In 1984, Jorge first encountered plumbing when his village in El Potrero Jimenez Del Tuel Zacatecas, Mexico, received a government grant to acquire materials for providing water to over 700 homes in the area.
Mr. Sanchez immigrated to the U.S. and established himself in Marin County, starting his plumbing career with Rich Port Mechanical Plumbing Inc. in Richmond, California, in 1995. Eager to broaden his expertise, Jorge took on more complex plumbing systems, including industrial and commercial projects such as buildings, laboratories, and hospitals. Between 2000 and 2012, Jorge furthered his knowledge at Ongaro & Sons Inc., obtaining certifications such as Green Plumber Certifications and Green Plumbing Builder Certifications.

Recommended Customer Reviews

Jorge is a very knowledgeable and reliable plumber. He figured out my toilet problem within minutes when two other plumbers couldn't. He did a very good job with the repair. I would recommend him to anyone. Thank you!

I called 777 plumbing on short notice during a re-roof that required a couple of vents to be relocated. Jorge was very responsive, came out the same day to quote, and moved his schedule to keep my other contractors on track.
He was very open about what options I had - and gave me choices to fit the budget. highly recommended.

Quick response time; good communication skills; knowledgeable, efficient and experienced plumber. Excellent work and good cleanup. All plumbers are expensive; this company is by far the best I've used. (Stopped leak and installed new valve in Master shower.)

Jorge Sanchez, the owner of 777 Plumbing, is absolutely the best! A car ran off my road Christmas night around 1:30am and broke a water pipe, and to keep from washing out the driveway, the Fire Dept. had to turn off my water. I called Jorge (based on other Yelp reviews), explained the problem, and he was at my door less than an hour later. He was able to cap off the broken pipe, and put a cone and hazard tape around it, and get my water turned back on in a couple of hours. As a bonus, he's very nice, and his prices are reasonable. Highly recommended!

777 Plumbing is great, highly recommended! Jorge was available on short notice when other places were not and easily fixed the water valve behind our refrigerator that was leaking. Thank you, Jorge!

Jorge is the best. I am a real estate agent and need help all the time for my clients. i have used hundreds of plumbers over the years. Jorge is honest, hard working, responsible and appreciate everything he has done for my clients and me personally. I recommend him without hesitation.

Jorge is one of the most responsible, honest, and reliable plumbers I have ever used. In addition his costs are very reasonable. I called Jorge to help with a broken water heater. He immediately responded, knew what parts were needed, and continued to respond until the job was done 100%. He is a good man and I will always use him for any future work. It's difficult sometime to find people who really care about you and your family. Jorge is one of the rare ones. Thanks so much.

I have had 777 Plumbing (Jorge) work on two projects in the last several months. One was replacing a piece of old cast iron pipe under the house and more recently a dripping bathroom faucet plus some advice on the hot water heater. Jorge always seeks to find the best solution and to explain why. His costs are so reasonable considering the level of work and expertise he provides. He values his work and is honest and dependable. I highly recommend him!

It is nice to trust someone on the price and work they do.
Work with Jorge on multiple project and he was very dependable and had great recommendation. On top of that his price was very reasonable.
I will do business with Jorge again ANY TIME!!!!

We lived in our Tiburon home for 28 years. For 20 or so, we struggled to find a consistently good plumber. When Ongaro Bros sent us Jorge Sanchez we were delighted. On the several occasions he came out, he did a wonderful job.
When Jorge formed his own company, 777 Inc, we continued to have him do our work. He did an amazing installation of a hot water heater and a furnace bringing our tract home up to modern standards. The Tiburon Building Inspector came out for the sign off and noted, ""Really nice job.""
Jorge also took on the job of re-routing our kitchen waste line (that had run through the slab and frequently backed up) to a dedicated line that all of a sudden made running the waste disposal a dream. The Sanitary Inspectors came out to sign off and were impressed by the job and ""double cleanouts"" that he had installed outside the house.
In addition, on several smaller jobs, Jorge always sought to find the best solution, but one that didn't break the bank. He's a master at finding the ""little"" things that mess up plumbing. He will find the small spring in some fixture and replace it rather than recommending getting a new appliance.
He was always punctual, clean, professional, and pleasant. I give him my highest recommendation. J. Rogers
