SureSill™, Ltd. was founded in Austin, Texas in 2003 with a commitment to developing and manufacturing a superior flashing system for doors and windows. Our Sloped Sill Pan™ was immediately called “The Most Advanced Product”, “Best Practice”, “The Cadillac of Sill Pans.” Our HeadFlash™ was called “The Ideal Drip Cap”, and HeadFlash-Flex™ was called a “Unique Product”, and won a national Cool Product Award.

Today SureSill™ products follow that same commitment to superior quality. Our mission is simple: SureSill™ provides technically superior, user friendly and cost effective products and services, to assist window and door manufactures, builders, homeowners, and distributors in their work and their leadership in industry. SureSill™ products are designed to increase customer satisfaction from the distributor to end user.

The SureSill Integrated Flashing System for Windows and Doors™ is the superior flashing system used by contractors, window and door manufactures, and DIY customers. Our other innovative products are used everyday across the United States and Canada in window and door installation. Protecting the investments of consumers is at the heart of what we do. We believe in Building Confidence.
