SESCO Electrical reviews

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.
Reviews That Shaped Our Verdict
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.
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.
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.

What You Can Expect
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.

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.
