The electrical demands on a home have changed faster than most wiring has. What used to power a few circuits for lights and a refrigerator now has to carry EV chargers, home offices, electric ranges, and central air conditioning, often through a panel that was sized for none of it. That gap between what a house was built for and what it is being asked to do is behind a large share of the calls we get in Oakville.
We handle the full range of residential and commercial electrical work in Oakville and the surrounding area. Homeowners dealing with a tripping breaker or a panel running out of room, landlords getting a unit ready between tenants, and contractors who need an electrician on a renovation schedule all reach us the same way: a call, a conversation about the scope, and a price before anything is booked. We are available every day from 8:30 AM to 8:00 PM.
A 100-amp service panel made sense when it was installed. It does not make as much sense when the same home now has two refrigerators, a washer and dryer, a dishwasher, an electric range, and a Level 2 EV charger in the garage. The panel was not designed for that load, and the signs show up as breakers that trip under normal use, circuits that cannot support what is plugged into them, or a panel with no room left for additional breakers.
Panel upgrades and service-entrance work make up a significant part of what we do in Oakville. That includes replacing the panel itself, upgrading the service from 100 to 200 amps where the home needs it, and adding a subpanel when a detached structure or a finished basement needs its own feed. The scope and price are confirmed on the call before any visit is scheduled.
Renovation work has a sequence, and the electrical rough-in has to happen before drywall goes up, not after. When the order is reversed, the result is walls that have to be opened again, extra time on the job, and a finish that shows the repair even after it heals. We coordinate with general contractors and other trades to make sure the circuits, boxes, and rough wiring are in place before the project moves to the next stage.
Extensions and additions follow the same logic. If the new space needs dedicated circuits, new lighting positions, or a subpanel of its own, those decisions need to happen at the planning stage, not when the framing is already done. Getting the electrical scope confirmed early means the rest of the project runs on schedule rather than waiting on us.
Commercial build-outs in Oakville typically require a clear electrical plan before fit-out begins. New circuits for equipment, upgraded service to handle the load, and lighting positioned to the finished layout all need to be roughed in at the right point. We work around business hours and tenant schedules where the space is already occupied, and we confirm the scope before any work starts so the build-out does not stall waiting on the electrical.
An inspection gives you a documented picture of what the system contains and what it does not. Buyers use them before closing on an older home. Landlords use them before a tenancy starts or when a unit has not been inspected in years. The inspection covers the panel, visible wiring, outlets, grounding, and bonding, and the report names what is there and what needs attention.
A panel where half the breakers are labeled "misc" or not labeled at all is a real problem when something trips or when new work is being planned. We map the circuits, confirm what each breaker controls, and label the panel accurately. That work pays for itself the first time a fault needs to be traced quickly.
An electric range, a chest freezer, a dishwasher, or a dryer each draws enough current that sharing a circuit with other loads leads to nuisance tripping and, over time, a genuine hazard. A dedicated circuit runs from the panel to a single appliance or outlet with nothing else on the line. We size the circuit to the load and confirm the panel has room before any work is scheduled.
Running power to a detached structure is a project that involves its own set of decisions: whether the run goes underground or overhead, what the structure needs to carry, and whether it needs its own subpanel or a simple circuit feed. Electric gates and driveway lighting follow the same logic. We assess the run and the load, then confirm the scope before the work starts.
Dead outlets, outlets that feel warm, switches that spark, and two-prong ungrounded receptacles are all situations that call for a replacement rather than a reset. GFCI outlets in kitchens, bathrooms, and exterior locations are required by current code and protect against shock in wet areas. Arc-fault and ground-fault breakers address a different set of risks at the panel level. We handle the installation and confirm the circuit is correct before the visit is done.
Grounding and bonding problems often surface during an inspection or when a new appliance is installed and something does not behave as expected. A system that is not properly grounded creates a path for fault current that can damage equipment or create a shock hazard. We trace the grounding system, identify what is missing or incorrect, and make the corrections to current standards. Code-compliant wiring on every job means the fix holds up, not just for now.
Not every electrical problem in a home originates inside the home. The utility owns the service entrance up to the meter, and faults on that side of the line are their responsibility to repair. The symptoms can look similar from inside the house: partial power loss, flickering across multiple circuits, or voltage that is low or inconsistent.
We start by determining where the fault actually lives. If the problem traces back to the meter base, the service entrance, or the utility's equipment, we tell you that clearly and explain what the next step looks like on their end. If it is on our side, we proceed with the repair. A plain answer on where the fault sits is part of what the diagnostic visit covers, and that answer comes before any work is done.
A price is not something we can give without understanding the scope, and the scope depends on what the fault turns out to be, what has to be opened or accessed to reach it, and whether the existing panel or circuit can carry what is being added or changed. Those are the things that move a quote. A ceiling fan installation in a room with a proper switched box is a different job from the same installation in a room where the wiring has to be run and a fan-rated box installed first.
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. The price is confirmed before anything is scheduled. If a visit uncovers something beyond the original scope, that gets explained and priced before any additional work is done. You get a straight answer on what the job covers and what it costs. Local means we care what the neighbors think, and that starts with the pricing conversation.
Recessed lighting changes how a room reads without adding bulk. It also gives more flexibility in where furniture sits and how the light falls across the space. 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. Dimmer-compatible fixtures and switches are worth doing at the same time as new lighting, since the wiring is already accessible.
Ceiling fan installation comes up regularly, and the most common complication is a ceiling box that is not rated to carry a fan's weight and movement. We check the box before the fan goes up and replace it if it is not rated. That is a detail that matters for the fixture and for the ceiling around it.
Exterior lighting covers a range of needs: a motion-sensor floodlight at a garage door, landscape lighting along a path, weatherproof outlets for seasonal use, or security lighting at entry points. All of it needs to be weatherproofed and wired correctly, because exterior electrical work is harder to revisit once it is buried or enclosed. We handle the wiring and the fixture installation and make sure everything is connected to a properly protected circuit. Homeowners in Oakville often read our full list of electrical services before getting in touch.
Getting an appointment set should not require rearranging your day around a vague window. When you call, the scope is confirmed on the phone and the appointment is set based on what is available. You know what the visit covers and what it costs before anyone shows up.
For problems that will not keep, we take short-notice calls every day from 8:30 AM to 8:00 PM. A sparking outlet, a panel that smells like it is burning, or a breaker that will not reset are not situations to sit on. Call and describe what you are seeing, and we will work out the fastest path to getting someone out.
For tenants and businesses that need to stay open, we confirm the scope and the timing on the call so the visit is planned around the space rather than around our convenience. That applies to landlords scheduling between tenants, offices that cannot shut down a circuit mid-day, and retail spaces where the work needs to happen outside business hours.
We serve Oakville and the surrounding communities throughout St. Louis County. That includes Mehlville, Concord, Green Park, Columbia, and Arnold, along with the broader area nearby. If your property is in the area and you need electrical work handled, call and we will confirm we can get to you.
Panel upgrades, dedicated circuits for appliances and EV chargers, outlet and switch replacements, and outdoor lighting are among the most common requests. Safety inspections also come up regularly, particularly when a home is changing hands or when a landlord is preparing a unit. The specifics vary by property, and the call is where we figure out what the job actually involves.
Yes. We handle the wiring from the main panel to a detached garage, workshop, or outbuilding, including any underground run required to get the cable there safely. The work typically includes a subpanel in the outbuilding and the circuits needed for whatever the space will be used for.
Call (636) 746-4995 and we will scope what the run involves.
We handle the electrical supply to the unit: the dedicated circuit, the disconnect, and any panel work needed to carry the added load. The installation and service of the heating or cooling equipment itself is a separate trade. If a new unit is going in and the panel does not have capacity for the circuit it needs, that is part of the conversation before any work is scheduled.
We check the most probable causes based on the symptom you described, test the circuit, and inspect connections at the relevant fixtures, outlets, and panel. If nothing shows up under those conditions, we walk you through what was checked and what to watch for so you can give us more detail if the fault recurs.
Call (636) 746-4995 and we will figure out the right next step.
It does. Older homes often have branch-circuit wiring that connects to a new panel differently than modern copper wiring does. Aluminum branch-circuit wiring, in particular, requires specific connectors and terminations that are rated for it. We assess what is there during the scoping conversation and factor it into the job before the panel work begins.
If the panel is in a common area, a shared utility closet, or a space that requires access from another party, that needs to be arranged before the visit. We confirm access requirements on the call when the job is scoped, so there are no delays when the appointment happens.
Outlets, switches, and fixtures can fail independently of the wiring that feeds them. When a fitting fails, replacing it is usually straightforward. We confirm the wiring behind it is in good condition as part of the visit, so the replacement is not just covering a deeper problem.
We tell you clearly that the fault is on the utility's side and explain what that means for your next step. That typically involves contacting the utility directly to report the issue. We can describe what we found during the diagnostic so you have something specific to pass along. We do not charge for work that was not ours to perform.
Changes to the utility's service entrance, the meter, or the incoming lines are coordinated with the utility company directly. We handle the work on the property side of the meter, including the service entrance panel and any wiring that connects to it. If the utility needs to be involved, we tell you who to call and what to ask for.
