New Construction Sewer Line
Complete sewer lateral installation from the foundation to the municipal main — sized, graded, and permitted for your specific project.
ADU & Addition Sewer Connection
New sewer tie-ins for accessory dwelling units, room additions, and backyard structures that require a dedicated or shared lateral.

What We Do
New Sewer Lines Installed Right the First Time
Planning an ADU, a home addition, or building on a lot without sewer service? A proper sewer line installation sets the foundation for everything else. Get it wrong, and drainage problems follow the building for decades. We handle new sewer lateral installations from the building to the municipal connection, tie-ins for ADUs and additions, sewer reroutes for remodels, and cleanout installations required by current California plumbing code. Our licensed plumbers manage the full scope — site assessment, trenching, pipe installation, inspections, and backfill — with minimal disruption to your property.
