How Much Does Excavation Cost in Snohomish & Skagit County?
Excavation is one of the hardest home projects to price from the couch. A driveway regrade and an ADU sewer line are both "excavation," but they can differ in cost by thousands of dollars. This guide covers typical price ranges, what drives the cost up or down, and how to compare estimates so you're not surprised by the final bill.
Typical Excavation Costs
Prices vary by contractor, site, and scope, so treat these as general ballparks, not quotes. Ranges below come from national and Seattle-area pricing guides, and local rates can differ.
Typical residential excavation project: roughly $1,700 to $6,700, with an average near $4,000
Yard regrading: roughly $500 to $1,000 for small jobs, and about $1,000 to $5,000 for a typical backyard
Land clearing: roughly $1,400 to $5,800, depending on acreage and how many trees
Basement dig-out for new construction: roughly $4,800 to $8,400 or more
Larger jobs like full site prep, utility trenching, or multi-day work cost more. Pricing for one-off hauling or material delivery is usually quoted per load or per hour.
What Affects Excavation CostSize and Depth
More ground moved means more time, more fuel, and more hauling. Depth matters as much as area, since digging deeper takes longer and often needs more care.
Soil Conditions
Soft or sandy soil digs easily. Heavy clay, rock, or buried boulders slow the work and wear on equipment. Soil problems can add a few hundred to over a thousand dollars, and they're one reason a contractor wants to see the property before quoting.
Access and Terrain
A flat lot with room for equipment is cheaper to work on than a steep, wooded, or tight site. Limited access can mean smaller machines and more time.
Hauling and Disposal
Digging is only half the cost. Excess dirt has to go somewhere, and hauling adds trucking time. If material is being delivered, such as fill dirt, rock, or topsoil, that's priced separately from the digging.
Water and Season
Wet ground is harder to dig, hauls heavier, and can require drainage or erosion control. Wet-season work in Western Washington often costs more than the same job in a dry stretch.
Permits and Surveys
Some projects need permits, utility locates, or a survey. National guides put permits and surveys at roughly $750 to $2,750 on larger projects, though many small residential jobs need little or none.
Utilities
Washington requires a call to 811 at least two business days before any dig, so utility lines can be marked for free. Work near existing utilities or running new sewer, water, or electrical lines adds time and complexity.
Timing and Availability
Late spring through early fall is the busiest season. Booking early can save you a wait, and short-notice work may cost more.
How Excavation Contractors Price Jobs
Contractors generally price in one of three ways:
By the hour: a set rate for machine and operator, common for smaller or unpredictable jobs
By the project: a fixed price for a defined scope, common for driveways, clearing, or foundation digs
By the load or yard: common for hauling and material delivery
A fixed price gives you certainty if the scope is well defined. Hourly billing can be fairer when the job has unknowns, like hidden rock, but ask for an estimated number of hours so it's not open-ended.
How to Get an Accurate Estimate
Have Someone Walk the Property
A quote given over the phone for a job the contractor hasn't seen is a guess. An on-site visit lets them check soil, slope, access, and where the material will go.
Ask What's Included
Confirm whether hauling, fill or rock, grading, cleanup, and finish work are in the price. A low number that leaves out hauling isn't a low number.
Get Estimates for the Same Scope
Give each contractor the same description so the quotes can be compared fairly.
Ask About Surprises
Ask how unexpected conditions, like rock, buried debris, or poor soil, are handled and priced before work starts.
Check Registration and Insurance
Washington contractors must be registered with the state Department of Labor & Industries, and you can look up registration, bond, and insurance status on the L&I website.
Ways to Keep Costs Down
Book in the drier months when possible
Bundle related work, such as clearing, grading, and hauling, with one contractor to avoid paying for extra mobilization
Clear out fences, planters, and obstacles in the work area beforehand
Have your utility locates and any needed permits sorted early so the crew isn't waiting
Decide the scope before the work starts, since mid-project changes cost more

FAQ Section:
Q: What's included in an excavation estimate?
A: A good estimate should spell out the digging, grading, hauling of excess dirt, any rock or fill material, and cleanup. Ask each contractor to list what's included so you can compare quotes fairly. Walton Excavation and Trucking gives free on-site estimates throughout Snohomish and Skagit County.
Q: How much does it cost to excavate for a driveway or yard project?
A: Small regrading jobs often run a few hundred to a thousand dollars, and a typical backyard regrade can reach about $5,000. Driveways and larger projects depend on length, depth, base material, and hauling.
Q: Why do excavation quotes vary so much between contractors?
A: Scope, equipment, hauling, and how the contractor handles unknowns like rock or poor soil all differ. Comparing quotes only works if they cover the same job, so ask what's included in each one.
Q: Does excavation cost more in the rainy season?
A: It can. Wet ground is harder to work in, heavier to haul, and may need drainage or erosion control, so the same job can cost more in winter than in late spring or summer.

A: Yes. Walton offers free on-site estimates throughout Snohomish and Skagit County, including Tulalip, Marysville, Everett, and Mount Vernon. Call (425) 645-9588 to schedule one.
