Most people assume a loose outlet or a switch that stopped working is a handyman job. Often it is not. Behind that outlet there may be a wiring fault, a failed connection, or a circuit that has been drawing more than it was designed for. Getting it right means tracing the problem to its actual source, not just swapping the cover plate and hoping. That is where an electrician belongs, and that is exactly the kind of call we handle in Napa.
We handle the full range of residential and commercial electrical work throughout the city, from quick outlet and switch repairs to panel replacements, whole-home rewiring, EV charger installation, and everything in between. Rental property owners, businesses operating out of older buildings, and homeowners dealing with wiring that has not been touched in decades all call us for the same reason: the job needs to be done to code and it needs to stay done.

When a renovation or addition is being planned, the order in which trades come through matters more than most people expect. Electrical rough-in has to happen after framing is complete but before drywall goes up. If an electrician is not on the schedule at the right point, the walls close and the wiring has to be fished through finished surfaces, which takes longer, costs more, and leaves more disruption behind.
The same problem shows up on commercial build-outs. A new tenant space needs circuits run for lighting, data, and equipment before the ceiling tiles go in and the millwork is installed. When the electrical work is planned as part of the project rather than added at the end, the whole job runs cleaner.
We coordinate directly with general contractors, project managers, and property owners to make sure the electrical side lands at the right point in the sequence. If you are planning a build-out or a remodel in Napa and want to talk through the timing, call before the drywall is scheduled and we can work out what the visit needs to cover.
Napa's housing stock covers a wide range, from older homes in established neighborhoods where the wiring has not been updated in decades, to newer construction built to current standards. Commercial properties in the city include everything from small retail spaces to hospitality buildings that carry heavy electrical loads. The jobs below reflect what actually comes up here.
A service upgrade to a higher amperage is one of the most common calls we get from homeowners who are adding an EV charger, a hot tub, or a larger appliance and find the existing panel cannot carry the load. An older 100-amp service was built for a different time. Upgrading to 200 amps gives the panel room to carry modern demands without pushing the service to its limit. We scope the panel capacity on the call before the visit is scheduled.
Smart switch and dimmer installation is straightforward when the existing wiring has a neutral conductor in the box. Older homes often do not, and that changes what switch will work and how the installation is approached. Three-way and multi-location switching adds another layer: wiring a stairwell or a hallway so the light can be controlled from both ends requires the right switch pairing and the right traveler wiring between them. We work through the existing wiring before recommending a product or a method.
A surge protection device installed at the panel protects every circuit in the home at once. Point-of-use strips protect what is plugged into them and nothing else. During wildfire season, public safety power shutoffs followed by grid restoration can send voltage spikes through the system that damage sensitive electronics, solar inverters, and EV charger equipment over time. A panel-level device intercepts that before it reaches anything downstream. The installation is a single visit and the coverage is whole-home from that point forward.
Napa has properties where knob-and-tube wiring is still in place, either as the original system or in sections that were never updated during later renovations. Knob-and-tube carries no ground conductor and was not designed for the loads a modern household puts on a circuit. It also cannot be safely covered with insulation, which creates a problem in attics that have been updated for energy efficiency. Replacement means running new wiring to current standards, including proper grounding and bonding throughout. Arc-fault and ground-fault breakers are part of the updated system where code requires them.
The price for a job is arrived at by understanding what the work actually involves. What the fault turns out to be, what has to be opened up to reach it, and whether the existing circuit or panel can carry the change are the things that move a quote in either direction. A simple outlet replacement and a partial rewire through finished walls are different scopes, and they are priced differently for that reason.
When you call, describe what you are seeing. A breaker that trips under normal load, a section of the house with no power, a panel that feels warm, or a switch that stopped working all point somewhere specific, and a clear description on the call helps us scope the work accurately before anyone shows up. The price is confirmed before the visit is scheduled, and what it covers is explained on the same call. A plain answer on repair versus upgrade is part of every panel conversation.
We're one phone call from getting your power right.
Where the Panel Sits
In many Napa properties the main panel is in a garage, a utility room, or a basement. In older homes it may be in a hallway or a closet that was never designed for easy access. A panel that is blocked by stored items, a water heater that was installed directly in front of it, or a door that only opens partway adds time to every job that requires panel work.
Clearing a path to the panel before the visit starts is one of the most practical things a homeowner or property manager can do. It does not need to be empty, just accessible. The same applies to the area where the work is being done: knowing in advance whether an outlet is behind a piece of built-in furniture, or whether a circuit runs through a finished wall, helps us plan the visit and tell you what to expect. Clear communication from the first call to the final test is how the work runs here.
Older Homes and the Wiring They Hide
Napa has a share of older homes with high ceilings, finished attics, and crawl spaces that were not designed with future electrical access in mind. Running a new circuit through a finished ceiling, adding a ceiling fan where no wiring box exists, or replacing wiring in a crawl space that has not been accessed in years all require more planning than a straightforward outlet swap.
We talk through access on the call before the visit, so the scope is understood in advance. If reaching the work requires going into a tight crawl space or working above a high ceiling, that changes what the visit involves and how long it takes. Knowing that ahead of time means the job is planned correctly rather than discovered on site.
The work area left as it was found is a standard we hold on every job. Where access through a wall or ceiling is needed, we discuss what that involves before anything is opened up.
Availability and Timing
Appointments are arranged on the call. We are available every day from 7:00 AM to 8:30 PM, which covers early-morning calls before a workday starts and evening calls when something goes wrong after hours. For problems that will not keep, such as a sparking outlet, a burning smell near the panel, or a breaker that will not hold a reset, call as soon as you notice it and we will confirm what the schedule allows.
For tenants and businesses that need to stay open during the work, we talk through the timing on the call. A circuit that needs to be de-energized during business hours is a different planning problem than a weekend repair in an empty unit. We work around what the property and the people in it actually need.
You know who to call if you ever need us again. Call now. Get it scoped. Get it wired to code.
Napa is our primary service area in the county. We also take calls from Yountville, American Canyon, Sonoma, Green Valley, and Silverado Resort. Work extends across Napa County, and most calls from the surrounding area are covered. For what the job actually entails, our list of electrical services lays it out.

Older wiring, including knob-and-tube systems and aluminum branch circuit wiring, requires a different approach than standard modern wiring. We assess what is in place before recommending a scope of work, and we explain what we find before any repair or replacement is scheduled. Where a partial or full rewire is the right call, we walk through what that involves and price it before anything starts.
In many cases, yes. If the work involves circuits that do not supply the registers or payment systems, those can stay live. When the work does affect those circuits, we plan the shutdown window to minimize the impact on operations and confirm the timing with you in advance.
The starting point is the distance from the main panel and the load the outbuilding needs to carry. From there, we determine the right wire size, the method of running the supply, and whether a subpanel inside the structure makes sense for the number of circuits needed.
We check whether the problem affects the whole property or only part of it, and whether the utility's meter and service entrance show any signs of a supply issue. If the fault is on the utility side of the meter, we tell you and you contact the utility directly. If it is on the property side, we handle it.
We install standard fittings as part of the job. If you want a specific style or finish to match existing hardware, let us know on the call and we can discuss what options are available and how to approach the selection.
Older commercial buildings in Napa often carry panel and wiring systems that were designed for lighter loads than the equipment now drawing from them. Common calls include service upgrades to handle added equipment, dedicated circuit installation for kitchen and bar equipment, code violation repairs ahead of a lease renewal or inspection, and surge protection for buildings that run sensitive electronics or point-of-sale systems. We scope commercial jobs the same way we scope residential ones: on the call, before the visit is scheduled.
An intermittent fault requires testing under the conditions that trigger it, which sometimes means monitoring the circuit under load rather than just checking connections at rest. We ask detailed questions on the call about when the problem appears, because that information shapes how the visit is structured.
The electrician needs to be on site for rough-in before walls close, and again for trim-out after drywall and paint are done. If other trades are working at the same time, we coordinate the sequence with you so the work does not hold up the rest of the project.
The sooner you call, the sooner the work is scoped and on the schedule. We handle repairs, panel upgrades, EV charger installation, whole-home surge protection, rewiring, lighting, ceiling fans, dedicated circuits, and electrical safety inspections for homes and businesses throughout Napa. Phones are answered every day from 7:00 AM to 8:30 PM.

Every electrical job we handle starts with a clear scope and a price you hear before anything is scheduled. Whether the call is about a tripped breaker, a panel that can no longer carry the load, or a new EV charger circuit, we work through the same process: trace the problem, explain what it takes to fix it, and get the work done to code. The table below covers the services we offer in Napa and across Napa County, along with notes on what each one involves and who it fits best.
| Service | What the Job Involves | When You Need It | Things to Know |
|---|---|---|---|
| Electrical Panel and Service UpgradesMost Popular |
| Homes adding EV chargers, major appliances, or solar systems that have outgrown their current service | Panel capacity is the starting point for any large electrical addition. We give a plain answer on repair versus upgrade before any work is scheduled, so you know what you are approving. |
| Outlet and Switch Installation |
| Kitchens, bathrooms, garages, outdoor locations, and rooms being updated | Code requires GFCI protection in kitchens, bathrooms, garages, and outdoor areas. When we replace an outlet in those locations, protection requirements are addressed as part of the job. |
| Wiring and Circuit Installation |
| Older Napa homes near campus and downtown with original or outdated wiring | Knob-and-tube wiring has no ground conductor and cannot be safely covered with insulation. Replacement brings the affected circuits up to current standards, including proper grounding throughout. |
