Services Our Greenfield Electricians Handle
Our licensed electricians are trained for the full range of residential electrical work, from quick repairs to complete system replacements. We assess the situation honestly, explain the options clearly, and build every job to code.
Electrical Repairs
Most electrical problems have a specific, identifiable cause. We do not patch the symptom and leave. We find the source, whether that is a faulty connection, a worn outlet, or a circuit that is consistently overloaded, and we make the repair with lasting materials. Every repair is covered by our satisfaction guarantee and warranty.
Electrical Inspections
An inspection is one of the most honest things you can do for an older home. We walk through your wiring, panel, and outlets with trained eyes and tell you plainly what we find, what needs attention now, and what can wait.
Electrical Panels
A panel that was installed in the eighties was not designed to run a modern home's appliances, devices, and EV charger simultaneously. We assess your existing panel, explain the upgrade options, and install a system that handles today's load without running hot.
Electrical Wiring
Greenfield has no shortage of homes where the wiring is several decades old. We repair damaged or deteriorating wiring, reroute circuits where needed, and install new wiring runs for additions, appliances, and projects that require dedicated circuits.
Lighting Installation
We install every type of residential lighting, from recessed cans and LED retrofits to outdoor security lights, garden and uplighting, garage and work area fixtures, and ceiling fan wiring. The right lighting setup improves how a space looks, feels, and performs.
Switches & Outlets
Sparking outlets, warm switch plates, receptacles that no longer hold a plug, and switches that buzz or feel stiff are all signs that something needs to be replaced. We repair and install switches and outlets throughout your home, including GFCI installation near water, dimmer switches, and USB charging receptacles.
EV Chargers
A home Level 2 charger delivers 15 to 40 miles of range per hour, meaning most Greenfield homeowners wake up to a fully charged vehicle every morning. We install the charger and the dedicated 240-volt circuit it requires, after assessing your panel for adequate capacity.
Surge Protectors
Lightning, utility grid fluctuations, and large appliances cycling on all create voltage spikes that slowly degrade your electronics and appliances. A whole-home surge protector installed at the panel intercepts those spikes before they reach your wiring and devices.
Smoke Detectors
Wisconsin law requires smoke detectors on every floor level and near sleeping areas. We install hard-wired detectors in the locations that provide the most effective coverage and meet all state requirements.
24/7 Emergency Electrical Services in Greenfield
There are electrical situations where waiting until the next business day is simply not an option. A burning smell from a wall, visible sparks, unexpected loss of power, or a panel that keeps tripping no matter how many times you reset it all call for a professional, not a web search and a wait. Mr. Holland's keeps electricians on call 24 hours a day, dispatching from New Berlin to reach Greenfield quickly with same-day service available at any hour. Call (262) 500-3410.
Electrical Financing Options in Greenfield, WI

Mr. Holland's offers $0 down, 0% interest, and no payments for up to 12 months on approved credit, and we work with homeowners who have been turned away elsewhere.

5 Signs Your Greenfield Home Needs an Electrician
Your home's electrical system gives you signals before things go seriously wrong. The challenge is knowing which ones deserve immediate attention. These five are worth acting on now.
- Frequent circuit breaker trips: A breaker that trips repeatedly is not malfunctioning, it is doing its job. Something is consistently pushing that circuit past its safe limit, and it needs to be identified and corrected.
- Flickering or dimming lights: When your lights react visibly to an appliance starting up, that reaction is telling you there is either a loose connection somewhere in the circuit or the panel is running low on capacity.
- Burning or hot plastic smells: Any odor that suggests overheating near an outlet, switch, or your panel is a warning that should not be rationalized away. Heat in the wrong places is how electrical fires start.
- Warm or discolored outlets: A warm outlet cover or switch plate is almost always a sign of a connection problem or overloaded wiring hidden behind the wall that needs professional attention.
- Buzzing or humming from your electrical system: Electrical components should be silent. Noise from a switch, outlet, or panel usually points to arcing or a loose connection, both of which can cause real damage over time.
