Question: 1 / 400

Before installing a stair, what should be ensured regarding the stringers?

They are level and centered

Ensuring that the stringers are level and centered is crucial for the proper installation of stairs. Stringers serve as the structural backbone of a staircase, providing support for the treads and risers. If the stringers are not level, it can result in uneven treads which may create trip hazards and an uncomfortable climb. Centering is important to maintain symmetry along the width of the staircase, making sure that the load is evenly distributed and that the stair configuration is visually appealing and functional.

While other aspects, such as aesthetics or material choice, can be considered at different stages of the project, achieving a level and centered stringer setup is fundamental to the safety and usability of the staircase. This structural integrity is key to ensuring that the stairs are safe for regular use and meet building codes.
