Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Green Harbor homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Breaker had been tripping for months and two other companies just replaced parts. OSB traced it to a backstabbed outlet behind a bookcase in twenty minutes.”
“We had knob-and-tube in the attic and our insurer was getting nervous. They rewired in stages so we never lost power for more than a few hours at a time.”
“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.”
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 Green Harbor 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 Green Harbor home sales, insurers and landlords.
