About the Business
4G Plumbing & Heating, Inc. has operated in Missoula since 1964, when Gordon and Geniece Jensen and Glen and Geneva Petit started the business. It incorporated in 1971 and expanded over time into broader mechanical, excavation and electrical work.
The company handles commercial and industrial plumbing and mechanical projects from planning and budgeting through startup. It works as a prime contractor or subcontractor on competitive-bid, plan-and-specification and design-build projects, while a service department handles residential and commercial plumbing and HVAC calls.
Its staff model is built around licensed trades and advancement. The company reports master plumbers, journeymen, sheet-metal workers and registered apprentices, with some employees moving from shop positions through apprenticeship and into foreman or project-management roles.
4G moved to West Harrier Drive in the Missoula Development Park in 2008. Independent consumer-review volume is limited, but public permit listings attribute recent work to the company at Community Medical Center, University of Montana facilities, banks and commercial remodels around Missoula.
