About

With over 43 years of continuous operation in southeast Wisconsin, NSI Electrical Contractors Inc. brings deep-rooted commercial and industrial electrical expertise to facility managers and property owners across the Milwaukee metro. Now operating from their expanded facility in New Berlin, WI, NSI is a family-owned contractor built around long-term client relationships and hands-on project management for commercial, industrial, and multifamily residential properties. Their scope spans the full range of commercial electrical work: power distribution upgrades, panelboard and breaker replacements, switchgear service, comprehensive lighting systems and relamping campaigns, and new construction wiring for office, retail, warehouse, and industrial facilities. For facility managers juggling tenant demands or capital improvement schedules, NSI offers 24-hour emergency electrical service — a critical capability when production lines, HVAC systems, or life-safety circuits go down outside business hours. Their construction and remodeling division handles tenant improvements and building system upgrades, while their maintenance and repair services keep aging electrical infrastructure in code-compliant, efficient operation. NSI's relamping and lighting retrofit work is particularly relevant to property managers targeting energy cost reductions across multifamily and commercial portfolios. The firm's 40-plus-year track record in the Milwaukee and southeast Wisconsin market means their crews understand local utility requirements, Wisconsin Electrical Code applications, and the practical challenges of working in occupied commercial buildings and active industrial plants. Whether coordinating a complex industrial installation on a tight timeline or managing a phased lighting upgrade across a retail center, NSI positions itself as a single-source electrical contractor capable of design, project management, and field execution. Facility managers and general contractors in the greater Milwaukee area seeking a proven, responsive commercial electrical partner with emergency availability should consider NSI Electrical Contractors Inc. for their next project.
