Start Your Home Build with Expert Excavation You Can Trust

Getting ready to build a new home? The first step is digging it right. At Dirtworks Northwest, we provide professional residential excavation services in Bonney Lake, WA and throughout Pierce, King, and Thurston Counties. Whether you're working with a builder or managing a custom build yourself, we handle the dirt work that sets the stage for everything to come.

Let us help you build from the ground up—safely, precisely, and on schedule.

Full-Service Residential Excavation for New Construction

Our experienced crew is equipped with the tools, knowledge, and heavy machinery to tackle residential excavation projects of all sizes—from single-family homes to multi-lot subdivisions. We work closely with general contractors, custom home builders, and individual homeowners to ensure your site is prepped correctly from day one.

House Pad & Foundation Excavation

We dig for crawl spaces, basements, and slab-on-grade foundations with precision. Whether your lot is flat or sloped, we excavate to spec and help ensure your foundation sits on solid, compacted ground.

Site Clearing & Grading

We remove trees, brush, rocks, and debris to create a clean slate. Then we grade the land to ensure proper drainage and elevation based on your construction plans.

Utility Trenching (Water, Sewer, Power)

Need to run water lines, sewer pipes, storm drainage, or electrical conduit? We handle all aspects of residential utility trenching, including depth, slope, and alignment—ready for inspection and backfill.

Driveway & Access Excavation

Whether it’s gravel or concrete, we clear, grade, and compact the driveway path for proper drainage and long-term durability.

Septic System Excavation

We work with septic designers and installers to dig trenches, tanks, and drain fields to exact specifications.
