Excavation & Foundations

Excavation & Foundations Done Right the First Time

Precision groundwork for builders and homeowners across North Idaho and Eastern Washington.

How We Do It

Accuracy in the Earth

Laser-Guided Digging

We dig to exact specifications, ensuring footings and stem walls are placed on undisturbed or perfectly compacted soil.

Compaction Excellence

A foundation is only as good as the soil beneath it. We provide rigorous compaction to prevent future settling and structural failure.

Seamless Sub-Contracting

We work in lockstep with your concrete crew, ensuring the hole is ready exactly when they need to pour.

Where every project begins

Every great structure starts with a hole in the ground, but not all holes are created equal.

In the varied terrain of the Inland Northwest, you need an operator who understands soil types, frost lines, and water tables.



Lone Mountain Excavation provides the heavy lifting for general contractors and owner-builders. We specialize in the critical window between the survey and the pour, providing a clean, safe, and accurate work environment.
