Gann Electric has been handling residential and commercial electrical work in Arnold since 2004. Whether you need a fast repair, a full panel upgrade, or wiring for a new addition, we show up ready to work. We serve homeowners, landlords, property managers, and business owners throughout Jefferson County, Missouri. Prompt response, even for last-minute electrical calls, is something we take seriously. Same-day availability is not always guaranteed, but we do our best to get to you quickly when something goes wrong. One number. One call. One electrician at your door.
No matter what's going wrong with your wiring, the first step is figuring out exactly what's causing it. A diagnostic visit means we look at the full picture, not just the symptom. Flickering lights might be a loose connection, a failing breaker, or something deeper in the circuit. A dead outlet could be a tripped GFCI, a wiring fault, or a breaker that's on its way out. We track it down and fix it right.
Common repair calls we handle:
We treat your home and its wiring the way we would our own. That means we do not guess, we do not patch over problems, and we do not leave until the issue is resolved. We'll make your wiring safe again.
Our customers call us back because we make wiring simple, and nowhere is that more true than with the everyday upgrades that make a home or business more functional. Installing a new outlet, replacing a worn switch, or adding a ceiling fan in the right room can make a real difference in how a space works.
For indoor work, we handle outlet and switch installation and replacement, GFCI outlet upgrades, ceiling fan installation and wiring, recessed and LED lighting, under-cabinet lighting, and bathroom exhaust fan wiring. For outdoor work, we install security lighting, motion sensor lights, landscape lighting, and exterior fixtures of all kinds.
Whether you are refreshing a single room or updating lighting across an entire property, we can handle it efficiently. Call today and we'll set the appointment.
We've handled everything from a flickering light to a full rewire, and the wiring section of a home tells us a lot about what a property has been through. Jefferson County has a solid mix of housing stock, including homes built in the mid-twentieth century that may still have knob-and-tube wiring, aluminum branch wiring, or circuits that were never sized for modern electrical loads. We assess what is there, explain what needs to change, and do the work to bring it up to current standards.
Dedicated circuits are one of the more common jobs we run for both homeowners and rental properties. Major appliances need their own circuit to run safely and reliably. We install dedicated circuits for:
We take pride in the electrical work we leave behind. Code-compliant wiring done cleanly is not just about passing inspection. It is about the home being safe for the people living in it. Give us a call and we'll get the power sorted.
Jefferson County sees a full range of Missouri weather. Summers bring heat and heavy storms. Winters bring ice and the occasional hard freeze. Tornado season is real, and so are the power outages and surge events that follow a bad storm. We service this area because we know the neighborhoods and the wiring in them. The three services below come up regularly for good reason.
Older homes in the Arnold area were often built with 60-amp or 100-amp service panels, sized for a time when households ran far fewer appliances. Today's loads, including EV chargers, high-draw kitchen appliances, and modern HVAC systems, can push an aging panel past its capacity. We perform load calculations to determine what your home actually needs, then handle the full upgrade including service-entrance work and, where needed, subpanel installation. A properly sized panel keeps your circuits from being overloaded and makes adding future loads much simpler.
Missouri storm season can knock power out for hours or days at a time. A backup generator is only useful if it is wired correctly and connected through a proper transfer switch. We handle the electrical side of generator hookups: running the dedicated circuit, installing the transfer switch, and making sure the connection is safe and code-compliant. Whether you are adding a hookup for a portable generator or wiring in a standby unit, we do the electrical work to make it reliable when you need it most.
A plug-in surge strip protects one outlet. A panel-level surge protection device protects the entire home. In an area that sees frequent thunderstorms and lightning, that distinction matters. A single surge event can damage appliances, electronics, and HVAC equipment in seconds. We install surge protection devices at the panel so that the protection is there before the power reaches any outlet in the house. It is one of the more cost-effective things you can do for a home full of modern electronics.
Don't let a small wiring issue turn into a fire risk. Electrical safety inspections are useful in more situations than most people realize. Home buyers want to know what they are getting into before closing. Landlords need to confirm that rental units meet code before a new tenant moves in. Insurance carriers sometimes require documentation of the electrical system's condition. We perform thorough inspections that cover panel condition, grounding and bonding, GFCI and AFCI protection, outlet and switch condition, and visible wiring throughout the home.
If an inspection turns up items that need correction, we can handle the repairs the same visit or schedule a follow-up. We'll get your lights back on fast.
Electric vehicle ownership is growing steadily in the St. Louis metro area, and Arnold is no exception. A Level 2 home EV charger requires a dedicated 240-volt circuit sized for the charger's output. Before we run that circuit, we check your panel's available capacity and confirm it can handle the added load without creating problems elsewhere in the home. If an upgrade is needed, we handle that too. The result is a clean, code-compliant charger circuit that keeps your vehicle charged overnight without putting stress on the rest of your electrical system. Call for a quote and we will walk you through what the installation involves.
Our customers call us back because we make wiring simple, and that applies just as much to commercial accounts and rental portfolios as it does to single-family homes. Businesses need electrical work done efficiently and with minimal disruption. Property managers need a reliable electrician who can respond quickly across multiple units. We handle both.
We work with:
We are locally owned and operated electricians, and that means the person you call is the same team that shows up. Work performed by licensed electricians, completed on schedule, and done to code. Call for a quote and let us put together a plan for your property.
Electrical pricing depends on what the job involves. Scope, materials, panel size, circuit length, and site access all factor into a final number. A simple outlet replacement costs far less than a full-panel upgrade, and a whole-home rewire is a different conversation than running a single dedicated circuit. We will give you a clear picture of what the work involves and what it will cost before anything gets started.
Pick the date. We do the wiring. We clean up after.

We serve Arnold and the surrounding Jefferson County area, including Barnhart, Festus, Crystal City, Herculaneum, Imperial, Hillsboro, Byrnes Mill, and High Ridge. If you are in the area and need an electrician, we are close by and ready to schedule.
A panel that runs warm, has breakers that will not reset, shows signs of scorching or corrosion, or simply cannot support the circuits you need is telling you it has reached its limit. Many homes in the Arnold area were built with 60-amp or 100-amp service, which is not enough for modern electrical loads. If you are experiencing repeated breaker trips or cannot add circuits without overloading the panel, a panel assessment is the right call.
Breakers trip because a circuit is drawing more current than it is rated for, which is the protection working as intended. If a breaker trips once after you overload an outlet, that is usually not a concern. If a breaker trips repeatedly under normal use, or if it trips and will not reset, that points to a wiring fault, a failing breaker, or a circuit that is undersized for what it is feeding.
A Level 2 charger requires a dedicated 240-volt circuit sized for the charger's output. Before we run the circuit, we check your panel's available capacity and confirm it can handle the added load. We install the dedicated circuit, the outlet or hardwired connection, and verify that everything is code-compliant. If a panel upgrade is needed first, we handle that as part of the same project.
Sparking outlets, burning smells coming from a panel or outlet, a breaker that trips and will not reset, visible scorching on wiring or devices, and a complete loss of power to part of the home are all situations that warrant a prompt call. If you are not sure whether something is urgent, call us and describe what you are seeing. We will tell you honestly how quickly we need to respond.
We offer same-day service when our schedule allows and are available every day from 8:00 AM to 11:00 PM. For situations that feel urgent, call (636) 746-4995 directly and we will do our best to get someone to you as quickly as possible.
A whole-home surge protector is installed at the service panel and catches voltage spikes before they reach any outlet or circuit in the house. A plug-in surge strip only protects what is connected to it. In Jefferson County, where thunderstorms and lightning are a regular seasonal occurrence, a single surge event can damage appliances, electronics, and equipment throughout the home. Panel-level protection covers everything at once and is one of the more cost-effective upgrades we recommend.
We start by listening to what you have noticed, then we trace the issue systematically. We test outlets, check the circuit at the panel, inspect the wiring path, and look for the root cause rather than just the visible symptom. We explain what we find before recommending any repair so you understand what the problem actually is.
Homes built in the mid-twentieth century were wired for a fraction of the electrical load a modern household puts on a system. Circuits that were sized for a few lights and a television cannot safely handle today's kitchen appliances, home offices, and entertainment equipment. Adding outlets without adding circuits just spreads the same limited capacity further. The real fix is dedicated circuits and, in many cases, a panel upgrade.
Yes. When the scope of work requires a permit and inspection, we handle that process. Code-compliant work that passes inspection is the standard we hold ourselves to, and we do not skip the steps that are required to get there.
We install the transfer switch, run the wiring between the generator and the panel, and assess the load to make sure the circuits you need covered are included in the hookup. The transfer switch is what allows the generator to power your home safely without the risk of backfeed to the utility line. We handle the full electrical side of the installation whether you are adding a hookup for a portable unit or wiring in a standby generator.
For most wiring work, panel work, and circuit installation, yes. We shut off the relevant circuits or the main service to work safely. We let you know ahead of time what will be without power and for how long so you can plan accordingly. For smaller jobs like outlet or switch replacements, the outage is typically brief and limited to the affected circuit.
Twenty-two years of electrical work in this community means we have seen the wiring challenges that come with Missouri homes and Missouri weather. Gann Electric is ready to take your call, get to your property, and handle the job correctly. Call (636) 746-4995 today to get a quote or schedule a visit. We'll make your wiring safe again.
From a tripped breaker to a full-home rewire, we handle the electrical work Arnold homeowners and businesses need most. The table below lays out what each service covers, who it fits, and what to keep in mind before you call. Every job gets a clear quote before we start, and we show up when we say we will.
| Service Type | Scope of Work | Common Situations | Things to Know |
|---|---|---|---|
| Backup Generator Installation |
| Jefferson County homeowners and businesses who lose power during severe storms or ice events | A correctly wired transfer switch is required by code and prevents dangerous backfeed onto utility lines. |
| Whole-Home Surge Protection |
| any homeowner in a storm-prone area who wants to protect electronics and appliances from voltage spikes | A whole-home unit catches surges before they reach your wiring. A power strip alone does not offer the same level of protection. |
| EV Charger Installation |
| EV owners who want faster home charging than a standard 120-volt outlet provides | We check panel capacity first. If an upgrade is needed before the charger can be installed safely, we will tell you upfront. |
| Outlet & Switch Installation |
| homeowners adding outlets or upgrading older ungrounded receptacles | GFCI protection is required by code in kitchens, bathrooms, garages, and outdoor locations. |
| Ceiling Fan Installation |
| homeowners replacing a light fixture with a fan or adding a fan where none existed | Boxes not rated for a fan's weight need to be replaced before installation. We handle that as part of the job. |
| Breaker & Fuse Repair |
| homes with an aging panel or circuits that cannot hold their load | A breaker that keeps tripping is telling you something. We find the cause before replacing hardware. |
| Electrical Repairs & Troubleshooting |
| any homeowner or business with an unexplained electrical problem | Small faults can grow into bigger ones. A prompt diagnosis is always safer than waiting. |
| Older-Home Rewiring |
| owners of older Jefferson County homes with outdated or unsafe wiring | Aluminum branch wiring and knob-and-tube are both fire-risk concerns that insurers increasingly flag. |
| Lighting Installation |
| homeowners updating a room or property managers improving exterior security | We size circuits correctly so new fixtures do not overload an existing branch. |
| Electrical Safety Inspections |
| buyers, sellers, landlords, and homeowners who want a clear picture of their wiring | If we find issues, we explain what they are and what it takes to correct them before we recommend any work. |
| Wiring & Circuit Installation |
| homeowners finishing a basement, adding a room, or renovating an existing space | All new wiring is sized and installed to current code and is ready for inspection. |
| Electrical Panel UpgradesMost Popular |
| homes with 100-amp service, aging panels, or plans to add EV chargers or major appliances | A proper load calculation before the upgrade ensures the new panel is sized for what the home actually needs now and in the future. |
| Dedicated Appliance Circuits |
| anyone adding a large appliance or moving equipment to a new location | A dedicated circuit prevents nuisance tripping and protects the appliance from shared-load fluctuations. |
How do I know if my panel needs to be upgraded?
Common signs include breakers that trip under normal load, a panel that runs warm or hums, breakers that will not reset, or a 100-amp service that cannot keep up with modern demand. If your home has an older fuse box or a panel brand with a known history of problems, an inspection is a smart first step. We look at the panel, do a load calculation, and give you a straight answer about whether an upgrade makes sense.
What causes a breaker to trip repeatedly?
Repeated tripping usually means a circuit is carrying more load than it was designed for, there is a fault somewhere in the wiring or a connected device, or the breaker itself is worn out and no longer holding its rating. We trace the problem to its source rather than just resetting the breaker and hoping it holds. Ignoring repeated tripping is not a safe option.
Is older wiring in Jefferson County homes a safety concern?
It can be. Homes built before the 1980s may have knob-and-tube wiring, aluminum branch-circuit wiring, or circuits that were never sized for today's electrical demand. Neither type is automatically dangerous if it is in good condition, but both require a careful inspection. Knob-and-tube has no ground conductor, and aluminum wiring connections can loosen and overheat over time. We inspect what is there and tell you clearly what needs attention.
Upfront Quotes With No Surprise Fees
We give you a clear quote before we touch anything, and if the scope does not change, the price does not change. If something unexpected comes up during the work, we stop and talk to you first.
Do I need to be home when the electrician arrives?
For most jobs, yes. We need access to the panel, the affected circuits, and often multiple areas of the home. If you have a specific situation where you cannot be present, call us and we will talk through what is possible. For commercial properties, a building manager or property contact works just as well.
How does pricing work, and will the quote change once work starts?
We give you a clear quote based on what the job involves before we start anything. If the scope does not change, the price does not change. If we find something unexpected during the work, we stop, explain what we found, and get your approval before moving forward. You will not see charges at the end that were not part of the original conversation.
Are you available same-day or after hours for electrical problems?
We offer same-day service when our schedule allows, and we are available on weekends and after hours for situations that cannot wait. If something feels urgent, call us, describe what you are seeing, and we will tell you honestly how quickly we can get there and what to watch for in the meantime.
Same-Day and Emergency Availability
Electrical problems do not always happen at convenient times. We are available same-day, on weekends, and after hours for situations that cannot wait.
What do I need for a Level 2 EV charger at home?
A Level 2 charger requires a dedicated 240-volt circuit sized for the charger's amperage, typically 40 to 50 amps. Depending on your current panel, you may also need additional capacity before the circuit can be added safely. We check the panel first, confirm whether an upgrade is needed, and give you a full picture of what the installation involves before any work begins.
Why would I need a whole-home surge protector if I already use power strips?
A surge-rated power strip protects the devices plugged into it, but it does not stop a large voltage spike at the service entrance from reaching your wiring and every outlet in the house. A whole-home surge protector installed at the panel intercepts surges before they travel through your circuits. In an area that sees the storm activity Jefferson County does, that added layer of protection is worth considering.
Experienced With Older and Newer Homes
We have worked on the full range of Jefferson County housing, from older ranch homes with knob-and-tube wiring to newer builds needing added capacity. We know what to look for and how to fix it right.
What is involved in a backup generator hookup?
The electrical side of a generator installation includes a transfer switch, the wiring between the switch and your panel, and the connection to the generator itself. The transfer switch is what allows the generator to power your home safely without backfeeding onto utility lines, which is a code requirement and a safety issue. We handle all of that wiring. We do not sell generators, but we wire them correctly so they work when you need them.
When should I call an electrician instead of handling something myself?
Swapping a light bulb or resetting a tripped breaker is fine. Anything beyond that, including replacing outlets, adding circuits, touching the panel, or investigating a wiring problem, should be handled by someone who knows what they are looking at. Electrical faults can cause fires and shock hazards that are not always obvious. Work performed by licensed electricians also meets code, which matters for insurance and resale.
What does an electrical safety inspection cover?
We look at the panel, the circuits, the outlets, the grounding, and the visible wiring throughout the home. We check for code violations, missing GFCI and AFCI protection, improperly grounded outlets, and any signs of overheating or damage. At the end, we explain what we found, what it means, and what it would take to correct anything that needs attention. There is no obligation to proceed with repairs after the inspection.
