Foundation excavation is complex. Sure, you can get a cheap quote, but what exactly are you getting for the price you pay? We understand that you may be working within a budget, and that’s why we provide our customers with estimates upfront so they know exactly what they’ll receive when they hire us.

Our estimates include all the materials needed plus labor to complete the job quickly and effectively. Site preparation and foundation excavation is an investment and choosing a cheaper quote might save you money in the short term but it may mean committing to more problems further down the road; instead, choosing us ensures high-quality, premium service at a fair cost.


standard foundation excavation includes:

  • Excavation of footings
  • Installation of footing drains and downspouts
  • Tie into existing storm system or install drywell
  • Importing wash rock for footing drains
  • Importing 5/8″ minus rock for slab-on-grade construction of garages, pole barns etc.
  • Back-filling footings
  • Back-filling and compacting crawl space
  • Set rough grade around foundation

With careful planning and precise execution, we ensure that your construction project is kept on time and on track.

Site preparation services are essential; they serve as the foundation of a successful project. We specialize in excavating the necessary area for the foundation with efficiency and accuracy which assures minimal loss of time.

Foundation excavation is a key component for getting any building off the ground – and with our experienced team behind it, you’ll get it done quickly and without unnecessary financial burden.

GRADING services

Excavation is more than just digging. Grading is an expense that every project must undertake. Whether you are building your dream home, building apartment complexes, putting up a commercial building, or building a football stadium, the use of quality grading contractors will be required at some point.

Grading is NOT just moving dirt until it looks good. Oftentimes, there are engineering reasons for the way your site is graded. We use elevations from a set of engineered drawings to determine what the elevation is before and after the project is complete.

Skilled grading excavation contractor services can be used to control the drainage of a site. For instance, if you are building a single-family residence, you will want to grade a slope away from the foundation at a minimum of 2% slope. This will reduce the risk of undermining the foundation many years down the line and will save you from incurring costly foundation repairs in the future.


Our excavation services are available throughout Western Washington – Seattle, Tacoma, Bremerton, Aberdeen, Chehalis and surrounding areas!
