The Verdict

SESCO handles complex electrical work well, but scheduling problems crop up often enough to make us wary. In one review, a homeowner took time off work for a 9 a.m. panel inspection, only to receive an email at 5 p.m. the night before saying the electrician couldn't make it and suggesting she call competitors after business hours. Another customer confirmed an appointment, then watched the clock tick past the window with no call, no show, no follow-up. We found 3 reviews describing missed appointments or radio silence, and several others mention difficulty reaching the office. When the crew does arrive, the work is solid. Hugo rewired a 2,000-square-foot house with knob-and-tube wiring, finishing on time with minimal plaster damage, while other electricians had balked at the scope. And 32 reviews single out the quality of installation and permitting work. But unreliable scheduling undermines even excellent craftsmanship, especially when you're coordinating inspections, realtor access, or time off work.

If you have schedule flexibility and can tolerate a potential no-show, SESCO's technical skills may be worth the gamble. But if you're taking time off work or coordinating with other trades, their track record for keeping appointments should give you pause.

3 Stories That Stood Out

1. Mateo L.
Yelp | Jul 12, 2012 |

Mateo L. called Sesco to book an electrical inspection for a Berkeley house he was buying. Regina answered but kept repeating the same property questions, explaining she was in the middle of something, which made an already anxious process feel disorganized. They set a 9 a.m. appointment a week out, a slot that required him to coordinate with the seller’s realtor and take the day off work to attend. Then, at 5 p.m. the night before the inspection, Regina messaged that their electrician couldn’t make it and handed him the names of two other electricians to call — an impractical solution when it’s after hours and the inspection was the next morning. He ended up scrambling to reschedule and losing the time off he’d planned. Mateo concluded that Sesco’s customer service and reliability failed him; from other reviews he gathered the crews might do solid work, but the night-before cancellation at 5 p.m. was the detail he wouldn’t forget when managing a time-sensitive home purchase.

2. Alexander K.
Yelp | Oct 27, 2023 |

Alexander K. needed to upgrade the knob-and-tube wiring in his 100-year-old, 2,000+ square-foot home and kept running into electricians who balked at the scope. They asked him to diagram circuits at the breaker and wouldn’t commit to taking on the whole house. He discovered Hugo, a contractor with decades of experience, who walked through the home for about 15 minutes, agreed to handle the job, and then finished on schedule. Hugo rewired all the switches, outlets, and lights with very minimal plaster damage, and also installed a dedicated outlet for the garbage disposal plus a 220V outlet. The most memorable part of the project: no homeowner pre-work, a quick on-site assessment, and a full, on-time rewiring that left hardly any visible repairs to fix.

3. Bookingood H.
Yelp | Dec 6, 2017 |

Bookingood H. arranged an on-site estimate with Sesco Electrical after a couple of phone calls with Virginia to set a time. When Hugo failed to arrive at the appointed hour, they called and left a message asking if he was still planning to come — and then heard nothing: no return call, no apology, no effort to reschedule. More than the missed appointment, what stuck with them was the silence afterward; a brief callback would have changed the whole impression. The unanswered call left them wondering whether Sesco prioritizes punctuality or customer communication.

What You Can Expect

01

1. Mary Ann B.
Yelp | Apr 1, 2018 |

Mary Ann B. chose Sesco after spotting its high rating in Consumers Checkbook. Over several years she had them handle multiple projects on her home, from large jobs to small repairs, and found the crews punctual, professional and personable. What stood out was their practicality: when a planned repair would have been expensive they laid out several lower‑cost options instead of automatically pushing the priciest fix. They weren’t the cheapest, but their reliability and willingness to explain choices kept her calling them back whenever a new job came up.

2. Alexander K.

3. Amy D.
Yelp | Dec 15, 2022 |

Amy paid Sesco more than $10,000 for a residential installation and ended up having to hire another company to redo the work. She discovered crossed wires in the electrical box that caused a shock, and the Ring camera she paid them to wire was left poorly installed rather than properly secured. When she pressed Virginia about those safety and quality problems, Virginia went silent. The crew billing also felt chaotic: she was quoted $120/hour each for Hugo and Oscar, but they showed up at 8 a.m. without knocking even though Amy lives next door to the site, then left — and she was billed $360 for that hour after tracking them down. She questioned the third worker Kevin’s license and was bullied into paying for him; meanwhile Oscar contradicted the charge, saying she should only be billed for two men. The crew left a filthy mess each day, including feces and standing water on the floor; when Amy asked Oscar to take their half-full bottles, he told her, "you can dump it." A homeowner who prefers hiring minority-owned businesses, she felt especially disappointed and ultimately stuck with the expense and risk of having someone else fix the dangerous, shoddy work.

1. Patrick O.
Yelp | May 2, 2016 |

Patrick O., an architect who has relied on Sesco Electrical for years, recently hired them to put solar panels on the roof of his 90-year-old home. He watched the crew work through the quirks of an older structure and ended up with an expertly executed installation that now offsets his household electricity — including charging his electric vehicle. Peitsa and Greg stepped in to handle every issue that surfaced, smoothing the process and keeping the project on track. The detail that sticks: a trusted local team adapted to an aging house and delivered a system that covers day-to-day use and EV charging.

2. Cynthia B.
Yelp | Jul 26, 2024 |

Cynthia called on Sesco—the electrical crew her heating contractor of 40 years used—when she needed new circuitry for recently installed heat pumps. The team arrived punctually, worked quickly and with care, and completed the job to a professional standard. The tricky part was running a metal conduit from one side of the house to the other without disturbing her deck; they figured out a routing solution that kept the deck intact. The technicians were personable, approachable, and able to work in both English and Spanish. She walked away with neat, expert wiring and the lasting impression that they solved the problem instead of making a mess of her outdoor space.

3. Chris B.
Yelp | Sep 4, 2023 |

Chris B. reached out after a different electrician had quoted $1,500 to repair an electrical issue on his solar equipment. He found the company responsive and appreciated that the crew took a straightforward, honest approach: they diagnosed the problem quickly, uncovered that the prior electrician had been overcharging, and applied a much simpler fix. He ended up paying $300 instead of the $1,500 he’d been told, a $1,200 difference that stuck with him. The standout detail was the clear, no‑nonsense diagnosis that turned an alarming estimate into a modest repair bill — the reason he plans to hire them again.

1. Meghan M.
Yelp | Jun 23, 2022 |

Meghan M. needed a quick service visit for her home’s solar system, and the company slotted her in with only one day's notice. The crew arrived promptly, worked efficiently, and tracked down a puzzling electrical fault that had been disrupting performance. What stuck with her was that they not only turned around the appointment quickly but stayed until the mystery was solved and the system was back to normal.

2. Yuji M.
Yelp | Dec 7, 2021 |

Yuji M. hired an electrical crew to install hallway lighting and discovered they completed the job quickly and cleanly for a reasonable fee. He appreciated the combination of speed, solid workmanship and fair pricing, and is already planning to call them back for more work.

3. Jin C.
Yelp | Jan 13, 2022 |

Jin C. called the company about flickering lights in the living room, bathroom and hallway; two technicians showed up at his hardwood‑floored home where the family doesn’t wear shoes indoors. They asked the technicians if they had shoe coverings; when the techs didn’t, they requested the workers remove their shoes — the technicians grumbled but complied. The two men spent only a few minutes staring at the problem areas, declared the solution was to "just replace the bulbs," ran no tests and offered no further explanation. They left after a very short visit and were charged $160; what stuck with them was that the crew seemed to spend more time taking shoes on and off than actually diagnosing the flicker.
