Most electrical "mysteries" in west Contra Costa homes have a small number of root causes: a loose wire-nut connection in a junction box, a bad breaker, an aluminum-to-copper splice that has corroded, a backstabbed outlet that has lost contact, a shared neutral that has come undone in the wall. The symptom (flickering lights, dead outlets, breaker trips) is rarely where the problem actually is.
A diagnostic call is exactly that — diagnostic. We come out with a multimeter, an outlet tester, an infrared camera if needed, and a circuit tracer. We walk the symptoms, we map the affected outlets, we open the obvious junction points, and we find the fault. Most diagnostics take 30 to 90 minutes on site. We then tell you exactly what is wrong and what it costs to fix it.
If you decide to have us do the repair on the same visit, the diagnostic charge is credited toward the repair. If you decide to call another electrician or do nothing, you owe us the diagnostic fee and nothing else. We do not do hard sells.
Dead circuit / dead outlets Tripped breakers, failed connections, GFCI tripped further upstream, neutral failures
Frequent breaker trips Overloaded circuits, bad breakers, ground faults, arc faults, AFCI nuisance trips
Flickering or dimming lights Loose neutrals, poor grounds, voltage sag, bad bulbs, incompatible dimmers
Burning smells Overheating connections, failing breakers, arcing inside walls — call us immediately and turn off the affected circuit
Buzzing or humming panels Loose breaker connections, failing main breaker, harmonic distortion from inverter loads
GFCI keeps tripping Moisture intrusion, downstream wiring fault, GFCI itself failing, miswired outlet downstream
