Why Portage des Sioux Homeowners & Businesses Choose House Excavating LLC

Nestled along the Mississippi River just north of St. Louis, the charming village of Portage des Sioux (population ~990 as of recent counts) offers peaceful rural living with easy access to metropolitan amenities. Many homes and small businesses here rely on septic systems rather than municipal sewer lines, making proper installation and maintenance critical. Poorly installed systems can lead to costly backups, ground saturation, and even environmental issues along the riverfront.

At House Excavating LLC, we understand the unique soil conditions in the 63373 area — from the heavy clay common in St. Charles County to the sandy loams near the rivers. Our team designs and installs code-compliant septic systems and drain fields that work reliably for decades.
