Originally known as Sid Johnson Plumbing from 1960 to 1972, the company rebranded to Johnson Plumbing when Greg Johnson, the current president, joined full-time. We incorporated in 1981, officially 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, our third-generation team member, will soon be joined by his son Andrew this summer, ushering in the fourth generation. We have a fantastic team with extensive knowledge!

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 took to it naturally, enjoying holding the flashlight and passing him tools and fittings. I recall my first show-and-tell in first grade was on a thermocouple that goes on a water heater! I started from the ground up as soon as I was able; you might call that a ditch digger, LOL. We didn’t have a backhoe back then; I was the backhoe! I had no idea they made trenchers until my dad hired one; I thought, why am I digging by hand? 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!

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

Joe came and checked out our water heater, let us know costs to repair or replace so we could make a decision. He was nice, professional and thorough! Also Johnson Plumbing was the only plumber I called that has an answering service to answer after calls that come in after hours--that was a huge plus! Another I called said leave a message then their mailbox was full! We will definitely be using them again! We plan to ask for Joe!

I called three times to request a repair for the same bathroom. The first time they charged me a little over $100 and it worked for about a week or so the next time they came for the same bathroom it worked for a couple of weeks but I paid a little over $100 they came today and he worked for a couple of hours and now it's $400 but it's the same bathroom And they're telling me that each time they worked on it it's a little different problem but it's the same bathroom. It seems like they would've found that problem when they first came. I understand that I need to pay for the work but I don't think they understand how that makes me feel like they're taking advantage of me, maybe other people have had been results but I haven't

Never use Johnson Plumbing under any circumstances! Johnson Plumbing take advantage of elderly people. Johnson Plumbing take advantage of Veterans. I called them out to repair/replace a copper hose running up to my mother's swamp cooler that had been leaking. Instead, they took pictures, stayed for 10 mins and charged my mother $126. They stated that the float was broken and that was the cause of the leak. We changed the float and the swamp cooler still leaked. I called the next morning with the same request, please repair/replace the cooper line due to it leaking. This time I was told the Swamp cooler needed to be replaced and the manger would call me later to discuss the issue. Not only did the manger never call me back, but I called another plumbing company that came out that same day, replaced the cooper line and now the swamp cooler runs perfectly! I gave Johnson Plumbing a chance to redeem themselves and make my mother whole, they were not interested. Johnson Plumbing clearly have no integrity.

Another good experience with Johnson Plumbing. I have a small rental house built in 1926, so everything is old. The tenants are fantastic, and I try to keep them happy. I have been using Johnson for various plumbing repairs for many years. Today it was a moderate leak at the shut-off valve for the service supply line. I emailed Johnson last night after closing, and this morning when I woke up, I found a technician was already in route to the house. The problem was repaired within an hour. They replaced the buried shut-off valve by extending the pipes to keep the valve above ground, so it is accessible and functional, and not subject to corrosion from being in the dirt. It's so refreshing to deal with a competent, reliable company. Always friendly, easy to communicate with, and quick to respond. They invoice me via email and take my payment online. Could not be more convenient.

The two gentlemen that came were very knowledgeable and efficient. The reason for our call was an issue regarding the line from the freezer (ice maker) to plumbing of the house.

Overcharged for time and supplies and our water pump still can't pump out water. Bad experience and wouldn't recommend for use.

I've never used a plumber in my 75 years. These guys did a great job. Diagnosed my shower leak to the shower head extension tube. Replaced it and leak tested it and the shower pan. They also recommended a guy to replace the soggy drywall. Who also did a great job.

We had such a problem trying to get a plumber to come out to fix our backup. We were recommended by another customer who was very satisfied with their work as well. They were having some problems while they were trying to fix the backup and they called 3 extra guys to come help. They came out and not only fixed our problem but provided GREAT service. It started pouring while they were here and they still kept working through it all. They also have super affordable prices! I highly recommend them!
