Wood Rot in Sub-Floor

Just sister some new ones in. Do you know what I mean when I say sister?

Good advice above!

I once removed a mudset on mortar bed ceramic and had the top 1.5" missing due to the mud layer. I single sistered each joist with one approved for the span (the old ones were oversized to allow for the top trimming). Passed more than one home inspection with flying colors.

I think that you mean just add another 2x4 on the side of the rooted boards, right? Do we need to treat the rot?

Is it dry rot or from moisture getting in? It should dry out just being exposed. If you're concerned take a chisel and remove it.

Yes that's what I mean when I say sister. You might want to screw the 2 X in instead of nailing. Nailing can cause cracks or drywall nails to show up on other side.

bzzt. wrong. I've 'never' seen a 2X4 floor joist.

If you do not understand loads and beams, sister them with the same size as the existing member.

If the joists are 2x8 use a 2x8. You may waste a little wood but you can't go wrong doing it this way.

Won't say that using screws is necessary but you might want to add not to use drywall screws. Very brittle, thin necks and can snap over time with natural movement. Can also snap with torque on install.
