Our Plumbing Company was founded by my ancestor. Initially, we functioned on Lower Market near 3rd St. After the earthquake in 1906, the catastrophic fire obliterated our building, so our company relocated to Hyde St. I believe it was possibly his residence at that time. He unfortunately passed, and my father's father along with my grandmother assumed control of the business. In the 1920s, my uncle Henry Sand began his journey in plumbing after a short career in professional baseball with the Philly team and the Orioles. He was banned from baseball for reporting individuals associated with the issue at that time. In the 30s, we moved to 15th and Church, and we are still located there. In the 1950s, my parent and uncle entered the plumbing field until the 1990s, when they stepped back and enjoyed retirement bliss. My plumbing journey began in 1983, the same year left us at 83. He worked consistently up to the end. Having almost three decades of knowledge and aim to carry on this tradition.
I entered this world at Children's Hospital in the city in 1963. My family shifted from SF to a nearby town after I came into the world until I was 2 and then relocated to Millbrae, CA where I spent my childhood. I am blessed with an elder sister and a nephew who are now in college. My family remain in the place I was raised, and I bought a house in the same area where I make my home. I am married and have a teenage son who is now attending high school and twins, a boy and a girl who are in junior high. Family is everything.

Recommended Customer Reviews

I had problems with my water heater and thought it needed to be replaced. I called Joseph C. Sand and left a message. Bob Sand called me back soon, asked me what the problem was, and said he thought it probably just needed a repair. He repaired it for much less cost than I had anticipated - and far less cost than a new water heater. The next day he called to make sure it was working well, as he would be out of town for a few days, and wanted to make sure it was okay. I have never had better service, and highly recommend this company.

Joseph C Sand Company does sub-par work, and patently unprofessional.
The plummer managed to leave my sink worse off after working on it, and over-charged me for the privilege.
Joseph Sand never corrected the problem (he didn't even return my calls).
Save yourself a real headache: go elsewhere.

After reading all the positive reviews on yelp, I thought I'd give them a try.
I left a vm midday: I got a call back by the end of the day, confirming my requested time:2 days later for a drippy kitchen sink.
Confirmed date & time comes: nothing. I had already taken time off to have PGE come out for another issue, so I wasn't too stressed. But when I didn't get a return call or anything within 4 hours of our scheduled service call, I was bummed.
I left a message for him at 45 mins late.
Then I left another message for him 5 hours later, requesting a rescheduled appointment.
nothing.
Now, days later, no courtesy: Sorry I messed up, let's reschedule call.
Bizarre.

We found Bob Sand when we moved into the neighborhood ...years ago. Every time we've called we've had prompt, reliable, high quality and reasonably priced service. It's a few years since we needed plumbing help, but when we do Joseph C Sand ( and Bob) will be at the top of our list.

I searched Yelp for a plumber, found Mr. Sand and contacted him to install an earthquake gas shut-off valve. He responded promptly to my call, was polite, answered all my questions thoroughly, quoted a fair price and installed the valve as promised on the agreed-upon day.
When I had a follow-up question a few months later -- unrelated to his work -- he called me back and told me what I needed to know.
Can't get much better than that, I don't think! I'll call him first if I need additional plumbing work.

I lived in a flat for 7 years with a toilet that clogged a couple of times a month. I got a new toilet, same problem. After I moved out, some friends moved in and the toilet clogged at least once a week. We all became expert plungers. We had numerous plumbers come out to snake the toilet over the years.
Finally, I called Bob and he was the only person in 9 years that fixed the toilet. I've been back in the flat for 3 months and not a single clogged toilet! He's done other jobs for me like installing a dishwasher, fixing leaky sinks, etc, but I am most impressed that it took him 20 minutes to fix a problem that that no one else bothered to figure out.
He's honest, efficient and I highly recommend his work.

I found Joseph C Sand Company because of the high reviews and used his services a few months ago. We called him to clear a very slow shower drain that became completely blocked once I tried to clear it myself.
I made an appointment for the next day, since I didn't consider this an emergency and we had another shower to use in the meantime. Bob was courteous and punctual and had the drain cleared in short order.
Unfortunately, two days later, the shower drain blocked again. I called Bob to ask him to return to re-clear the drain. He was there punctually again and cleared my drain again (at no additional charge) and it has stayed clear since.
I found Bob to be extremely competent and his rate seemed reasonable.

For decades the property owner in my rental has been using Bob for all the plumbing needs in our building. He has always been prompt and has done a good job in a short period of time. If he needs additional parts, he gets them and returns quickly. He is polite and clear in his communication. I often know what the bill was and it has been very reasonable. He does not leave a terrible mess either, which is nice.
The property owner usually tries to pass the plumbing costs on to me, saying it was my fault. Due to this, I make a point of asking Bob if I have done anything to cause the problem, and except for one time when there was a hair issue due to no catch in the drain, our use has had no impact on the problems. I have told him why I ask this question and since I am not the one paying him, it would not have surprised me if he hedged his answer. He never does though. This causes me to believe that in addition to doing good work at good prices, he values his own word over the dollar, making him highly credible.

We are a property management company and ONLY use Bob Sand for our plumbing needs. We have NEVER been disappointed. I believe our company used them when his dad was there so it's been a LOOOOOONG time. He is fair, honest, reliable and my favorite - ON TIME!

Bob has been our buildings plumber for years now and I can't think of using anyone else. This guy is the real deal. I say no more.
