Floor Squeak

[BJ42LX]

I'm installing hardwood in my foyer and kitchen. All the old flooring is out and I'm ready to start laying the hardwood.

I've got a serious squeak at the landing of the stairs in the front hall right where you step off.

I ran 2" screws through the sub-floor into the joists every 4" with pre-drilling and it still squeaks. There are no seams in the sub-floor in that area; it's in the middle of a sheet of plywood.

I have a basement so there's access to the joist area. I tried driving shims in between the joists and sub-floor but there's construction adhesive preventing that.

What is causing this and how can I fix it before I lay the hardwood?

is the squeak from a heating duct or cold air return rubbing on joist ?

LOL, more screws isn't better as it will split the joist. Go downstairs and get your kids or wife to walk around so you can ballpark the noise. Make sure the screws are backed out and from below, drive in a nail puller and squeeze in as much glue as you can.

Cobbler, no duct work in the area. It's definitely wood on wood.

Make sure the screws are backed out and from below, drive in a nail puller and squeeze in as much glue as you can.

Well, I just finished trying this. I backed out all the screws in the area. From the basement I used my screw jack to put pressure on the sub-floor right at the joist junction until I could see/hear some movement.

I put some Gorilla Glue in a syringe and just mashed it in the joint. I used a full two ounces of glue (all I had on hand). Then I went back upstairs and ran the screws back down.

I used Gorilla Glue over wood glue because it expands as it cures.

Initial impression is it is quieter than before, but still not perfect. Tomorrow I will check it again and try to make some more spot touch-ups. I may even drill some small holes down from the top an inject glue that way.

If it's plywood, it is possible the plywood has delaminated in the high traffic area. That will make a crackly squeak when walked on.

Maybe you can add a joist or 2 to stiffen the landing if all else fails.

And a few fun reasons why you need to be sure you don't have any squeaks!!

Maybe a spammer or manufacturer's rep.

I have had squeaks from the nails in bottom wall plates as the sub floor flexes. Some of these I solved by pounding shims between the subfloor and plate. Others I cut holes from below and screwed upward into sill plate. Still others I pulled base molding off, screwed down thru plate.
