"Armando, did an excellent job replacing the outdated fluorescent kitchen light fixtures, and replaced them with recessive energy efficient lighting. This included re-texturing the raised area as well as a finished coat of painting. Couldn?t be happier with the results!!!"

"I am an Electrical Engineer by education and trade, working for several high-tech firms in Silicon Valley over a 45-year career, so I've never felt the need to call an electrician. But I know my limits and repairing an electrical open circuit routed in underground conduit is one of them. After trouble shooting the issue, I knew there was a break in the line so I called Mike at M3 electrical. He put me on his schedule, showed up on that date (even a little early) and in less than two hours had the issue fixed. Not only that, but he advised the type of 2-wire Romex that had failed was not the proper wire for an underground application. He pulled about 75 feet of the proper wire through the conduit and even installed a junction box at my street light for a clean installation. Costly you think? Not in my opinion! If I ever need electrical work done in the future, Mike is the guy I will call. I suggest you do as well. Mark S. A very happy customer"
