3L Excavating and Utilities Inc.

3L Excavating and Utilities Inc. is an experienced Excavating contractor, Demolition contractor, and Utility contractor handling site prep, grading, trenching, foundation digs, utility installations, and safe structural/demo work in the Denver area. For a smooth start, request a site walk and a line-item estimate with timelines that account for permits, 811 utility locates, traffic control, and inspection milestones. Ask about soils and rock contingencies, trench safety/shoring, erosion control, groundwater management, and haul-off/recycling plans so you know how they’ll handle hard digs and disposal. Before booking, confirm current licensing/insurance, get references for similar work (water/sewer services, storm drains, selective demolition), and secure a clear restoration plan for paving, landscaping, and final cleanup.
