What Is a Door Shim and What Purpose Does It Serve?

A door shim is a small piece of material, typically made from wood, plastic, or metal, that is used to adjust the fit of a door within its frame. Shims are inserted between the door frame and the wall or between the frame and the door itself to ensure proper alignment, stability, and functionality. They play a crucial role in making sure that doors open and close correctly, preventing issues such as sticking, gaps, or misalignment.

According to the National Association of Home Builders (NAHB), proper door installation is vital for aesthetics and functionality, and shims are essential tools in achieving this. They help maintain the structural integrity of the door and frame over time, ensuring they remain operable and efficient.

Key aspects of door shims include their material composition, thickness, and placement. Wooden shims are often preferred for their ease of use and ability to blend seamlessly with a wooden frame, while plastic and metal options provide durability and resistance to moisture.
