Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Chelsea homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“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.”
“Sold our house and the buyer's inspector flagged eight electrical items. OSB fixed all of them in one visit and wrote it up so we could close on time.”
“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 Chelsea 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 Chelsea home sales, insurers and landlords.
