Our Comprehensive Process



At Messner Builders, we know that a residential building project in Winthrop, MN, and the surrounding areas involves far more than just assembling materials or replacing the old with the new. That’s why we follow a thorough, step-by-step process for every project, ensuring clarity, quality, and peace of mind. We begin with a consultation to hear your ideas and goals, then take precise on-site measurements and photos to guide the design. Detailed drawings are created to estimate costs and secure the necessary permits. We review the proposal with you, allowing time for questions or adjustments before converting it into a contract. A pre-construction meeting follows to outline the project and provide a timeline for completion. Once construction is finished, we conduct a complete walkthrough to ensure your satisfaction. This meticulous process is applied to every project, from small upgrades like window replacements to extensive home additions, guaranteeing professional results and a seamless experience.
