About Imperial, Missouri

Imperial is an unincorporated community and census-designated place in Jefferson County with a growing population of over 4,900 residents (2023 estimate). Located just 25 minutes south of St. Louis along I-55 and Highway 21-67, Imperial offers the perfect mix of rural acreage living with quick access to city amenities. New housing developments in the Seckman, Windsor, and Antonia areas continue to drive demand for professional septic installation as city sewer lines do not extend to most properties here.

Our Most Recent 5-Star Customer Reviews (Google & Facebook)

★★★★★ “House Excavating replaced our 40-year-old septic system in Imperial last month. They pulled permits, passed all inspections on the first try, and left the yard cleaner than when they started. Fair price and excellent communication. Highly recommend!” – Jennifer R., Imperial, MO (October 2025)

★★★★★ “Needed a new drain field after heavy rains flooded the old one. These guys came out the same day I called, diagnosed the issue, and had the new field installed in three days. Professional crew and heavy equipment that got the job done fast.” – Mike T., Barnhart, MO (September 2025)

★★★★★ “Best excavation company in Jefferson County, hands down. They graded our 5-acre lot, installed French drains around the house, and put in a new 1,500-gallon septic system for our new build. Everything passed county inspection with zero issues.” – Sarah & David L., Hillsboro, MO (August 2025)
