OMC offers high quality window options for your home, historical project, church and other niche buildings. OMC also offers new construction windows and doors for apartment complexes, condos and other large scale housing projects. Our PVC trim and molding products are guaranteed to never warp, splinter, or rot from water damage. While not required, PVC material is able to be painted. Our PVC trim and molding products hold a finish much better, and much longer, than any wood based products. Olsen Mastermark Company (OMC), located in Lansing, Michigan, has been working in the building industry since 1982.
We have been serving the Greater Lansing Area since 1982 and now offer services all throughout Central Michigan as well as nationwide and beyond! Whether you walk in our shop or contact us from half a world away, you can count on quality customer service from a small family run Mid-Western company. We have been evolving since we first opened as a lumber yard nearly 40 years ago. From selling building supplies to manufacturing windows in our warehouse to expanding into highly specialized custom made trim and CNC precision historical restoration, we have continued to be a unique provider of the highest quality products available.
