What Our Customers Are Saying

⭐⭐⭐⭐⭐ “House Excavating replaced our failing septic system in Potosi last spring. They handled everything with the health department, showed up on time, and left our yard looking better than before they started. Highly recommend!” – Mike R., Potosi, MO

⭐⭐⭐⭐⭐ “Best decision we made for our new home build in Jefferson City. Professional crew, fair price, and the system passed inspection the first time. Thank you!” – Sarah & David L., Jefferson City, MO

⭐⭐⭐⭐⭐ “We needed a commercial septic system for our new shop in Farmington. House Excavating beat the other bids and finished ahead of schedule. Zero issues six months in.” – Tom H., Farmington, MO

⭐⭐⭐⭐⭐ “After two other companies said our Bonne Terre lot was ‘too difficult,’ House Excavating designed and installed a mound system that works perfectly. Great communication from start to finish.” – Jennifer K., Bonne Terre, MO
