Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Norwood homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“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.”
“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.”
“Office fit-out on a tight deadline. They worked around our contractor, hit every date, and the inspection passed first 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 Norwood 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 Norwood home sales, insurers and landlords.
