Septic Installation & Repair

Cowan & Sons LLC provides septic system installation and repair services licensed through the State of Colorado. We hold a NAWT certification and an OWTS license for work in Chaffee and Lake Counties, and we are fully licensed and insured. Because every property and system is different, we work closely with engineers and homeowners to ensure each septic system is properly designed, installed, or repaired to meet site conditions and local regulations.

All septic projects are quoted individually based on soil conditions, system design, and site requirements. We’re happy to review project details and provide a clear, straightforward estimate. When appropriate, we’re willing to match quotes from other certified local installers for comparable systems and scope of work. Our focus is on delivering compliant, reliable septic systems built for long-term performance.
