Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Wellesley 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.”
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
“Fan on a vaulted ceiling that two handymen said couldn't be done. Right downrod, right box, level and silent.”
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 Wellesley 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 Wellesley home sales, insurers and landlords.
