MDC Contracting rebranded to Manthei Construction in 2021. At Manthei Construction, we provide construction services for site development, underground systems, ready-mix concrete, and aggregate processing. We are also a producer of outdoor hardscapes, and a supplier of landscape materials for the region.

In 2021 we introduce to you Manthei Supply. Our newly expanded yard and showroom is a resource to local architects, contractors, designers and homeowners. We are open to the public. Come use our space as a tool for planning, and purchase materials for your next landscape project!
