Best Lighting Retrofits in San Jose CA

As a retail owner in the Bay area for over 40 years and having experienced a number of contractors; non have been as conscientious as Main Stream Electric.
Their quality of work was excellent, done in a timely manner, reasonably priced and would highly recommend them for any type of electrical work needed.

They did my hot tub electrical work. Very reasonable price, professional, I will definitely use them again for some interior work I want to get done. I am a very happy customer.

I called Sonny because the electrical circuit breaker for my sump pump kept getting triggered, thus causing the pump to shut off and fail. Sonny replaced it and did a really good, solid job. I called him again to fix the other breaker and he came right away and charged a fair price.
