Replacing Plywood SubFloor ...

we're renovating (go figure) ... and in pulling up the flooring (laminate, linoleum, you name it ... I've noticed several places where there's water damage to the plywood subfloor. not to mention the smell ... (1969 built home).

was just wondering about replacing the subfloor ... does the thickness of plywood differ that much? when would you use 1/2", 3/4" and 5/8" ? should I use tongue & groove? I'll definitely glue & screw - can't stand squeaks ... but was just wondering when you use which thickness.

any info would be great. thanks!

Ayuh,... You've got to figure out the Final height you want,+ then build up to it...

Subfloor + underlayment + flooring should equal the height necessary to match whatever is surrounding the area you're workin' on...

Use 3/4" t&g for your subfloor, glued and screwed.
What we've got here is... failure to communicate. Some men you just can't reach. So you get what we had here last week, which is the way he wants it... well, he gets it.

Replacing Plywood SubFloor ...

thanks for the info - I guess I thought the thicknesses were for different applications ...

i.e. if the joists were 12" oc you can use something thinner (1/2") or if the joists were 16" oc you should use 3/4" ... or if you were going to apply tile, hardwood, etc blah blah blah.

thanks for the info.
