What GF Five Star Energy Services does
Five Star Energy Services (legal name: Five Star Infrastructure Services LLC) is a Waukesha, Wisconsin-based private LLC founded in 2020 that provides turnkey underground utility construction services across four vertical segments: telecommunications (fiber optic OSP/ISP construction, aerial construction, fiber splicing, fiber blowing, design engineering), natural gas distribution (main and service installation, tapping and welding, maintenance, cross-bore inspection), electric utilities (URD construction, pole setting and removal, overhead-to-underground conversion), and sewer and water infrastructure (main installation, emergency repair, cross-bore mitigation). The company supports field execution with GIS mapping, GPS surveying, sewer camera inspection (mainline and lateral), and sewer mainline jetting. Five Star operates across approximately 16 U.S. states with 1,600+ to nearly 2,000 employees, supported by a network of regional offices, yards, and operations support facilities in Wisconsin, Colorado, Michigan, Illinois, North Carolina, Indiana, Minnesota, Missouri, and New York.
Five Star generates revenue through project-based, one-time construction contracts awarded by enterprise telecom carriers (Verizon, AT&T, Charter/Spectrum, TDS, Lumos), regulated utilities (WE Energies, Xcel Energy, CenterPoint Energy, MGE Energy), and municipal governments (City of Milwaukee, City of Denver, City of Detroit). Pricing is custom and quote-based per project scope with multi-year contract cadence. The go-to-market is direct B2B field sales with no resellers or intermediary channels. Five Star positions itself as a value-added partner rather than a commodity contractor, with union labor, in-house execution across design, survey, and installation, and a stated safety-first operating culture. The company is family-controlled, with Grant Klumb as CEO, Mike Klumb as Chairman of the Board, and Shawn Klumb as EVP of Fleet, supported by a divisional bench of Presidents and VPs across Telecom, M&C, Pipeline, Water, Operations, HR, IT, Professional Services, and EHS.
Growth has been driven primarily by geographic expansion and inorganic moves. On September 11, 2025, Five Star acquired Waunakee, Wisconsin-based InterCon Construction (founded 1984), strengthening natural gas and electrical capabilities in core Midwest regions. The firm also operates M&C Utilities as a subsidiary brand serving Northeast markets from Buffalo, NY. Five Star maintains no public revenue disclosure, no disclosed external funding, no public listing, and no documented AI/ML capabilities.

GF Five Star Energy Services competitors and assessment
Company assessmentBroad incumbents
- MasTec: MasTec is a publicly traded infrastructure construction company serving the communications, utility, oil & gas, and clean energy markets. It is a broad incumbent peer to Five Star, with comparable telecom fiber and gas/electric distribution service lines, though MasTec is national in scale and far larger.
- Primoris Services: Primoris Services provides construction and infrastructure services across utilities, energy, and civil markets. Its utilities segment covers electric T&D, gas, and telecom — directly comparable to Five Star's service mix — but operates at a larger scale with broader civil and energy exposure.
- Quanta Services: Quanta Services is the largest publicly traded utility infrastructure construction company in North America, offering electric, gas, telecom, and renewable EPC services. It is the broad incumbent comparable to Five Star's multi-vertical turnkey model, although it operates at vastly larger scale and includes transmission and substation work beyond Five Star's scope.
Direct peers
- MYR Group: MYR Group is a publicly traded specialty contractor focused on electrical construction (T&D, commercial & industrial). It is a direct peer for Five Star's URD electric and underground distribution work, though MYR is more concentrated in electric and lacks the telecom and gas/water breadth.
- Henkels & McCoy: Henkels & McCoy is a privately held infrastructure contractor providing engineering and construction services for the electric, gas, and telecommunications markets. It is a direct peer to Five Star across all three of its core verticals, with comparable scale and union labor model.
- MCI Holdings: MCI Holdings is a privately held specialty contractor providing underground utility construction for the electric, gas, and telecommunications industries. It is a direct mid-market peer to Five Star, with comparable scope, customer type, and project-based delivery model.
- Miller Pipeline: Miller Pipeline is a privately held utility construction company specializing in natural gas distribution, pipeline construction, and maintenance services. It is a direct peer for Five Star's Gas Distribution line (main/service installation, tapping & welding, cross-bore mitigation).
- Dycom Industries: Dycom Industries is a publicly traded specialty contractor providing construction and maintenance services to the telecommunications industry, including fiber optic network deployment. It is a direct comparable for Five Star's Fiber Optic Construction line (OSP/ISP, splicing, design engineering) and shares the same telecom customer base (Verizon, AT&T, Charter).
- Pike Electric: Pike Electric is a privately held provider of construction and maintenance services to the electric utility industry, including overhead and underground distribution. Comparable to Five Star's URD electric construction, with a similar multi-customer utility model.
Regional players
- Trans-Tel Central: Trans-Tel Central is a privately held telecommunications construction and engineering company serving carriers across the Midwest. Regional peer to Five Star's telecom fiber business, with comparable OSP/ISP capabilities but a narrower geographic and service footprint.
