Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Groton homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“Sparking outlet in the nursery. They came out the same evening, replaced it, and checked every other outlet on that circuit for free.”
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“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 Groton 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 Groton home sales, insurers and landlords.
