What Our Femme Osage Customers Are Saying

⭐⭐⭐⭐⭐ “House Excavating installed a new mound system on our 5-acre property in Femme Osage after our old tank failed. They handled everything – permits, perc test, excavation, and final grading. Professional crew, showed up on time, and left the yard cleaner than when they arrived. Highly recommend!” – Mark & Sarah T., Femme Osage, MO (March 2025)

⭐⭐⭐⭐⭐ “We needed emergency septic repair after heavy spring rains flooded our drain field. They came out the same day (on a Saturday!), pumped the tank, and fixed the field lines. Saved our weekend family reunion! Best septic company in St. Charles County.” – Jennifer R., Defiance, MO (May 2025)

⭐⭐⭐⭐⭐ “Did a complete commercial septic install for our new winery tasting room near Augusta. Worked directly with the health department and passed inspection the first time. Fair price and excellent communication throughout the project.” – Daniel K., Augusta, MO (January 2025)
