Gann Electric has been the electrician Arnold, Jefferson County homeowners and businesses call since 2004. Whether you need a quick repair, a full panel upgrade, or wiring for a new addition, we handle it all. We work with homeowners, landlords, property managers, and commercial clients across the area, and we make ourselves available same-day, on weekends, and after hours when the job can't wait.
We service this area because we know the neighborhoods and the wiring in them. From older ranch homes in established Arnold subdivisions to newer builds and commercial properties along the corridor, we've seen the full range of what Jefferson County wiring looks like. Our locally owned and operated electricians show up on time, explain what they find, and get the work done right.
One number. One call. One electrician at your door.
Give us a call and we'll get the power sorted.
No matter what's going wrong with your wiring, we can track it down and fix it. Dead outlets, flickering lights, breakers that trip repeatedly, a breaker box that hums or runs warm. These are the calls we get every day, and they're the kind of problems that deserve a real diagnosis, not a guess.
When we arrive, we start by listening to what you've noticed, then we trace the issue to its source. We check circuits, test outlets, inspect the panel, and look at the wiring behind the problem. If a circuit needs an arc-fault or ground-fault breaker to bring it up to code, we'll tell you that before we do anything. You get a clear explanation and a quote before any work begins.
We take pride in prompt response, even for last-minute electrical calls. A tripping breaker or a dead outlet might feel minor, but left alone, small electrical faults can become bigger ones. Call us, describe what you're seeing, and we'll get someone out to you.
We'll make your wiring safe again.
We've handled everything from a flickering light to a full rewire, and the installation work in between covers a lot of ground. If you need new outlets, we install standard, GFCI, AFCI, USB-integrated, 240-volt, outdoor, and garage outlets. If your kitchen, bathroom, or garage is missing ground-fault protection, that's a straightforward upgrade we can take care of in a single visit.
For switches, we wire standard toggles, dimmers, and smart-switch-ready circuits so your home is ready for whatever controls you want to add. We also handle ceiling fan installation and wiring, including running new wiring to boxes that weren't designed for a fan.
Lighting is a big part of what we do. We install ceiling fixtures, recessed and can lighting, under-cabinet lighting, outdoor and landscape lighting, and security and motion-sensor lighting. Whether you're updating a single room or lighting an entire property, we size the circuits correctly and make sure everything is wired to code.
Call today and we'll set the appointment.
Don't let a small wiring issue turn into a fire risk. Older homes throughout the Arnold area were built in an era when electrical demand was a fraction of what it is today. Knob-and-tube wiring, aluminum branch circuit wiring, and undersized circuits are common finds in Jefferson County homes, and they need attention before they become hazards.
We handle whole-home rewiring when a house needs it, including knob-and-tube replacement and aluminum wiring remediation. For homes that just need more capacity in specific areas, we run dedicated circuits for dryers, stoves, refrigerators, dishwashers, and workshop equipment. A 240-volt circuit for a new appliance or a basement sump pump circuit are the kinds of jobs we schedule regularly.
Before we run any new wiring, we do the load calculations. That means the new circuit is sized correctly for what it feeds, the grounding and bonding are done properly, and the finished work meets current code. We treat your home and its wiring the way we would our own.
We'll get your lights back on fast.
Jefferson County's four-season climate puts real demand on homes and their electrical systems. Hot summers, cold winters, and a storm season that brings severe thunderstorms, tornadoes, and ice storms make certain electrical upgrades more than a nice-to-have. Older housing stock throughout the Arnold area adds another layer. The three services below come up constantly in this region, and we handle all of them.
Many homes in the Arnold area were wired for 100-amp service, which made sense decades ago but falls short of modern demand. Today's households run multiple large appliances, home offices, and increasingly, EV chargers. An older panel can't always carry that load safely. We perform 200-amp service upgrades, service panel replacements, and commercial panel upgrades, and we start with a proper load calculation so the new panel is sized for what the home actually needs. If your panel is running warm, has breakers that won't reset, or simply can't support what you're plugging in, an inspection and upgrade quote is the right first step.
Power outages in Jefferson County are a real seasonal concern. Severe storms knock out service for hours or days, and when that happens, a properly wired standby generator makes a significant difference. We handle the electrical side of generator installation: the transfer switch, the panel connection, and all the wiring that lets a generator take over safely when utility power goes down. We don't sell generators, but we wire them correctly so they work when you need them. Call for a quote and we'll walk you through what the installation involves for your home or business.
A power strip with a surge rating offers limited protection. A whole-home surge protector installed at the service entrance is a different level of defense. It catches voltage spikes before they reach your wiring and the appliances, electronics, and equipment connected to it. In an area that sees the kind of storm activity Jefferson County does, a single lightning-related surge can cause serious damage to everything plugged into your home. Installation is straightforward and the protection is immediate. It's one of the more cost-effective upgrades we recommend to homeowners here.
Our customers call us back because we make wiring simple, and that applies to commercial clients just as much as homeowners. We work with small businesses, property managers, retail spaces, offices, and warehouses throughout the Arnold area. Commercial wiring, panel upgrades, lighting installation, and circuit work for remodels and renovations are all part of what we do.
If you're building out a new space, updating an existing one, or adding circuits to handle new equipment, we handle the planning and the execution. We take pride in the electrical work we leave behind, and commercial clients notice that when inspections go smoothly and the work holds up over time.
Call today and we'll set the appointment.
An electrical safety inspection gives you a clear picture of where your wiring stands. We perform inspections for homeowners who want peace of mind, buyers who want to know what they're getting before closing, and property managers who need to document the condition of a unit. We look at the panel, the circuits, the outlets, the grounding, and the visible wiring throughout the home.
If we find code violations, we explain what they are, why they matter, and what it takes to correct them. GFCI and AFCI protection in the right locations, properly grounded outlets, and a panel that's up to current standards are the most common items we address after an inspection. We also install hard-wired smoke detectors and carbon monoxide detectors where they're needed.
Knowing the condition of your electrical system before a problem develops is always worth the visit.
A Level 2 home EV charger requires a dedicated 240-volt circuit and, depending on your current panel, may require a capacity upgrade before the charger can be installed. We handle the full electrical side of EV charger installation: running the circuit, installing the outlet or hardwired connection, and verifying that your panel can carry the added load without issue.
We work with all major charger brands and handle the wiring for Tesla home chargers and other Level 2 units. If you're not sure whether your panel has room, we'll check during the visit and give you a clear answer before any work starts. Call for a quote and we'll tell you exactly what your installation involves.
We'll get your lights back on fast.
Electrical problems don't always happen at convenient times. We offer same-day service when our schedule allows, and we're available on weekends and after hours for situations that can't wait until Monday morning. If something feels urgent, call us and describe what you're seeing. We'll tell you honestly how quickly we can get there and what to do in the meantime.
The process is simple. You call, we listen, we schedule the visit, and we show up when we said we would.
Pick the date. We do the wiring. We clean up after.
Call today and we'll set the appointment.
Electrical work varies in scope, and pricing reflects that. A single outlet repair costs less than a panel upgrade, and a full rewire is a different conversation than a ceiling fan installation. We don't publish flat rates because the right price depends on what the job actually involves.
What we do offer is a clear quote before any work begins. You'll know what the job covers and what it costs before we touch anything. No surprises when the work is done. Call for a quote and we'll give you a straight answer.

Homes built before the 1980s in Jefferson County may have knob-and-tube wiring, aluminum branch-circuit wiring, or circuits that were never sized for modern electrical demand. If your home has not had its wiring looked at in years, or if you are experiencing repeated electrical problems, an inspection is the right first step. We will tell you clearly what we find and what, if anything, needs to change.
It helps to know roughly what you are experiencing, which area of the home is affected, and whether the problem is ongoing or intermittent. You do not need to have a diagnosis ready. We will ask the right questions on the call to figure out what kind of visit makes sense and how quickly we need to get there.
We listen to what you describe, ask a few questions to understand the scope, and get you on the schedule. When we arrive, we assess the situation, explain what we find, and give you a quote before any work begins. The process is straightforward from the first call to the finished job.

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.
