Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Sunderland homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“Two-prong outlets all through a 1920s house. They grounded what could be grounded and GFCI-protected the rest, then labelled everything.”
“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 Sunderland 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 Sunderland home sales, insurers and landlords.
