The company serves residential and commercial clients throughout the Bay Area, handling everything from outlet installations to full-scale electrical upgrades for renovation projects. Customers consistently praise the team for professionalism, punctuality, and fair pricing without hidden fees.

The contractor specializes in electric vehicle infrastructure, with documented experience installing NEMA 14-50 outlets, Tesla wall connectors, and commercial-grade charging stations. Reviews also highlight complex residential work including main electrical panel upgrades, subpanel installations for kitchen remodels, and low-voltage systems. One particularly ambitious project involved complete electrical installation for a historic building restoration in Manteca, covering indoor and outdoor lighting, fire safety systems, data cabling for seven units, and a 24-camera security network.

Multiple reviewers specifically credit a technician named Raja (also referenced as Rajan) for exceptional service across various electrical needs. Customers describe same-day arrival, fast completion times, and thorough explanations of work performed. One client noted Raja handled a Tesla wall connector installation while another praised his panel upgrade work, with both emphasizing his knowledge, attention to code compliance, and guidance through the city permitting process.
