Demystifying the Stair Skirt Board: Function, Materials & More
Brief Summary
A stair skirt board, sometimes also called a stringer board, is a vertical board that runs along the wall side of a staircase, typically on the closed side where the treads and risers meet the wall. It serves both aesthetic and functional purposes, enhancing the visual appeal of the staircase while protecting the wall and providing a finished look.

Function and Placement of Skirt Boards
- Aesthetic Enhancement: Skirt boards contribute significantly to the overall visual appeal of the staircase. They conceal the rough edges of the stringers (the structural support boards) and the wall framing, creating a clean and finished appearance. They can be customized with decorative moldings or profiles to complement various architectural styles.
- Wall Protection: The skirt board acts as a barrier between the staircase and the wall, protecting the wall surface from scuffs, scratches, and other damage caused by foot traffic or moving objects.
- Ease of Cleaning: The smooth surface of the skirt board is easier to clean than the textured surface of a wall, simplifying maintenance, especially in high-traffic areas.
- Concealment of Gaps: In some cases, the skirt board can help to conceal any gaps or imperfections between the treads and risers, creating a more seamless and polished look.
Material and Construction
- Wood: Skirt boards are commonly made from wood, often matching the species and finish of the treads or risers for a cohesive appearance. They can also be painted or stained to create a contrasting accent.
- Edge Glued Construction: Many skirt boards are manufactured using edge-glued lumber, which involves joining multiple narrow boards together to create a wider panel. This technique enhances the board’s stability and reduces the likelihood of warping or cupping.
- Sanded and Ready to Finish: Most commercially available skirt boards are pre-sanded, making them ready for staining or painting to match your desired aesthetic.
Building Codes and Trends
- Not Structurally Required: Skirt boards are not typically mandatory under U.S. building codes. However, they are highly recommended for their aesthetic and protective benefits.
- Fire Safety: In certain occupancies or building types, fire codes may require the use of fire-rated materials for skirt boards, especially in egress stairways.
- Accessibility: If the staircase is part of an accessible route, the skirt board should not create any protruding obstacles that could impede wheelchair users or those with mobility impairments.
- Modern Minimalism: While skirt boards are a staple in traditional staircase design, modern aesthetics often favor a cleaner look with minimal or no trim, leaving the stringers exposed.
Conclusion
A stair skirt board is a valuable addition to any staircase, providing aesthetic enhancement, wall protection, and ease of cleaning. While not structurally mandatory, it significantly contributes to the finished appearance and longevity of the staircase. By understanding its purpose and design considerations, you can choose the right skirt board to complement your home’s style and ensure a beautiful and functional staircase for years to come.
