I hail from Novato, I started my plumbing career in the year 1996.
Frustrated with the larger companies in Marin, I founded my company in Novato in 2002, after leaving a local company.
At that point, I already had 6 years experience in both plumbing and heating.
With my new venture, my dedicated clientele that had been with me for years remained loyal.
I always wear a belt - haha! :)
Bill Johnson, hold a plumbing contractor license with 19+ years of experience in Marin & Sonoma counties. I prefer the old school way of doing business - you call, I respond (or respond swiftly). Once we schedule a time, I will show up at the time we agree upon, set to tackle the job. Simple!
I operate the company myself, & I don’t have a team, & I don’t have a fleet. There is no receptionist at Bill Johnson Plumbing, there's just me. This means I arrive ready, ready to tackle the plumbing need. I believe you’ll be pleased with the outcome, so give me a try!
I was born in Belgium, I come from a military family. My father served in the Army, and I lived my first 12 years in West Berlin, Germany. Prior to the wall’s collapse!
In 1980, my family moved to Novato, CA, and I’ve called that area home ever since. Currently, I reside in American Canyon, CA.
In 2002, the year I started my business, I met my wonderful wife, and in 2004, my son was born. In 2008, I had a beautiful daughter. In 2010, I got my life in order, and married my gal, and acquired a house.
Now, I just work, and enjoy time with my family as much as I can!

Best plumber ever!!! SERIOUSLY. Bills work is amazing. He is friendly,prompt and quick . U can trust that he does quality work and is very very fair in pricing. we have used Bill for all of our plumbing needs in the past because of how great he is. I had an issue with our sink and had and estimate from another plumbing company because this was kinda an emergency and they quoted me almost $1000 to fix it. I called bill right away and he was available fix our issue for a hell of a lot cheaper. Bill is reliable and the work is top notch. If u need an honest plumber don't go to anyone else but Bill.

Honest. Responsive and does GREAT work. He takes time to work out the issues and looks for solutions.

OK....it's official!!...Bill has earned his 5th star. Got the little notice from the City (Vallejo) that our water usage had tripled. Sure enough, with a quick call to Bill, we were able to calmly ferret out the broken pipe causing the problem. Couldn't believe how Bill made the time to
temporarily stem the flow with a shut-off valve, to buy us time till the Spring/Summer to fashion a permanent fix. We will be seeing him then!!! I have recently had occasion to refer three people, who had plumber horror stories, to him. Thank you again Bill.

Bill has been fantastic in helping me get my plumbing (and other systems) up to snuff. He is friendly, fair and communicative. He goes over and beyond! When I needed to get a new faucet for my bathroom sink, he did all the research for the type of sinks that would work in our space, and sent them to me. Thank you Bill!

I am one hard-a$$ critic when it comes to finding good contractors, plumbers, electricians, etc. I have a rule of thumb to get at least 3 bids when dealing with jobs over $1000 (if it's not a dire emergency that is). Why? Because I've gotten such different ""estimates"" for the same exact job(s) to be done in the past. From a water heater replacement, to a furnace replacement, to even painting contractors - - bids coming in ""way"" off from the others (varying by hundreds to thousands of dollars).
Bill Johnson was one of the plumbers I called when my water heater was leaking from the top. I called 2-3 other plumbers as well. Bill was on vacation but returned my call (by text) within a short period of time, telling me when he'd be back, asking what the problem was, etc. (It was a holiday weekend so he didn't even need to do that, but he did). Long story short, I hired him to fix the w/h leak (as well as fixing the air gap/hose under the sink that was leaking). He was professional, honest, well spoken, clean cut, and he explained everything about the problem, had no problem answering my questions (or having me watch him work on the water heater). I have finally found a plumber I can happily say that I will use in the future. His pricing was extremely fair and his work was ""OCD"" perfect! I also love that with Bill being a one-man show, I won't have to worry about getting someone ""new"" or someone else coming out to do a job (like with bigger plumbing companies who send whoever is available that day). It's nice having one plumber who stands by his work and does a great job.Thank you, Bill Johnson.

I would definitely recommend Bill Johnson for any water heater repair. He's very easy to communicate with via text or over the phone. He knows what he's doing!!! And he has all the right contacts to get things done right...
We had an incident where our water heater was making a large boom sound and would rumble when we used hot water. I was able to take a video of the rumbling noise and sent it to him via text and he then advised me to call the company since we were still under warranty. He didn't want to waste our money with a visit if it was something that could be fixed by a simple phone call. Well, after I made the phone call it became apparent that we needed his expertise. He was able to see us the next day and call the right guys to be able to get the parts we needed without having to pay out of pocket; again, we are still under warranty, but the company wanted us to pay OOP first and then get reimbursed later. Whatever Bill did for us was awesome, nothing OOP and the part was replaced.
Well that helped fix part of the problem, once the first part was replaced, he discovered that another part needed to be ordered and replaced. We made another call to the company for the parts we needed, Bill was able to get the part (again nothing OOP) and he came as soon as he received the part and finally we have a quiet and working water heater!!!
Thank you so much Bill!! Definitely recommend!!

Bill is so great at his job, I think of him as the Titan of Plumbing! My Mom and I adore this man - he is skilled, professional, explains all the work to be done (in a way that doesn't make you feel like you're a dope) and ALWAYS gets the job done perfectly! He has installed my new O.A. Smith water heater, completely rebuilt my 3 Mansfield toilets (using Mansfield parts!) and most recently fixed a nasty leak from a Moen sink in our 3rd bath. There is nothing Bill can't do and he seems to always make time for us, which my Mom and I love. We like him so much, I invited him to join us for a Beef Stroganoff lunch (he preferred to keep working and turned me down, but I always appreciate his dedication and enthusiasm! For us, there is no one we trust or like more. You will never be disappointed, if you hire Bill!

I have used Bill's Plumbing 4 or 5 times since I found him in 2012. He has always returned my calls promptly, and he shows up on time with the right tools. He has accommodated my schedule every time. Look at some of the pictures he has on Facebook. Truly a professional. He doesn't charge enough for what he does. It doesn't get any better than this!

best plumber on planet earth! we live in american canyon..my mom lives in marin county and we use bill johnson exclusively! ! afordable..honest ...no nonsense. .supremely knowledgeable in his field. will not rip you off!

Bill Johnson was a pleasure to work with. I wanted to change out three old toilets. He gave me lots of advice and went to considerable trouble checking out available options for me. He installed my new toilets carefully, and adjusted for one uneven old tile floor so the toilet would sit properly.
He was fun to talk to, and certainly knew all the ins and outs of toilets and how they work.
