Why Crestwood Homeowners & Businesses Trust House Excavating LLC

Crestwood, MO – a beautiful inner-ring suburb of St. Louis with a population of just over 12,000 residents (2023 estimate) – is known for its quiet neighborhoods, excellent schools, and mix of mid-century homes and newer construction. Many properties in Crestwood and the surrounding 63126, 63123, and 63122 zip codes are not connected to municipal sewer lines, making a properly designed and installed septic system essential for every home and business.

• New septic system installation (conventional & alternative systems)
• Septic tank and drain field replacement
• Lateral line and leach field repair or expansion
• Complete excavation and land grading for new construction

What Our Crestwood Customers Are Saying

⭐⭐⭐⭐⭐ “House Excavating replaced our failing septic system in Crestwood last spring. They were on time, kept the yard clean, and the new drain field works perfectly. Best price out of three bids and excellent communication!” – Sarah T., Crestwood, MO (July 2025)

⭐⭐⭐⭐⭐ “We needed a new commercial septic system for our strip mall on Watson Road. House Excavating finished the job ahead of schedule and passed county inspection on the first try. Highly recommend!” – Mike R., Business Owner, Crestwood/Sunset Hills border (May 2025)

⭐⭐⭐⭐⭐ “After heavy spring rains, our backyard was constantly flooded. House Excavating installed French drains and re-graded the entire lot. No more soggy yard – and they saved several mature trees in the process. True professionals. – The Johnson Family, Grant’s Trail area, Crestwood (April 2025)

⭐⭐⭐⭐⭐⭐ “Fast response when our old tank collapsed. They had a new septic system designed, permitted, and installed in under two weeks. Clean work and fair pricing. Couldn’t ask for better service in Crestwood.” – David L., Whitecliff Park neighborhood (September 2025)
