I have got a squeak in the first floor master bath. the subfloor is 3/4 t&g plywood and is covered with vinyl flooring. I’m not sure if there is a luan covering on the plywood. I can see the spot that squeaks from below in the basement although I cannot discern any movement. there is no water damage. it appears that when the house was built they may have been delayed slightly putting the subloor down because of repositioning as there are traces of adhesive a couple of inches over from the joists and I think that the adhesive may have skinned before they actually set them in their proper place. anyway, I really don’t want to rip up a perfectly good floor to screw down the subfloor and was wondering what your thoughts are on “toe screwing” the subfloor from below. this would involve carefully drilling a larger hole in the joist to allow the screw to pull the floor down rather than riding up on the screw. I have had limited success with this technique before but at this spot there is also a seam that runs traversely across the joists. what are you thoughts gang?

*Steve, My cure for this problem is to take a 2x2 with a healthy bead of good construction adhesive on the top and the side and attach it to the joint between the squeaky plywood and the joist. Run a few screws through the 2x2 and into the joist to hold it tightly in place until the adhesive sets up. This works every time!! Guaranteed !! Also very easy to do in your case... Use LOTS of adhesive. PL Premium is the best.....
*Gerry has the right idea....or if you don't want to to do that..take a couple of tubes of silicone and run/ force a bead alongside the joist / floor junction on both sides. ( we use silicone all the time now when laying floor, instead of construction adhesive. never have squeeks)
*I can see how using all silicone would help eliminate squeaking in the first place, as it stays more flexible....nothing to rub against= no squeak, but to stop a small section from moving while all the rest is stationary......I'd "stick" with the liquid nails. Ya need something that's gonna fill the void and harden up. Over fill, then stay off it a day or two. Jeff
*Steve, most often the squeak originates from a nail that is slighty projecting above the subfloor. The plywood is riding back and forth against that nail.You could grease the nail. But I wouldn't.You might try cutting the nail with a hacksaw, or sawzall before gluing the holy hell out of it. blue
*Thanks guys, I went ahead and glued n' screwed some 2x4's per G. LaLonde's recommendation and it worked great. there was no x braces between the joists, 3" drain running down the middle between the joists, so I nailed some blocking at the bottom to help stabilize the joists as well (hell, I needed an excuse to break out the new gun I just got anyway)thanks again, Steve
