How can I find the stud in the second floor( on the floor) to get rid of squeaky floor? thanks?

Question

I have a squeaky floor in my bedroom and I tried to screw it down to the stud. but apparenlty I cant allocate the stud properly. I was using the rule of 9" from the wall, then 16" between each stud... apparently it didnt work. I appreciate your help

Stud finder didnt help me:(

Answer 1

i use a stud finder, but everytime i turn it on it points to me.

The joist may be running in a different direction from what you think it is.... The hollow space between joists has a slightly lower pitch to the sound, and a very slightly longer duration, when tapped. I use my hammer, and start off by tapping in a circle around the squeak...when I notice a change in pitch, I tap in an X pattern to better locate the joist. The joist should be running thru the squeak (or just to one side of it, Ive often found, hehe). A number 6 trim head screw works well, when it is needed to shoot a screw thru the carpet....the head is small enough, it goes right thru. If the squeak is slightly off center of the joist, it may be necessary to run the screw in at an angle, to hit the joist.

Squeaks in a plywood subfloor are most commonly caused by the fastener coming loose, and allowing the plywood to ride up. You get the squeak when weight is applied, and the plywood slides down on the fastener (usually a nail, or staple). But another cause is wood rubbing on wood....this can be caused by several things, up to and including a problem with the floor joist itself.

Worst Case Scenario.... you can pull back the floor covering (and pad, if it is carpet), to actually see the sub-floor joints.

I don't know where you came up with this rule, but it makes absolutly no sense! Floor joists are laid out on 16" center, period! Look at the nailing pattern on your floor for the sub-flooring. It should be nailed on the floor joists. However if there has been a secondary flooring laid of the sub-floor you're gonna have to sesort to measuring 16" out from the wall and using a very thin drill bit, start looking for more than 1" of wood. Once you find the first joist, the rest are easy. Just measure 16" over

Answer 4

You can try a density stud finder.
If that doesent work i have used a tiny drill bit to look for solid wood by drilling a series of holes till i found it.

Answer 5

knock along the wall/floor

if it sounds hollow: no stud
if it doesn't sound hollow you've found it
