Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Cummaquid homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
That's the job. We isolate circuits, test under load and trace the run until the actual fault shows itself — no guessing, no parts cannon.
Three causes: overload, short circuit, or ground fault. Each has a different fix, and testing tells us which one it is within the first visit.
Most Cummaquid repair calls are handled same-day, and emergencies are dispatched 24/7 at (833) 652-8933.
There's a flat diagnostic fee quoted on the phone, and it's credited toward the repair when you go ahead.
Yes. We produce written inspection findings for Cummaquid home sales, insurers and landlords.
