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 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 began at the bottom as soon as I could; you could say I was a ditch digger, LOL. We didn’t have a backhoe back then; 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. My dad was known for his fairness and honesty; I like to think we still operate that way. He was the hardest worker you could ever meet, and I’m proud to be 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!

I Called Johnson Plumbing because the sprayer hose on my kitchen sink had started leaking. I told them exactly what I needed. The plumber shows up, looks at the leak and says he can't repair it and doesn't have any parts. I was informed if I got the part they would return and replace it. The charge for the original visit was $106.00. A second charge of $106.00 would be required for the second visit for a total of $212.00 to replace a hose. I would have replaced it myself except I'm too old and stiff to crawl under the kitchen sink. I called Johnson Plumbing's office and got a quite snarky customer contact guy who said the first visit was to ""diagnose"" the problem ""just like at an Auto Repair Shop"" and the charge was required and non-negotiable. He said it with a smile you could hear. I got Lowe's to finish the project. I've included a picture of the ""hose requiring diagnosis"". It cost $106 to be told there was water leaking out of my sprayer hose. This company might be good for major plumbing jobs but for a small job - Forget it.
If you're a senior citizen with a small plumbing job, I would suggest you utilize another company.

Our drains were clogged and toilets were not flushing properly. I called them in the morning and they had someone out within 30-45 mins. The service tech was super knowledgeable & got everything done in less than hour. Their prices are affordable as well!

The toilet started to bubble and all of a sudden water was seeping up both toilets and bathtubs...AGHHH! We called Johnson plumbing and began to grab towels as quickly as possible. The fantastic crew at Johnson plumbing arrived within 2 hours of the phone call; well within the estimated time of arrival. The plumber, Brad, was polite and worked quickly to unclog the main and reseal the toilets. Just like that my Monday went from crappy to happy! Thanks, Johnson Plumbing.

I've been using Johnson Plumbing for a few years now and have never had any real issues with their service until recently. In September, the hot water pressure in my shower was having issues so I called Johnson. They sent a plumber over who had been to my home before. He determined that a part of the shower unit was clogged and that a new part would be needed. He said he would look for a new part for us and let us know. In the meantime he was able to partially unclog the piece which restored the pressure for the time being. A couple hundred bucks for his time. After a few weeks the shower started to clog again and we had still not heard back from Johnson's about the part. I called and talked to the their dispatcher who had no knowledge or record of the previous visit. They sent a new person over. This guy had no knowledge of the previous visit so we had to explain it all over again. By this time I had purchased a whole new shower head set with the intention of having them install it figuring it would solve the issue. I also requested that he take a look into a potential leak under the house since I had noticed some moisture in the ground outside. At this point he went under my house and started verbally expressing exasperation with profanity about the awful plumbing work that had been done before. This is with my wife being the one who was home at the time. He told her the work that had been done before was so bad down there that it could be up to $10K in repairs. He then proceeded to not install the new shower head unit, basically did what the previous guy did and partially unclog the part, charged us a few hundred bucks and left. His assessment of our plumbing situation alarmed my wife and upset me since it was Johnson plumbing who had done the previous work on our plumbing and never mentioned any issues before. I called to speak to a manager, got passed around to couple of guys who had no clue, then a woman told me the manager was on vacation. A few days later a manager called me, apologized for the confusion and said he'd personally look into the last serviceman's observations. He came to check on the house and address the initial issue, the shower head unit and hot water pressure which was clogged again with my request that the new unit be installed. Again, I was not home when they came, and again like the previous times he did basically the same thing the previous guys did and still did not install the new shower head and still asking for a couple hundred bucks for his time! When I asked why he didn't install the new unit, he said he was confused and didn't think I wanted him to do that. He apologized and said he would not charge me for this visit and said he would get an estimate me for the other issues as soon as possible. A couple weeks later they come back with a $4.5K estimate saying the entire hot water pipes needed to be replaced! I got a second opinion, got another plumber and the issues fixed for less than $1K, no leaks, my hot water pressure in my shower is stronger than ever, all without the need of putting in $4 grand of new lines. In the meantime I still keep getting an invoice from Johnson plumbing for their 3rd visit where they didn't do anything and which they said they would waive. These guys are clowns at best and crooks at worst. Don't call them.

I called Johnson Plumbing back in Sept 2019 for a rental property kitchen sink issue. They said I didn't need to be there, since they can fix the problem if needed, with cost estimate not to exceed certain limit. They went and inspected the issue, but was unable to determine the problem. Well, the problem came up again (Nov. 20), but this time the tenants had a video of the leak. When the technician came, he still was unable to duplicate the problem, but suggested that we replace the faucet, so it doesn't happen again. Because I was there at the location, I was able to make a decision at this time, unlike the last time, where I did not have the option to make that call. The rate quoted was fair, but not cheap, but they gave me a one year warranty on labor if it leaks again. I would recommend them, but be sure to be there when they are doing the inspection and giving you a quote.

This is our second time using Johnson Plumbing. We discovered a leak in the main line leading to our fairly new house. The leak appeared to be before the main shutoff valve to the house. I did not want to screw anything up, so we called Johnson Plumbing. It was late in the afternoon and the dispatcher promised to have someone out to address the problem the next morning at 9am. Jerry arrived right on time with a smile. He asked about the situation and got right to work. He diagnosed the issue within a minute, shut off the main water line and started to dig. Jerry had to leave the job site twice to retrieve equipment and the correct parts. He communicated with us each time so we wouldn't be left wondering. The whole process took less than 3 hours. The invoice was fair and easy to understand. Jerry presented himself as clean, friendly, and professional. I would highly recommend Jerry and Johnson Plumbing to my friends and neighbors.

I left a question to compare the cost, about clearing a sewer line of roots that has been an issue in the past. Johnson Plumbing answered first with a reasonable quote, so I called to schedule an appt. The person I spoke to said she'd call someone to go out to the address and that person would call me and let me know when he'd get there. An hour or so passed and my renters called to say the plumber was done, do I want them to pay him. I said no, they were supposed to call me first, but I'll head over there to write them a check. Plumber said the renters told him the plumbing gets plugged alot, I said it seems to be seasonal, happening in fall and spring, but it's been a problem for me and my neighbors for years; their problems ended when the city finally took out the tree on the edge of their property. Plumber said they could put a camera down the line, find the problem, and fix it. I asked for a price and said I'd schedule that for another time.
I didn't get the call I was waiting for from the plumber, so I don't know if the job was done in a timely manner. I would've liked to have met him at my rental and talked to him about the problems I've had with the sewer line clogging. The price the plumber gave me was a tiny bit over what I was quoted online, BUT it was a Saturday and they came and fixed the problem. The plumber was polite and professional.

Worst experience ever. They sent out an incompetent person who had no idea what he was doing. He said it would take three hours. He had to keep calling other people. It took six hours to fix a leak in a pipe outside and install two faucets. We notified the office of the problem. They charged us nearly $800! All because it took him twice as long because he didn't know what he was doing, and that didn't include the price of the faucets! I would never recommend them.
