Electrical Wiring Services in St. Louis

Whole-Home Rewiring Services Throughout St. Charles & St. Louis Counties

Your home's wiring is one of those things that works quietly in the background until it doesn't. For most homeowners, it never comes up unless something goes wrong. What's easy to forget is that the wiring in your walls was installed for the home as it existed at the time, not the home you live in today. Additions, renovations, upgraded appliances, and years of increased electrical demand all take a toll on a system that was never designed to account for them.

Potts Electric handles wiring installation and whole-home rewiring for homeowners throughout the St. Louis metro. Whether you're dealing with a specific problem circuit, planning a room addition, or considering a full rewire on an older property, our licensed team can deliver the services you need with the quality you deserve.

Is Your Home’s Wiring Safe? Common Signs It’s Time to Rewire

Electrical problems aren’t always obvious—until they become inconvenient or dangerous. If you live in an older home in the St. Louis area, outdated wiring may not be able to keep up with modern electrical demands from appliances, HVAC systems, EV chargers, and home offices. Potts Electric, LLC helps homeowners identify hidden hazards and complete wiring upgrades that improve safety, reliability, and peace of mind.

Warning signs you should schedule a wiring evaluation:

  • Flickering or dimming lights when appliances turn on
  • Warm outlets, switch plates, or a burning smell
  • Frequent breaker trips or blown fuses
  • Buzzing sounds from outlets, switches, or the panel
  • Two-prong outlets, missing grounding, or no GFCI protection in kitchens/baths
  • Overuse of extension cords because there aren’t enough outlets
  • Aluminum wiring, knob-and-tube wiring, or other older wiring types

What to Expect When You Hire Potts Electric, LLC

We make rewiring and new wiring projects in  St. Louis straightforward. After assessing your home’s electrical system, we’ll explain your options in clear terms and recommend improvements that align with your goals—whether that’s a safer panel setup, better circuit distribution, or preparing for future upgrades.

  • Safety-first approach: We look for overloaded circuits, improper connections, and grounding issues.
  • Code-conscious workmanship: We focus on proper protection where it matters most, such as AFCI/GFCI requirements and correct circuit sizing.
  • Cleaner, less disruptive upgrades: We plan routes and access points to minimize drywall impact whenever possible.
  • Future-ready planning: Add capacity for renovations, hot tubs, kitchen upgrades, or EV charging so you’re not rewiring twice.

Not sure if you need a full rewire? Many homes only need targeted circuit additions, outlet upgrades, or corrections to problem areas. Contact Potts Electric, LLC to schedule an evaluation and get a clear plan for your home in the St. Louis-area counties.

Rewiring Older and Historic St. Louis Homes

St. Louis has an unusually large stock of homes from the late 1800s and early 1900s, especially in neighborhoods like Soulard, Lafayette Square, Benton Park, Compton Heights, and the Central West End, along with older sections of Webster Groves and Kirkwood. These homes were often wired decades before modern electrical demand existed, and many still carry some combination of knob-and-tube wiring, aluminum branch circuits, or a patchwork of updates made by different owners and electricians over the years.

  • That patchwork is exactly what makes older-home rewiring different from a standard job. It's rarely one clean system to replace. It's usually several generations of wiring layered on top of each other, sometimes with a newer panel connected to older circuits that were never fully updated. Before any work begins, our rewiring pros in St. Louis trace the home's electrical history room by room so nothing gets missed or reconnected to wiring it shouldn't be tied to.
  • Plaster walls and older construction methods common in these neighborhoods also call for a different approach than a newer build. We plan routing carefully to minimize the impact on original trim, plaster, and finishes, since those details are often part of what makes these homes worth preserving in the first place. The goal is a home that's fully safe and code-compliant on the inside, without losing the character that drew you to it in the first place.

Quality Garage Wiring Solutions in St. Louis

Garage wiring gets overlooked more than almost any other part of a home's electrical system, in part because garages were often an afterthought when many St. Louis-area homes were originally built. It's common to find a detached garage running off a single circuit shared between the lights and one or two outlets, with no dedicated power for anything beyond a garage door opener.

That setup falls short fast once a garage starts doing more than storing cars. A workshop with power tools, a chest freezer, a Level 2 EV charger, or even just a couple of space heaters in the winter can overload a single old circuit quickly. Code requires at least one dedicated 20-amp receptacle circuit for any garage with power, separate from the lighting circuit in most cases, and older garages frequently don't meet that standard.

Detached garages carry an extra layer of consideration. The feeder running from the house has to be sized and grounded correctly, and older detached garages, especially on properties with garages built or wired well before current code, sometimes lack proper grounding entirely. We evaluate the existing feeder, confirm what the garage actually needs based on how you use the space, and either add circuits or install a dedicated subpanel when a garage's workload calls for one. That's especially common now as more St. Louis homeowners want the garage to handle an EV charger alongside everything else already plugged in out there.

What a Whole-Home Rewire Actually Involves

A whole-home rewire in St. Louis isn't just swapping old wire for new. 

  • It starts with an inspection of your entire electrical system, including the panel, every circuit, and how power is currently distributed room to room, so we understand exactly what we're replacing and why. 
  • From there, we plan a route that gets new wiring where it needs to go with as little disruption to your walls and finishes as possible.
  • We walk through the timeline and cost with you before anything starts, and for homes where a full rewire isn't necessary yet, we'll say so and recommend targeted circuit upgrades instead.

Common Questions About Wiring & Rewiring in St. Louis

How Do I Know if My Home Needs to Be Rewired?

Frequent breaker trips, flickering lights, burning smells, discolored outlets, and outlets that have stopped working are all warning signs of faulty wiring. Additionally, homes with knob-and-tube or aluminum branch wiring, or any home where significant DIY electrical work has been done, benefit from a professional evaluation regardless of visible symptoms.

Does Rewiring Require Opening up Walls?

In most cases, yes, though the extent varies based on the home's construction and the scope of the work. Our St. Louis rewiring team takes care to minimize disruption and clean up thoroughly after every job.

How Long Does a Whole-Home Rewire Take?

Most whole-home rewires in St. Louis on a single-family residence take between three and seven days, depending on the home's size and the complexity of the existing system. We can provide a clear timeline before work begins.

How Much Does It Cost to Rewire an Older Home in St. Louis?

Cost depends mainly on the home's size, how many stories it has, whether walls are plaster or drywall, and how much of the existing wiring needs to come out versus be added to.

Older homes with plaster walls and finished basements, common throughout South City and older parts of St. Louis County, typically take more careful work to route around than a newer build, which affects the estimate.

We walk through your home in person and provide a clear quote before any work begins, so you're never guessing at the number.

Can I Rewire Just Part of My Home Instead of the Whole House?

Yes, and for many homes, a partial rewire is the right call rather than an unnecessary full replacement. We commonly target the highest-demand areas first, kitchens, bathrooms, and laundry rooms, while evaluating whether the remaining circuits are safe to leave as is for now.

The one exception is homes where the goal is resolving an insurance requirement tied to knob-and-tube wiring, since most carriers require it removed from active service entirely, not just in high-use rooms, before they'll issue a standard policy.

Is It Normal for an Older St. Louis Home to Have Several Types of Wiring?

Yes, and it's actually more common than not in homes throughout the city's older neighborhoods. A home built in the early 1900s may have had knob-and-tube originally, aluminum wiring added during a 1960s or 70s update, and modern copper mixed in from more recent renovations, all coexisting in the same house.

Before we start any wiring project in St. Louis, we trace what's actually there room by room rather than assuming the panel tells the whole story, since in older homes it frequently doesn't.

What's the Difference Between Knob-and-Tube, Aluminum, and Copper Wiring?

  • Knob-and-tube wiring, used from the 1880s through the 1940s, runs individual wires through ceramic knobs and tubes with no ground wire, which is why it falls short of modern safety standards.
  • Aluminum wiring, common in homes built or updated in the 1960s and 70s, expands and contracts more than copper as it heats and cools, which can loosen connections over time and create a fire risk at outlets and switches.
  • Copper wiring is the modern standard because it's more stable, supports proper grounding, and holds up reliably under today's electrical loads.

If you're not sure which type your St. Louis home has, our inspections can help.
