Gann Electric has been the electrician Arnold residents and Jefferson County businesses call when the wiring needs to be right. We service this area because we know the neighborhoods and the wiring in them. For 22 years, we have handled everything from a single dead outlet to a full commercial electrical installation, and we have built that track record one job at a time. Residential homeowners, property managers, and commercial clients all get the same thing from us: work performed by licensed electricians, clear communication from the first call, and an electrician who actually shows up. As locally owned and operated electricians, we are accountable to this community in a way that matters. One number. One call. One electrician at your door. Call (636) 746-4995 to get started.
We've handled everything from a flickering light to a full rewire, and every job in between has shaped how we work. Gann Electric was founded in 2004 by a local electrician who grew up in the area and wanted to build something the community could count on. That original commitment has not changed. The team has grown, the tools have improved, and the service area has expanded across Jefferson County, but the approach is the same: real electricians, real scheduling, and work done the way it should be done.
We treat your home and its wiring the way we would our own. That means we take care of your property on the job, explain what we find before we start, and leave the work clean when we finish. Whether you are a homeowner dealing with an electrical problem for the first time, a property manager coordinating repairs across multiple units, or a business owner who needs commercial electrical work done without disrupting operations, we fit the job to your situation.
Same-day and weekend scheduling are available when we have the capacity. We do not overpromise on timing, but we do work hard to get to you quickly. Give us a call and we'll get the power sorted.
No matter what's going wrong with your wiring, there is usually a clear cause, and finding it is what we do. Flickering lights, dead outlets, switches that stopped responding, and breakers that trip every time you run the microwave are all signs that something in the circuit needs attention. We troubleshoot the problem first, explain what we found, and give you a clear picture of what the repair involves before any work begins.
GFCI outlets in kitchens, bathrooms, and garages are a common repair call, and we handle installation and replacement of both GFCI and AFCI protection as part of our standard repair and safety work. These devices protect against shock and arc-fault hazards, and keeping them in working order matters for both code compliance and everyday safety.
We offer prompt response, even for last-minute electrical calls. If something goes wrong and you need an electrician today, call (636) 746-4995 and we will do our best to get someone out quickly. We'll make your wiring safe again.
Don't let a small wiring issue turn into a fire risk, and do not ignore a panel that is struggling to keep up with your home's electrical load. Older panels with undersized service, outdated breakers, or signs of overheating are a real concern, especially in homes that have added appliances, finished basements, or home offices over the years.
We handle panel replacement and upgrades, including the common 100-to-200-amp service upgrade that many Arnold homeowners need when their home's electrical demand has grown beyond what the original panel was designed to handle. We also install subpanels for detached garages, workshops, and additions, and we perform load calculations to make sure the new panel is sized correctly for the work it will carry. Grounding and bonding are part of every panel job, and all work meets current code requirements.
Commercial panel upgrades are part of the same expertise. If your business is adding equipment, expanding a space, or experiencing repeated breaker issues, a panel upgrade may be the right solution. Call today and we'll set the appointment.
Our customers call us back because we make wiring simple, and that is especially true for the bigger jobs. Older homes across Jefferson County were built at a time when the electrical demands were a fraction of what a modern household puts on a system. Knob-and-tube wiring, aluminum branch-circuit wiring, and undersized original wiring are all issues we address regularly. We handle whole-home rewiring, targeted wiring upgrades, and aluminum wiring remediation, and we do it with minimal disruption to the home.
New wiring for additions and remodels is another common call. Kitchen remodels, bathroom updates, basement finishing, and home additions all require electrical work that is planned correctly from the start. We run the circuits, install the outlets and switches, and coordinate with the rest of the project so the electrical side is done right.
Dedicated circuits for dryers, ranges, dishwashers, refrigerators, and other high-draw appliances are straightforward jobs that make a real difference in how reliably those appliances run. We install 240-volt outlets and dedicated appliance circuits for both new and existing homes. We take pride in the electrical work we leave behind, and that shows in how we run conduit, pull wire, and finish every connection. We'll get your lights back on fast.
Lighting work covers a wide range of jobs, and we handle all of it. Recessed lighting installation is one of the most common requests we get, and we handle everything from a single can light to a full room layout. LED lighting upgrades, ceiling light and fixture installation, and fixture replacement are everyday jobs for our team.
Ceiling fan installation and replacement are quick, clean jobs that make a noticeable difference in comfort and energy use. If you have a fan that needs to come down, a new one that needs to go up, or a box that needs to be upgraded to support a heavier fixture, we take care of the whole job.
Outdoor lighting is where safety and curb appeal meet. We install security lighting, motion-sensor lights, landscape lighting, and exterior fixtures for both residential and commercial properties. Under-cabinet lighting for kitchens is another popular request. Whatever the lighting project, we can get it on the schedule.
EV ownership in the Jefferson County area has grown steadily, and a Level 2 home charger is the practical solution for anyone who wants a full charge overnight rather than relying on a standard outlet. We install dedicated circuits and Level 2 EV charger outlets for all major vehicle brands, including Tesla charger installation for homeowners who need the right outlet or hardwired setup. We assess the panel, run the dedicated circuit, and install the outlet or charger mount so everything is ready when your vehicle is.
Missouri storm season is real, and power outages in Jefferson County can run longer than anyone wants. A properly wired generator transfer switch means you can run essential circuits safely when the grid goes down, without the risk of backfeed or overloading your panel. We handle the electrical side of generator hookups: the transfer switch installation, the wiring between the generator and the panel, and the load assessment to make sure the circuits you need are covered. Pick the date. We do the wiring. We clean up after.
A whole-home surge protector is installed at the panel and protects every circuit in the house from voltage spikes. Power strips with built-in surge protection only cover what is plugged into them. A panel-level device covers your appliances, electronics, HVAC equipment circuits, and anything else on the system. It is a straightforward installation that adds meaningful protection, especially in areas where storms and grid fluctuations are common.
Electrical safety inspections are useful in more situations than most people realize. If you are buying or selling a home, finishing a basement, renting out a property, or simply living in a house that has not had its wiring looked at in years, an inspection gives you a clear picture of what is working, what is not, and what may need attention. We check panel condition, grounding and bonding, outlet and switch function, GFCI and AFCI protection, and general wiring condition throughout the home. We also install hardwired smoke detectors and carbon monoxide detectors as part of our safety work.
We work with property managers, business owners, retail operators, and contractors who need commercial electrical work done on a schedule and done correctly. Commercial electrical repair, panel upgrades, lighting installation, and new circuit installation for offices and retail spaces are all part of what we do. We also handle the electrical work for commercial remodels and new construction, coordinating with general contractors and project timelines to keep things moving.
If you manage multiple properties or run a business that cannot afford extended downtime, we work with your schedule. Commercial clients get the same clear pricing and prompt communication as our residential customers, and the work is performed to the same standard.
Pricing is explained before any work begins. We assess the job, give you a clear quote, and do not add charges that were not part of the conversation. There are no surprise fees after the fact. If something unexpected comes up during the work, we stop, explain it, and get your approval before moving forward.
Same-day scheduling is available when we have the capacity, and we offer weekend appointments for customers who cannot take time off during the week. For electrical emergencies, we are available around the clock. The best way to find out what a job will cost and when we can get there is to call (636) 746-4995 directly.
Gann Electric was founded in 2004 by a local electrician who grew up in this area and wanted to build something the community could count on. The goal from the start was straightforward: real electricians, real scheduling, and work done the way it should be done. That original commitment has not changed in 22 years.
The electricians who show up at your door are the same team behind every job we schedule. Work is performed by licensed electricians who know what they are doing and take the work seriously. We do not subcontract out jobs or send unfamiliar crews to handle calls.
If something we worked on has a problem after we leave, call us. We stand behind the work we do, and we will come back to make it right. Our goal is that the job is done correctly the first time, but if it is not, we address it without making you argue for it.
Yes. We stand behind the work we perform. If a repair or installation we completed develops a problem related to our work, we come back and correct it. We take pride in the electrical work we leave behind, and that means being accountable after the job is finished.
We treat your home and its wiring the way we would our own. That means we take care of your property on the job, clean up when we are done, and leave the work area in good shape. We do not leave behind debris, packaging, or mess from the installation.
We start by listening to what you have noticed, then we trace the issue to its source before recommending anything. We explain what we find and give you a clear picture of what the repair involves. We do not recommend work that the situation does not call for.
Yes. Our trucks are stocked for the range of residential and commercial work we handle regularly, from small repairs to panel upgrades and wiring jobs. We bring what we need for the job so we are not making extra trips for common materials.
Gann Electric serves Arnold and the surrounding Jefferson County communities, including Barnhart, Festus, Crystal City, Hillsboro, Herculaneum, and Imperial. Whether you need a repair, an upgrade, or a full installation, we are ready to help. One number. One call. One electrician at your door. Call (636) 746-4995 to request a quote or get on the schedule.
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.
