Install Additional Stringer Reinforcements — Reinforce Stair Stringers and Treads
Part of project
How to Reduce Noise from Stairs and Upstairs Floors · Step 6 of 7
In this video
Beyond the basic tread/riser connections, consider adding horizontal reinforcement between the main stringers. Cut rectangular or shaped pieces of pressure-treated plywood or 1x lumber to fit snugly between the stringers, underneath the treads or behind the risers. These can be simple rectangular pieces or custom-shaped to follow the stair angle. Secure these reinforcements with exterior-grade screws or bolts, as shown in the video's more extensive 'new stringer' examples. This creates a stronger, more rigid structure for the new treads to rest upon.
