How to Hire a Utility Contractor Contractor

Updated March 2026

Utility contractors install and repair underground infrastructure including water lines, sewer lines, storm drains, gas lines, electrical conduit, and fiber optic pathways. This specialized work requires expertise in trenching, boring (horizontal directional drilling), pipe joining, backfilling, and compaction. Utility work is heavily regulated — permits, inspections, and compliance with depth and separation requirements are mandatory. Directional boring allows utilities to be installed under roads, driveways, and landscaping without open-cut excavation, minimizing surface disruption. For residential projects, utility contractors typically handle water and sewer line replacements, new service connections, and utility relocation.

Typical cost

$2,000 – $15,000per project

Water line replacement: $2,000–$5,000. Sewer line replacement: $3,000–$10,000. Directional boring: $10–$25/linear ft. New utility connections vary by distance and municipality.

Hiring checklist

1Verify the contractor is licensed for the specific utility type (water, sewer, gas).
2Confirm they coordinate 811 utility locates and obtain all required permits.
3Ask about their method — open-cut trenching vs. directional boring — and the pros/cons for your project.
4Get a written estimate that includes restoration of any disturbed surfaces (lawn, driveway, sidewalk).
