Our New Berlin Electrical Services
Mr. Holland’s diagnoses comfort problems, repairs failing equipment, performs seasonal maintenance, and replaces unreliable or inefficient systems. For new installations, we consider the property’s layout, insulation, ductwork, fuel source, electrical capacity, and year-round heating and cooling demand.
Electrical Repair
A dead outlet, warm switch, flickering fixture, or circuit that repeatedly shuts off may have a problem behind the visible component. We test the affected wiring and devices to find the source, then complete the repair needed to restore safe, reliable operation.
Electrical Installation, Replacement & Rewiring
New appliances, remodeling projects, and aging wiring can all require changes to the electrical system. Mr. Holland’s installs and replaces circuits, outlets, switches, wiring, and other components. Depending on the condition of your property, the work might involve one problem area, part of the building, or a complete rewiring project.
Electrical Panels
Your electrical panel has to distribute power safely while supporting the total demand placed on the property. Our electricians repair damaged panel components, replace older fuse boxes, and install panel upgrades when more capacity or circuit space is needed. We calculate the electrical load before recommending a replacement.
EV Chargers
A dedicated home charger makes daily EV charging faster and more convenient than relying on a standard outlet. We check the panel, calculate the available capacity, plan the cable route, and install the correct circuit for the selected charger. If an upgrade is necessary, you’ll know before we start the project.
Lighting Installation
The right lighting can improve visibility, security, and how a room functions. We install recessed, indoor, outdoor, landscape, security, and other lighting systems for New Berlin properties. Our electricians can also replace outdated fixtures or correct wiring and control problems affecting existing lights.
Generators
A standby generator can keep heating, refrigeration, lighting, sump pumps, and other important equipment running during an outage. Mr. Holland’s installs, repairs, and maintains Generac generators for homes and businesses. As a Generac Power Pro Premier Dealer, we can help size the unit and complete the required electrical connections.
Electrical Maintenance & Safety Inspections
An inspection can identify loose connections, damaged wiring, improper repairs, overloaded circuits, and outdated components before they lead to a larger problem. We also test panels, outlets, switches, GFCI protection, and other accessible parts of the system. Maintenance is especially useful when buying an older property, planning a remodel, or adding major equipment.
Commercial Electrical
New Berlin businesses rely on dependable power for lighting, equipment, technology, security systems, and daily operations. Our commercial electricians provide troubleshooting, repair, circuit installation, panel work, lighting upgrades, and other electrical services. We can address an active problem or plan work around an upcoming renovation or equipment change.
24/7 Emergency Electrical
Call us right away if you notice sparks, a burning odor, hot or discolored outlets, buzzing from the panel, exposed live wiring, or a sudden partial power loss. Mr. Holland’s provides 24/7 emergency electrical service in New Berlin for homes and businesses. Avoid touching the affected equipment, and call 911 first if you see smoke or fire.

A+ for Everything!
Could not ask for a better business to work with. From replacing my sewer stack to inevitably having to replace my main sewer line, they gave 100%. Took their time to explain each step and did the job correctly. And to make them even better, they came out.
Mr. Holland’s is It!
Our AC took a dive on the hottest week of the summer. They were able to get in after a few days and have a whole new system installed and running perfectly! With our old system being from 95’, it was time we invested.
Highly Recommend
The technician who came to service my home was Shannon, and he was absolutely the best. I wish I could give him a million stars. He knew exactly what to do with minimum effort. If I have any issues again in the future, I’m definitely going to request him.
Knowledgeable & Straightforward
Mr. Holland’s laid out the options for our boiler, which is 25 years old. Left everything in good order and was very pleasant. Couldn’t be happier!
Absolutely 5 Stars – I’d Give Them 10 If I Could
Kyle came out yesterday to fix our air conditioner, and he was a godsend! It’s blistering hot and humid today. Turned out to be a fried wire in the control panel. We’re cool & so comfortable today, and the bill was exceptionally reasonable.
Great Work Paul, and Thank You Mr Hollands!
Mr Hollands came through in a pinch, and we couldn’t be more pleased with the prompt scheduling and service by our technician, Paul Johnson. This is our first experience with Mr Hollands, and they’ve definitely earned our business in the future.
Electrical Problems To Look Out For in New Berlin
Electrical problems don’t always cause an immediate outage. Watch for changes in how outlets, switches, lights, and breakers behave, particularly when several warning signs appear at once.
Outlet & Switch Issues
An outlet or switch should not feel hot, buzz, spark during normal use, or show dark marks around its faceplate. Loose plugs, intermittent power, and outlets that stop working may also indicate a worn device or damaged connection. Stop using the affected component until an electrician can examine it.
Panel & Breaker Issues
A breaker that trips once may be responding to a temporary overload, but repeated trips need to be investigated. Buzzing, corrosion, heat, burning odors, or melted components around the panels require prompt attention. Continually resetting a breaker without finding the cause can leave an unsafe condition unresolved.
General Electrical Warning Signs
Flickering lights throughout the property, mild shocks from appliances, unexplained power changes, exposed wiring, and frequent bulb failures may point to a broader electrical issue. Some problems involve one device, but others originate in a circuit, panel, grounding system, or service connection. An inspection can determine how far the issue extends.
Electrical Permit Requirements in New Berlin
Yes, most electrical work in New Berlin requires a permit and inspection, including new circuit installations, electrical panel upgrades, standby generator installation, EV charger installation, and major electrical remodeling. Homeowners are not allowed to do their own major electrical work. Hiring a licensed electrician in New Berlin ensures that all permitting is correct and the electrical work is done right.

Common Electrical Questions
What electrical problems require emergency service?
Call as soon as possible for sparks, burning odors, hot outlets, buzzing or overheating at the panel, exposed live wiring, or a sudden loss of power affecting only part of the property. If there is smoke or fire, leave the building and call 911.
Can an older home support modern electrical equipment?
It depends on the condition of the wiring, panel capacity, available circuit space, and the demand created by the new equipment. An electrician can inspect the system and calculate the load before recommending a dedicated circuit, panel upgrade, rewiring, or no additional work.
Will I need a panel upgrade for an EV charger?
Not every EV charger requires a new electrical panel. We compare the charger requirements with the property’s existing load, panel rating, and available breaker space. If the current system can’t support the charger safely, we’ll review the necessary upgrade before installation.
