Commercial Electrician across Altadena and Los Angeles County

EV charging, ADUs, central air added to older homes and all-electric remodels are driving panel upgrades across the Los Angeles area. In Altadena, the main question is usually capacity: whether the existing service can carry the new load or needs to move to 200 amps.

Our commercial electrician service also covers nearby Pasadena, La Canada Flintridge, Mount Wilson, San Marino, Sierra Madre and Montrose. ZIP codes served: 91001, 91003.

Commercial Electrician questions from Altadena customers

Will an LED lighting retrofit pay for itself?

In most offices, shops and warehouses it does, through lower energy use and far fewer lamp changes. We count fixtures, measure hours of use and show you the numbers before you decide. See lighting installation.

Do you offer ongoing electrical maintenance?

Yes. We set up scheduled visits for panel checks, lighting, exit and emergency lights, and equipment connections, with a written report after each one. An electrical inspection is a good starting point.

We lost power to part of the building. Can you come now?

Call (888) 633-7804. Commercial outages are treated as urgent, and our emergency electrician line is answered 24/7.

Can you work nights or weekends so we stay open?

Yes. Much of our commercial work in Altadena happens before opening, after close or over a weekend so your staff and customers are not disrupted.

From recent customers

We needed new circuits and lighting before opening our shop. Bayshore worked around our contractor's schedule and the inspection passed the first time.

Kevin O.Retail build-out

Our old 100 amp panel tripped every time the AC and dryer ran together. Bayshore quoted the 200 amp upgrade on the spot, handled the permit and had us back on by late afternoon.

Maria G.Panel upgrade

Half the house went dark at 9 pm and an outlet smelled hot. They talked me through shutting off the breaker and had someone at the door that night. He fixed a burned connection and checked the rest of the circuit.
