Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Humarock homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Called at 11pm when half the house went dark and an outlet was making a noise I'd never heard before. Someone was at the door in under an hour and had it isolated before midnight.”
“Our panel was original to the house and completely full. OSB upgraded us to 200 amp, pulled the permit, met the inspector, and left the basement cleaner than they found it.”
“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 Humarock 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 Humarock home sales, insurers and landlords.
