OK.... here is an update. After the first repair (they showed up 2 hours late) and six months later, the sewage pipe out of the kitchen sink cracked and water leaked out, causing the cabinets and floors to get wet. I called Bel-Carlos and Craig showed up as he promised to, and did the repair free of charge. I offered give him money for doing the repair so promptly this time but he refused to take the money, saying that it was his job to take care of his repairs. I think he is overall a good, no-nonsense kind of guy. He might just be overwhelmed by the amount of work he has so he might not show up on time every time. But once he is there doing the repairs, he does give his 100% best. read more

Worst experience with a company I have ever had. Dont show up and Craig is so awful and nasty, don't ever use them.

These guys should not be driving this way on the freeway putting our lives at risk. I filmed this on August 14, 2026 at 2:22pm Southbound HWY 101 near Millbrae, Broadway Exit. I was shocked by the driver's appearance and reckless behavior. He looked far too old to be driving safely and seemed barely able to maintain control of the vehicle. Operating a vehicle so carelessly puts everyone on the street at serious risk, and I am surprised the company allows this! NOTE: They misspelled "PLUMBING" on their van. read more

Have had bel Carlos out multiple times to clear out our clean out in the yard from over grown tree roots. He's also cleaned out our clogged shower and made it work perfect. He's replaced 2 water heaters for us over the last 20 years. Very reasonable prices and he does a great job! read more

I agree, an excellent plumber, but a con-artist when it comes to paying his workers for the hard work and sacrifice labored. Also, the owner might not be ok around children... sex plays too much even after requested numerous times to stop. The owner, craig costellato, knew about the labor board doing nothing over $300.00 . He definitely premeditated this, because he got a full 8 hours of work out of me before sending me away with no paycheck. Under the table is an understatement for craig cost-a-lot-owe. read more

This guy is the best around and i would recommend to anyone with any type of plumbing/water heater issue. I have used Bel-Carlos plumbing more than once and i am very happy with the results. read more

Cuidado con el , es un estafador y además de ser una de las peores que eh conocido Es demasiado grosero , tuve la mala suerte de conocer a craig y si puedo darles in consejo busquen a otra compañía de plomeria read more

BEWARE OF THIS CREEP!! I never write reviews, and I created a yelp account for the sole purpose of reviewing this company. If I could give 0 stars I would. Not only did it take three reschedules to get Craig out to our home, he was incredibly sexist, racist, and rude. He said very inappropriate things to me due to the fact I'm a woman, and he used slurs while talking about my Asian husband TO ME. On top of his rude behavior, his entire buttcrack was out in front of our small children! When my husband politely tried to ask him to pull his pants up in front of the kids he started spewing cuss words at him and screaming at the top of his lungs. As for the work done, he was at our home for much longer than anticipated(think weeks instead of days,) caused $10,000 in damages, and we ended up having to hire another (amazing) plumber to fix it (Regina Plumbing in RWC.) I would never, EVER let this man near my family or home again. BELIEVE THE NEGATIVE YELP REVIEWS!! read more

I was driving at full speed on El Camino Real in the right lane. Left lane was open. The Bel Carlos plumbing truck turned left into the far right lane at high speed. I had to slam on my brakes to avoid a high impact collision that would have resulted in significant damage and likely injury to one of us. I laid on the horn. I called their number later to report this, and the driver happened to answer. All I was able to get out was, "Is this Bel Carlos plumbing?" and I got a rant in which every other word was the f-bomb. Didn't even bother to ask who I was. How people drive and respond to others reveals a lot about their character. Would you want to do business with someone who is reckless, inconsiderate, and has an anger problem? Looks like Jonas L had a similar problem. read more

Our water heater went out and Craig came to the rescue! He did an amazing job. He cares and has passion for his work. This showed by how much better his work was compared to the work done previously on the old water heater. He is extremely experienced and will give provide you details on what he is doing and why. Thank you Craig!! read more

See all

Do not recommend this guy! Absolutely rude and unprofessional and disrespectful! Just don't! read more

Craig fixed a main drain clog that others couldn't! I called and he was there in 2hrs. He's been plumbing for decades. Very knowledgeable!!

Owner himself came and gave us a quote very quickly after we called. Tried Yelp's recommendations and most places won't give estimate without coming out but appointments just to give estimate will be longer time than Bel-Carlos to fix our plumbing problem already! And one quote we get from Yelp was higher than Bel-Carlos. Of course we stuck with them (and a good friend recommended them). Owner came to fix our water pressure gauge and one thing... stay out of his way!!! He does not like onlookers. But he did an amazing job with the final product! We were very satisfied. He is obviously VERY EXPERIENCED in doing plumbing jobs. He even went through the house and check the water pressure of all our faucets and shower heads to check the pressure inside the house. Overall, besides the owner's "gruffness", I would have given 5++++ stars! Will be calling him for any of my plumbing problem without doubt in the future (hopefully not again but who knows?) read more

The morning we were scheduled to leave the country for vacation we got a leak alert on an app we had installed that we were losing 1/2 a gallon a minute of water. After turning off the water to the house to no avail we determined it was a a major leak in the water service from the water meter at the curb to the house. We called Craig in a panic and he was here in less than an hour. He assured us he would take care of the problem while we were gone and to go on our trip and not to worry. He communicated with the city and gave us progress reports overseas while we were gone. He absolutely was a lifesaver and allowed us to enjoy our vacation. We came home to a perfectly completed job and a spotless job. We will trust Craig for all of our plumbing needs in the future. A++ read more

Craig didn't show up for multiple appointments even after confirmation by text. He offered no explanation for this!! read more

We had to eventually fix our mainline pipe since it was inevitable (gut out the drive way, replace the pipes from house to the city line, the whole thing). ...quite the project. Craig gave us a thorough plan from start to finish, and gave me updates any time the plan needed modification. He takes pride in his work and it shows. He is also used to working with the city, so getting the permit, etc. was completed in a snap. The strict city inspector came and went to review Craig's work. If you have emergency mainline back-ups or need to re-do your pipes, give Craig a call! read more

WATCH OUT! Craig is not only rude as hell but he is scammer. He will make you replace unnecessary items just so he can make some extra cash. If a section of pipe needs replacing, he wont just do the section alone. He will tell you ALL the piping needs replacing. Also he lies about having products at his "shop" which i believe doesnt even exist, he gets all his products from home depot. He replaced a water heater at my house and must have not noticed that the receipt was taped to warranty. It doesnt bug me that much, but he lied about it. Also the way he disrespects his employees is completely unprofessional, i could hear him calling a worker an idiot and other displrespectful things that i do not wish to repeat. He does good work but id rather give my money to someone who is respectful and doesnt lie. I wouldnt reccomend him at all. read more

Called and left him a message regarding my issues. Two weeks passed and still no communication at all. What kind of business is it?

Summary: Save yourself $150 and call a real plumber! These guys are either poor excuses for plumbers or total scam artists. The Delay: Thursday morning at 7am, I called Bel-Carlos Plumbing to check out a plumbing problem; I had no hot water throughout my house. The receptionist told me that their crews were out on on emergency calls that morning and would be able to come by a little after noon. So, I waited patiently all morning and decided to give them another call at 1pm just to check their status. This time, the receptionist told me they would be able to make it over in a couple of hours. It's now 4:30 and I decide to call again because I was concerned that they might have forgotten about me. The receptionist assured me they were now on their way over. Finally at around 4:45pm, they arrive! I took a PTO day for this! I could have went to work and dealt with this when I got home if I knew it would have taken all day! The Arrival: As I open the garage door, in walks Craig Coccellato (Owner of Bel-Carlos Plumbing). Craig aka "Butt-crack Bandit" shakes my hand without telling me his name, then heads right over to the water heater. I'm thinking to myself, Uh...okay...thanks for introducing yourself buddy. By the way, you'll see where he gets the nick name once he starts reaching for things and his shirt makes its upward migration. The Crack Gets Shady: Craig starts going to work on my 4 year old water heater as I explain to him that I have no hot water in the house. He tested both inlet and outlet nipples on my water heater, replaced ONLY the outlet nipple, and in 15 minutes later comes to the conclusion that my 4 year old water heater needs to be replaced. Oh, by the way, did I mention that my water heater was only 4 years old? Hmm, why didn't he replace the inlet nipple? We'll come back to this later. This diagnosis cost me $150! Shady Negotiations: Here's where he tries to gank me. To replace my water heater, he quoted me $1100 if I decide to go with his Bradford White model or $400 for installation if I provide my own water heater. Although, by this time of the day, its too late start on this job and the earliest that it can be done is tomorrow. My decision now is to see if I can get GE to warranty my current heater and save money. The Following Day: I spend all morning contacting GE Tech support about getting my water heater replaced. I must have spoken to at least 8 different GE Reps and 1 manager about my issue. They all tell me that my water heater is still under warranty but will not agree to replace it until they are able to confirm with the plumber that this heater is indeed broken. I call Bel-Carlos Plumbing several times trying to get Craig to call GE Support. Craig relayed a message to me through his receptionist (Veronica) that it was my responsibility to deal with warranty issues and not his. Luckily for me, Veronica was nice and helpful enough to get on several conference calls with me and GE Support. Veronica spoke with GE and tried to convince them that Craig used all of his plumbing experience to come to his conclusion that my heater was bad. Still, GE would not budge. "Sir, there is nothing wrong with your water heater. As long as there is good water flow into the tank and nothing obstructing the outflow, your water heater is not the problem." The Solution: Okay, its been 4 days now of no hot water. What to do? The options I have at this point are to hire Craig, call another plumber, or pick up a new water heater and install it myself. After consulting with my friend's brother (Paul) who is also a plumber, I decided to have him come out to give me a second opinion. Paul came by, checked out my water heater, and in 5 minutes diagnosed and fixed my problem. The inlet nipple on my water heater had a stuck backflow valve and there was weak water flow going into my water heater. AH HAH! So, this is why Craig did not replace the inlet nipple! It would have fixed the problem! I have a message for you Craig "You are a dishonest fucking asshole!" If you need a good plumber, I recommend calling Paul Gutierrez: 415-412-3727 USEFUL TIP: Scroll to the last review below and click the FILTERED link to unlock the TRUTH! 4.5 Stars...Ummm....ya. read more

I never do review but this guy Craig deserve my review!!!! Do not use his service .. He is rude never show up. I call him to follow up he yell at me and said I told you I will call you I have another job and then he hung up on me. Who does that !!! What kind of business is this !! read more

Craig is the best he helped us fix every plumbing issue in our house for a very affordable rate is highly recommended.

I will never use this guy again.Mister no show.He is so unreliable. Called him over and over regarding a leak in my front yard.He said he'd be out to fix the leak. Totally ignored my phone calls. Had to call out another plumber THANK GOD they came out within an hour to fix my leak. STAY AWAY FROM THIS GUY read more

Craig has saved our butts on numerous occasions from coming to our rescue on Thanksgiving with a full house of guests and a backed up sink to appearing with us in Small Claims Court when we had to sue our counter-top contractor for screwing up. He has also helped us out in choosing the right fixtures. He really has an eye for quality and durability. read more

Thank you, Yelpers, for leading us to Craig! We needed our water heater replaced and we met four different plumbers to get estimates. Craig was the one we liked the best, trusted the most, and hired to do the work. Craig squeezed us in, which we really appreciated, since our water heater was leaking and needed to be replaced quickly. He did a great job, everything was top-quality parts and cleanly done. They cleaned up before they left, which was also nice. His bid was reasonably-priced and included the cost of city permits (which he arranged for us, including the inspection). We would definitely hire Craig again for our future plumbing needs. He has a ton of experience and really knows what he's doing. read more

I gave them a second chance; this time to install a new toilet and everything went fine. First time, plumber was late and started at 12:20 (he got lost and called to find out how to get here at 12:00). It took him 40 minutes to install the faucet and I asked him to finish instaling my garbage disposal since I was paying by the hour. He finshed at 12:15, but I was charged for 90 minutes PLUS the garbage disposal was leaking within 30 minutes after he left (he used the wrong hose). I called and they allowed me to replace the check I had written with one MINUS 30 minutes labor...unnecessary effort on my part. read more

When I realized that my sewer line was clogged (on a Saturday night!), I dreaded having to make calls to various plumbers at 2-3x their already outrageous rates. So I YELPed. Thanks to all the Yelpers reviews! Called the first plumber and was quoted $250 - $325 plus I would have to wait until Monday. Then I called Bel-Carlos. Quoted me $160 and would be would be here in 2 hrs. He was right on time and got the job done. He reset my toilet and replaced flush mechanism in the tank for $50. It's Turbo now! In total he spent 3 1/2 hrs and got the job done. $210 out the door on a Sunday, Thank you Bel-Carlos Plumbing. I'm Happy. It's what I needed. I recommend his service...but just understand that he has a unique personality, and all will fine. read more

Super Craig to the rescue... again. "Craig was here" He will come. He will get straight to the task. He will not stop or waste time. He will get things fixed and if it requires more time he will get to it so the job is done. He will not fool or try to rip you off. He will CLEAN UP before he goes and for that matter he will clean up better than your housekeeper who has spend her entire life cleaning homes... When your plumbing is now perfect and your old problem area is now sparkling white glove check approval clean - everyone will know that... CRAIG WAS HERE! Call him. read more

Craig is a very experienced, knowledgeable, and hard-working plumber. We have been working with him for years and highly recommend him.

Craig and his team have helped us out twice. Last year we had a sewer line break, and Craig came out, diagnosed the problem with a video camera passed through the broken line, and showing us exactly what was wrong. They did a fantastic job getting the line replaced, and even helped us do a little remodeling of the affected bathroom, which now looks great. Needless to say, we were in a bind, but Craig worked with us calmly and got the problem fixed quickly and at a fair price. Last week we had a much more minor (thankfully) problem, but they were just as attentive to getting the job done right. We will definitely call them with our next plumbing issue! read more

Craig did a great job He was able to schedule me in the same day He finished in a timely manner Was very pleased Will use this company again read more

I had sewer work and a water heater replaced many years ago. After 14 years, a new one was put in. Today I noticed water around the base. Craig came out and checked it. Luckily it was just condensation due to these cold days. He did not even charge me for the service call. He knows his stuff and does good work that lasts for years. I highly recommend this company. read more

I don't usually write reviews, but this was not a good experience. Craig was across the street working on someone else's kitchen sink. He said he would come by and check out our plumbing issue after he was done. He stopped by a few hours later and we had everything ready for him to take a look at the pipe outside. In about 15 minutes he managed to completely destroy our garden, fix the pipe and then quoted us $200 dollars. He did not offer a "free quote" just got to work immediately, told me I "hovered", destroyed the garden, and said if we didn't pay him the full $200 we owed him he was going to take us to court and sue us for more. This guy is not nice...he fixed the drain but honestly it wasn't worth it. I wish I would have hired someone else. read more

We used Bel Carlos for several projects. In every case they have been fast, honest, and great to work with. First was a water heater that the bottom just fell out of one morning and flooded our garage. Bel Carlos was there within hours and by that afternoon we had a dried out garage and a new, working hot water heater. After that we decided to remodel our home. We discovered that we had old piping so we had Bel Carlos do a total copper repiping of our house, including adding a new shower, moving sinks and toilets around, and upgrading to recirculating hot water. Everything was terrific. We wouldn't hesitate to recommend Bel Carlos to anyone! read more

He came when he said he would and did the work and we haven't had any problems with the work he's done. He's a little rough around the edges but boy some of these reviewers are uptight. read more

I called them for an emergency at work and the guy they sent was really rude and obnoxious. He totally tried to rip us off! I got the work done for half their price. I guess they take advantage of folks in a bind. Shame on you! read more

Don't know what to think - after reading all these positive reviews, Bel-Carlos never showed up for appointment with me! :-( It went like this yesterday: 12:00 pm - called to make an appointment for 4 pm. Confirmed. 4:15 pm - called to check "The plumber is on his way" 5:10 pm - called to check again "Let us find out what happened ..." That's it, no call back ever again, no explanation, no apologies from Bel-Carlos. This morning called another plumber and the job has just been completed. read more

As a commercial property owner on the peninsula, I like to give my business to other businesses within my local area. I have had service over the years from most of the areas contractors and building services. Things do change in life and as we all should know, just because a company has been in business for a long time or under the same ownership, it is only as good as the new people they hire and he current service they perform. A company is only as good as it's last service call, (s)..... I was in the position of having to find a new pluming service. Contacted Bel-Carlos Plumbing and spoke directly to the owner Craig early in the morning as he picked up. Explained my position and requested a service. He made a 10 AM appointment but never showed up. I called back at 10:30 AM and was told that he got tied up on another call. Another first in the morning call? Hum... I was told he would be contacted and will call me back with an ETA, (estimated time of arrival), but he never did. I called back again 20 minutes later and was told he was on his way. He finally showed up at 11:20 AM with no explanation of why he was so late. I explained to him that I travelled to the location to provide access to the job and as I was offering a new account, found this initial meeting was not a first good impression. His attitude in response was not apologetic but rather dismissive. NOW HERE IS WHERE IT GETS GOOD..... His van looks nice and clean on the outside, but he himself looked pretty disheveled. I then asked him if he had a dog in the van with him? Perplexed, he said No! I responded by asking him why then does he have hair cuttings all around his neck and such hair matches his own? His expression was that of a child who just got caught with his hands in the fudge jar with fudge all over his face. The crushing moment of silence..... I then said to him, you let me wait while obviously getting a haircut before meeting me after making a confirmed appointment. Completely caught off guard he rudely said go get somebody else and wobbled away.... Although I wasted my morning on this guy, I had to shake my head and laugh at the caliber of this man. After reading the periodic reviews here on Yelp after the fact, one can see a pattern of attitude and performance. I was lucky in not having him provide any service. If he was my employee I would dismiss him and gladly pay the unemployment insurance just to get rid of him. Him being the owner of Bel-Carlos Plumbing, well that is inexcusable on every level. read more

Bel-Carlos Plumbing did not show up when promised. They didn't show up at all. No phone call. That's okay - I'm going to work my way through the long, long list of plumbers that serve this area and anyone who breaks their promise gets 1 star. read more

VERY DISAPPOINTED!!! I called Bel-Carlos Plumbing first thing in the morning with a pipe leak. They said they would send a plumber out around Noon. Noon comes and goes and no one shows up. I figure the plumber got held up a bit at his last job, so i wait. (A courtesy call would've been nice) Now it's 2:30pm and still no plumber, so I call Bel-Carlos back. The person contacts the plumber in the field and lets me know he should be arriving within one hour. I think as long as he shows up , it should be fine. 3:30pm and still no plumber... i give him the benefit of the doubt and wait a little longer... 4:00pm and again no plumber. I call Bel-Carlos and no one answers. 4:15pm and still no plumber. Call Bel-Carlos and again no answer. 5:00pm, 6:00pm... NADA So I basically waited all day for a plumber that NEVER came. The worst part is they never contacted me to explain or apologize... they just didn't show up. Not that day, not any day. No calls, nothing. If they had told me ahead of time they might not make it out, i would've tried other plumbers. Instead, now i have to take two days off instead of one. VERY UNPROFESSIONAL. I suggest everyone call someone else first and use these guys as a last resort. If i could give negative stars, i would. This was a horrible experience. read more

Showed up on time when he said he would, efficient work, and reasonable rates! What else could you ask for in a plumber. Oh and he was very courteous and nice as well. Left the bathroom very clean afterwards. Would recommend and very glad we used him. read more
