Also to know is, Does Sistering floor joists work? Sistering joists means beefing them up with additional material. Doing so strengthens weak joists and can help straighten sagging joists. Framing lumber is the typical choice for sistering material, but engineered lumber products actually add more stiffness than dimensional lumber.
Subsequently, question is, How do I strengthen my floor joists? Fix bouncy floors by adding bridging, adding a layer of plywood or adding a wall or beam. We’ll show you three ways to stiffen up your bouncy floor—by adding bridging, installing plywood along the joists and adding a wall or beam under the floor. Any one of the three can solve your problem, depending on your situation.

It can be easy to overlap the new lumber with good lumber from the existing joist with just a few inches. By doing this you save lumber but do nothing to secure the pieces together. Overlapping the boards by two feet or better is best.
Is it OK to screw into floor joists?
The hole cannot be larger than one-third the depth of the joist, so the maximum hole size for a 2×12 joist (actual size 1-1/2 x 11-1/4 in.) is 3-3/4 in. You can drill the holes anywhere along the length of the joist (first photo).

Figure A: How Joists Work When weight is applied to a joist, the top edge goes into compression while the bottom edge goes into tension. Improperly sized or placed holes and notches weaken the joist, make it bouncy and saggy, and provide an easy place for it to crack and fail.
