If you find joists in the house that have notches cut out of it on top
but with no pipes going through it, would it be a good idea to drop in,
screw in and glue wood pieces cut to size to fill the notches?

I am under the amateur assumption that a 2x10 floor joist holding a load
will be under tension at is bottom side and under compression on the top
side.

So would filling the 1" cube notches on top of the 2x10 joists restore
the joist in anyway to 100% of its load carrying capability?

Thanks
