Since 1991, Masterpiece Leaded Windows has perfected the art while preserving the integrity by using genuine lead, premium glass and custom construction methods. A home or a model featuring leaded glass windows not only creates curb appeal, but also an aura of refined elegance and taste. Leaded glass can be used wherever you want to make a dramatic statement - in fixed and sliding windows of every size and shape, sliding and interior doors, and cabinets.
