Hidden faults,
found and fixed.

A breaker that keeps tripping. Half a room with no power. Lights that flicker when the dryer kicks on. We find the problem — usually in under an hour — and we tell you what it actually costs to fix.

Symptoms with a real cause behind them.

Most "mysteries" in west Contra Costa homes trace back to a loose wire nut, a backstabbed outlet, a corroded aluminum splice, or a broken shared neutral. The symptom (flicker, dead outlet, trip) is rarely where the fault actually lives.

A diagnostic is 30–90 minutes on site with a multimeter, an outlet tester, and a circuit tracer. We find the fault, tell you what it costs to fix, and credit the diagnostic toward the repair if you want it done the same visit. No hard sells.

What's in every troubleshooting job

  1. Dead circuit / dead outlets Tripped breakers, failed connections, GFCI tripped further upstream, neutral failures
  2. Frequent breaker trips Overloaded circuits, bad breakers, ground faults, arc faults, AFCI nuisance trips
  3. Flickering or dimming lights Loose neutrals, poor grounds, voltage sag, bad bulbs, incompatible dimmers
  4. Burning smells Overheating connections, failing breakers, arcing inside walls — call us immediately and turn off the affected circuit
  5. Buzzing or humming panels Loose breaker connections, failing main breaker, harmonic distortion from inverter loads
  6. GFCI keeps tripping Moisture intrusion, downstream wiring fault, GFCI itself failing, miswired outlet downstream

On site, instruments out, fault found.

  1. 01

    You call

    Tell us the symptom and where in the house it is happening. We confirm the trip charge and the diagnostic rate before we roll a truck.

  2. 02

    On-site walk

    We walk the affected area, test the outlets and switches, and check the panel for tripped breakers and obvious signs.

  3. 03

    Open the obvious points

    Failing junctions are usually in the affected room or the room directly upstream on the circuit. We open switch and outlet boxes, check connections, and use a circuit tracer if needed.

  4. 04

    Identify the fault

    Loose wire nut, backstabbed outlet, broken neutral, failing breaker, bad GFCI, corroded splice — we tell you what we found and where.

  5. 05

    Tell you what it costs to fix

    Usually we can fix it on the same visit. Some repairs need parts we have on the truck; others need a return visit.

  6. 06

    Diagnostic credit

    If you have us do the repair, the diagnostic fee is credited toward the repair labor.

Troubleshooting — billing tiers

The diagnostic fee is credited toward the repair labor if we do the fix on the same visit. If you decide to call another electrician or do nothing after we identify the fault, you owe the diagnostic and nothing else. No hard sells.

  • Fix-and-go (1hr min) Outlet, light, small breaker — resolved inside the first hour

What it usually turns out to be.

  1. Backstabbed outlet failure Mid-2000s tract homes used "backstab" outlets where the wire pushes into a hole behind the device. They fail at the contact point — the outlet stops working, sometimes the whole downstream chain goes with it.
  2. Loose neutral in a multi-wire branch circuit A failed neutral on a shared circuit causes voltage to swing wildly between the two halves — half the kitchen runs at 80V, the other half at 160V. Lights flicker, bulbs burn out, and electronics get damaged.
  3. Corroded aluminum splice Aluminum-to-copper splices made with the wrong connector corrode, develop high resistance, and eventually fail. Symptom is a dead chain of outlets in one room.
  4. Overloaded shared circuit A microwave and a toaster on the same circuit will trip the breaker every time. Sometimes the fix is a new dedicated circuit; sometimes it is just being aware of the load.
  5. Failing breaker Older breakers (especially in Federal Pacific or Zinsco panels) fail in the closed position — the breaker looks fine but is not actually delivering power downstream.
  6. GFCI tripped two rooms away A GFCI in a bathroom can protect a downstream outlet in the garage. When the garage outlet stops working, the fix is resetting the bathroom GFCI — saved you a service call.

Troubleshooting questions, answered.

How much does a diagnostic call cost?

Between $180 and $350 for most west Contra Costa homes. The wider range covers a longer or more complex diagnostic. We confirm the rate on the phone before we roll a truck.

Will the diagnostic charge be credited if I have you do the repair?

Yes. If we do the repair on the same visit, the diagnostic fee is credited toward the repair labor.

Can you fix it on the same visit?

Usually. We carry common parts on the truck — outlets, switches, breakers, wire nuts, GFCIs, AFCI breakers. For larger or specialized parts we may need a return visit.

Do you do emergency calls?

We are open Mon–Fri 8a–5p for normal service. For genuinely dangerous situations — burning smells, sparking panels, exposed live conductors — call us anyway and we will triage.

What if the fault is intermittent?

Intermittent faults are the hardest to chase, and we are honest about that on the phone. Sometimes the fix is replacing the suspect part empirically; sometimes we need to wait for the symptom to be present to find it. We tell you what we recommend.
