High-Quality Excavation.
No Shortcuts.
Our Approach
Cornice Excavation is a North Idaho excavation and sitework company focused on doing the job right from the start. We work with homeowners, builders, and contractors to deliver dependable excavation, sitework, and earthwork across a wide range of residential and commercial projects.
Our services include site preparation and excavation, grading, building pads and foundation excavation, utility trenching and septic systems, roads and driveways, land clearing, drainage and water management, finish grading, and backfill and compaction. Every project is approached with precision, efficiency, and a clear plan from the first cut to final grade.
We understand that excavation is one of the most critical phases of any project. The quality of the work done at this stage directly impacts everything that follows. That’s why we prioritize proper grading, drainage, and site preparation, not just to meet requirements, but to ensure long-term performance.
Cornice Excavation is built on consistency and accountability. We show up when scheduled, communicate clearly throughout the project, and execute the work the right way. Our job sites are organized, our equipment is well-maintained, and our standards stay high from start to finish.
Whether it’s a single project or ongoing work with a builder, we bring the same level of focus and reliability. The goal is simple: deliver clean, accurate work that keeps your project moving forward without unnecessary issues or delays.

Our Process
1. Site Review & Scope Alignment
Every project starts with a thorough review of the site, plans, and requirements. We evaluate access, elevations, soil conditions, drainage, and the full scope so nothing is missed upfront.
2. Planning & Pre-Execution
Before equipment ever shows up, the work is mapped out. Grades, elevations, drainage paths, and sequencing are planned in advance to ensure everything ties together correctly.
3. Precise Execution
Work is completed with accuracy and efficiency using the right equipment and techniques. Cuts are clean, grades are correct, and everything is done with attention to detail from start to finish.
4. Final Grade & Clean Finish
The site is finished properly. Final grading is dialed in, drainage performs as intended, and the job is left clean, organized, and ready for the next phase.
