Stone Fox Construction is a family-owned excavation and septic contractor serving North Idaho and Eastern Washington. We work with homeowners and builders who need reliable site work, clear communication, and results they can trust.

With over 11 years of industry experience, our team specializes in excavation, septic system installation, drainage, demolition, and site preparation for residential and rural projects. We are fully licensed, bonded, and insured, including certification for advanced septic treatment systems and Infiltrator products. Safety, accuracy, and long-term performance guide every project we take on.

We believe successful projects start with clear expectations.

During construction, clients receive consistent updates and progress photos, so they always know what’s happening on their property.

Our work includes trenching, foundations, grading, retaining walls, septic installations and repairs, drainage solutions such as French drains, and demolition services including tree, stump, and debris removal. Whether preparing land for a new build or solving site-specific challenges, we approach every project with care and attention to detail.

Much of our work comes from repeat clients and referrals, a result of honest service, dependable scheduling, and clean job sites. We take pride in completing projects on time and leaving properties ready for the next phase of construction.
