Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Sudbury 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.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
“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.”
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 Sudbury 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 Sudbury home sales, insurers and landlords.
