Do You Need Underlay on Stair Risers? Uncovering the Role of Underlay in Staircase Comfort and Durability

While underlay is primarily associated with stair treads, its application on risers is a subject of debate. While not strictly mandatory according to most building codes, underlay on stair risers can offer several benefits, particularly in terms of comfort, noise reduction, and longevity of the staircase. However, the decision to use underlay on risers often involves weighing these advantages against potential drawbacks and aesthetic considerations.

The Case for Underlay on Stair Risers

  • Enhanced Comfort: Underlay adds a layer of cushioning beneath the carpet, making the stairs feel softer and more comfortable underfoot, particularly when descending barefoot or in socks.
  • Noise Reduction: Underlay acts as a sound barrier, absorbing impact noise and reducing the transmission of footsteps throughout the house. This can be particularly beneficial in multi-story homes or spaces where noise control is a concern.
  • Improved Durability: Underlay helps to protect the carpet from wear and tear, especially in high-traffic areas like stairs. It acts as a buffer, absorbing the impact of foot traffic and preventing the carpet fibers from being crushed or flattened.
  • Moisture Barrier: In certain situations, especially in basements or areas prone to moisture, underlay can provide an additional layer of protection against dampness, preventing mold and mildew growth.

Potential Drawbacks and Considerations

  • Bulk and Fit: Underlay adds thickness to the risers, which might affect the overall fit and appearance of the staircase, especially if the risers are already narrow or the carpet is thick.
  • Tripping Hazard: If not properly installed and secured, underlay can create a tripping hazard, particularly at the edge of the tread where it meets the riser.
  • Aesthetics: Depending on the type of underlay and carpet used, the added thickness on the risers might be noticeable and affect the overall visual appeal of the staircase.
  • Cost: Adding underlay to risers increases the overall material and installation costs of the staircase project.

Making an Informed Decision

  • Foot Traffic and Comfort: Consider the level of foot traffic on the stairs and the desired level of comfort. High-traffic areas or homes with young children or elderly residents might benefit more from the added cushioning and noise reduction of underlay on risers.
  • Carpet Type and Thickness: The type and thickness of the carpet also influence the need for underlay on risers. Thicker carpets might already provide sufficient cushioning, while thinner carpets might benefit from the additional layer of underlay.
  • Budget and Aesthetics: Weigh the cost and potential aesthetic impact of underlay on risers against the desired benefits.

Conclusion

While underlay on stair risers is not mandatory, it offers several advantages in terms of comfort, noise reduction, and durability. However, it is essential to weigh these benefits against potential drawbacks and consider the specific context of your staircase project before making a decision. Consulting with a professional installer or flooring specialist can provide valuable insights and guidance based on your individual needs and preferences.
