We had a plumbing emergency and called at 7:30am. He picked up his phone and made me feel at ease. He could tell I was stressed and said he'd move around his morning. I was so relieved! By 8:45am he was at my house and by 10am the problem was fixed!! Incredible customer service! read more

Very rude. just told me he was booked and sorry. hmm not even told me until when... i guess Kevin is no longer interested in new businesses. got it! moving on. read more

Kevin is a plumbing hero! Highly recommend. Quick to solve our problem, clean maintenance and very personable. Thanks so much!

We have known Kevin for 30 years. He is excellent at his craft! Most importantly, he is an honest, kind, and ethical. It is always a pleasure to receive a visit from Kevin, catch up, and admire his work! HIGHLY recommended! read more

Very professional, courteous, excellent price. Should have called him first before trying to unclog a blockage under the house. Would have saved me time, money, frustration, and an unhappy wife. Next time, just call Kevin first. read more

Kevin is a super kind person. He always goes above and beyond the call. He fixed my old janky toilet. --will need a new one soon. But he got it spiffed up and I can use it until I can afford a new one. read more

Wow! Kevin has saved our plumbing on three separate occasions! He is fast, reliable and always keeps costs down. We are so impressed with Kevin and what a good person he is! One in a million!!! read more

Kevin was amazing, super friendly and came on a Sunday when no one else would. Very affordable and helped get us flowing again in no time!

I'm a pretty handy DIY girl, but there are some things I just don't WANT to fix myself. Plumbing is one of those areas where I'd rather have someone else take care of it. Unfortunately, plumbing also an industry that seems to be filled with scam artists, at least from my experience. Maybe you've encountered the estimates that have no bearing on the enormous final bill (but what are you gonna do when your pipes are in pieces in front of you and they tell you it has tripled in price?) or work that is incomplete, shoddy, and even dangerous...only you don't know that until after they are long gone! Well, I don't have to worry about ANY of that with Diablo Rooter. Kevin (the owner) is honest, friendly, and practical. In my three years of using his service, I don't think I've ever called twice with the same kind of problem, so I've had a chance to test him on many things -- fixing broken pipes, repairing leaky faucets, clearing a toilet, installing a garbage disposal and faucet, clearing a sink line, and troubleshooting a faulty ice maker feed line. Today the line to my water heater sprung a leak and, while Kevin was around to fix that, I also had him clear a slow-running drain. He and Steve (who helps him out) are amazingly efficient and they were done in no time -- leaving me with a bill that was thankfully very reasonable. There's a danger in writing a Yelp review for a business you are loyal to -- they just might get so much business that they aren't available when you need them next time! That's the risk I'm willing to take with Kevin, because he is such a good guy and I think honest, competent people deserve all the business they want to take on. The world needs more reliable folks like these guys. read more

Wow. I was having one of the worst days of my life and almost completely broke, literally on the edge of a melt down, when Kevin came and fixed everything!!! I left for vacation a week ago on the same day my bathroom flooded with sewage water and I slipped and injured myself landing in that nasty stuff. I put towels over the mess and washed off the best I could before my 13 hour drive out of town. I returned to the same problem. I had previously used another company to a tone of nearly $230 just to clear my main drain. They saw sucker written on my head and pulled the rug out from under me. I had never needed a plumber before. So you live and you learn I guess is the lesson here. Hopefully you read this and skip the expensive part of your lesson. After being ripped off by the other company, who then told me that my plumbing was backwards and they could fix it for 10,000 bucks, LMAO, I then went the ultra cheapo route and rented a drain snake from Home Depot for $65 which did nothing but frustrate me, make my clothes and car stink and me feel even more like a failure. This is when I made one of the best calls of my life! I called Kevin at Diablo Rooter who came out and cleared my main drain very, very thoroughly and even cleaned my bathroom sink with a mini drain snake at no extra charge. He was over 3 times cheaper than his competition and was unbelievably nice about it. I overheard him on the phone talking to another customer who called. He explained that he could not get to her today but he could recommend people and if they were busy to call him back and he would try to make it work but not to call a random person out of the phone book. That there are too many phony rip off artists out there. I myself am the collateral damage of this very thing that is giving plumbers a bad name. Thank god there are still some people like Kevin at Diablo Rooter out there! Thank you so much Kevin!!! read more

So we bought this Rat Pack-style home in the 'burbs. When we turned on the washing machine after hooking it up, the faucets leaked all over. Found Kevin on Yelp, and he came over the day after Christmas. Nice, quick, easy, priced right. He kept telling us to call him if anything came up. Well, I was happily doing laundry that night when I realized that the clothes coming out of the washer were smoking hot. Being a suburban mom of two, my clothing generally isn't described as "smoking hot", but it clearly was. I called him, and he walked me through a couple things over the phone to diagnose the issue. Then he came back early the next morning and fixed it at no charge -- even though the issues weren't related to the original problem (the hoses were hooked up in reverse order and one was clogged). That's what I call good service. Sadly, my wardrobe has reverted to its normal lukewarm mode. read more

My parents needed a new garbage disposal (at least they were told by their building maintenance guy that they did), and they referred me to Diablo Rooter. Kevin returned my phone call within minutes, and gave a fair quote to replace the disposal. When he got to the apartment, we found out that the disposal didn't need replacement, but was only stuck. So, he didn't replace the disposal and saved my over $100. He easily could have replaced the disposal anyway and made more money., and no one would have been the wiser. Now THAT's honesty. To me, that's the most valuable trait in a tradesman. read more

These are the guys you want to call. We've called Kevin out a couple of times now and he's been fast, professional and courteous both times. The first time he cleared our main sewer line for less than half of what I paid RotoRooter a few years ago. In addition he warrantied his work for six months. When we called him back to clear our blocked tub and he brought his son with him. They spent a fair amount of time diagnosing the problem and cleared the line. In addition he re-snaked our main line again at no extra charge. He told my wife to write the check out to son since he's heading off to college. It's a true family operation. Definitely good folks who will continue to be our go-to for plumbing issues. read more

Another satisfied customer of Diablo Rooter! When I initially called, Kevin was very friendly and let me know he was on a job but would call back as soon as possible. True to his word, I heard back from him within an hour and he was able to come out as soon as his schedule allowed. He was really good about not having me wait around and was prompt. As far as the work done, I was extremely impressed. We had a leaky sink and a toilet that would constantly run. I've tried to replace flappers in the past with less than impressive results, so I knew better than to try. Within an hour Kevin had replaced the sink and flapper while taking the time to explain what he was doing and why it was necessary. He also had a number of sinks on hand and let me make the choice based on price and his recommendation. His rate on the sink was more than fair, I think better than what I would get at Home Depot. There was none of this adding in extra charges through markup. I'm not looking forward to future plumbing problems, but when I do I'll be giving Diablo Rooter and Kevin a call. read more

I called this company based on other yelp reviewers. The owner, Kevin, is very prompt & good. He does his work quietly and no over rated charges. Before I called Diablo Rooter, I had inquired with 3 other plumbing contractors for an estimate. I got the best rates from Diablo Rooter and so I decided to try this company. My decision was a success; hence I give 5 stars. Hope this one more good review for Diablo Rooter will help another yelp member to make the best choice without hesitation. read more

Had a great experience with Kevin from Diablo Rooter. Impeccable service and reasonable. Very reliable, the fact that it's so hard to find an honest and reliable plumber. I would highly recommend Kevin from Diablo Rooter. He fix the problem in 15 mins. read more

Diablo Rooter is based out of Concord and is owned by Kevin Moeller. Even though I live outside of Kevin's service area, he came to my house and worked on some small plumbing jobs that I had. He is clean, courteous and very professional. I liked Kevin over the plumber that I've used for several years because he (1) gets right to the job (2) doesn't talk too much and (3) his rates are very competitive. It was nice to get simple, straightforward service. I would recommend anyone to call Kevin! read more

Excellent, quick, and reasonably priced sewer clean-out service. Called at 6:30AM, after discovering a back-up in our line from the house to the city sewer (110-feet). Kevin answered the phone, and said he would be by after 9AM. A slight delay led to a 9:30 arrival, which he called to tell me about. He arrived in a well-equipped van, with what looked like the right tools. He was done in 20-minutes, or so. He suggested flushing all the toilets and running the water to make sure all was working fine. He pointed out where the blockage occurred (about 100-feet from house). He provided a receipt. Cost for the house call and service totaled $110. He worked alone, and he was very polite. 10:15AM and he is gone. I highly recommend him. And, thank you Yelp for being there. The thought of calling a Yellow Pages add and having some creep come out and over-charge us for lousy service is un-nerving. Yelp is a life saver for these kind of things. read more

Contacted Diablo Rooter to look at our damaged outdoor hose bib and within a few minutes after leaving a message, Kevin called back and scheduled an appointment to look at the problem first thing the very next morning. Once he arrived, he knew exactly what to do and within an hour was able to replace the very old compression fitting with two new, sturdy threaded hose bib connections. Prices were very reasonable, he used quality materials and provided excellent work along with stellar customer service. Highly recommend to anyone in the area needing plumbing services! read more

We had a blocked sewer line that needed emergency service. I called Diablo Rooter and asked if they could come the same day. Kevin responded to my phone message within 5 minutes as promised, then sent a crew to the house in about an hour and a half (after they finished a job already in progress). The guys were professional, courteous, knowledgeable and fast. They cleared the line in about an hour and were on their way. I would recommend Diablo Rooter to anyone and will definitely be using them if I have any more plumbing issues. read more

A plus service. Kevin is SUPER polite, very friendly, and he fixed my clogged sink AND the screwed up water pressure as a bonus. I recommend and would hire him again in a New York minute. read more

Long story short, a drunk driver crashed into the main water valve outside the house. The police came and swept the driver and her car off and the EBMUD shut the main water valve off that night because of the broken pipes and spouting water. And our home with 2 adults and 3 children had no running water. Of course it was a Friday night, so the very next morning I started calling every plumber that serviced the Walnut Creek area without much luck. Most of them were happy to come out first thing Monday morning, or were half asleep, or were just too busy at the moment to do the job that day. Luckily I spoke to a very polite gentleman named Kevin who was also busy that day but was willing to make some time that afternoon to assess the damage and to see what he was able to do. He came out that afternoon, evaluated the damage, and in a completely calm and professional manner, explained everything that needed to be done and why. Within 2 hours, he had everything fixed. What a relief! It's just not often that you run into a person like this---hard working, professional, kind, honest and reasonably priced--- and I couldn't appreciate it more. I wouldn't hesitate recommending Diablo Rooter to anyone and everyone! read more

These guys are great. Another service company had left us in the lurch and Diablo Rooter rode to our rescue. Even though it was late in the day, once I explained that my wife's chemo made a working toilet even more necessary than usual, they promised not to end their day until they fixed it. Within an hour they were at our door and 20 minutes later, everything was good. A great, fair price. Fantastic service. Nice people. Diablo Rooter is our new go-to company for plumbing problems. read more

Kevin did an awesome job fixing a pipe in my bathroom. He was very honest and didn't try to upsell me on anything. Very nice guy. I'll definitely use him again! read more

I bought a fixer house, moved in, found out the drains were clogged. Called these guys, they showed up in one hour, wham, bam, in-n-out. They got things running again lickety-split. Really perfessional and fast. When you need a fast and friendly rooter, these are the guys to call. read more

When I first moved to Walnut Creek, I needed a good plumber. I checked out Yelp! and saw the great reviews for Kevin and thought I'd give it a shot. So SO glad I did! It's now 8+ years later and whenever we have a plumbing issue, we are confident that Kevin will take good care of us. So friendly, professional, polite--all of those things for sure, and also, an EXCELLENT plumber. I only wish our contractor's plumber had been half as competent as Kevin when we did our remodel. If you are looking for an excellent, responsive plumber, Kevin is a great choice! read more

Kevin came within the hour of calling him (on a SUNDAY). He was affordable, quick and has a 3-month guarantee in case our sewage back-up happens again. Would definitely recommend Kevin! read more

Kevin was straightforward and efficient. He immediately diagnosed the leaky sink drain and had the old pipes out and replaced in no time. Highly recommended! read more

I called half a dozen people before I booked with Kevin. He was very professional and courteous. Everything we needed was taken care of quickly and very affordable. While I hope I won't need him, he will definitely be my first call for any future plumbing needs!!! Thank you, Kevin! My family is so grateful! read more

My new go-to guy. Kevin was at my house in 30 minutes. In a world of corporate high priced fleets and unlicensed operators, its the independent licensed and bonded guy that gets my business. Quick, decisive work at a very affordable price. read more

This is a example of a company that emphasizes, customer service! My family had a plumbing issue that had been a reoccurring problem. We had in the past called on services with other contractors to fix our issue. Our problem never got fixed. So this became a repeat problem. I called Kevin of Diablo Rooter. He was polite and honest to the point. He made room in his busy schedule to help us. When he arrived he found the issues and explain the problem. He was budget friendly. He was a great experience. If you need a plumber, please use Diablo Rooter and you will not be disappointed. Kudos to Kevin. read more

Kevin was awesome, great customer service, and was able to address our problem within hours versus the big brand names which only gave a 4 hour window. Will definitely be using only Kevin for our plumbing needs going forward!!! read more

Kevin has been servicing my dad's house for years. Recently the sewer line backed up and he was out there on short notice. We really appreciated the quick response. He's honest, reasonable, and reliable! read more

Kevin is a consummate professional. He showed up on a Sunday just two hours after we called. He was polite, respectful, and was in and out with problem solved in under half an hour. We paid a pittiance of what we had feared to pay when our sewer line clogged up. I will call him again in an instant if I have any other issues in the future. read more

I've dealt with several plumbers, and Kevin is the best of all of them. Hands down, no contest. He tells us the truth about when he's coming, if he can come sooner, which has happened more than once, he calls and comes over. His work is high quality, and his price is always reasonable. If you're in central Contra Costa, look no further. He's the best, and has saved our family multiple times. read more

Just good words about Kevin. I have a problem with my next door neighbors tree, it clogs my drain every two years. I had another company for a while then I got the ol well we need to do trying to make a small job into a big one. to top it off the guy did a SH*& job problem back in 3 months. Called Keven came in did the job in minutes and fixed a sink and the cost was less then the other guy. I was impressed read more

This guy is awesome. SUPER-polite, both on the phone and in person. He called me 10 minutes before he arrived to check that the time still worked for us. Extremely knowledgeable about his craft. Our shower was not regulating temperature properly - it was either freezing cold or scalding hot. Kevin fixed it in less than an hour, and fixed the toilet seat (which was loose) for free. It was a pleasure talking with him while he worked. He obviously loves his job. He was much cheaper than Lett's, which was the other place I called. If we ever have plumbing issues again, I will definitely call Diablo Rooter. read more

Immediate. Responsive. Friendly. Competent and helpful. The clog was resolved in a couple of hours when others could not arrive for days. No problems since. read more

Very pleased with the service. Called him at 6:00 pm and he showed up at 7:30 am the next day. He and his son are very professional, extremely friendly and they took care of the problem quickly and for a fair price. We will definitely call them again. read more

As the 5-star rating suggests...As good as it gets! My sewer line was clogged and spilling out into the yard (not pretty). I snaked it myself about a month ago. My wife pointed out that doing it twice would be more expensive than having someone do it who would guarantee the work. I called and Kevin and was pleased someone answered straight away. He was polite, helpful and gave me his price - no waffling. I inquired about getting a video down the sewer. He doesn't do that but gave me a number of someone who does. I then called three other places as standard practice and they were all either more expensive or gave the 'we can't give you a price over the phone' type of answer. I called back and Kevin said he'd be there in an hour. The best part of the experience was actually having him onsite. A decent man, humble and expert at what he does. Great experience and great price. I asked for one of those magnetic business card and told my wife that this is the guy to call for any of our plumbing needs from here on out! read more
