Ever since we introduced the first low-maintenance residential siding in 1947, we've been raising the bar on appearance and performance.

Today, our advanced technology delivers stronger, more rigid siding systems that hug the home tighter, as well as rich, long-lasting colors and subtle textures that capture the authentic look of wood. Trim and accessories are available in a full range of styles and complementary colors for a completely custom look.

Whether you are remodeling a Victorian jewel or building a new home, whatever your budget, you will find that Castlerock's vinyl and steel siding offers the choice and value you're looking for.
