AAmerican Seamless Siding is a family-owned business that serves Missoula, Butte, Kalispell, and all the surrounding communities in the western Montana region. We specialize in exterior home remodeling projects, including the expert installation of seamless metal siding, roofs, gutters, replacement windows, and more. Our company was founded by David Khoury, an industry veteran with over four decades of experience in the siding business, and in the late 1990’s, we proudly became a franchise of ABC Seamless, a leading home improvement company that homeowners across the country have relied on since 1978. In 2003, the company was acquired by David’s son Damian, a skilled craftsman who has worked by his dad’s side for many years, improving homes throughout the region.
