Matt was very prompt, very quick, and very efficient. Excellent customer service!!!

Sat 8/1 5:52pm - pipe underneath kitchen sink busts and water spewing full blast in my kitchen and can't stop Sat 8/1 6:01 pm - call Mostafa in a panic and he said would be there in an hour. Sat 8/1 6:45pm - Mo arrives and immediately shuts off water. Then calls Water Damage Recovery to get to my apt ASAP to do water damage. Sun 8/2 - Mo comes over and completes repair of sink. Busted supply valve. Watching water spew out full-blast in my apt and not being able to stop it is sicking and surreal. But dealing w/ Mo who understood my emergency and kept me notified as to when he would arrived made it easier for me to deal with. And getting a plumber to arrive within an hour on a Sat evening in an emergency, makes me believe that Mo is not just a plumber, but a guardian angel plumber! My landlord was so impressed w/ Mo's work that she is now going to use him as her plumber vendor. Bottom line: Any plumber can come out in three days to repair a random non-emergency issue. It takes a hella awesome plumber to arrive within 45 MINUTES on a Sat evening and save your apt and all your valuables from getting destroyed by flooding. 24/7 Mo is there for you. No shit. read more

It's with great satisfaction that I write to give Mo and One Source Plumbing my highest reference. I recently called for an estimate on a leaking sink. I had previously benefited from Mo's service in the installation of a water heater that had been damaged by another Plumber and was luckily replaced by warranty. Mo came out this time and diagnosed that the faucet that had been previously replaced by that same Plumber was damaged and leaking. He gave me an estimate for his labor to install a new Delta faucet. Mo overcame some adversity with the terrain of the sink and the parts supplied by Delta and installed the new faucet within his estimate. The new faucet works like a dream! I would envision using no other Plumber and heartily recommend Mo and One Source Plumbing to anyone looking for quality work at a reasonable price. Mo has earned his place as my Plumber relationship! read more

Mostafa is a competent and reasonable guy. He worked through a really tough sewer mainline problem without complaint. He was responsive and finished the job professionally. I'm definitely going to call him again. read more

No one ever likes to have plumbing problems, but if you do you MUST call one source plumbing!! It was fast and easy to coordinate a time and Mo was very knowledgeable and honest. I don't know much about "home improvement" type situations but he took the time to explain everything before and after the visit. 5 star service, 5 star work, 5 star experience! read more

Super impressed with Mo and One Source. He squeezed us into his schedule on short notice, was polite and professional, and explained our options in easy-to-understand language. If only all tradespeople were as courteous and helpful as him! read more

Mo went above and beyond to help me! I had an emergency leak in the evening and called several plumbers who were not available to help. But when I called One Source that evening, Mo picked up the phone right away and stayed on the phone with me for an hour to help troubleshoot the problem. He walked me through a temporary solution for the evening and then came over with his crew the next morning to address the problem. Mo and his team were very thorough and reasonable--I highly recommend them! read more

I've used One Source for several plumbing problems at our home over the past year and a half and they are great. Quick to respond, on time, excellent service, thorough in identifying the problem, clear in explaining what needs to be done and the costs, and then they do the work to completion as expected. The One Source guys are true professionals. I would highly recommend them to you and to any friends who need a great plumber. read more

Our plumber bailed out on our bathroom/kitchen remodel last minute. We called one source and they agreed to take it on. We had to sell the house so we had dead lines to meet. They had the drain, water and gas done and signed off by city inspector in 4 days. And after floors, walls and tile was up they had the finish trim in 1 day. We buy and sell houses often and work with a lot of plumbers. It's almost normal for them never to meet their dead line. But one source truly is knowledgeable on the time frame of they can get stuff done. read more

Same story as the others. They answered when others did not. Very easy to communicate with via texting and phone. Gave a window between 10 and 12, but came promptly. Mo was honest and quick; he didn't try to pressure me into anything and did a thorough job. The inspection was free and he evaluated a lot of things, and then told me what he was going to do and was very direct about the price. He gave me a very fair price; and even helped me with some minor toilet issues without nickel and diming me. The main problem we had was a clogged main line, and he sent a power snake down there to unclog in, then he set up a T.V./camera to show us what was going on down there, so we can see for our selves: a plant root problem going through the pipes. They did an excellent job of cleaning it all out, in less than an hour. All of the plumbing works perfectly now. Thank you. read more

Mo is my go to Plumber. He is timely, friendly, and conscientious. I have used him twice and he always explains the issue and give you advice on how to remedy the problem in the future. He will work on the problem until it is solved. Pricing is beyond fair, not the usual Plumber high fees. read more

Wow these guys are good! Friendly, quick and able to get the job done with short notice! I highly recommend One Source Plumbing for any job big or small. read more

These guys not only know there trade well, but they are responsive, efficient, and there is no sticker shock on pricing. We have had a number of issues in our older San Francisco condo complex, and troubleshooting and coming up with ideas and alternatives is important. Mo is able to rationally approach the problem, suggest solutions and walk the client through the options. There is no rushing the client to a quick decision as other contractors sometimes do. Thanks - please keep it up! read more

Amazing work! I had 4 plumbers over trying to fix my water heater problem and none of them could deliver until I found Mustafa. He made 3 trips ( ordering parts)and patiently solved my water heater problem with a very reasonable price. Definitely recommend! read more

Mo is the only plumber I use in San Francisco. Mo has unclogged my kitchen sink, my bathroom sink, and fixed my garbage disposal problems while being extremely honest - not lieing or up charging me like other plumbers I've used in the past. He frequently comes same day or next day and remembers my past issues, educating me on how to prevent them going forward. Highly recommend him to anyone who needs a plumber! read more

It rare to find anyone who is so competent, honest, and fair. I had a difficult repair on old pipes, and a faucet that needed a creative fix. Mo was on it the next day. He did a beautiful job, quickly, and made a creative fix that is solid. Even better, his prices are fair. I cannot recommend him more highly. If you need the best, for a fair price, call these guys. read more

Great service. Mo was fast to respond, did a great job of exchanging the water heater and had a competitive price. I will be using his services from now on. I would recommend him to anyone. You can trust this guy. read more

These guys were the best. I somehow dropped my phone behind my toilet with no possible way to get to it. The folks at One Source took my call and within thirty minutes were at my doorstep. Not only did they help retrieve my phone, but they fixed some other issues with the toilet that I didn't even know about! Amazing. Absolutely dumbfounded by their skill and professionalism. Will be sure to use them again (hopefully not in a situation that involves a lost phone). read more

Words can't explain how thankful I am for One Source Plumbing and Rooter. These guys are just flat out amazing. I needed work done at my house and business and Mostafa came out the same day and started on all the work that needed to be done. I would definetely reccomend these guys to everyone who needs professional plumbing done on time, efficiently, and for a very reasonable price. read more

Plumbing issues are no fun but I had a GREAT experience with Mo- very knowledgeable (even about the old building that I reside in), super helpful (suggested immediate solutions over the phone), efficient and timely. I had an urgent plumbing issue and he made time off hours and on a holiday weekend. He was great with communication, showed up on time, and finished quickly and was so pleasant to deal with. Pricing was very reasonable and the whole experience was easy. I would highly recommend him for any plumbing issues, and I am really glad I found him through his other fantastic reviews. read more

We highly recommend One Source! Fast, efficient and terrific customer service. The City of SF notified us that our water pipes from our house to the street needed replacing before they could continue work on city water pipes in the street. We called Mo, and the next business day he was filing for the city permit. The next day he replaced our pipes, and poured the new cement the third and final day. Also, he communicated to us in advance when he had to make slight schedule change; not many contractors provide such important details. Thank you, Mo! read more

Mo and his crew replaced the main sewer pipe in our home. I couldn't be more pleased with the quality and level of service One Source provides. Prompt, courteous and very easy to work with. Our experience resulted in a very satisfactory outcome. read more

I noticed signs of leaking around the base of my toilet, so called One Source to see if they could help. Mostafa (Mo) texted in advance to give a more accurate arrival time estimate, showed up within the agreed time window, immediately diagnosed the problem (a cracking wax ring), got the toilet up and a replacement in, and fixed a fiddly flush while he was at it. Aside from being polite and personable, he was careful to move our things out of the way before starting work so he wouldn't get anything dirty, and cleaned up before leaving. Payment was easy with Square Register. Quick, painless, and affordable! Thanks, Mo! read more

After a 6 month hassle between us and our previous plumber, our sewage issue never got permanently fixed. One source came out and found out that there was a bad sewer valve in the bedroom. Once replaced never had issue again. Finally can get out of town with out having my tenants call about plumbing problems. One source is our go to read more

Mo is AMAZING. We had a plumbing emergency and I frantically called every 24/7 plumber in our area. He was the only one to answer my 12:30am call and although he wasn't available to come right away, I got a really good vibe from him. So when our emergency went from code red to manageable, we decided to wait until the next day when Mo was available. And I'm SO glad we did - he was courteous, professional, knowledgeable, and just a nice guy. He'll definitely be our go-to plumber from here on out! read more

Mo came to our apartment to fix our sink. He did an excellent job, the service was fast and clean, and I am thankful everything has been repaired. I highly recommend this company. read more

These guys are AWESOME. We had a nasty situation in our sink. I called, was called back 10 minutes later, and then they were at our home 15 minutes after that. They cleared out all the nasty buildup and diagnosed the problem (an electrical issue with our disposal) and didn't even ask for any payment! It kind of blows my mind how nice these guys are. Feeling very grateful. read more

Mustafa texted me back very quickly after I pinged him and 20 minutes later he was at my apartment on a Sunday night. We had a unique situation with some old pipes and dual clogs in the bathroom sink and bathtub. It was confusing and difficult, but he persisted. He even modified his equipment by grinding off the head of his plumbing snake so that the a thinner part of the snake would fit through our old pipes. He only charged us for one of the clogs and didn't charge us the typical emergency charge that every other plumber quoted me. Last, but not least, he cleaned up the huge mess afterwards and gave us a warranty on the work. USE THIS GUY! He saved us. read more

These will be the go to guys if I ever need plumbing work done in the future. Our sewage system decided to take a dump, literally, and we called Mo and he came out and gave us a couple estimates the same day. We called a couple other places but they charged more and with the great reviews on Yelp we decided to go with One Source Plumbing. Mo, the owner, does all the work with a couple other helpers so you can trust he'll do the job right! Everything he does is up to city code and standards and he works very efficiently. Was able to tear out our sewage pipes and put in new piping and had our plumbing back up and running the next day. Highly recommend One Source if you have anything small to large jobs. read more

Outstanding & thoroughly competent. Did a very difficult job quickly and well. I highly & unreservedly recommend. He'll do it right.

We couldn't open up our business because of a remodel that was incomplete by a previous contractor, who just left us hanging. No other company wanted to deal with a unfinished job. (One Source) thankfully agreed to take on the job and were able to deal with all the different inspections and inspectors smoothly. And with in 3 weeks our restaurant was finally opened to public. Will definitely use them in future. Very reliable !! read more

Came out on time. Evaluated the leak and that it was not coming from my house. Recommended a company to further diagnose the leak coming from a neighbor. Very professional and helpful throughout. In addition, he wouldn't take any money - said the evaluation was free. A+ customer service in my book. read more

When Liquid Plumber didn't do the trick on my clogged kitchen sink last night, I called these guys. (Unlike the 8 "open late" places I called first, here an actual person - Mo - answered the phone.) He got the details from me and told me what he suspected was going on. He came over within the hour, was spot on with his analysis, and fixed the problem in less than an hour. And he was a really nice and polite guy to boot. I highly recommend this company - they are professional, fast and open late! And the price was very fair for the speed and service I received! read more

I am so grateful that Mo picked up the phone this morning and was available to help with my weekend plumbing emergency, even when no other plumber (including those that say 24 hour service) would return my call! Not only did he fix the pipe that burst under our kitchen sink, but he also fixed a less urgent issue with our tub, and did both at a reasonable cost. I would highly recommend him to anyone in need of a plumber and am so happy to have my kitchen sink up and running again! read more

Used them four times and each time they are super prompt, cordial, professional, affordable - could not be more ideal! Best guys ever for all sink/plumbing needs read more

One Source Plumbing And Rooter is just amazing. Very professional, efficient and honest. i would describe these guys. The water pipe in my kitchen suddenly exploded and i was in shock. i googled for plumbing companies and choose One source plumbing and rooter randomly without having any clue what kind quality of service they provide but once i called them they were available and came so fast to fix the pipe. They saved my life from drowning into the big ocean and cleaned all mess. so satisfied and i will recommend their service for everyone. read more

Great service! Super quick! No more problems. Highly recommend. I was having problems with my sink and they told me exactly what was wrong and how to prevent it in the future. Any other problems I will have at my house I will quickly give Them a call again. read more

After calling 4 different plumbing companies I was referred by a friend to one source and he came got the parts for me under warranty and charged me fair price for a labor ... And seemed very trustworthy, honest and very sincere in his work.. I would definitely recommend him for any who needs any sort of plumbing work done!!! read more

Great customer service! I had a huge issue in my house and one source plumbing came through when I really needed it! Honest and trustworthy service. I had a lot of bad experiences with plumbers in the past so I decided to try a new company. They explained what the root problem was and didnt charge an arm and a leg. read more

Mo answered the phone on a rainy day when I was experiencing a plumbing emergency and no other companies would answer the phone. He arrived and the situation (which was looking awful- water was so backed up it was about to enter the house) was resolved in under an hour. He should've been my first call- and from now on always will be. read more
