How It Works

We do an on-site visit and meet the customer. We then examine and provide information on where the best soil would be and what type of system is needed based on Washington State and local county regulations. Next, we develop the CAD drawing and submit to county. After approval the design can be bid on/installed by a Mason County licensed installer. As the final step, Pioneer Digging will then check the installation and make sure it was installed as per design.
