About Grundmann Builders

Built on Integrity. Driven by Quality.

At Grundmann Builders, we believe every project deserves careful planning, skilled craftsmanship, and honest communication.

Our Story

Grundmann Builders was founded with a simple goal, to provide dependable construction services backed by integrity, experience, and attention to detail. Founded by a U.S. Marine Corps veteran with more than 15 years of construction experience, our company is built on the same values of discipline, accountability, and hard work that guide every project we take on.

Based in Northern Minnesota, we proudly serve homeowners with a wide range of residential construction services, including remodeling, new construction, decks, siding, drywall, painting, and more. As a family owned business, we understand that your home is one of your biggest investments, and we treat every project with the same care and respect we would give our own.

Outside of construction, our team enjoys giving back by coaching youth sports and supporting local families throughout Northern Minnesota. Those same values of service, teamwork, and dedication are reflected in the way we approach every project and every customer relationship.
