About Kothrade

Who Is Kothrade?

Kothrade, (pronounced 'Coth-rah-dee') is a family-owned business that focuses on providing exceptional, quality service in the Northwest Suburbs of Minneapolis, MN.

Since 1994, Kothrade has provided complete septic and sewer/water installation, maintenance and repair. We are also a full-service excavating company for both residential and commercial projects.

Mission & History

Kothrade is a leader in providing value-added sewer/water, septic, and excavating services to our customers by practicing integrity and focusing on detail. Our pledge is to establish lasting relationships with our customers by exceeding their expectations and gaining their trust through exceptional service.

Kothrade started out in business in 1994 installing septic systems and providing city sewer and water connections. As the business and housing industry grew, Kothrade added full-service excavation to their scope of services to provide comprehensive services to new home construction.

Throughout years of installation, the demand for maintenance grew, and Kothrade expanded once again to include septic and sewer service and septic tank pumping. We pride ourselves in being a 'one-stop' shop for homeowners, builders, businesses, and government municipalities; where you will find that exceptional service is the core of our business.

Kothrade is committed to community involvement from charitable work to serving on boards.

Recently, Kothrade has donated time and materials to the charitable events, 'Home for a Cure' where the proceeds benefited, Families of Spinal Muscular Atrophy.

Kothrade has also been active with the Wings of Mercy charitable organization. The owner of Kothrade serves as an on-call pilot to provide free air transportation for people with limited financial means who need treatment at distant medical facilities.

It is our goal to continue serving our communities by providing value-added, exceptional service and by continuing to give back to our area communities.
