fix your issue not just keep you as a forever customer.
Called for service and they answered promptly. They were able to come out same day. They gave a 2 hour window and actually showed up in that time window. The tech was knowledgeable and helpful. Patient and responsive in answering my questions. And they got the job done! Highly recommend.
I have used Johnson's Plumbing for years. I've always got a great price and fast service. They changed out my entire drain from home to street in one day at a cost lower than any other. I have called them numerous times for plugged drains. Their response time is always within a few hours. Yesterday, the poor service guy was working in 100+ degree weather. He was nice. He completely cleaned the entire drain. And he cleaned the entire area before he left. Great Way To Keep Customers.
Very courteous, professional and reasonable. Fixed the problem with my shower when previous plumber abandoned job. Thank you!!
Diana C.I run a complex in Merced and Atwater and Johnsons is reliable, friendly and always there to get the job done!!!!
Teddi G.Jason was friendly and knowledgeable. He quickly replaced my old, dead garbage disposal with a new one. Works great! I am so pleased. Teddi in Merced.
I called for emergency services and I called Johnson plumbing. Talked with a lady that was really nice and gave her all our information to get a call back form the plumber that's on call. Plumber called back about 15min later which we felt was really fast But after hearing they wanted to charge 220 per hr with a 1.5 hour minimum. We where shocked and we will never call them back. I would hate to see what they charge during regular hours. I would recommend calling another company that is not going to price gouge you because they think they have you over a barrel.
thank you
Logan S.Just had my, 71 year, old main water line replaced by Johnson Plumbing. They are so fast and efficient. I highly recommend them.
