Moved to the Livermore area in 2013. Home purchase. First home even. Tri-Valley Electrical Service installed network cabling in our house. They took care of electrical zoning changes later. (Splitting the bathrooms to a different circuit breaker than the secondary bedrooms-- the PCs and the vacuum on the same breaker kept tripping so splitting the breakers was the only option unless we wanted to run extension cords everywhere.) Speaking of that they were also very helpful in documenting the breaker zones in our house when they were doing the work (going above and beyond). They also installed ceiling fans in bathrooms and laundry to vent moisture. My only regret is that they don't have a roofing contractor partner who can complete the ducting work. (The fans vent into the attic and do not have a backdraft flap-- I would have preferred them to vent to the exterior of the building and have a backdraft flap.) They also assisted later with a kitchen renovation and lighting changes we made with the house. (The company that did the renovation had subpar electricians on-staff and we pulled them in to help solve those issues.)

I plan to call them again soon for some other electrical repair.

I've dealt with a number of different businesses since buying my first home and even with the exception above, this company always comes to mind as one of the better experiences I've had since becoming a home owner.

Stephen installed my ceiling fans today. He was great!! Very respectful of my house and my dog. I have hard wood floors, and he was very careful of them with the ladder. He was quiet while I was on conference calls off and on, and willing to chat about dogs when I wasn't. My fans were all installed and tested to make sure they don't rattle. He was a professional the entire time he was here. I'd highly recommend Tri Valley Electrical to everyone!!!

My highest compliments to Sean! He fixed a problem with my spa electrical that has been plaguing me for years. His trouble-shooting and isolation of the issue was first class! His customer communication and professionalism was also first class. My highest compliments to Sean and Tri-Valley electrical. I will be calling you for every electrical need going forward!

Honest business that does well by its customers. Another electric co. Budget Electric dispatched by the home warranty company said that the problems was a fried wire behind the wall and that it was caused by circuit overload, and that all the drywall would have to come out and be replaced. Major $$, but denied by the home warranty company because reported as ""circuit overload"". Tri Valley owner Ron answered the emergency phone line everytime it was called (3 X), even the day before Christmas eve when they were closed. His guy came out and fixed a loose connection behind the panel and the problem was solved quickly.

Now understand, I don't give 5's, I give 4's but Tri-Valley Electrical is a definite 5 Star operation. We were referred to Tri-Valley through our home warranty to repair the wiring to our Evaporative Cooler. Well, the wiring and conduit was shot and needed to be restrung from the circuit breakers back to the cooler. Sean was our electrician and he is AWESOME!! The job took much longer then he expected and he had other calls scheduled after us. At this point, many technicians would incomplete the call for ""a part"" so that they could make it to the next call, but not Sean. He stuck with the job until it was fully completed. Sean is absolutely a professional with a great work ethic and he is totally committed to Quality on every call. They say that you can judge an organization by the people they employ. Going forward, should I ever need an electrician, Tri-Valley Electrical will be the first and only call I will need to make. And to Sean, Cheers

Tri-Valley Electrical Service is FANTASTIC! We had the pleasure of Meeting Ron to have our Home electrical main panel breakers replaced. Jim came out to our home and the job was done very fast and complete. Our home is 25 years old and we had breakers that were old, and no longer readily available. Jim replaced all of the breakers, re-labeled our panel and left with 2 very happy customers. His prices were competitive and fair, and as he told us, no job is to small! A BIG thank you Tri-Valley Electrical Service.

Just bought a new house in the East Bay and not even a week in it and we have electrical issues.It's an older house sooo i mean duh... it's expected. Had some issues with our doorbell and our ceiling fan in our breakfast nook and we had to call someone else. It was wobbling and shaking pretty loud. Tri-Valley is BUSY we almost got pushed out a month until someone miraculously cancelled. Thanks unknown customer! Bright and early on Monday morning (today) we had Jim M at our door. He was super professional and friendly. Working at this spot on and off since 1992 (says he). And he was professional to boot. Tightened up our kitchen ceiling fan in a matter of minutes and cleaned/greased our exhaust fan in a jiffy. I would highly recommend these guys if you have any issues with electric work in your home. Thanks for your great work Jim! We will use again, hopefully not any time in the near future.

We had tri-valley come out to a newly purchased home to work on a main electric panel that needed quite a bit of help, not the least of which included moving it outside of the firewall, and to restore power to a circuit (it turns out the wires were not attached to the panel in a previous ""repair""). Ron came out and checked out the main job, and we got to ask him about a few other minor repairs as well in the garage. A quote was provided within a couple of days, and we were scheduled for the work about a week later. Any questions that came up: we just called and got quick answers.
The work was splendid. The previous main panel was a rat's nest of wires, and the tri-valley guys cleaned it up so that you could easily trace paths. They replaced a couple of improperly installed breakers (wrong amperage for given wire gauge), they added some junction boxes where required in the garage, and installed a GFCI in the bathroom. Once the power was returned to the mains, they checked out each circuit, including the ones that had no power before. They also checked the main appliances (e.g., washer, dryer, oven, stove, dishwasher, etc.) to make sure that there were no problems with the wiring.
All-in-all, I was very happy doing business with Tri-Valley. The electrician even called me back that night to check after my satisfaction with the job. These guys pay attention to their work, they do great work, and the business side of the house was easy to work with. I found the overall price to be fair given the scope of the work and the reasonably quick scheduling.

Great service. Sean came out to fix my doorbell. I know it's minor compared to some other repairs, but still, I couldn't figure it out. Sean fixed it and went out of his way to accommodate. Very professional, polite, and would definitely go through them again.
