Why Sappington Homeowners & Businesses Trust House Excavating LLC

Sappington, Missouri – an unincorporated community in South St. Louis County with approximately 7,800 residents – continues to grow while maintaining its quiet, family-friendly atmosphere. Many homes here were built before city sewer lines reached the area, which means thousands of properties still rely on properly designed and installed septic systems. Whether you’re building a new home off Tesson Ferry Road, adding square footage in the Grantwood Village area, or replacing a failing system near Gravois and Baptist Church Road, you need an excavating contractor who knows local soil conditions and St. Louis County Health Department regulations inside out.

We specialize in:

• New septic system installation (conventional, chamber, mound, and aerobic systems)
• Septic tank replacement & pump-outs
• Drain field / leach field repair and replacement
• Land grading & site preparation
• French drain installation
• Complete excavation services for home additions and new construction

What Our Sappington & South County Customers Are Saying

⭐⭐⭐⭐⭐ “House Excavating replaced our 40-year-old septic system in Sappington last month. They handled everything – permits, soil testing, tank removal, new install, and final grading. Professional crew, showed up on time, and left the yard cleaner than when they arrived. Highly recommend!” – Mike & Sarah T., Sappington, MO (October 2025)

⭐⭐⭐⭐⭐ “After heavy spring rains flooded our basement twice, we called House Excavating for French drains. They graded the yard perfectly and tied everything into a new drain field extension. No water issues since. Best money we’ve spent on this house!” – Jennifer R., Crestwood (serving Sappington area)

⭐⭐⭐⭐⭐ “We were building a new home off Pardee Road and needed the lot cleared, graded, and septic installed, and driveway base put in. One call to House Excavating and everything was done on schedule and under budget. True professionals.” – Chris L., Sunset Hills / Sappington border

⭐⭐⭐⭐⭐ “Commercial septic install for our new strip mall on Watson Road. They navigated all the county inspections without a single callback. Fast, clean, and fairly priced.” – South County Plaza LLC
