Company Overview
Since its inception in 1960, Johnson Plumbing has been delivering reliable plumbing solutions for residential and commercial needs. We cater to the plumbing needs of residents in Merced and Mariposa counties, California. Our offerings include a wide range of plumbing fixtures and products, such as swamp coolers, water heaters, and systems for water purification and softening. Our inventory features products from leading brands such as Kohler, Moen, American Standard, Price Pfister, Delta, Eljer, Chicago Faucets, and Zern. Our expertise lies in the installation and repair of toilets, gas lines, faucets, disposals, and grease traps. We offer video pipe inspection, leak detection, root removal, and replacement services.

The business started as Sid Johnson Plumbing from 1960 until 1972, when it became Johnson Plumbing with the full-time involvement of Greg Johnson, our current president. In 1981, we took the step to incorporate, becoming Johnson Plumbing, Inc. Initially focused on new construction, we shifted our focus to service work in 2000; if it involves gas, water, or drains, we handle it and are fully licensed and bonded. Scott Johnson represents the third generation working here, and his son Andrew is set to join us this summer, marking the fourth generation. We boast a great team with a lot of expertise!

Hello, 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. I even remember my first show-and-tell in first grade was about a thermocouple for 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 in those days; I was the backhoe! I thought trenchers were a myth until my dad hired one; I wondered why I was digging by hand! I like to think he was shaping my character. He was recognized for being fair and honest; I hope we continue that tradition. He was the hardest worker you could find, and I take pride in being his son. I went full-time after high school, married a wonderful woman named Sharon Fauver, and we have two boys, each with four kids. We cherish them all. Call us today!

Recommended Customer Reviews

Great service
First time with a plumbing issue.
Arrived in less than one hour
Sent 2 guys, both very professional and polite.
I highly recommend.

Great reliable service very professional and upfront on what the trouble is and gives you an honest account of costs. Great job done.

I am president of our homeowners association, so I'm in charge of contracting services such as plumbers. We have used Johnson Plumbing for over 20 years. One reason we keep using them is that they respond promptly to emergencies. The majority of our calls are emergencies so we need someone that can respond immediately. Also, it is useful that one of their technicians, Ruben, has been with them for so long that he knows our plumbing system very well.

There was some miscommunication about the pricing, but overall I am pleased with their work. They are very responsive, professional, and patient. The technician was able to identify the problem quickly and had all the materials on-hand to fix my toilet. I would use Johnson Plumbing again. They also accept electronic payments.

Johnson Plumbing listened to my service request and were able to get the job done in 2 hours. Thank you.

Once again had plumbing issues, capped Johnson's Plumbing. Joe arrived within 45 minutes and had us up and flowing. Joe was fast, courteous and friendly. Johnson's Plumbing is our go to..

We recently bought a house in Merced, there was a leak in 1 of my sink(bad work from previous people) and need our toilets re installed, Called Johnson plumbing for this jobs on separate dates, 1st time they come and fixed it next day, 2nd time, the same day, very nice and professional, they do a really good job, i felt that it was a little pricey, but to be fair: I am not familiar with the rates on this jobs, also you pay for what you get and I got a good service, will call them again if I need them.

Had an issue with sewer line, called and they came out right away. The techs were friendly and took care of the issue right away. They even showed up a little earlier which was great. They cleaned up the area and left no trace. We would definitely call them again.

Oh please Mr. President. I don't dispute the
hour minimum or the minimum money charged.
It's the work ethic to not
fulfill the hour for a hours work.
My understanding is billing is not a flat rate per job
but strictly time and material after first hour.
Did I miss something?
Billed for an hour yet completed job in 22 minutes and
didn't ask if I had any other issues to fill the hour.

Gas leak in wall near fireplace... Manuel Silva did a great job finding the problem and fixing it in a timely manner...thank you
