Sills

Sills are the front line of defense against moisture at any exterior door opening. A well-designed sill not only ensures water drains away from the building envelope, but also provides a secure foundation for the door frame above.

We offer wood, aluminum, and composite sill options in a variety of heights, slopes, and finishes. Many come with replaceable cap inserts or integrated thermal breaks to enhance energy performance and ease future maintenance. Low-profile designs allow for seamless interior transitions, while raised sills offer extra weather protection.

We work closely with clients to ensure sill profiles align with both door hardware and flooring conditions. Whether you’re dealing with a site-built jamb or a prehung unit, we help you dial in the sill spec so water stays out—and durability stays in.
