Pennsylvania Electricians is an independent contractor-referral service that connects Pennsylvania homeowners, landlords, and property managers with participating independent electricians. This page covers electrical repair and troubleshooting: the problems homeowners call about most, what usually causes them, how an electrician finds the fault, and what affects the price.
What electrical repair covers
Most residential repair calls are about something that stopped working or started acting strangely: a circuit with no power, lights that flicker, an outlet that's warm, a switch that buzzes, or part of the house going dark. The repair itself is often small, like a loose connection, a failed device, or a damaged cable. Finding it is the skilled part, and that's what you're paying an electrician for.
- Outlets, switches, or fixtures with no power
- Lights that flicker, dim, or brighten
- Buzzing, crackling, or a hot smell at a device
- Part of the house without power when nothing has tripped
- Breakers that trip or fuses that blow (see circuit breaker repair)
- Damage after a renovation, a nail through a cable, or a rodent problem
- Problems a home inspector flagged
Electrical troubleshooting: how the cause gets found
Troubleshooting is the step between "something's wrong" and the repair. An electrician starts with what you've noticed, then tests: which outlets and lights are on the affected circuit, whether voltage is present and steady, whether a GFCI or AFCI device has tripped somewhere upstream, and where along the circuit the fault sits. In older Pennsylvania houses, circuits often wander through rooms in ways the panel labels don't match, so mapping the circuit is part of the job.
Some faults are intermittent, like a loose connection that only fails when the furnace starts or a space heater runs. Writing down when the problem happens (time of day, what was running, the weather) can save time. No one can diagnose an electrical problem from symptoms alone, and an electrician won't be able to promise a cause over the phone.
Common causes behind repair calls
These are the usual suspects. Which one applies takes testing to confirm:
- Loose connections at outlets, switches, splices, or the panel. They cause flicker, heat, and intermittent power, and they're a common source of arcing.
- "Backstabbed" outlets, where wires are pushed into the back of the receptacle instead of wrapped on the screws. The connection can loosen over time.
- A tripped GFCI in another room, often a bathroom, garage, or basement outlet that also protects outlets downstream.
- Failed devices. Outlets, switches, and dimmers wear out.
- Overloaded circuits that were laid out for far less than they carry today.
- Damaged cable from nails, screws, rodents, or past DIY work.
- Problems at the service or panel, including a loose neutral, which can make lights brighten and dim across the house. That one needs attention quickly, and sometimes the utility.
Why older Pennsylvania houses need more troubleshooting
In Reading, 57 percent of homes were built before 1940; in Lancaster, 54 percent; in York, 49 percent (U.S. Census Bureau, ACS 2020–2024). Houses that old have usually been rewired in pieces: original knob-and-tube in one part, 1950s cloth-covered cable in another, modern cable where someone remodeled. Junction boxes get buried in plaster and splices get hidden in walls. That makes faults harder to trace and repairs slower, and it's why a repair visit sometimes turns into a conversation about rewiring.
When to call an electrician
- A circuit stays dead after you've checked for a tripped breaker and pressed the reset button on any GFCI outlets
- Lights flicker or dim in more than one room, or when large appliances start
- An outlet, switch, or cover plate is warm, discolored, or buzzing
- You get even a mild shock from a switch, outlet, or appliance
- Part of the house has no power and nothing has tripped
- There's a hot or burning smell. If there's smoke or sparking, leave and call 911 first
What electrical repair costs
Angi's 2026 data puts the average electrician job at $351, with most falling between $163 and $538. Hourly rates run $50 to $130, and most electricians charge a $100 to $200 service call or first hour. Emergency and after-hours visits often cost about double. Angi's Philadelphia figures run slightly higher, averaging $377. See the Pennsylvania electrician cost guide for more.
- How long it takes to find the fault
- Plaster or finished walls that have to be opened and patched
- Whether the cause is one device or a damaged run of cable
- Old wiring that has to be corrected before the repair can be finished
- Permits for anything beyond a like-for-like repair
- Night, weekend, or same-day timing
What you can safely do before the electrician arrives
- Check the obvious once. Look for a tripped breaker and press the reset button on any GFCI outlets. Reset a tripped breaker one time only.
- Unplug anything on the affected circuit, especially heaters and appliances.
- Stop using any outlet or switch that's warm, discolored, or buzzing.
- Write down what happens and when: what was running, which rooms are affected, any smell or sound.
- Don't open the panel or take covers off. Leave testing to the electrician.
Questions to ask an electrician about a repair
- How do you charge: flat rate, hourly, or a service fee plus time?
- If you find a bigger problem, will you stop and give me a price before going further?
- Does this repair need a permit?
- Pennsylvania has no statewide electrician license. Does my municipality require one for this work, and what's your license number if so? What's your PAHIC registration number?
- Will you patch the openings, or should I plan for a plasterer or drywall finisher?
