What Professional Excavation Includes
Excavation sets up everything that follows it, so precision matters: foundation footings dug to the right depth and dimension, trenches cut to spec for utility lines, and a cleared site that's actually ready for the next trade.
It starts with utility locates — calling 811 before any digging — then moves through land clearing, excavation to spec, and grading and compaction so drainage is handled correctly from the start instead of becoming a problem after the project is finished.

Excavation FAQs
What's the difference between excavation and grading?
Excavation is digging and removing material — for foundations, trenches, or clearing a site. Grading is reshaping the surface afterward for proper drainage and a level base. Most projects need both.
Do you call 811 before digging?
Yes — utility locates are a standard part of any excavation project to avoid hitting buried gas, water, or electrical lines.
Can excavation work happen in winter?
It depends on ground conditions — frozen or saturated soil can limit what's possible. Contact us and we'll assess your site and timeline.
