"Nery and his team are top notch. They replaced a sub panel in our new townhome, added a 20v breaker and also fixed some outlets that had really bad wiring. The first two tasks were already agreed upon and the 3rd was something they helped out with on a whim thankfully. Nery came multiple times to our Oakland home to provide estimates for different options we were considering. He gave us different ideas and was very professional. They arrived around 11am and were done by a little after 6pm. Their work was very clean and they pay a lot of attention to detail. I highly recommend them and have already shared their information with our entire HOA. I found them on Angi's list and am so glad I did! As first time homeowners, Nery was very reasonable in working with our budget. We can't recommend them enough!"

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"I hired M3 Electrical to install a charger for an electric vehicle. The distance from the outside breaker box was quite a distance, requiring him to run conduit a long way. The work Mike did was extremely neat. I was very impressed. I would not hesitate to use M3 in the future for all my electrical needs."

"Had to have additional circuits added to my panel, some wiring, plugs and GFCI outlet. Hamilton Electric did a professional job quickly and efficiently. Brian explained everything along the way and made sure I was satisfied. He is honest and fair, old school, the way service used to be. Price was great, too."
