Most homeowners can't tell a minor wiring issue from a serious one, and that uncertainty is exactly why a prompt call matters. A flickering light might be a loose connection at the fixture. A breaker that keeps tripping could point to an overloaded circuit or a failing breaker. A burning smell near an outlet or panel is never something to wait on. Partial power loss in one part of the house often traces back to a tripped breaker, a bad connection, or a problem at the panel itself.
We trace the fault before anything is replaced. That means you understand what went wrong and why before any work begins. We're ready to get your circuits working again.
Some calls are urgent. No power in part of the house, a sparking outlet, a burning smell that won't go away, or a breaker that won't reset and won't stay on - these are situations that should not sit on a list until Monday. We take short-notice work and answer calls every day from 8:30 AM to 8:00 PM. When you reach us, you get a real person who can scope the problem on the phone and tell you what to expect before anyone shows up.
A tripped breaker that won't reset, outlets that stopped working in one room, or a switch that sparks when you flip it all point to specific faults that can be diagnosed and repaired. GFCI and AFCI protection play a role in both diagnosis and repair, and grounding and bonding issues often surface during this kind of work. Code-compliant wiring on every job means the repair is done to current standards, not just patched to get the lights back on.
A lot of homes in Arnold and Jefferson County were built when 100-amp service was standard. With central air, electric ranges, EV chargers, and the rest of the load a modern household puts on a panel, that original capacity runs short fast. A panel upgrade or service upgrade adds the headroom a home actually needs. We handle load calculations, breaker box replacement, 200-amp service upgrades, and subpanel installation when a detached garage or finished basement needs its own feed.
The process starts with understanding what the existing panel is carrying and what the new load will require. The scope and the price are confirmed before any work is scheduled.
Wiring a home right takes the right tools and a careful hand, and older homes in Arnold and the surrounding Jefferson County area often need more than a spot repair. Knob-and-tube wiring, aluminum branch circuit wiring, and cloth-sheathed cable all present problems that a panel upgrade alone won't fix. Whole-home rewiring replaces the branch circuits throughout the house. Partial rewiring targets specific areas, a basement, a kitchen, or an addition, where the existing wiring is no longer adequate. We assess what is there before recommending how much needs to come out.
An electric dryer, a range, a refrigerator, or a hot tub each draws enough current that sharing a circuit with other loads creates real problems. A dedicated circuit runs directly from the panel to a single outlet or connection point with no other devices on the line. We size the circuit to the appliance, confirm the panel has capacity for the new load, and wire it to code. For any heating or cooling unit that requires a dedicated circuit, we handle the electrical supply side: the circuit, the disconnect, and the panel capacity to carry it.
Seeing flickering lights or a warm outlet? Those are the calls that start with a quick diagnosis and often turn into a straightforward installation or replacement. We handle outlet installation and replacement, GFCI and AFCI outlet upgrades, USB outlets, standard switch replacement, dimmer installation, and three-way switch wiring. We show up ready to wire, which means the job gets done in the visit rather than stretched across multiple trips.
A new light fixture changes how a room reads. Recessed lighting adds clean, even coverage without the bulk of a surface-mounted fixture. Under-cabinet lighting makes a kitchen more functional. We handle the wiring, the box work, and the fixture installation, and we confirm the circuit can carry the new load before anything goes up. These are jobs that improve a room and add real value to a property.
Outdoor lighting does more than improve curb appeal. A well-placed motion sensor light at a garage or entry door adds visibility and discourages opportunistic problems. Landscape lighting extends how a yard looks and functions after dark. We run the wiring, install the fixtures, and make sure everything is weatherproofed and connected correctly. Exterior electrical work is harder to revisit once it is buried or enclosed, so each connection and seal is checked before the job is closed out.
A ceiling fan installation is straightforward when there is already a switched outlet box in the right location. When there is not, we run the wiring and install a fan-rated box before the fixture goes up. Replacing an older fan follows the same process: confirm the box, check the wiring, and install to current standards. Call us and the rest is handled.
Missouri's four-season climate brings real demand on electrical systems from both ends. Severe thunderstorms, tornadoes, and ice storms roll through Jefferson County with enough regularity that backup power and surge protection are practical decisions, not optional extras. Older homes in Arnold carry their own set of electrical demands as loads grow and panels age. Local means we care what the neighbors think, and that shapes how we approach every job in this area.
Arnold's housing stock includes a significant number of homes built before modern electrical loads were a consideration. Add the draw from central air during a Missouri summer, an EV charger in the garage, and a finished basement, and an older 100-amp panel is working well past its intended capacity. A panel upgrade replaces the existing equipment with a properly sized service, adds breaker capacity for current and future loads, and brings the main disconnect up to current code. We confirm what the panel needs to carry before sizing the replacement.
Jefferson County sees power outages during storm season, and some of them last long enough to matter. A standby generator installation on the electrical side involves a transfer switch, a dedicated circuit from the panel, and the wiring that connects the generator to the home's electrical system. The transfer switch is what keeps the generator from back-feeding the utility line, and it is the piece that has to be done correctly. We handle the full electrical hookup and confirm the panel is set up to carry the generator load.
A thunderstorm that knocks out power for an hour can also send a voltage spike through the line on the way out. That spike travels through every circuit in the house and into every device connected to an outlet. A whole-home surge protector installs at the panel and catches that spike before it reaches the wiring. It protects appliances, electronics, and the wiring itself from the kind of grid fluctuations that happen during Missouri storm season and from utility switching events that occur without warning.
A Level 2 home EV charger runs on a 240-volt dedicated circuit, the same voltage as a dryer or range. The installation involves running that circuit from the panel to the garage or parking area, confirming the panel has the capacity to carry the added load, and installing the charger outlet or hardwired connection. If the panel is already close to capacity, we give you a plain answer on repair versus upgrade before any work is scheduled. That way the job is scoped correctly from the start.
An electrical inspection covers the panel, the branch circuits, the outlets, the grounding system, and the visible wiring throughout the home. Buyers and sellers use them to understand what a property's electrical system actually looks like before a transaction closes. Older homes in Arnold benefit from an inspection before or after a renovation, when new work connects to existing wiring of unknown condition. We also handle hardwired smoke detector installation and carbon monoxide detector wiring as part of this work.
You get the price on the phone before anything is scheduled. The scope is confirmed before work begins, and you get a straight answer on what the job covers and what it costs. Whether it is a ceiling fan installation, an outlet replacement, an EV charger circuit, or a full panel upgrade, the pricing conversation happens first.
Real answers. Real pricing. Real fast response.
We're ready to get your circuits working again.
A flickering light and a full rewire start the same way: a call, a scope, and a clear answer on what the job involves. Homeowners call about repairs, panel upgrades, outlet and lighting work, and wiring for additions. Landlords and property managers need reliable electrical work completed on schedule so a unit is ready to rent. Commercial clients, including offices, retail spaces, and light industrial properties, need the same quality of work with an understanding of what a business interruption costs. We handle both sides, and the approach is the same either way: confirm the scope, confirm the price, do the work correctly.
Arnold is our primary service area, and we work throughout Jefferson County on a regular basis. That includes Barnhart, Imperial, Herculaneum, Festus, Crystal City, and Pevely. If your property is in the area and you need electrical work handled, call and we will confirm we can get to you.
We cover the full range of residential and commercial electrical work in Arnold and throughout Jefferson County. That includes repairs and troubleshooting, breaker panel replacements and service upgrades, outlet and switch installation, lighting, ceiling fans, wiring and rewiring, dedicated circuits, EV charger installation, backup generator hookups, whole-home surge protection, and electrical safety inspections.
If you are not sure whether your job fits, call (636) 746-4995 and we will tell you on the call.
When you call, the job gets scoped on the phone. You describe what you are seeing or what you need done, and we work through what the visit will involve and what it will cost before anything is scheduled. Once the scope and price are confirmed, the appointment is set based on what is available.
The more detail you can give about the symptom or the project, the more accurate the phone quote will be. For a repair call, describe what you are seeing: flickering lights, a tripped breaker, a dead outlet, a burning smell. For an installation project, tell us what you are adding and where. Panel work and rewiring may need a follow-up assessment on-site before the full scope is confirmed, but the call is where that process starts.
The price is confirmed before any work begins. If a diagnostic visit uncovers something beyond the original scope, that gets explained and priced before anything additional is done. You are not asked to approve work you have not been quoted for.
Do not use the outlet or the circuit. If the panel is involved and you can safely do so, turn off the main breaker.
Call us at (636) 746-4995 right away.
We take short-notice calls every day from 8:30 AM to 8:00 PM, and a real person will answer and help you figure out the next step.

Electrical work covers a wide range of jobs, and knowing what each service involves helps you call with confidence. The table below lays out what we handle, who each service fits best, and a practical note to keep in mind.
Call (636) 746-4995 to talk through what you are seeing and get a price before anything is scheduled.
| Service | What's Included | When You Need It | What to Keep in Mind |
|---|---|---|---|
| Backup Generator Installation | Transfer switch installation, Generator-to-panel wiring, Portable and standby hookup, Grid isolation for safe operation | Arnold homes that lose power during storms and ice events | A generator wired without a proper transfer switch is a hazard to utility workers restoring power. The transfer switch is not optional. |
| Dedicated Appliance Circuits | 240-volt outlet installation, Single-circuit runs for major appliances, Panel capacity check, Dryer, range, and refrigerator circuits | Anyone adding a high-draw appliance that cannot safely share a circuit | Adding a dedicated circuit sometimes surfaces a panel capacity question. We confirm whether the panel has room before scheduling the circuit work. |
| Outlet & Switch Installation | Grounded three-prong outlets, GFCI outlets in wet areas, Dimmer and three-way switches, USB outlet installation | Homeowners replacing two-prong outlets or adding convenience receptacles | Two-prong ungrounded outlets in an older home often point to a broader wiring picture worth having assessed while the work is already open. |
| Basement & Sump-Pump Circuits | Dedicated sump-pump circuit, Basement outlet installation, GFCI protection in wet areas, Circuit capacity for finished basement loads | Homeowners finishing a basement or protecting against flooding with a dedicated sump circuit | A sump pump that shares a circuit with other loads can lose power at the worst moment. A dedicated circuit removes that risk. |
| Ceiling Fan Installation | New fan installation, Fan and light kit wiring, Box upgrade for fan-rated support, Replacement of existing fans | Rooms that need both light and airflow, or where an existing fan has failed | If the ceiling box is not rated to support a fan's weight and movement, we replace it as part of the installation rather than leaving it as a risk. |
| Older-Home Rewiring | Knob-and-tube replacement, Aluminum branch-circuit remediation, Partial or full rewire, Grounding and bonding updates | Owners of older Arnold homes with original or outdated wiring materials | Aluminum branch-circuit wiring requires specific connection methods at every device. A standard outlet replacement is not enough to address the risk. |
| EV Charger Installation | Level 2 charger circuit, 240-volt dedicated run, Panel capacity check, Garage or driveway outlet or hardwired connection | EV owners who want faster home charging than a standard outlet provides | We check panel capacity before scheduling the circuit run. If the panel needs room first, that conversation happens up front rather than on the day of installation. |
| Electrical Safety Inspections | Panel and wiring review, Outlet and grounding check, GFCI and AFCI assessment, Written findings summary | Home buyers, landlords, and anyone unsure of the condition of their wiring | An inspection is the right starting point when the wiring history is unknown. It gives you a clear picture before you commit to a repair or purchase. |
| Electrical Repairs & Troubleshooting | Fault diagnosis, Dead outlets and breakers, GFCI and AFCI issues, Burning smell or warm cover plates | Any home or business with an unexplained electrical symptom | The fault is traced before anything is replaced, so the scope stays honest and you know exactly what you are paying to fix. |
| Whole-Home Surge Protection | Panel-mounted surge device, Full-house circuit coverage, Protection from lightning and utility switching, Appliance and electronics protection | Homeowners with sensitive electronics or who lose equipment during Missouri storm season | A power strip covers only the devices plugged into it. A panel-mounted device catches voltage spikes before they reach any circuit in the house. |
| Electrical Panel & Service UpgradesMost Popular | Load calculation, Panel replacement, Service-entrance work, Circuit adjustments to current code | Older homes adding EV chargers, appliances, or home office loads | A panel upgrade is often required before a home can be sold or before an insurance carrier will renew a policy on older wiring. |
| Lighting Installation | Recessed and LED fixtures, Dimmer-compatible lighting, Outdoor and security lighting, Under-cabinet and landscape lighting | Homeowners upgrading interior lighting or adding exterior security lighting | Outdoor fixtures in Missouri need weatherproof-rated housings. We confirm the right rating for the location before anything goes in. |
| Breaker & Fuse Repair | Breaker that trips or won't reset, Fuse box assessment, Breaker replacement, Panel interior inspection | Homes where a circuit keeps going out under normal loads | A breaker that trips repeatedly under normal use is telling you something. Resetting it without diagnosing the cause does not fix the underlying problem. |
| Wiring & Circuit Installation | New circuit runs, Wiring for additions and remodels, Circuit mapping, Code-compliant rough-in and finish wiring | Remodels, additions, or any project that needs new circuits run from the panel | Wiring inside finished walls takes more time than open-stud work. We scope the access situation on the call so the job is planned correctly before we arrive. |
