At KO Plastering, we are a trusted name in the home renovation industry, serving homeowners across Hartford, WI, Milwaukee, and surrounding areas with high-quality services designed for long-term durability. We specialize in EIFS, plastering & stucco, carpentry & deck services, drywall installation & repair, interior & exterior painting, and siding installation & repair. As a certified and insured business, we offer peace of mind and professional-grade results on every project.

Our company was founded by Joe and James, two experienced tradesmen who met while working in framing. James focuses on plastering, and together, they bring years of hands-on experience to every job. Their goal was to fill a noticeable gap in the local market, where wind, hail, and cold weather often lead to frequent exterior and interior damage that many contractors overlook or rush through.
