Lee One Construction is a licensed excavation and septic contractor serving Anderson, Redding, Chico, and communities across Northern California, with CSLB #1063228 and 25 years of hands-on field experience behind every job we take on.


From full septic system installations to defensible space clearing, water line work, and lot development, we handle the ground-up jobs that most contractors won't touch, or can't do right. We've been on the ground in Shasta County since 2020 and work across the full Northern California region seven days a week, around the clock.


If the job involves earth, pipe, or grade, we do it. Explore the services below and call us the same day.

Common Questions About Our Northern California Services


  • Which service do I need if I'm building on raw land in Northern California?

    Most raw land builds in Northern California need at minimum a perc test, a septic permit application, and full septic system installation before construction can be completed. If the lot also needs grading, utility trenching, or a sewer lateral, Lee One Construction handles all of those under one CSLB-licensed crew, no need to coordinate multiple contractors.

  • Does Lee One Construction handle the permit process for septic systems?

    Yes. Lee One Construction prepares and submits the full permit application to Shasta County Environmental Health on your behalf, including perc test documentation and engineered system design drawings. We've completed this process many times in Shasta County and know exactly what the office requires to approve an application on the first submission.

  • How do I know if I need septic repair or a full system replacement?

    The answer depends on which components have failed and the age of the existing system. A damaged distribution box, collapsed pipe, or saturated drain field section often warrants targeted repair. A system that has failed multiple times, is undersized for the current use, or predates modern Shasta County code standards typically requires full replacement. Lee One Construction diagnoses on-site before recommending either path.
