Electrical work can be stressful especially when involving opening up walls, but OSJ was so professional that I felt good the whole time. I am a picky home owner (asked for clean install, specific wires, etc.), and I would totally use Ossamu and his team again. I had a level 2 EV charger installed with remote metering. read more

Ossamu and his team installed a Tesla universal charger outside for us. He and his crew were phenomenal. Professional, friendly, and prompt. I'll absolutely hire them again when the need arises. 10/10. read more

Buzzing light fixtures are now quiet. I texted a request for an estimate on OSJ website and got a quick response. Texted back some information about the problem and got an estimate and that's what was finally billed. No up-selling! An appointment was set for the next day and problem solved. The crew was pleasant and efficient. Left the work area spotless. I will use OSJ for future electrical work. Highly recommended. read more

Ossamu was a consummate professional. He quickly scheduled an appointment to provide me with a free estimate. He took his time and was incredibly thoughtful and detailed with his explanations. He considered multiple options and provided me with the information I needed to proceed. Ultimately we had him (and his team) out twice to do 2 separate electrical jobs. I recommend him without reservation. read more

This had to be the most efficient, honest and easy transaction I have experienced. My main electric panel busted and PG&E had to come out and inspect it. They told me I had to change the entire panel. I called about 5 companies. OSJ Electric price was the most reasonable and knew exactly what to do with just a few photos ( no bs and straight to the point). Ossamu and his team are very attentive, clean, organized and knowledgeable. They don't do shortcuts and very thorough. Excellent work. read more

Professional, on time service with an experienced electrician. Andres was kind and courteous with my 91 year old Mother. No up selling and the estimate quote d was what we paid. You can not beat OSJ Thank You. read more

Fair price, fast service, no requests for an unnecessary site visit, no bs. So: 5 stars.

Highly recommend Ossamu and his crew. We wanted to install an EV charger in our home and Ossamu was very easy to work with. Work was done on time and the cost was reasonable. They did not even ask to be paid until the inspection was complete. Really classy team that takes pride in their work . read more

I needed a new fuse panel with all new breakers and a dedicated line to my work bench in our garage. I got 4 estimates and Ossamu was the most reasonable and he was the most personable. I really appreciated his kindness and immense knowledge. He and his crew did a great job, and I would absolutely use them in the future! Highly recommended. read more

We recently had our house's electrical system completely redone by OSJ Electric. Ossamu and his entire crew were professional, courteous, and highly efficient. They managed any additional requests we had throughout the process with great skill. Just last week, we needed to upgrade two motion sensor flood lights, and once again, Ossamu and his team were prompt and effective, making the entire process seamless. Their pricing is fair, and OSJ Electric has promptly addressed the very few issues that arose. We highly recommend OSJ Electric. read more

OSJ Electric - Newly updated and electrical panel. - Electricians Near Me

This company was nothing short but amazing! The technician Ossamu in particular as he is the one who made my day! Our electricity had been out to half of our apartment for two days and he was very polite and quick with fitting me into his schedule the same day I called for service. He diagnosed the issue right away and we had power restored within 20 minutes. He was very friendly and explained the rates for service and what was fixed to me perfectly. I'd highly recommend them to anyone and to ask for Ossamu. He was friendly and made me feel like a priority. read more

I've worked on two projects with this company and am very pleased with their service and expertise. Most recently I had an unexplained outage in my kitchen plugs, and the response to my call for help was same day! After amazing detective work it's solved and so are several other minor issues. Thanks for the great work! read more

We had a wonderful experience with OSJ Electric! Ossamu and his crew did all the electrical work for our new hot tub as part of a larger backyard redesign. They were very easy to work with, extremely knowledgeable, had great communication throughout the project--overall excellent! I will be using OSJ Electric for any electrical needs in the future! read more

We had a huge project. My Insurance Company said it was our 1969 Aluminum wiring, or them. So, we had a choice to have it inspected, or replaced. After researching, we decided on replacement. There are 3 of us, plus a big dog, living 24/7 in a 2-story packed house. Plus very expensive wallpaper! Enter Ossamu and his team. For over a month we lived with Adam and Wilfredo. Not only were they very respectful of our personal space, they also took great care not to touch my wallpaper. It was sharing intimate space, and even though I was glad it was over, almost sad to see them go. My dog fell in love with Adam. I started calling them "our boys". They were responsive, great communication, and kept checking in with us. Adam was straight-forward about issues and timing. The final cost came in less than we anticipated! I had one electrician tell me it will be time and materials for about 4 months? Then he ghosted me...lol. The sheer terror! But Ossamu worked out a very reasonable contract. We still have projects for them, and I have no problem calling them my electricians. Me? I was a Commercial Property Manager of high rises for 35 years. Believe me, I am super aware of sketchy contractors. Ossamu is the real deal. read more

Ossamu is very knowledgeable and kind. He is very detailed oriented, Im very glad I went with him!

After soliciting bids from three contractors, we hired OSJ to upgrade our main panel from 100 to 200 amps, and replace our subpanel in the garage while they were at it. This will allow us to switch more appliances from gas to electric when we're ready. Ossamu was the easiest to work with, and was great at explaining options. He handled all the PG&E stuff easily, and I have no complaints whatsoever about the work he and his crew completed. I will not hesitate to work with OSJ again. read more

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. read more

Fantastic service - on time and excellent quality of service. OSJ electric installed 3 Tesla charges. They work great and we are very pleased with the electric output. read more

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. read more

See all

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. read more

Exceptional service. Competitive price. Great person. 100% recommend. Project: EV charger in carport. read more

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. read more

The whole team was great. They handled the electrical work for a shed to home office conversion and did a great job. They installed lights, outlets and a mini split, and even handled the logistics of getting the work permitted as well. Very happy with the results and the price was fair. I would recommend them to a friend and will probably hire OSJ again for my next project. read more

We had a great experience with OSJ Electric working on our garage remodeling project. Ossamu is a very detail oriented person, he thinks out all the possible options and comes up with the final solution. We got our electric panel upgraded, adding another panel and new wiring for adding more capacity, cleared all the walls of conduits and external wiring, running everything inside, installed recess lights, multiple new outlets, new focus lights on the outside moved solar panel to clear wall space and installed Tesla EV charger. The final outcome was much better than what we envisioned. Ossamu's work is beyond expectation. He is creative and comes up with solutions to any electrical need we have. Their pricing is reasonable for the quality of work and service. I will highly recommend OSJ for any electrical work and would definitely go with them for any future electrical projects. read more

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. read more

Ossamu was a pleasure to work with. He was able to come by on the same day, he completed our oven install and wiring within an hour, and he charged a very reasonable rate. I would recommend working with him, and if I have more electrical work in the future, I plan to work with him again. read more

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! read more

Did a panel upgrade (from 200 to 400 amps) and went above and beyond given some challenges dealing with PG&E. Also did 2 car chargers. Excellent work, very responsive, easy to work with. read more

Ossamu, with OSJ Electric, knows his craft; definitely made the right choice in hiring him to install our Enphase batteries. He carefully planned and executed the installation, despite difficulties with a pre-existing gateway. Greatly appreciated his patience and professionalism in working with Enphase to resolve the technical glitch. Thanks to Ossamu, we're now able to bank our excess production for use during peak hours. Will certainly employ his services for future solar/electrical needs. read more

I called Ossamu to check out a power failure at my pool equipment. He ended up fixing that issue as well as power outage with outside plugs and another issue with my fuse tripping every time the pool heater turned on. He went above and beyond by recommending preventative things for the future. He even took a trip to the hardware store to pick up a little part for the outside plugs that I didn't even know needed replacement. He's super friendly and knowledgeable. I will be calling him again for future electrical needs!! Highly recommend **** read more

Ossamu and his business associates, Pablo and Wilfredo, are absolutely the best for electrical and other related work. The project involved installation of an EV charger in my garage which necessitated a new 220/240 circuit to be routed from the electrical panel to the opposite side of the house. The project was further complicated by the need to acquire, situate, install and transition to a 200amp electrical panel (from an original and fully utilized 100amp panel), moving some sprinkler control valves, and maneuvering through a tight crawl space. Scheduling had to be coordinated by Ossamu with PG&E and a county inspector. The project was done timely, with the highest level of care and quality, at a fair price, and with minimal disruption to my family. We have confidence in the results and appreciate the work Ossamu and team did at our home. They come highly recommended and we look forward to future opportunities to utilize their services. read more

We are extremely thankful for OSJ Electric. Our martial arts / dance studio's electrical system was in really bad shape, and OSJ came in, carefully looked at everything and fixed all the wiring system and upgraded all equipment, they did an amazing job. The quality was beyond what we expected. They are highly professional, reliable, dependable, and a very caring company. We couldn't be more pleased with their service. We highly recommend. read more

We chose OSJ electric to install our EV charging box. Ossamu was very professional, and very attentive to our needs and explained our options for amperages, etc. We never once felt like he was trying to sell us a product: which is what other EV installers did when we were getting quotes. I really appreciate his timeliness and attentiveness, and that he has local knowledge of the Lamorinda area permitting processes and his pricing is affordable and fair. We will hire Ossamu again in a heartbeat for our electrical needs, and we are thrilled that we have found a "gem" in the Lamorinda area. HIGHLY RECOMMENDED! read more
