Why Saint John Homeowners & Businesses Trust House Excavating LLC

Saint John, Missouri is a small, close-knit city in St. Louis County with a population of approximately 6,800 residents (2023 estimate). Despite its compact size of just 1.4 square miles, the community features a mix of older homes built in the 1940s–1960s and newer commercial developments along St. Charles Rock Road. Many properties here were originally built with outdated septic systems or have aging drain fields that no longer meet current St. Louis County health department standards.

At House Excavating LLC, we specialize in bringing these systems up to code with modern, environmentally safe septic installations that protect both your property and Lambert-St. Louis International Airport’s nearby groundwater.

What Our Saint John Customers Are Saying

★★★★★ “House Excavating replaced our failing 60-year-old septic system in Saint John last spring. They handled everything – permits, perc test, removal of the old tank, and installed a new 1,000-gallon system with a new drain field. Professional, on-time, and cleaned up better than when they arrived. Highly recommend!” – Mike R., Brownleigh Ct, Saint John, MO 63114

★★★★★ “We own a small strip mall on St. Charles Rock Road and needed a commercial grease trap and septic upgrade. House Excavating gave us a fair price, pulled all permits, and finished ahead of schedule. Zero complaints from tenants during the project.” – Jennifer T., Commercial Property Owner, Saint John

★★★★★ “After heavy spring rains, our backyard in the McCurdy Ave area was constantly flooded. They installed French drains and re-graded the entire yard. Problem solved – and it’s held up perfectly through this year’s storms.” – Sarah K., Saint John Resident

★★★★★ “Fast response when our septic backed up on a Friday night. They pumped the tank that evening and came back Monday to install a new riser and baffle. Honest pricing and great communication.” – David L., Ruth Dr, Saint John, MO
