Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in South Harwich homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“Storm took out our power for four days last winter. This year we have a standby generator that started itself while we were asleep.”
“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.”
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 South Harwich 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 South Harwich home sales, insurers and landlords.
