Not every electrical problem is obvious. A breaker that trips for no clear reason, an outlet that's dead but the breaker looks fine, lights that flicker in one room only — these take real diagnostic work, not guesswork or a parts-swap-and-hope approach.
We trace the circuit, test at the source, and find the actual cause before touching anything — then explain what we found and what it'll take to fix it, in plain language, before starting the repair.
What troubleshooting costs
$250 – $350Diagnostic visit — most faults are found within the first hour
Diagnostic visit$250 – $350
Our service-call minimum. We trace the fault and give you a price in writing before fixing anything. Go ahead with the repair and this comes off the bill. Median: $280.
Typical single-circuit repair$250 – $600
Found and fixed in the same visit in most cases. Median: $380.
Complex or intermittent faultsQuoted after diagnosis
Multi-circuit tracing simply takes longer — you get the price in writing once we know what we're chasing.
You pay for the diagnosis once: if you go ahead with the repair, the $250 comes off the final bill. Planning a project instead? Estimates for panel upgrades, EV chargers, remodels and other planned work are free — the $250 minimum applies to service calls, when something needs to be diagnosed or fixed.
These ranges are a starting point, not a quote. The exact price for your job can only be set after we talk it through — call or send the form and you’ll have it as a free written estimate before any work starts.
Ranges taken from our own paid invoices, August 2024 – August 2026. 36 diagnostic visits, 14 extended service calls.
Who this is for
Something's clearly wrong — tripping breakers, dead outlets, flickering or dimming lights — but the cause isn't obvious
Another electrician swapped parts without actually finding the problem, and it's back
You're buying or selling a home and want an unbiased read on an electrical issue an inspector flagged
A circuit works intermittently and you need someone who'll actually track it down, not just reset the breaker

01My breaker keeps tripping and I don't know why — can you find out?
Yes — that's exactly what troubleshooting calls are for. We trace the circuit and test at the source instead of guessing.
02Another electrician already tried and it's still happening — is it worth calling you?
Often, yes. Intermittent faults can take real diagnostic time to catch; a quick parts swap sometimes just masks the symptom.
03Do you charge just to diagnose the problem?
Yes — a diagnostic visit is a paid service call with a $250 minimum, which covers getting there and the first hour of tracing the fault. If you go ahead with the repair, that $250 comes off the final bill, so you only pay for the diagnosis once. Any repair is quoted separately in writing before we fix anything. Estimates for planned projects — panels, EV chargers, remodels — are free.
04Can you troubleshoot without opening up walls?
In most cases, yes — circuit tracing and testing find the fault without unnecessary demolition.
05I'm buying a house and the inspection flagged an electrical issue — can you take a look?
Yes, we can assess a flagged issue and give you a straight, unbiased read on what it actually needs.
06What if the problem turns out to be bigger than expected?
We'll tell you exactly what we found and quote the fix before doing any further work — no surprises.

During a complex commercial renovation in Portland, our electricians completed trim work including outlet and light fixture installation, plus troubleshooting switch power issues.
Addressing electrical panel issues is not routine when water intrusion is involved. This project required both a careful upgrade and attention to moisture concerns at the weather head entering the meter main. We documented the work throughout, ensuring clear wiring, secure connections, and organized panels for safety and efficient power distribution.
