What Our Dardenne Prairie Customers Are Saying

⭐⭐⭐⭐⭐ “House Excavating installed a new septic system and graded our 3-acre lot in Dardenne Prairie last spring. They handled everything from permits to final inspection.

⭐⭐⭐⭐⭐ “We needed a commercial septic system for our new veterinary clinic off Bryan Road. House Excavating beat two other bids and finished ahead of schedule. Zero issues with St. Charles County health department inspections. These guys know what they’re doing.” – Dr. Jennifer R., Dardenne Prairie, MO

⭐⭐⭐⭐⭐ “After heavy rains flooded our basement twice, House Excavating installed French drains and re-graded around our home in The Forest subdivision. No water problems since – even with the crazy storms we’ve had this year. Thank you!” – The Thompson Family, Dardenne Prairie, MO 63368
