Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Mattapan homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Lost a furnace board and a TV in one storm. They put a surge device on the panel and explained exactly what it does and doesn't cover.”
“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.”
“They found a loose neutral that had been slowly cooking our appliances for years. Nobody else even looked for 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 Mattapan 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 Mattapan home sales, insurers and landlords.
