A question about floor joists

I would cut the old one out.

Multi tool or a flush cut blade on the sawzall to cut the nails. Use liquid nails on top of the new joist and screw it to the sub floor from the bottom. I use to work for a termite company and we did this every day.

What makes me crazy is the wording. Let me pass this on beacuse everyone here is saying it wrong.

You have one joist or you have 100 joist. There is NO joists. It is never plural.

And that ladys and gentlemen is your tip of the day.
