A Great Build Starts Below the Surface
Every foundation, basement and addition is only as good as the dig beneath it. Poor excavation shows up later as cracked footings, settling slabs, wet crawlspaces and failed drainage. Getting it right at the start costs far less than fixing it after.
What is excavation?
Excavation is the process of digging, moving and shaping soil to prepare a site for construction. It typically includes foundation and basement digs, utility trenching, hauling, backfill, compaction and final grading.
Whatcom Excavation handles the full scope with one local crew and our own equipment, so there’s no juggling separate diggers, haulers and grading contractors. You get one plan, one price and one team accountable for the result.

What Our Excavation Includes
Every project is different, so we build the scope around your property and your plans. Most jobs include some or all of the following.
Site Evaluation & Layout
We walk the property, review your plans, check access, soil and slope, and mark out the dig area.
Utility Locates
811 locates called before digging, and private lines like septic or irrigation identified on site.
Topsoil Stripping
Organic topsoil is stripped and stockpiled for later landscaping, so it isn’t left under your foundation.
Foundation & Basement Digs
Excavation to plan depth for footings, basements, crawlspaces, shops and ADUs.
Utility & Drainage Trenching
Trenches for water, sewer, power and footing drains, dug to the right depth and grade.
Dewatering & Shoring
Groundwater pumped and trench walls protected so the dig stays safe and stable.
Hauling & Material Import
Excess spoils hauled off site, and gravel, crushed rock or structural fill brought in as needed.
Backfill & Compaction
Material placed in lifts and compacted around foundations and pipes, so nothing settles later.
Final Grading & Cleanup
Ground shaped to slope water away from your structure, and the site left clean and ready for the next trade.
Excavation Built for Whatcom County Conditions
Our region’s long rainy season, high water tables and dense glacial soils make excavation here different. Open trenches fill with water, soft ground shifts under heavy machines, and poor backfill leads to settling under your foundation, slab or driveway.
We plan for water before we dig, use the right equipment for the ground we’re working in, and backfill and compact in proper layers, so your foundation and utilities stay solid long after the job is done.
Water Management
Groundwater and runoff controlled so trenches stay dry and stable.
Proper Backfill
Compacted in layers with the right material, so nothing settles later.
Erosion Control
Sediment kept on site to protect streams, ditches and neighbors.

What Affects the Cost of Excavation?
No two digs are the same, which is why we price every project after seeing it in person. These are the biggest factors that shape your estimate.
Our estimates are free, written and itemized, so you can see exactly where your budget goes.
Size & Depth
How much soil needs digging, and how deep you go.
Soil & Rock
Hard clay, glacial till or rock slows digging.
Site Access
Tight lots or steep driveways affect machine size.
Hauling & Disposal
Truck loads and dump fees for excavated material.
Import Material
Gravel, crushed rock or fill brought in for backfill.
Water & Drainage
Groundwater or wet soils may need pumping and drains.
Permits & Inspections
Grading permits, engineering and critical-area rules.
Clearing & Demolition
Trees, stumps, old concrete or debris removed first.

Excavation FAQs
Planning a build and have questions about your lot? Call us and talk to the people who’ll actually do the work.
We handle residential and light commercial excavation across Whatcom County, including foundations and basements, home additions, ADUs, shops, utility trenches, pond and drainage work, and backfill and compaction. If your project involves moving dirt, we can usually help or point you in the right direction.
Many projects do, especially foundations, larger grading and fill jobs, and work near wetlands, streams or steep slopes. Requirements depend on whether you’re in Bellingham city limits, another city, or unincorporated Whatcom County. We’ll tell you what likely applies to your project and work alongside your permits so the job passes inspection.
We do. Washington law requires underground utilities to be located before any excavation, and we take care of the 811 locate request before our crew starts. Private lines such as septic systems, irrigation or a line to a detached shop aren’t marked by 811, so let us know about any you’re aware of.
Northwest Washington’s wet season can turn soils soft and muddy, so we plan for it. That can mean scheduling around heavy rain, protecting open excavations, managing runoff with erosion control, and making sure backfill is properly compacted. We’ll give you a realistic timeline that accounts for the season.
Cost depends on the size and depth of the dig, soil and rock conditions, site access, how much material needs to be hauled away or brought in, and any permits involved. Because every site is different, we visit your property and give you a clear, free written estimate with no surprise charges.
Yes. We own and maintain our own machines, so we’re not waiting on rental availability, and we bring equipment sized for your site, from tight residential lots to larger rural properties. Start dates depend on scope, permits and weather, but being local to Whatcom County means we can usually schedule site visits quickly.
