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.

I would give 0 stars if it was possible. Very bad and careless service. They don't have any value or respect for their customers and do not take any responsibility for badly done job. Please avoid choosing this contractor.

Their technician replaced the incorrectly installed ceiling fan plastic mount with a proper metal mount in our kids' bedroom and assured us that this will not cause any further issues. He charged a total of $317 for this job. After less than 2 weeks, when my 1 year old daughter was taking her afternoon nap alone in the room, we heard a loud and disturbing noise. When we ran inside, we saw that the fan had fallen off the (newly installed) mount and was just hanging by a screw. We were shocked and terrified to see this. We were very lucky that it did not cause any serious problems to our daughter, but at the same time we were so frustrated and disappointed with this careless job that was done with replacing the mount.

When I called up Tri-valley Electrical and left a message with the receptionist about this incident, at first they did not respond for 2 days (thinking that I will just forget it and let it go). Finally after 4 days, I got to speak to the owner and she sent a technician to inspect if it was their problem or not. Next day, she called up and first said that they will not refund any money but can fix it back again for free. When I said that I do not want your service again and asked them for refund, so that I can get the job done through more reliable contractor, they just refused. After lot of arguing she is only agreeing for refunding $135 (against $317 charged). How is this fair?

They are not showing any sensitivity that my daughter was present in the bedroom when this incident happened.
