Subfloor Problems

13 years ago

I recently removed a vinyl floor and luan in my kitchen in preparation for laying solid hardwood floor. The floor joists are 2X10's and a 3/4 in plywwod subfloor. I had numerous squeaks in the kitchen area over the years. I had put shims in the floor to try to stop the squeaks. Since I now have access to the plywood I put in deck screws 2 1/2 # 9's. This stopped the squeaks but now I have a new squeak in the area where I put the shims. My question is should I backout all the screws I put in and try to remove the shims? Some of the shims where put in with glue. Or should I quit worring about it and install the hardwood floor?

Thanks

I would back out all the screws, leave the shims in place. Go down below and apply construction adhesive along the top inside corners of the joists, where they meet the subfloor. Tool the adhesive into the corner with a gloved finger, so it gets forced into the little crack. Do this on both sides of each joist. Then fasten the subfloor screws down again.

The construction adhesive (liquid nails, et al.) is what builders use to keep floors from squeeking. The correct method is to apply a bead on top of each joist as the subfloor is laid and fastened. You can get some of the product between the joist and subfloor by following the instructions above.

Good luck!
