Called OSJ electric to help replace a defunct outlet under my kitchen sink as well as add a new outlet in the garage where they was not one.
They were extremely responsive and was able to book them for the next day.
Ossamu was incredibly friendly and punctual. He completed the job in a timely manner and everything works great.
10/10 would highly recommend for anyone in need of an electrician.Helpful 0Thanks 0Love this 0Oh no 0 - Neda H.Walnut Creek, CA18Mar 19, 2024
I cannot speak highly enough about the exceptional service provided by Ossamu and his team. From the moment I reached out to schedule an assessment to the completion of the job, every interaction was professional, courteous and efficient.
Despite having to reschedule our assessment multiple times due to my own shifting schedule, Ossamu remained incredibly accommodating and understanding. And when the time finally came, he was prompt and friendly.
We were on a tight timeline to get the electrical work done before hosting a big party the following week, and Ossamu went above and beyond to accommodate our schedule. They worked diligently, ensuring that everything was completed on time and to the highest standard.
Not only did they do an impeccable job initially, but they also returned to do a few touch-ups and ensure everything was perfect and to our liking. I really appreciate their attention to detail.
I would not hesitate to recommend Ossamu and his team. Without a doubt, I will be reaching out to them for any future electrical issues. Thank you, Ossamu, for your outstanding service!Helpful 0Thanks 0Love this 0Oh no 0 - Sameer S.Lafayette, CA418Aug 22, 2024
Ossamu was incredibly responsive and helpful when we really needed it. Living in an older house we have worked with many electricians over the years and he is definitely one of the best.

Work on the backup battery system.
It was installed few years back and we wanted to make sure it was working.
Ossamu's service was exceptional. He is thorough with the work, very pleasant to work, also reasonable in his rates.
There were issues with connections. He was able to troubleshoot and fix the problem.
He patiently explained the functioning of the system and I was able to video it for future reference.
Very thankful to have found Ossamu and will be using him for our future projects.Helpful 0Thanks 0Love this 0Oh no 0 - Henry L.Fremont, CA62219Apr 25, 2024
I had asked Ossamu to give me estimate for changing two different circuit breakers boxes for two of my rentals. Both houses are over 55 years old. Ossamu did some electrical troubleshooting for me in one of the two places. Ossamu showed up on time and he finished both projects ahead of schedule. His work attitude is great, he got lots of tools just pulling an old circuit breaker and patch up some small drywalls. Many people think it's easy but it's not that simple to pull it from an old house w tenants living inside. He got both projects done on time and he came back the next day to re-labeled all circuit breakers. I highly recommend him for any electrical troubleshooting or replacement. His price will not be the cheapest, I think it's a very fair price from an honest and hardworking small business owner. I highly recommend him to my neighbors.

Ossamu is a magician. He took a technically difficult EV charger install project at our home (part of a larger garage remodel) and made it seem easy. He had to trench our front yard to hook up the electrical on the other side of the house. We had some difficulties with the installed Tesla Universal charger and he was always available to help troubleshoot. We then swapped that out with a Chargepoint and the first one had a WiFi problem so he came back to install one that works very well. Again, he was always able to help me troubleshoot via text or in person.
Net net - there are always issues that come up in home projects and Ossamu's resilience, patience, professionalism and affable nature constantly took the stress away.
This guy is a total pro. You will want to work with him again.Helpful 0Thanks 0Love this 0Oh no 0 - Colleen C.East Bay, CA019317Oct 28, 2023
Thank you Ossamu! We had a issue with our electricity in the kitchen, causing our stove not to work. We originally thought that our stove was broken and spent an unfortunate sum of $$ for a Samsung technician to tell us it was not the stove, it was our outlet. We reached out to several electricians on Yelp but Ossamu was the only one that followed through despite a busy schedule. He came after 5p on his way home from another job and thank goodness because what he found was that the previous house owners had installed wires that were incompatible with our stove and the wires in the wall had in fact melted and smelled of smoke!! He was able to make some repairs that evening so that our stove was operable and made some suggestions for a longterm fix.
Ossamu was courteous, professional, friendly, and we are so thankful to have met him. I will be holding on to his number for future electrical needs! Thank you again.Helpful 0Thanks 0Love this 0Oh no 0 - Tim B.The Haight, San Francisco, CA24313Apr 22, 2024
Ossamu was quick to respond, great with communication, and thorough with his work. He explained to me what was happening and was willing to go into great detail (so I could nerd out and learn).

Six Stars ****** :O) Osammu did a first class job installing our Tesla car wall charger and was incredibly nice throughout the process. We had a long run from our main breaker panel on the side of the house up to the house attic, across to the garage attic, across the garage, and then down the garage wall, and the install was perfect with no exposed conduit and the charger in the perfect spot. His communication was prompt and clear, and he made sure to fit us in to his schedule right when we told him we were getting the car which was only a few days after we contacted him through Yelp. His price was competitive as well from what I read online and the other couple bids I received. I highly recommend Osammu and OSJ!
