About Apex Underground

Your Colorado Experts in Underground Utility Repair Since 1985

Apex Underground, proudly serving the Denver Metro area and Colorado’s Front Range since 1985, specializes in underground utility repair and replacement. What began as a family-run plumbing company has evolved into a trusted name for residential, commercial, and municipal water and sewer line services.

Known as “The Underground Guys,” we’re recognized for our skilled crews, advanced equipment, and turn-key restoration work—from concrete and asphalt to landscaping. In 2022, we became a 100% employee-owned company, reflecting our deep commitment to quality, accountability, and long-term service.  With a 5-year transferable warranty and a team focused on getting the job done right, Apex Underground is proud to be Colorado’s go-to source for utility excavation and repairs.
