Landlords and property managers in Janesville carry a different kind of electrical workload than a homeowner does. A homeowner calls when something stops working. A property manager calls because a tenant already called them, the unit needs to be back in service before the next showing, and there is no margin for a week-long wait. Hellenbrand Electric handles that kind of call. We work around occupied units, coordinate with tenants directly when that helps, and get the work done without turning a repair into a disruption.
The electrical demands of a rental portfolio in a city this size are real and varied. Older construction, units that have changed hands many times, wiring that has been added to without always being documented: these are the conditions we work in regularly. Whether you manage a handful of properties or a larger portfolio across Rock County, we handle the electrical side and keep you informed through every step.
When a problem will not keep, we make same-day service available. A tripped breaker that will not reset, an outlet that stops working in a kitchen, a lighting circuit that goes dark in a commercial space: these are not situations where a scheduled appointment three days out is useful. Call and we will tell you what is open on the schedule that day.
We also understand that some properties cannot simply shut down while work is happening. A business that needs to stay open, a tenant who cannot leave, a unit that has to stay functional: we work around those constraints. The goal is to get the electrical issue resolved without making the property's normal operation stop. Call today and we'll get the power back where it belongs.
Older properties in Janesville were wired for the loads of their era. Add a modern range, a dryer on a circuit that was never meant to carry one, or an EV charger in a garage that was wired as an afterthought, and the system is being asked to do something it was not designed to do. The first step is always a load calculation: we look at what the panel is currently carrying, what the new demand adds, and whether there is headroom to work with.
If the panel can support the added load, we run the dedicated circuit and do it right. If it cannot, the conversation shifts to what a service upgrade involves and what that unlocks. A 200-amp upgrade gives the property the capacity to carry modern loads without the panel running at its limit. We scope that work on the call and give you a clear price before anything is scheduled. Work in this area gets done to the code inspectors here actually enforce.
The price you get when you call is based on the work as described. That means the more clearly you can explain what is happening, the more accurately we can scope it before anyone shows up. We ask about the affected circuit, what the outlet or fixture is doing, whether the breaker is tripping or holding, and what, if anything, has changed recently in the property.
What changes a quote is a change in scope. If a repair call reveals a broader wiring problem, we explain what we found before any additional work begins. You are not presented with a higher number at the end without a conversation first. Electrical work done to the standard the next inspection expects is what every job delivers, and that standard does not shift depending on the size of the property or the urgency of the call.
The result that matters is a repair that holds. Getting there sometimes means dealing with parts that are no longer standard. Older panels take breakers that are harder to source. Fixtures from a previous renovation may use fittings that have been superseded. When a property has been updated in stages over the years, what is inside the walls does not always match what is on the panel schedule.
When a part has to be ordered rather than fitted the same day, we tell you that on the call or on site, not after the fact. If a same-day fix is possible with a compatible part, we use one that meets code and fits the existing installation correctly. If it is not, we explain the timeline and make sure the property is safe in the meantime. No pressure and no gimmicks, just safe, solid wiring, whether the fix takes an hour or requires a return visit.
Electrical work in a city like Janesville does not look the same from one address to the next. A call from an older home on original wiring is a different job than a call from a commercial tenant space that needs a new circuit for equipment. The section below covers the full breakdown, but the situations that come up most often fall into a few clear categories.
A fault that shows up intermittently is harder to diagnose than one that has stopped working entirely. Breakers that trip without an obvious cause, outlets that work sometimes and not others, lights that flicker on one circuit but nowhere else: these take a proper diagnostic, not a reset and a hope. We trace the fault back to its source before recommending any repair, and we explain what we found in plain terms before the work begins.
A panel that was sized for a smaller load is not going to fail dramatically. It is going to run at its limit, trip breakers under normal use, and leave no room for anything new. Replacing a panel or upgrading to a higher-capacity service is the kind of work that changes what a property can do going forward. We handle the load calculation, the panel replacement, and the service entrance work when the scope calls for it.
New circuits, outlet additions, lighting installations, ceiling fan wiring, and dedicated appliance circuits all start with a clear scope. We confirm the panel has capacity, plan the circuit path, and do the work to code. For installation work across multiple units or a commercial space, we coordinate the schedule so the property stays functional while the work is underway.
See the full service breakdown on the services page for everything we handle.
Heavy equipment draws more current than a standard circuit is rated to carry. A welder, an air compressor, or a piece of shop machinery needs a dedicated circuit sized for its actual load, with the right wire gauge and breaker to match. We run those circuits from the panel and make sure the installation is safe for continuous use under load.
A panel that is failing, outdated, or simply too small for what the property needs is a straightforward job when it is scoped correctly. We replace breaker panels, swap out failing breakers, and upgrade service capacity when the load calculation shows the existing panel cannot keep up. Every panel job includes a check of grounding and bonding throughout the affected system.
An intermittent fault is the kind of problem that does not show up on demand. We use proper test equipment to trace what is happening in the circuit rather than working from guesswork. When a breaker trips without a clear cause or an outlet behaves inconsistently, finding the actual source of the problem is the only repair that holds.
Hardwired alarms need a proper circuit connection and, in most installations, interconnection so that all units signal together. We install and replace hardwired smoke and CO detectors as standalone jobs and as part of larger renovation or rewiring projects. For rental properties, keeping these installations current and code-compliant is part of what responsible property management requires.
A panel-level surge protector covers every circuit in the building from a single installation point. It is a straightforward job that protects appliances, electronics, and the wiring itself from voltage spikes that can do real damage. We install whole-home surge protection as a standalone job or as part of a panel upgrade.
A generator that is not properly connected to a transfer switch is a safety risk, not a solution. The transfer switch isolates the home from the utility line when the generator is running, which protects both the property and anyone working on the line outside. We handle the transfer switch installation, the generator circuit, and the panel connection. In a region where multi-day outages are a real winter risk, getting this installation done correctly matters.
We cover Janesville and the surrounding communities throughout Rock County, including Milton, Hanover, Shopiere, Footville, and Fulton. Whether the property is in the city or in one of the smaller communities nearby, we take the call and get the work scheduled. Reach out and an electrician will follow up.
If you are in the area and need electrical work handled, the full picture of what we cover is on the services page. Call (608) 593-5149 and we will go over the scope and give you a rate before anything is scheduled.
Yes. We serve Janesville and the surrounding communities throughout Rock County, including Milton, Hanover, Shopiere, Footville, and Fulton. The scope of work and the scheduling process are the same regardless of which community the property is in. Call (608) 593-5149 and we will confirm coverage and get you a price on the call.
Crawl space work involves accessing the space to run or inspect wiring below the floor. Conditions vary significantly by property, and we assess access, clearance, and any moisture or insulation factors before committing to the approach. If the crawl space presents unusual conditions, we describe what we find before proceeding.
If the new appliance has a higher amperage draw than the circuit was designed for, the breaker will trip or the wiring may be undersized for the load. We check the circuit rating against the appliance specifications and either confirm the existing circuit is adequate or run a new dedicated circuit sized correctly for the new equipment.
We can review what another quote covers and explain what the work involves so you understand what you are being asked to pay for. We do not offer formal written critiques of other contractors' work, but if you have questions about whether a proposed scope makes sense, a call is a reasonable place to start.
Yes. We can provide a record of the work performed, which is useful for rental property files and future inspection reference. If a permit was pulled for the job, the inspection record also serves as documentation. Ask about this when you call and we will confirm what we provide.
Sometimes. If the panel has open breaker slots and the available capacity is sufficient, a new circuit can be added without any panel work. If the panel is full or already carrying close to its rated load, adding a circuit safely requires either a panel upgrade or a subpanel. We check both before giving you a recommendation.
In some situations, yes. A subpanel can distribute load from the main panel to a specific area, like a garage, workshop, or addition, without requiring a full main panel replacement. Whether it is the right solution depends on what the main panel can already support, which we assess before making a recommendation.
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 tell you what we checked and what we ruled out, and we schedule a follow-up to continue the diagnostic. Intermittent faults can take more than one visit to catch, and we are straightforward about that rather than guessing at a repair.
Older rental stock in Janesville tends to show up with ungrounded outlets, circuits that were added without proper documentation, panels that were never upgraded from their original capacity, and GFCI protection that is missing or no longer functioning. These are all addressable problems. When we come out for a repair call, we note what we find and explain the options before any additional work is recommended.

From a tripping breaker to a full panel upgrade, we handle the electrical work that keeps homes and businesses in Janesville running safely. The table below covers everything we do in this area, who each service fits best, and a practical note to help you know what to expect before you 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 Janesville homes with outdated wiring or homeowners doing a major renovation with walls already open | Rock 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 Rock 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 | Janesville 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 Janesville'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. |
