Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Watertown homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Storm took out our power for four days last winter. This year we have a standby generator that started itself while we were asleep.”
“They rewired our restaurant kitchen overnight so we never closed a single service. That mattered more than the price, honestly.”
“Every smart switch I bought failed because there was no neutral. They pulled neutrals in the rooms that needed it and set up the rest properly.”
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 Watertown 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 Watertown home sales, insurers and landlords.
