Does electrical work in Fenton require a permit?

Most projects do, yes. St. Louis County adopted the 2023 National Electrical Code in January 2025, and that code governs new circuits, panel upgrades, generator hookups, and EV charger installations within Fenton. Permits are pulled through the county's building department by a licensed electrical contractor, not by the homeowner, so that step is handled on your behalf when you book with Mr. Electric. Skipping the permit process creates real problems down the road. Home inspectors flag unpermitted electrical work during real estate transactions, and insurers can deny claims tied to it. A properly permitted job comes with an inspection sign-off that documents the work was done to code and protects you if anything comes up later.

What are some warning signs that my home's wiring needs attention?

A few patterns in particular are worth paying attention to. Outlets or switches that are warm to the touch, a burning smell near your electrical panel, lights that flicker when a large appliance kicks on, or breakers that trip more than once a month on the same circuit all point to wiring that may be undersized, damaged, or simply outdated for the demands of a modern household. Homes in Fenton built before 1980 sometimes still have aluminum branch circuit wiring or Federal Pacific panels, both of which carry well-documented safety concerns. If your house falls into that category and hasn't had an electrical inspection recently, scheduling one is worth doing before a small issue becomes a costly repair. Mr. Electric's team can assess the system and walk you through the options

Can you install a Level 2 EV charger at my home in Fenton?

Yes. A Level 2 charger runs on a dedicated 240-volt circuit and charges most EVs overnight, compared to the two or three days it can take at a standard 120-volt outlet. The U.S. Department of Energy estimates that Level 2 home charging equipment and installation averages $1,200 nationwide, though costs vary by region and home electrical conditions. Before installation, a load calculation confirms your panel has enough capacity to support the added circuit. Older Fenton homes with 100-amp service panels sometimes need an upgrade first. Mr. Electric handles the full scope: load assessment, circuit installation, permit, and inspection, so you're not coordinating multiple contractors.

What's the difference between a GFCI outlet and an AFCI breaker?

They protect against different hazards. A GFCI (ground-fault circuit interrupter) monitors current flow and cuts power in milliseconds if it detects a ground fault, which can cause electric shock near water. You'll find them in kitchens, bathrooms, garages, and outdoor locations. An AFCI detects dangerous electrical arcs that can be hidden in walls and cause fires, often from a nail puncturing a wire or a frayed appliance cord. Under the 2023 NEC, which St. Louis County now enforces, both protections are required in more areas of the home than in previous code editions. Some rooms need both on the same circuit, which a dual-function breaker provides in a single device. If your home was wired before these requirements were in place, an upgrade brings it into compliance with current standards.

Do you offer emergency electrical service in the Fenton area?

We do. Electrical problems that show up on a Saturday night or after a storm don't wait for Monday morning, and some of them genuinely can't. A burning smell from your panel, outlets that have stopped working after visible sparking, or a partial outage following severe weather are situations where waiting creates additional risk. Mr. Electric of St. Louis serves Fenton and the surrounding St. Louis County communities. When you call with an urgent issue, our team works to get to you quickly and diagnose the problem before it escalates. For non-urgent concerns, scheduling in advance is always an option.
