What We Trench
Water and sewer laterals, electrical and communication conduit, drainage and French-drain runs, irrigation, and gas-line trenches where permitted. We work to the depths and widths your plumber, electrician, or engineer specifies, including tight residential lots and longer rural runs.
How A Trenching Job Runs
- Call or send the site address, utility type, approximate length, and any drawings.
- We walk the site, confirm locates, and give a fixed price.
- We trench, bed the line if that is in scope, and backfill. You get a clear start date, not a vague window.
Built For Montana Ground
Stillwater and Yellowstone County soils, frost, and rock change how a trench is cut and restored. We plan for that instead of treating Montana dirt like a generic suburban lot.
