Old Mill Building Products has been simplifying the installation of authentic materials since 2007. Today we help architects, builders, contractors, and DIYers deliver real-material results—faster—with systems that cut labor, boost energy performance, and look timeless from day one. “Authentic by nature. Versatile by design.” isn’t just a line; it’s how we build.

We serve residential, commercial, and hospitality projects nationwide through
engineered wall systems, real clay thin brick, and architectural finishes—backed
by rigorous testing and practical job-site know-how
