Pick what you're noticing. We'll tell you what it usually means, how urgent it is, and what fixes it.

Safety first

Burning Smell, Scorch Marks or Sparks

A burning or hot-plastic smell from an outlet, switch or the panel usually means wiring or a connection is overheating.

If you see smoke, sparks or flames, get everyone out and call 911. If it is safe to reach, switch off the affected breaker or the main. First Choice Electric is not an emergency service; once the area is safe, book a repair visit and we will find and fix the cause.

Common causes

  • Loose or overheated connection
  • Overloaded circuit
  • Failing breaker or panel bus
  • Damaged wiring inside a wall

Signs You Need This

Lights flicker or dim unexpectedly
Flickering indicates loose connections, voltage fluctuations, or overloaded circuits. Persistent flickering is a fire hazard.
Breakers trip repeatedly
A breaker that won't stay reset has a reason: overload, short circuit, ground fault, or failing breaker. Don't just keep resetting it.
Burning smell with no visible source
Electrical burning smells often come from wiring overheating inside a wall. If you see smoke or flames, get out and call 911. If it is safe, switch off the breaker for that area and leave it off. We are not an emergency service, but book a repair and we will prioritize it.
Outlets or switches feel warm
Heat indicates resistance from loose connections or overloading. Both are fire hazards that need immediate attention.
Sparks when plugging in devices
Occasional small sparks can be normal, but frequent or large sparks indicate worn contacts or wiring problems.
Buzzing or crackling sounds
Electrical arcing makes buzzing or crackling sounds. This is actively damaging wiring and is a fire hazard.
Partial power loss in home
If half your home loses power, you may have lost a leg of your 240V service or have a loose main connection.
GFCI outlets won't reset
A GFCI that won't reset may have found a ground fault, but it can also mean no power is reaching it, the line and load wires are reversed, or the device has failed. Each needs a different fix, so have it tested.

How It Works

From First Visit to Final Inspection

Typical job: 1-4 hours.

  1. Problem Description

    When you call, describe the symptoms: flickering lights, tripping breakers, dead outlets, burning smells. Tell us when it happens (always, sometimes, under certain conditions) and what changed recently. This helps us prepare the right tools.

  2. Safety Assessment

    When we arrive, we first assess whether there's an immediate safety hazard. If we find dangerous conditions (burning smells, arcing, extreme heat), we may need to shut off power before proceeding with diagnosis.

  3. Systematic Testing

    We use professional diagnostic equipment (circuit analyzers, voltage testers, clamp meters, and sometimes thermal imaging cameras) to systematically test the affected circuits and identify where the problem originates.

  4. Root Cause Diagnosis

    We trace the problem to its source: a loose connection, failing breaker, damaged wire, overloaded circuit, or faulty device. We explain what we found and why it's causing your symptoms.

  5. Repair Options

    We present your options with clear pricing. Some problems have simple fixes; others may require more extensive work. We explain the pros and cons of each approach so you can make an informed decision.

  6. Professional Repair

    Once you approve, we complete the repair using proper materials and techniques. We don't just patch problems. We fix them correctly so they don't return.

  7. Testing & Verification

    After the repair, we test thoroughly to verify the problem is solved. We test related circuits, check for any secondary issues, and ensure everything works safely before leaving.

What we see

Damage We Find, and Why It Happens

  • Scorched receptacle pulled from the wall with burnt wiring in O'Fallon

    O'Fallon

    Overheated Receptacle

    A loose connection behind the plate arcs under load. The heat builds until the device chars.

    We find the loose connection, replace the device and any heat-damaged wire, and check the rest of the circuit.

  • the burn mark on the panel bus behind a failed breaker in St. Charles, MO

    St. Charles

    Burnt Panel Bus

    Heat from a failing breaker scorches the bus bar it sits on. The damage spreads to the neighbouring circuits.

    We replace the panel; a burnt bus cannot be repaired.

  • a breaker melted by overheating in a St. Charles, MO panel

    St. Charles

    Melted Breaker

    A loose or overloaded breaker runs hot. The plastic case and the bus bar behind it melt before anything trips.

    We shut the panel down, replace the damaged breaker and bus, and in a case like this the whole panel.

  • an overcrowded panel with doubled-up circuits in Overland, MO

    Overland

    Overcrowded Panel

    Two wires under one breaker and no spare slots mean overloaded circuits and loose connections.

    We rebalance the circuits onto a new, larger panel.

  • corroded, overheated breakers in an Overland, MO panel

    Overland

    Corroded Breakers

    Moisture and age corrode breaker contacts. Corroded breakers run hot and may not trip when they should.

    We replace the breakers, or the panel when the bus is affected.

  • a burnt receptacle found behind the cover plate in Overland, MO

    Overland

    Burnt Receptacle

    A worn receptacle or a loose backstab wire arcs behind the cover plate until the device chars.

    We replace the device, check the wiring behind it and the rest of the circuit.

FAQ

Questions About Electrical Troubleshooting & Wiring Repair

Why do my lights flicker?

Flickering can be caused by loose connections, overloaded circuits, faulty fixtures, or utility issues. We'll diagnose the specific cause.

Why does one breaker keep tripping?

A breaker trips when there's an overload, short circuit, or ground fault. It could be too many devices, a failing appliance, or a wiring problem.

Is it dangerous if outlets feel warm?

Warm outlets can indicate loose connections or overloading, both fire hazards. Have them checked promptly.

Why do I hear buzzing from my panel?

Buzzing can indicate loose connections, failing breakers, or overloaded circuits. This should be inspected as it can be a fire hazard.

Do you offer same-day service?

We are not an emergency service, but urgent issues get priority. Tell us what is happening when you book and we will fit you in as soon as the schedule allows, usually within 1-3 business days.

How do you find hidden electrical problems?

We use circuit testers, thermal imaging cameras, and systematic testing to locate problems behind walls without unnecessary demolition.

What if the problem is intermittent?

Intermittent problems are common and often indicate loose connections that only fail under certain conditions. We test under load to catch these issues.

Can electrical problems cause fires?

Yes. Loose connections, overloaded circuits, and damaged wiring are leading causes of house fires. Prompt troubleshooting prevents disasters.
