About Cobalt, Missouri

Cobalt is a small, unincorporated community in eastern Madison County, Missouri (ZIP code 63645), near the St. Francois County line. While exact population figures for the village itself are small – typically under 300 residents – the greater Cobalt and Annapolis area is home to friendly rural families who value hard work, open land, and self-reliance. Surrounded by the beautiful Mark Twain National Forest, residents enjoy a peaceful country lifestyle while staying within easy reach of Farmington, Fredericktown, and Arcadia Valley.

Because many properties in the 63645 area are not connected to municipal sewer systems, a properly installed and maintained septic system is essential for every home and business.

⭐⭐⭐⭐⭐ “We bought raw land near Annapolis and needed excavation, grading, and a septic system before we could build. These guys cleared the lot, installed the septic, and left the property perfectly level. Best contractor we worked with on the whole project.” – Sarah & Mike T., Madison County

⭐⭐⭐⭐⭐ “Fast response when our drain field started backing up. They came out the same week, diagnosed the issue, and replaced the field without tearing up the whole yard. Great cleanup too!” – Linda R., Near Cobalt, MO
