Still Getting It Right.
DW Excavation started with a simple premise: do the work correctly, communicate honestly, and leave the site cleaner than you found it. Over a decade later, that hasn't changed.
We serve state, government, and private clients throughout California. Our crews work alongside General A, B, and C12 contractors — bringing the licenses, experience, and equipment to handle every phase of excavation and site preparation from initial clearing through final grading.
Whether you're building a new home in Sonoma County or managing drainage issues on the Monterey coast, we understand the soil, the regulations, and what it takes to stay on schedule and under budget.

On Budget.
Every Time.
At DW Excavation, we're dedicated to providing expert craftsmanship and friendly customer service at competitive rates. Honest, reliable work executed with integrity — always within budget.
We treat every property like it's our own. That means showing up on time, keeping you informed, and leaving your site in better condition than we found it. It's not complicated — it's just how we work.
The Work Speaks For Itself
Excellent service and responsive. Dallas and Josh were very accommodating in meeting with me in a timely matter and walking the property before the project's start date. The end was better than expected. DW Excavation went above and beyond to complete my project on budget — and left my property cleaner than before. Highly recommend!
Fast, friendly, and got the job done on time and on budget.
William did an excellent job clearing our 18 acres of old vineyard when no one else wanted to. They went above and beyond with the grading and ditch clearing. Their work changed the whole look of the property and allowed it to drain properly. Our property looks incredible — and they are honest and hard working!
Sonoma County
Our home base in Windsor, CA puts us right in the heart of Sonoma's wine country. We know this land — the clay soils, the hillside grading challenges, the county permit process, and the wildfire defensible space requirements.
Santa Rosa & Sonoma →Monterey County
From the farmlands of the Salinas Valley to the coastal hills of the Monterey Peninsula, we handle the drainage challenges, erosion risks, and grading requirements that define this stretch of the Central Coast.
