Reinforce Floors With Sistering Joist Technique

Sistering a floor joist involves adding a new joist alongside an existing one to reinforce it. This technique is used to increase the load-bearing capacity of a floor when additional weight or structural support is needed. The process typically involves measuring and cutting the sistering joist, attaching it to the existing joist using joist hangers and fasteners, and securing it with adhesive for added strength.
