What is the Jamsill Guard® – why use it?

Jamsill Guard® is an adjustable sill pan flashing designed to prevent water damage from window and door leaks. Made from quality, high impact ABS plastics, Jamsill Guard® will not deteriorate or corrode over time. Jamsill Guard’s simple design is inexpensive, easy to install, and more “user friendly” than comparable products on the market. Our multi-piece telescoping design allows on-site adjustablility to fit all rough openings and features sloped weep areas to help evacuate moisture to the exterior of the structure. Jamsill Guard® is bonded together in the field using PVC cement, creating a one-piece sill pan flashing beneath your door or window.
