One Source was there to help me out in my time of dire need, and for that I am incredibly grateful. Cairo and team were incredibly responsive, even at very late hours into the night to make sure that I would be taken care of. You cannot go wrong giving them a call! read more

Owed this review to One source for a while. My toilet was 35 years old and died. It didn't flush anymore as the tank was completely busted. The overflow tube was done for and it would take forever to fill the tank. One source came once some 10 years ago to try to make it work, and they did, but this time they said it would just be better to get a Toto toilet (it would flush much better and faster). I asked how many days it would take to change it and they laughed, they said it would be out and the new one in in 60 mins flat. Wow. I know many people do their own plumbing, but I live in a condo and if I screw anything, I would be liable for insurance. So, decided to go for it. After agreeing on the next day, they came on time to SF downtown. they were clean and beats me, but they indeed took the toilet out and were out of my unit, including the old toilet in 60 mins. As a bonus, they also looked and fix an issue with my kitchen sink (it flooded). All within 1 hr. Highly recommend them! read more

I've used One Source Plumbing three times, and every time it's been an easy, professional experience. They have come out the next day, and fixed our plumbing issues in a timely and professional manner. I'd definitely recommend them if you need something fixed! read more

Called Mo with an emergency clog and he was on-site within 30 min and resolved the issue quickly. Great service experience!

OMG the best! Mo came out the same day to fix a problem, charged a very fair price and then had to take multiple calls after the service visit to calmly explain potential plumbing problems, what was causing them, and what a long-term fix would be. Mo took multiple calls and was always friendly and helpful. I would hire him in an instant again, and will refer him to all my realtor friends. read more

The water in my kitchen sink started backing up. I called a few places. Most were booked solid for days. One Source Plumbing And Rooter had an opening the next day in the morning. I checked in via text and Mo confirmed the appointment. He texted me when he was on his way. He came on time and got to work. Unfortunately Mo could not clear the clog. That in itself is not the problem. He did not charge me. He explained to me that the next step would probably involve working in the garage to undo the pipes and try to get at the clog from there. He even drew a diagram to show me where the clog is. In the end it seemed he was running late on time. He suggested I could possibly make another appointment or try another plumber. Okay fair. I understand that he was not prepared for more involved work, and probably had other appointments. After I came back to the kitchen I noticed he left a screw driver and dirty towels in my sink. Okay, whatever not a big deal. But when I looked inside the kitchen sink cabinet, I saw black stains everywhere. This must have happened when he was working and the water was backing up and spraying everywhere. He did briefly wipe the floor and the cabinet before he left, but that didn't do the job. I spent the next hour wiping and trying to buff out the stains. Honestly, I am not sure how one goes about protecting the cabinet when doing this kind of work. But I am not a plumber. Once dirty water like this hits any un-laminated rough or semi-rough surface, it's not possible to get rid of the stains. The truth is I have generic builder grade cabinets. But what if I had expensive new cabinets? I can see why most of the reviews are great. Maybe it was just bad luck. A bad day all around. The plumber that came after him, did manage to clear the clog. He did in fact get at the clog from the garage. When working in my unit, he used those industrial 50G plastic trash bags to completely cover the inside of the cabinet and the floor. When the black dirty water started spilling again, it went right into the bag without staining anything. In my garage he connected a hose to the water heater and hosed down the entire area where he worked. It was cleaner than before he started. read more

Best ability is availability and they're always available we manage multiple bars and always need service late night without someone trying to charge us an arm and a leg so we're grateful for their consistency (4years) read more

Called One Source at 9:18am this morning, Mo was at my house by 9:32am to fix a clogged toilet. Issue was fixed shortly there after. Service was beyond what I could have asked for! Thank you! read more

Mo was super professional and efficient. I had a big clog in the main sewage line so he had to remove my toilet and bring in the big snake. The problem was solved in 7 minutes, he put everything back in place, CLEANED everything and even replaced a broken screw in my bathtab (free of charge of course). Price was very fair and reasonable considering the work. Highly recommended! read more

I had a plumbing issue on a Sunday night and One Source was the only ones to actually answer after calling like 20 plumbers (many who listed themselves as 24 hours). Mostafa was very responsive, transparent, and punctual. When there was an issue with my building afterwards he went above and beyond to help. Would definitely call them again if I have a plumbing issue in the future. Thank you! read more

UPDATE for Covid era times: So, I went to make a few calls for an emergency plumbing problem last night but got ahold of Mo right away so didn't need to look any further. I remembered he was pretty awesome and super happy he picked up right away AND was able to come bright and early the next morning. Not only did he fix my issue at a good price but threw an extra part and repair for free because my toilet really needed it (?!?!) Wow. Such a nice guy!!! Honest, friendly, & reliable what more could you ask for? Well, as a bonus he and his assistant were decked out in all the proper protective gear and managed to make sure everybody being as safe as possible, maintaining the proper 6 foot distance and still making the visit feel friendly and personable. A great plumber to call no matter what but extra super to have someone safe and dependable in these crazy times! read more

When a water heater breaks, there's not a lot of time to do in-depth research for a new one. When my hot water heater died, the first person I called was Mo at One Source Plumbing. I've known Mo from previous jobs. He's professional, personable and very knowledgeable. Because I was under duress with water all over the basement, Mo was extraordinarily patient as I texted him with multiple questions. After exchanging more than a few texts and photos, we made an appointment for installation the next day. A great company, superior service and a genuinely nice guy! read more

One Source Plumbing is the best. They have done several jobs for us (cleared clogged sewer line, fixed clogged sinks/tubs, replaced hot water connector to dishwasher, installed new toilets, installed new hot water heater) and everything has been done well and at a fair price. Mo is super responsive and very patient about explaining the process for things, including our upcoming sewer line replacement. If I could give more than 5 stars I would. read more

Seriously the best service. Prompt and respectful. Saved my clogged sink. Cleaned up after themselves. Definitely will be calling them again if I have any plumbing needs. read more

They were quick, professional, and solved my clogged sink issue lightning fast. Can't recommend them highly enough read more

What can I say that hasn't already been said? Mo and his team are the BEST! I woke up to water pouring out of my water heaters overflow pipe and pan and didn't even know where to start. I called a couple of emergency plumbers but no one could come out that on the same day. Eventually, I connected with One Source and chatted with Mo. He had availability and set up a same day appointment. In the meantime, he also FaceTimed with me, diagnosed the problem and helped me figure out how to shut off the water valve. He followed up with a quote and reconfirmed the appointment. Mo and his colleague showed up ON TIME and immediately got to work. They were fast and efficient and even had a bit of extra time to take a look at my slow draining bathroom which they also fixed! One other small detail: I offered to tip Mo but he asked that I give the entire tip to his crew member. : ) To say I was impressed is an understatement. Highly recommend and Mo will always have my business! read more

It gives me no pleasure to write this review, but the fact is that a company that has bad customer service will not improve unless they understand that they will lose business if they don't make a change. That's why Yelp is where people turn for business recommendations, so they can find a place that is not only fix their problems but also leave them feeling good about it. I found the One Source Plumbing and Rooter lead plumber to be completely lacking in customer service skills. His technicians were both fine, respectful and careful. Their work was fine too. They had to return to re-repair a leak that they repaired last month, and it was during that visit that I finally lost my patience with the way I was treated. The property manager of my apartment hired One Source to fix a leak in my bathroom, the drain of the clawfoot tub, as well as the faucet stopper that feeds the shower attachment. I was surprised that when he fixed the drain, he added a drain that makes it difficult to place a stopper to draw a bath; it's a claw foot bathtub. It should be obvious that it's going to be used as a bathtub. But, I figured I could pick up a better one and replace it myself, rather than make them come back for something so simple. So. I got a chance to take a bath, very relaxing and one of my favorite ways to treat myself. But after I drained the bath I returned to the bathroom to find the floor flooded. What the heck! So I did some testing and found that although the repaired drain worked just fine when it's used for a shower, when a whole tub's worth of water is draining, the leak between the replacement pipe and the not-replaced floor pipe was so bad that most of the water ended up on the floor. I got back in touch with One Source and my property manager so they could come back and address this. On the appointed day, the service window was 9-11am. They showed up at 8:42am. I had let them know to call me so we could come down and let them in, because the doorbell was not working. But, I had to take a shower ahead of that, and I figured that jumping in the shower around 8:30 would give me plenty of time. Nope! They were early, so when I got out at 8:50am I had 5 missed calls and had a text from 8:45am that read, "We will wait outside for five minutes and then will have to reschedule two weeks from now." I'll be honest, I almost wrote back to say something like "cool, piss off then" but I'm an adult, so I texted "getting out of the shower" and between me and my son (he's 18), we let them in at 8:56am. Like, I get that it's never fun to wait outside like someone is playing a joke on you, but is it really that hard to say "Please let us in" without threatening to leave this issue unfixed for 2 more weeks? You already gave me a 2hr service window, what's your hurry?? Since the first visit had already been marked by a bad attitude on the part of the lead plumber, this visit was definitely not off to a good start. They came up, and I thanked them for their patience and mentioned that I didn't expect them to be early. He said it was fine and got to work testing the drain. They all kept their masks on, which is to be expected since they have to protect themselves from whatever germs might be hanging around inside my house as well as protect us from whatever germs they might be fighting off. I had put my mask on even though I was inside my own house, as a courtesy, even though I'm fully vaxd. But I also wanted to have my coffee and get a start to my workday. So I set myself up in our tiny outside space, just outside my kitchen. I guess I could have let them know I was going to be right outside my kitchen door, which I had left open, but I figured they would come looking for me before they left. Again, nope! After about 15-20 minutes I wondered if they were still at work and I went to check. They were gone. I was unnerved. I couldn't imagine why a worker would leave a house without taking leave of the head of household. This is such an ingrained expectation that I can't even put into words why it's expected. But I ask you, dear reader, would you feel good about it if you came to where multiple people had been working on some part of your house only to find it deserted? It's a thief that sneaks out of a house, not an upstanding member of a community. (Big house parties don't count, obviously, you can't always find your host when you have to leave.) So I called him. It was awkward; I asked what the end result was and he explained. Then I said, I was surprised that he had left without finding me. He said he had touched base with my son before leaving. Well, what he meant was he said goodbye to my kid on his way out -- I didn't find that out until later -- so when I started to explain how that wasn't adequate, he cut me off with a very defensive response. I ended the phone call shortly after that. I would not recommend this establishment. I hope this guy learns to check his attitude. read more

I had Mo and one of his crew install a sink, faucet and garbage disposal. They arrived early, worked swiftly and efficiently and when finished gave me suggestions about more durable products I could buy the next time. I was very grateful for all -- and then, I suddenly needed them again, asap, as I had raw sewage backing up in the toilet and bathtub of my downstairs bathroom. He came out immediately, diagnosed the situation and suggested a repair. He also offered to implement the repair a few days later at the beginning of the next week. His quote for the repair was beyond reasonable, very low. I asked an engineer neighbor and another plumber for their views of Mo's proposal and they both said that it looked good and made sense and was a great price. Plus, I have collected many estimates for this job and diagnoses for this problem recently and Mo's proposal was in line with the view of other plumbers but he gave a more lucid explanation. Unfortunately I cannot report on the work he did because my upstairs neighbor called and threatened him, saying she would call the police if he went ahead with the job. She did not view it as an emergency and I did not want to endanger him in any way. He had already deposited a debris bin and cleared his schedule for the week to do my job, but he didn't charge me for his lost client time or retrieval of the bin. I hope to use him when I manage to get this job done as I have a lot of faith in him and respect -- and big gratitude that he didn't charge me for delivering and retrieving the bin and his cancelled jobs on my behalf. Thanks for everything Mo! Hope to see you again soon read more

I woke up this morning to a completely overflowed toilet and 2 inches of standing water in my bathroom and the toilet gave no indication of letting up. These guys came out within an hour and really saved my ass I'm going to save this phone number and thank you so much read more

The service was excellent for a very reasonable price. The team was also friendly and I highly recommend going to them for any plumbing needs. read more

Mo fixed my water heater pilot light years ago and gave me good advice. That water heater finally died of old age and when I searched for his number to install a new water heater I discovered he has his own company now. Good for you, Mo! He asked me to text a photo of the unit along with the model number ID on the side and area around it so he good give me a realistic quote on how much it would cost. His price was a couple hundred dollars less than the other two companies that I had priced checked that day. The following morning Mo stayed tight with me via text saying that he was going to arrive about 20 minutes early. Awesome~ He and his crew; E.D. and Juan were courteous and did a great job. He remains at the top of my list of good dependable plumbers to call. read more

Mo, as always, provided fast and efficient service. One Source is reasonably priced and is my #1 choice in the Bay area for plumbing issues. Thanks Mo! read more

Frank is very knowledgeable and knows his job. Got the job done without any mess. Thank you for a great job.

I called One Source the day after my bathroom sink clogged up and my hours of plunging and applying liquid plumber did nothing to resolve the problem. Mo answered the telephone and was very courteous and professional. We agreed he would come the following day within a two-hour window of time. Mo arrived within that window. He was as courteous and professional in person as he was on the phone. He quickly diagnosed the problem and had it fixed in little time. I was pleasantly surprised when, without my prompting, he cleaned up the area he worked in with tile cleaner and paper towels. Mo was polite, respectful, professional and knowledgeable. I highly recommend him and One Source. read more

The day before I had guests set to arrive, I discovered that my bathroom sink was barely draining. Mo warned me that pedestal sinks could be difficult but he came the next morning and he and his assistant took apart the sink and cleared every component, even snaking the pipe to the street. Once the clog was located and removed, they cleaned my bathroom thoroughly and explained the situation clearly. Mo is very professional, honest, and dependable, and is clearly an expert in his trade -- exactly what you want in your neighborhood plumber. I will keep his number on speed dial. read more

Mo and his team do great work. He came to do the estimate and were clear about what needed to be done and the options we had. We repiped our victorian home and it was done perfectly. We approved the proposals and scheduled the work. He arrived and noted, as proposed, that the work would take two days. The first day he checked out the space and got to work. We had an idea of how things would go but he was able to, after checking out the situation of the old galvanized piper meeting newer copper pipes he was able to work a repipe that was nicer than we had expected. This was a pleasant surprise. At the end of the work day he checked in with me and let me know what they had completed, showed me the work and gave me the schedule for the next day. He was clear to communicate when the water would be off and how the process would work. The second day we had a new tankless water heater installed and my goodness is that thing powerful. Hot water for days! He finished connecting the faucets, toilets, tubs, etc and tested everything. We now have water pressure that I haven't had since buying the property. I've been in the home for 20 years and never had better pressure/hotter water. We decided to do exposed repipes as the alternative involved much more coordination and steps in the process. They look great! He was sure to keep the visual lines clean and almost artsy. Job well done! read more

Excellent customer service! Always on time and provides great work quality. Highly recommend Mo!

Mo provided very competent service. He followed through every step of the way. He explained the process and effectively problem solved when unexpected and difficult issues arose. He is trustworthy and easy to work with. I felt confident that the work completed has, resolved our major plumbing issues. He's a good guy. read more

Mo was super responsive and helpful with a plumbing situation of very inconvenient timing (the night before Thanksgiving). He asked me to text him a picture and walked me through a stop gap measure to stave off the geyser of sorts until he could come out to do a repair. He contacted me to schedule a repair and would have even come earlier than scheduled if I could have been home earlier. He repaired our utility sink very quickly and was a pleasure to deal with. He's responsive to phone calls and texts and was the only plumber I called that night who actually helped me (I called about 5 so-called 24-hour plumbers and none were available except Mo). Thank you, Mo! read more

Mo is the best. He's super responsive, does great work and is extremely professional. He's always my first call and if he's unavailable he will recommend someone else. I had a recent crisis and he was at my house within 30 minutes. Can't more strongly recommend One Source! read more

Mo has come out to our place multiple times for big and small jobs. He always answers the phone right away, comes out promptly and gets it done. He is professional, competent, honest, and reasonably priced. Go with Mo! read more

Responsive when I called around 1:30am on Friday night. I spoke w a plumber not an answering service. Mo was at my office at 8:30am and he texted 20min ahead of time to communicate that he was on his way (as he said he would). He solved my problem quickly (within minutes). He was friendly & personable. I will call him again if I ever face a similar issue. Thank you, Mo. read more

Very knowledgable and friendly! I had a situation where my sink facet broke and the water wouldn't stop. I called this number and the guy who picked up was super nice and friendly. He helped to debug the issue and think of a fast fix over the phone to get the water to stop flowing. He was extremely knowledgable about kitchen sink plumbing. read more

I have a pretty urgent need and although the plumber could not make it out to my location immediately, he offered to help me fix it myself by giving me instructions over the phone. I'll DEFINITELY be calling again! ***UPDATE*** Mo was just here and fixed my leak in under 45 seconds. We're having him back tomorrow for some more maintenance. read more

We had a dishwasher emergency at 11pm - where water started gushing out of our dishwasher into our kitchen. One source plumbing saved the day!! First Mo walked me through how to turn off the water and stop the flooding so we could go to bed. The next morning - he walked me through how to locate where the issue was - all over text because he wasn't available to come to the house till later in the day. He couldn't have been more helpful or friendly . I'll be going back for any plumbing needs in the future. Thank you Mo!! read more
