Something stopped working. That is how most calls start. A breaker tripped and will not reset. An outlet is dead. The lights in one room are flickering and nobody knows why. The job does not have a name yet when the phone rings, and figuring out what is actually happening is part of what we do. Hellenbrand Electric handles electrical work throughout Sun Prairie and the surrounding area, and the first thing we do on any call is listen to what is going on before we talk about what it takes to fix it.
Sun Prairie is a city with a real mix of housing. Newer construction sits alongside homes that have been added onto, rewired in pieces, or left mostly original. Businesses, rental properties, and single-family homes all generate different calls, and we handle all of them. Whether you are a homeowner dealing with something that has been bothering you for a while or a property manager who needs a unit brought up to code before a new tenant moves in, the process is the same: we come out, we find the problem, and we explain what we found before any work starts.
A dead outlet, a breaker that keeps tripping, a light switch that no longer controls the right fixture. These are the calls that make up a large part of what we handle every day. The repair itself is often straightforward once we know what caused it. Getting to that cause is the work. We test the circuit, check connections, and look at the broader picture of what the panel is carrying before we recommend anything.
GFCI and AFCI protection failures are common finds during a repair visit. An outlet that will not reset, a breaker that trips under normal load, or a circuit that behaves inconsistently often points back to protection that has failed or was never installed correctly in the first place. We address what we find, not just what was described on the call.
A panel that is undersized or aging does not announce itself clearly. It shows up as nuisance trips, as circuits that cannot carry what they need to carry, or as a load calculation that leaves no room for anything new. We handle breaker panel repair and replacement, 200-amp service upgrades, and subpanel installation for homes and commercial properties in the area.
Every panel job starts with a load calculation. That tells us what the system is carrying now and what it needs to carry going forward. If a service entrance or meter upgrade is part of what the scope requires, we handle that as well. The full breakdown of panel work and pricing lives on the services page.
Adding a circuit for a new appliance, running wiring for a lighting upgrade, or installing a ceiling fan in a room that was not wired for one: these are installation jobs that look simple on the surface and require proper planning underneath. The right wire gauge, the right breaker size, and a panel that can carry the added load all have to line up before the work begins. We confirm all of that before we start, not after.
Older homes in the Sun Prairie area sometimes carry wiring that was never meant to handle what a modern household puts on it. Whole-home rewiring replaces the system from the panel out, adds proper grounding throughout, and brings the circuits up to current code. Partial rewiring makes sense when the problem is contained to specific areas, when walls are already open for a renovation, or when a particular circuit is the source of repeated trouble.
Knob-and-tube wiring is still present in some of the older housing stock in this area. It was designed for loads that bear no resemblance to what a home draws today, and it lacks the grounding that modern circuits require. Replacing it is not an emergency in every case, but it is work that needs to be assessed by a licensed electrician and addressed on a clear timeline. We evaluate what is in place, explain what the options are, and do the replacement to the standard a current inspection requires.
Plug-in detectors are better than nothing, but hardwired alarms with battery backup are what most current codes call for in residential construction and renovation. We install interconnected hardwired smoke and carbon monoxide alarms so that when one sounds, they all sound. This is a straightforward installation that matters more than most people give it credit for.
A stairwell that needs to be controlled from both ends, a hallway where the switch placement no longer makes sense, a room where a second switch was never added. Three-way and multi-location switching solves these problems cleanly. The wiring involved is more involved than a standard single-pole switch, but the result is a system that works the way the space actually needs it to.
A new range, a dryer, a workshop with serious equipment, or a hot tub all need dedicated circuits sized for the load they draw. We run the circuit, confirm the panel has capacity, and install the right outlet or connection point for the equipment. If the panel needs attention before the circuit can be added, that conversation happens on the call, not after we arrive.
Recessed LED lighting, fixture replacement, ceiling fan installation, under-cabinet lighting, and task lighting in kitchens and work areas are all part of what we install. Lighting is one of the most visible changes you can make to a space, and it has to be wired correctly to work safely and look right. We handle the circuit, the fixture, and the connections so the installation is code-compliant from the start.
Don't let a small wiring issue turn into a fire risk, and do not put off lighting or fixture work because it seems minor. Call today and we'll get the power back where it belongs.
Managing electrical work on a property you do not live in adds a layer of coordination that a standard repair call does not have. The person who books the appointment is often not the person who needs to be home for it, and the person who gets the invoice may need documentation for their records or for a future inspection.
We work with landlords and property managers across the area on exactly this kind of job. When access needs to be arranged through a tenant, we talk through the timing on the call so the schedule works for everyone involved. If a job requires a permit, we handle that conversation up front so there are no surprises about what the process involves.
After the work is done, the documentation of what was completed, what was replaced, and what the system looks like now is something we can walk you through. Landlords who need a record for a certificate of compliance or a future inspection will have what they need. Work in this area gets done to the code inspectors here actually enforce.
Same-day electrical service is available. When something is genuinely urgent, call early and we will tell you what is open on the schedule. We are available every day from 8:00 AM to 10:00 PM, which gives a wider window than a standard business-hours operation.
For tenants in occupied properties, we work around what the space needs. A business that cannot shut down a circuit during operating hours, or a rental unit where the tenant needs the kitchen functional by evening: these are scheduling realities we plan around, not obstacles we hand back to you. Scheduling an electrician shouldn't be complicated. Call and we will find a time that works.
Older homes get asked to carry things they were never designed for. An EV charger on a 100-amp panel that is already running a modern kitchen and an electric dryer. A workshop in a garage that was wired for a single light and a couple of outlets. A hot tub on a circuit that was not designed for a continuous outdoor load.
The first step is always a load calculation. That tells us what the panel is currently handling and whether there is room for what is being added. If the panel can support the new load, we run the circuit and install the connection. If it cannot, we talk through what a service upgrade involves and what it costs before any work is scheduled. Subpanel installation is sometimes the right answer for a detached garage or a workshop that needs its own capacity without a full service upgrade at the main panel.
We stay on the electrical side of every job. Running the dedicated circuit and disconnect for a heating or cooling unit is our work. Servicing the unit itself is not. Where the two trades meet, we handle our part and are clear about where ours ends.
When you call, we ask about the work. We go over what is involved, what the job typically covers, and what would change the scope if the diagnostic finds something different from what was described. You get a rate before anything is scheduled, and you get a straight answer if you have questions about what it includes.
We do not quote a number and then show up to find reasons to add to it. If the scope changes once we are on site, that conversation happens before additional work is done. Electrical work done to the standard the next inspection expects is what every job delivers, and that is reflected in how we price it. Call (608) 593-5149 and we will go through it with you.
We serve Sun Prairie and the communities around it throughout Dane County. That includes Windsor, DeForest, Cottage Grove, Maple Bluff, and Marshall. If you are in the area and need an electrician, we are taking new customers and can get you on the schedule.
We power your home. We protect your circuits. We earn the call.
Yes. If life-sustaining or medically necessary equipment is in use, we need to know before the visit so we can plan which circuits will be de-energized and sequence the work to avoid interrupting power to that equipment. Tell us on the call and we will build that into the plan.
We coordinate access with whoever holds the keys, whether that is a property manager, a landlord, or a real estate contact. For larger projects on vacant properties, we confirm a point of contact before starting so decisions about scope changes can be made without delay.
We take care not to damage the space we are working in. For jobs that involve drilling, pulling wire, or working in finished areas, we cover surfaces in the immediate work zone. If you have specific concerns about a room or a piece of furniture, mention it when we arrive and we will account for it.
Older homes in the area generate a lot of repair calls around circuits that were never upgraded to handle modern loads, GFCI and AFCI protection that has failed or was never installed, and panels that are running at capacity. Newer construction tends to produce calls around adding circuits for EV chargers, workshop equipment, or appliances that were not part of the original build. We handle both ends of that range and everything in between.
Yes, where the scope allows it. Some projects, like a full rewire or a panel upgrade combined with new circuit work, can be broken into phases scheduled separately. We discuss what makes sense for your situation on the call and plan accordingly.
Yes. When access needs to go through a tenant, we work out the timing on the call so the appointment fits the tenant's schedule and yours. If you manage multiple units or need documentation of the work for your records, we can walk through what you need after the job is done.
We manage the permit process. Requirements vary depending on the type of work and where the property is located, and we confirm what applies to your job before scheduling. You do not need to navigate that process on your own.
We run a circuit from the main panel to the outbuilding, either overhead or underground depending on the layout and local requirements. The outbuilding typically gets its own subpanel sized for the intended use, with circuits for lighting, outlets, and any dedicated equipment loads. We confirm permit requirements before the work is scheduled.
We do. Windsor, DeForest, Cottage Grove, Maple Bluff, and Marshall are all part of the area we serve, along with Sun Prairie and the broader Dane County region. Call (608) 593-5149 and we will confirm coverage at your address and get you a price on the call.

If a job is not listed or you are not sure what you need, call us and we will talk through it.
| Service | What's Included | When You Need It | Worth Knowing |
|---|---|---|---|
| Snow-Melt System Wiring | dedicated circuit for snow-melt mats or cables, thermostat and sensor wiring, GFCI protection for outdoor heating circuits, load calculation for driveway or walkway systems | homeowners installing snow-melt systems in driveways, walkways, or entry areas to manage Wisconsin winter accumulation | Snow-melt systems draw a sustained load over long periods. We calculate the full draw, confirm panel capacity, and run a dedicated circuit so the system does not compete with other loads in the home. |
| Backup Generator Installation | transfer switch installation, generator hookup to panel, dedicated circuit wiring, load assessment for critical circuits | homeowners who need to keep heat circuits, lights, and critical loads running during Wisconsin ice storms and extended outages | The transfer switch is the critical piece. It isolates your home from the utility line when the generator is running, which protects the equipment and anyone working on the line outside. |
| Electrical Panel & Service UpgradesMost Popular | 200-amp service upgrades, subpanel installation, service entrance and meter work, load calculation and capacity planning | homes with a 100-amp panel trying to carry an EV charger, modern kitchen, and winter electrical loads at the same time | Electrical work done to the standard the local inspection process requires. Every upgrade is permit and inspection ready from the start. |
| Wiring & Rewiring | whole-home rewiring, knob-and-tube and aluminum wiring remediation, partial rewires for renovations, arc-fault and ground-fault circuit upgrades | older Sun Prairie homes with outdated wiring or homeowners doing a major renovation with walls already open | Dane County has a solid mix of mid-century homes where knob-and-tube and aluminum branch-circuit wiring are common finds. Both warrant a closer look before adding load to the system. |
| Well-Pump Circuits | dedicated well-pump circuit installation, pressure switch and disconnect wiring, panel capacity check, circuit protection for pump loads | rural and semi-rural properties in the Dane County area that rely on a well for water supply | Well pumps draw significant starting current. The circuit has to be sized correctly for the pump motor, and the panel needs capacity to carry it without affecting other loads. |
| Whole-Home Surge Protection | panel-level surge device installation, protection for appliances and electronics, coordination with outlet and lighting projects | homeowners with sensitive electronics, smart-home equipment, or high-value appliances | A single surge can damage wiring and appliances throughout the home. Panel-level protection covers the whole system rather than just the devices plugged into a power strip. |
| Garage & Block-Heater Circuits | dedicated 120V or 240V garage circuits, block-heater outlet installation, GFCI protection in garage locations, subpanel for detached garages | Wisconsin homeowners who need a reliable outlet for an engine block heater or a properly wired garage workspace | A block-heater outlet needs a GFCI-protected circuit in a location that holds up to cold and moisture. We size the circuit for the load and confirm the panel has room before running the wire. |
| Breaker & Fuse Repair | breaker replacement, fuse panel assessment, circuit fault diagnosis, overcurrent protection checks | homes with breakers that trip repeatedly or a fuse box that has not been updated | A breaker that trips without a clear cause is a diagnostic signal, not just an inconvenience. We find out why before recommending any replacement. |
| Heat Tape Installation | dedicated circuit for heat tape, GFCI-protected outlet installation, load calculation for existing circuits, code-compliant wiring for roof and pipe applications | Sun Prairie homeowners managing frozen pipe risk or roof ice dams through Wisconsin winters | Heat tape needs a properly rated circuit and a GFCI-protected outlet in the right location. The electrical side has to be correct for the system to work safely through the coldest stretches of the season. |
| Electrical Safety Inspections | panel and wiring condition review, grounding and bonding check, GFCI and AFCI protection assessment, pre-purchase inspection | home buyers, landlords, and anyone who wants to know the condition of an older system | Pre-purchase inspections are especially useful in Sun Prairie's older neighborhoods, where the wiring may not have been touched in decades. |
| Electrical Repairs & Troubleshooting | dead outlets and switches, flickering or dimming lights, tripping breakers, GFCI and AFCI faults | any home or business with an unexplained electrical problem | A proper diagnostic traces the fault to its source rather than just resetting a breaker. Most repairs are straightforward once the cause is found. |
| Dedicated Appliance Circuits | dryer and range circuits, refrigerator and dishwasher circuits, workshop and garage circuits, load calculation before installation | anyone adding a major appliance or converting to electric cooking or laundry | A dedicated circuit keeps a high-draw appliance from overloading a shared circuit. We run the load calculation first so the panel can carry it safely. |
| Ceiling Fan Installation | fan and fixture wiring, switch and dimmer hookup, brace and box installation, replacement of existing fans | homeowners adding or replacing ceiling fans in any room | Older fan boxes are often not rated for the weight of a modern fan. We confirm the box and brace are correct before the fan goes up. |
| Lighting Installation | recessed and LED lighting, security and landscape lighting, outdoor weatherproof fixtures, circuit planning for new fixtures | remodels, exterior upgrades, and homes switching from older bulb types to LED | Outdoor lighting in Wisconsin needs weatherproof installation and the right circuit protection to hold up through freeze-thaw cycles and ice storms. |
| Outlet & Switch Installation | outlet replacement and addition, GFCI and AFCI outlets, dimmer and switch installation, USB and specialty outlets | homeowners adding outlets, updating older devices, or upgrading to GFCI protection in kitchens, baths, and outdoor areas | GFCI protection is required by code in wet and outdoor locations. If your kitchen or bathroom still has standard outlets, an upgrade brings the circuit into compliance. |
