I am the sole proprietor of AceStar Plumbing. Licensed and bonded #1000763. Currently active.
I started my plumbing career at the start of 1999 with a large plumbing corporation located in the East Bay. I dedicated a total of five years working in Alameda and Contra Costa County. As my plumbing expertise grew, I was offered a position with a local family-owned plumbing firm in the Tri-Valley area. We aimed to grow a community plumbing service specializing in offering comprehensive plumbing solutions for both commercial and residential clients. I gained significant experience during my time there. Within 12 years, I learned a great deal from a small company in both office roles and fieldwork, inspiring me to obtain my own contractor's license back in 2015. I am now managing my own plumbing company, answering phones and working on projects in the community.

Recommended Customer Reviews

I am a first time customer. We had our water heater replaced by Johnny and his crew today on super short notice. I called around 10am and they were here working on taking out the old water heater by 1:30pm. The whole crew was very friendly and very efficient! They brought in the exact size water heater we needed and no significant modifications were needed to make it work in our HVAC/water heater closet. I am impressed by how organized they were and how swiftly they replaced the old failing water heater with a new one. The finished install also looks cleaner than the previous setup. These guys are professionals and I do not hesitate to recommend them to anyone who needs a water heater replaced. We will probably call them first if we need other plumbing related work in our house. Thank you Johnny and crew!

Courteous and competent! And reasonable too! Will definitely call Johny back! Thanks!!

I have used AceStar Plumbing twice with great results. Johnny comes on time
and has very reasonable rates along with his excellent service. I recommend him for your plumbing needs

Johnny is very professional, responsive and covid-cautious ( masks booties etc).
He has done multiple job in my house: install fridge water line, replace galvanized piping from the house to the street, create exhaust/duct for the laundry.
He is efficient friendly and very good overall. He is now my go-to plumber for any questions and issues.

Showed up with a mask and shoe covers. Very efficient and professional work. Price was very reasonable. I would heartily recommend this company for your plumbing needs.

If you need a local plumber in the El Sobrante area, you can't do better. Fast response without the hassle of the bigger companies. We had an embarrassingly simple problem, and AceStar didn't charge an annoying service fee.

Bypassed the LEAKING water pipe from under the house concrete slab by rerouting the water tubing through the attic to the main WATER MANIFOLD and replaced the old WATER TANK, all in one single day. They did a clean and professional job. Above any expectations. I highly recommend them especially for people living in the Sherwood Forrest area because they know the plan of the houses. Their estimates are comparatively very reasonable.

Our Oakland home has two original 1930 era toilets that developed leaks coming from the pipe that connects the toilet bowl to the wall-mounted tank.
As it turns out, it's hard to find a plumber who is both qualified and willing to work on vintage toilets. Most plumbers want to scrap the old toilet and install a new toilet. In our case that would require ripping up our original bathroom tile floors to install a new flange and sacrificing the authenticity that is part of our heritage home.
Johnny at AceStar Plumbing came to our rescue. He was actually referred by another plumber who didn't feel qualified to do the work. Johnny's only requirement was that I purchase the needed parts (flush valve, ell and spud) and have them ready to install. He carefully removed the wall tanks, replaced the parts, reassembled the toilets, secured the tanks to the tile walls using new anchors and thoroughly tested everything.
In addition to fixing both toilets he repacked the leaking hot and cold water valve stems in the shower.
I can confidently say this about Johnny -- he responds quickly to calls and texts, he is on-time, he is thorough, he is honest, and he is fairly priced. I would highly recommend him to others and would use him again for any plumbing issue that may arise in the future.

Got this referral from home advisor., I had a leak in my garage ceiling from an upstairs bathroom., I thought the worst tearing up sheet rock and so on. When he checked it out it was an issue with the faucet. RELIEF! Very professional glad I found him!

I highly recommend AceStar, particularly Johnny. I've had him replace water heaters at our own home and our rental house. He does what he says, when he says! He only installs top-of-the-line brand, which has resolved all issues I've had from using brands from Home Depot.
Everything is now up to code - no hidden or added costs. His quote is honest and doesn't vary - even if it requires extra work.
Please call Johnny and at least get a quote from him. The other plumbers I've used, sent by Fidelity Home Warranty, did not do the work properly and have cost more money in the long run.
For some reason it seems more difficult to find honest, knowledgeable contractors than it should be. Johnny was recommended by a friend and I'm glad I took her advice.
