Default What to do on subfloor before replacing carpet?

Hello all,

We are thinking of ripping up the carpet on our second floor and replacing with hardwood. My question is this: once the carpet is off, is there something you would recommend doing to the subfloor to reinforce it (before the contractors come in to place hardwood)? I remember reading a thread here where owners have added additional nails to the subfloor. If so, please recommend in detail what to do (type of nail, nail gun, where to nail, any pictures, etc.). Thanks a lot!

1&1/4" floor screws. Dump a bunch in where ever you hear squeaks and creaks.

Thanks xdarrylx. Do I need to be mindful of the joist positions, or is it ok to drive a screw in at random locations? Sorry, I don't know how the subfloor is supported in a modern home.

Screwing them down in random spots won't do much as you're not pulling the plywood down into anything. You should be able to follow the seams and simply add a bunch in between the existing nails/screws already so as many as possible hit the joists, helping pull the wood in and eliminate squeaks and creaks. You might not get them all (as some nails/screws might be rubbing against the joist but you can fix a good 90% or more). Good luck!

In my 1st house when I did the same thing (pulled old carpet), I emptied a 500 screws into our living room/hallway/dinette and it helped tremendously.

Like the previous posts - use deck screws. Never nails. It is the nails that make the floors squeak.

Any imperfections in the subfloor can lead to problems with your new carpet.
-Clean the floor thoroughly and remove the nails or staples that are left by the old carpet.
-Flatten the floor.
-Replace the damaged flooring.
