Whether you're dealing with a backed-up drain, a frozen pipe in the middle of winter, or a damaged sewer line that requires excavation, we provide honest advice, quality workmanship, and straightforward service without the runaround.
Columbia Heights is an established community with many older homes, mature trees, and aging underground infrastructure.

We help homeowners and select commercial customers solve these issues with practical solutions, clear communication, and 24/7 emergency service when the situation can't wait.

We're not a large corporate contractor—we're a local crew that treats customers like neighbors. When you call MMM Underground, you'll receive honest recommendations, clear communication, and quality work backed by real field experience.
We are certified with a MUCA Pipe Layer Card and also hold Water Supply System Operator Class C and Wastewater Treatment Facility SC certifications. Select services include a 1-year workmanship warranty for additional peace of mind.
If your drain can be cleaned instead of excavated, we'll tell you. If a sewer camera inspection should be performed before digging, we'll explain why. And if excavation is the right solution, we'll clearly outline the scope of work so you know exactly what to expect.
Many service calls begin with a small warning sign before becoming a major repair. A slow floor drain may indicate a main sewer blockage. Sewer odors in the basement can point to a damaged or deteriorated pipe. During harsh Minnesota winters, frozen water lines can leave your home without running water.
We respond quickly, diagnose the problem accurately, and recommend the most practical solution for your home and budget.
Sewer camera inspections are especially valuable for home buyers, home sellers, and homeowners planning preventative maintenance. Instead of guessing what's underground, we inspect the pipe and show you exactly what's happening, allowing you to make informed decisions before minor issues become costly repairs.
We proudly serve homeowners throughout Columbia Heights and the surrounding North Metro communities. Whether you're near Central Avenue, Silver Lake Village, or one of Columbia Heights' established residential neighborhoods, we're ready to help with dependable sewer, drain, water line, and excavation services.
