In the never ending project of 'redecorating' one of the kids' rooms, we are removing carpet and putting down a nice, durable laminate flooring.
After removing the carpet and pad, we've found yet another amazing feat the builder of the house has accomplished. Our floors in our eleven year old house have squeaked in certain spots. It just so happens that the worst case is in the room we are putting a new floor down in.
The cause of the squeak is due to the fact the builder, while laying the sub floor, put the non-tongue-n-groove joints over the space between the joists. The joints run parallel to the joists. The root of the squeaking is the two edges of the sub floor rubbing together when you walk over it.
I am sure there is a safe, non-destructive, simple solution for this. Several ideas come to mind, but I'd like to hear what others have tried and found successful before I wander into unknown territory. One important point is that I can not get under the floor to run a 2x6 under the joint.
consider cutting out the 'joint' and replacing the part you cut out.
cut to the centre of two joists, glue and screw it.
actually, depending on the code requirements in your area, you may not be able to cut a single joist bay, so plan on cutting out 2 or more bays. I know that we never are allowed a single joist span here.
