Building Confidence Since 2003

Established in Austin, Texas, in 2003, SureSill revolutionizes the door and window installation industry with innovative and industry-leading flashing systems. Our inception was guided by our founder Mishko's unwavering dedication to mitigate the severe consequences of improper door and window installations. Drawing from 20 years of experience as a builder and mold litigation consultant, Mishko saw firsthand the potentially catastrophic damage, including costly mold build-up and risks to family health and home safety.

SureSill emerged to equip builders and installers with superior flashing systems. Beginning with a groundbreaking sill pan design, we broadened our portfolio to incorporate head and corner flashing. Our steadfast commitment to innovation, quality, and durability propels us to continually redefine industry standards.

Our innovative practices have led to the development of new installation methods, earning recognition and adoption by ASTM. We pride ourselves on offering products that not only comply with but exceed all building codes and ASTM standards. This commitment to excellence has attracted the endorsement of industry heavyweights like DuPont, Henkel, and Jeld-Wen. Our 10-year warranty underscores our unwavering dedication to quality and innovation.

We deliver superior, user-friendly, and cost-effective solutions to window and door manufacturers, builders, homeowners, and distributors. Our aim is to instill confidence in all our stakeholders, from distributors to end users. By reinforcing buildings against water damage, we are safeguarding not only the homes but also the families residing in them. At SureSill, we build confidence, one home at a time.
