Excavation Services in Seattle

Excavation is the process of digging, moving, and shaping earth to prepare a site for construction. It's the groundwork that makes everything else possible, whether you're building a house, installing utilities, or laying a foundation. Proper excavation ensures the ground is level, stable, and ready for what comes next.

Our excavation work covers foundation excavation, earthmoving and grading, site preparation, utility installation trenching, drainage pump installation, and temporary shoring. We also handle demolition, including residential, commercial, concrete, and building demolition.

Yes. We work with homeowners, general contractors, developers, and apartment community owners on both residential and commercial projects.

Volume of material moved, site access, soil and rock conditions, how far spoils have to be hauled, whether shoring or dewatering is needed, and permit requirements. A flat, open lot with good soil is straightforward; a tight urban site next to an existing structure is a different job. We look at the site before quoting.

Avoiding utility damage is one of the main challenges of any dig. We research the site and locate existing lines before excavation begins, which reduces the risk of striking utilities and helps keep the project on schedule. If you're planning a new water or sewer line, our water line and sewer pages cover the installation process in more detail.

Some gets reused on site for backfill or grading if the soil is suitable. The rest is hauled off. How much has to leave, and how far it travels, is one of the bigger swing factors in an excavation quote.
