Our Comprehensive Excavation Services

DW Excavation delivers a full range of excavation services in Sonoma County tailored to both residential and commercial jobs, ensuring clean, efficient site preparation with precision and professionalism.

Land Clearing and Preparation

We clear brush, trees, and debris; strip organics; and balance or export spoils to create a stable, build-ready surface. Protection of retained assets and sediment controls keeps the work area tidy and compliant from the first cut.

Trenching for Utilities

Our team installs trenches for water, sewer, electrical, and communications with precise depths, bedding, and backfill, keeping separations and cover in line with typical codes. Safe ingress/egress, spoil placement, and traffic control help minimize disruption and risk.

Pond Installation

We excavate, contour, and compact ponds for irrigation, habitat, or aesthetics, evaluating soils, water table, and inflow/outflow to promote stability. Liners, berm shaping, and spillway considerations are planned up front to reduce seepage and erosion over time.

Foundation Excavation

We cut, over-excavate (when needed), and fine-grade building pads for structural reliability—managing export/import to hit target elevations. Clean edges, correct setbacks, and drainage awareness prepare your foundation crew for a faster, cleaner pour.

Grading Services

From rough cut to finish grade, we shape sites to design elevations for pads, roads, and landscape, prioritizing positive drainage and erosion control. Our grading supports stability, stormwater intent, and inspection readiness throughout construction.

Our 4-Step Process

Consultation & Due Diligence

We walk the site, review goals, soils, access, and utilities; identify permitting needs; and provide a clear scope, sequence, and estimate so you can decide with confidence. 

Buildable Plan, Sequencing & Controls

We translate design into a field-ready plan, haul routes, staging, erosion controls, safety, and inspection checkpoints, sequenced to keep crews productive and your project moving. 

Precision Field Execution

Operators and labor work to spec with verified elevations, safe trench practices, and clean housekeeping; we coordinate with other trades to reduce conflicts and idle time. 

Closeout, As-Builts & Handover

We finalize grades, stabilize disturbed areas, document utilities and elevations, and hand over as-builts so subsequent trades can mobilize faster and inspectors can sign off smoothly.
