Commercial Electrical & Plumbing Service in New Berlin, WI

24/7 Commercial Support for New Berlin Businesses

New Berlin runs on commercial property. The industrial park on South Moorland Road is full of manufacturers, machine shops, and distribution areas. Offices and storefronts line National Avenue and Greenfield Avenue. New commercial development is ongoing along the Moorland Road corridor by I-43. This adds more offices, industrial facilities, and commercial properties to the area. Every one of those buildings runs on electrical and plumbing systems. Those systems have to meet Wisconsin code. They also have to survive a Waukesha County winter and stay online while your crew works.

Roman Electric has served southeastern Wisconsin for almost 100 years. Our certified commercial technicians cover the full scope in New Berlin. This covers service and panel upgrades, code-compliant repairs, yearly backflow testing, and gas piping. It also includes low-voltage data and security systems, plus commercial plumbing from rough-in to final inspection. We coordinate with facility managers, general contractors, and building owners. We schedule around your production hours instead of ours.

Nearly 100 Years of Commercial Electrical & Plumbing Experience

Roman Electric is a family-owned contractor that has worked in southeastern Wisconsin for close to 100 years. Four generations have held the same standards in place. Safe installs, code-compliant systems, and straight answers for the people paying the bill. New Berlin sits inside the Waukesha County corridor our crews cover, and the drive from our shop is a short one.

In the trades, that level of continuity is uncommon. You see it in how we scope a project, how we price it, and how we answer the phone two years after the final inspection clears.

What We Handle

Our work in the city covers both trades end to end. The range runs from ground-up construction and design-build packages to preventive maintenance and emergency response. It also takes in specialty work like structured cabling and life safety systems. Every service line is staffed by licensed techs who hold current Wisconsin DSPS credentials. They spend their weeks on commercial jobs across Waukesha and Milwaukee counties.

Ground-Up Builds and Major Renovations

On new builds and major remodels, our team owns the electrical scope from design through closeout. We model and prefabricate early, so problems show up on paper instead of in the field. From feasibility through punch list, we stay in step with architects, GCs, and the other trades on site.

Repairs, Maintenance, and After-Hours Calls

New Berlin property owners and managers call us for fast repairs and planned maintenance that catches failures early. We also cover emergencies at any hour. Aging switchgear, nuisance breaker trips, a dark parking lot: we find the cause instead of swapping parts and hoping.

Low-Voltage, Data, and Building Security

A modern commercial facility needs more than power and water. Roman Electric installs and maintains the low-voltage backbone that keeps a building connected, monitored, and secure. The same contractor handles your power distribution. That means the low-voltage rough-in gets planned early instead of squeezed in at the end.

Plumbing, From Backflow Tests to Well Pumps

Our licensed commercial plumbers cover New Berlin properties on city water and private wells alike. The work runs from annual backflow preventer testing to complete mechanical installs. We check every job against Wisconsin plumbing code before we call it finished. We also sequence around the other trades so nobody loses a day.

Why Facility Managers Trust Roman Electric

Nearly a hundred years of Wisconsin commercial work is not a marketing line. It is the reason a facility manager calls us at two in the morning, then calls again for the next expansion. This history spans decades. It includes building types, equipment, and code cycles in Milwaukee and Waukesha counties. This approach manifests as fewer mid-project surprises and cleaner inspections. You also see it in systems that hold up under real commercial load.

We pair that background with current practice. Our techs keep their Wisconsin DSPS credentials active and train on updated safety standards. Every crew follows procedures built from decades of field work. Your project manager hears from us at each stage, and the number on the estimate is the number on the invoice.

Questions We Hear From New Berlin Owners

Does Roman Electric serve New Berlin, WI?

Yes. New Berlin is part of our regular southeastern Wisconsin service area. Our commercial crews work across Waukesha and Milwaukee counties. That includes nearby cities like Brookfield, Muskego, Waukesha, Greenfield, and West Allis.

What is the duration of Roman Electric's operations?

Close to 100 years. Four generations of family ownership in Wisconsin built real knowledge of local building systems and code cycles. We also know what inspectors here expect, which newer contractors rarely do.

Do you handle both commercial electrical and commercial plumbing work?

Yes. Both trades sit under one license, one project team, and one point of accountability. For a New Berlin facility manager, that means one call for a lighting retrofit and a failing water heater. When the schedule is tight, nobody blames anyone.

Do you service commercial properties on private wells in western New Berlin?

Yes. Buildings outside the city's utility service area draw from private wells. Those properties need pump service, pressure tank work, and water treatment that city-supplied buildings do not. We handle well pump maintenance and filtration alongside standard commercial plumbing.

How often does a commercial backflow preventer need to be tested?

Annually, in most cases. Wisconsin cross-connection rules call for regular testing by a certified tester. Your local water utility sets the exact schedule. Roman Electric runs the test, documents the result, and repairs or replaces any assembly that fails.

Is your work compliant with Wisconsin and New Berlin code requirements?

Every install follows Wisconsin electrical and plumbing code. That includes the state's current NEC adoption under SPS 316 and the plumbing rules under SPS 382. We work to City of New Berlin and Waukesha County inspection standards, and we pull permits as the job requires.

Do you provide 24/7 emergency service in New Berlin?

Yes. Our emergency line runs around the clock for urgent commercial failures. That covers power loss, water leaks, sewer backups, and life safety faults. Call 414-771-5400 for immediate dispatch.

What types of New Berlin buildings do you work on?

Manufacturing plants and machine shops, warehouses and distribution centers, offices, retail buildings, multifamily properties, and hospitality sites. Jobs range from one service call to a full electrical and plumbing package on a new build.
