Reliable Work From the Underground Up
Local Experience Since 2005
MJM Dirt Works & Septic Systems has worked with homeowners and builders across southwest Missouri for nearly two decades, handling both planned projects and urgent underground utility problems.
We Coordinate the Details
We communicate with inspectors, builders, and utility providers so the work meets requirements and keeps moving forward.
Clear, Practical Communication
You’ll know what’s happening, what needs done, and what to expect before digging begins, including access, timeline, and cleanup.

Clearing, demolition, hauling, and preparation for foundations, driveways, and construction sites.

Restoring water service and replacing damaged lines to prevent further property damage.
Work You Can Plan Around — Or Call When It Can’t Wait
Homeowners call when something stops working. Builders call when the schedule matters.
We handle emergency repairs and planned excavation so properties stay usable and projects stay on track.
If you’re unsure what the issue is yet, start with a conversation. We’ll help you understand the next step before work begins.
