Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Tewksbury 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.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“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.”
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 Tewksbury 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 Tewksbury home sales, insurers and landlords.
