Squeaky flooring can be nerve wracking!  Of course it is usually  in a location where you walk everyday!  There is only one reason why floors squeak, groan or pop when walked on, movement.  When you stop the movement between surfaces, you stop the noise. The solution is simple, find the air spaces or broken glue bonds that allow movement.

  

Step 1.  Determine the source of the noise so we can design a fix.  Once this is determined choose the appropriate fix from below.

Fix 1.  If it is a gap between the subflooring and the supporting joist, the fix is to fill in the gap. Reference the drawing to see the placement of shims between the top of the floor joist and the sub-floor. Tap the shims in tight to keep the subflooring from moving when weight is applied.

 
 

Fix 2.  If the gap between floor joist and sub-floor is large, fastening a sister joist as pictured will solve the problem.  You can use any size sister joist that is 2x4 or larger. Place construction adhesive on top of sister joist and put upward pressure during installation.  Bolt or lag screw to existing joist.

 

 

 

Fix 3.   If Loose hardwood flooring is squeaking it can usually be stopped by pulling it down tight to the sub-flooring.  The best way to do this is to install screws from underneath, pulling the flooring down and securing it.  Make sure the screws are not too long.  Drywall screws come in 1 1/4" length which would be ideal if your thickness is 1 1/2". 

 

 

Fix 4.  When it is not possible to reach loose floor boards from below, you can face nail from above and cover the holes with putty. As the drawing shows we recommend you drill pilot holes and angle your nails for greater holding power. With pilot holes drilled you could consider using square drive finishing screws for even greater holding power.

Remember...your goal is to stop movement, which is the cause of the noise.
