Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Avon homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Two-prong outlets all through a 1920s house. They grounded what could be grounded and GFCI-protected the rest, then labelled everything.”
“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.”
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 Avon 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 Avon home sales, insurers and landlords.
