How to fix a squeaky floor under linoleum?

You have to go in the basement, have someone stand on the squeaky spot so you can find it's location in the basement, then put a wood screw or 2 in it. The screws need to be long enough to screw into the cross sections that supports the floor boards.

I actually saw this on This Old House one time. They went down to the basement, put great big screws in the underside of the floor, and somehow brought all the boards together to straighten it out. Maybe go check their website & put in a search

This may be a two-person job. One person goes to the basement and the other walks on floor and yells out when he hears the squeak. You need to identify where the squeaks are exactly. Once squeaks are located, You will put some carpenter's glue on a thin wooden shim and gently tap it between the joists and the sub-floor. I hope this helps you.

The reason for this, is that the original floor was put down with nails. If they would have used screws, it wouldn't be doing this. Whatever area, is able to get at, lift up the rug, or flooring, and see if you can use a screw in place with the nail. This will truly help you, greatly. Best wishes, J.

Judy has the right idea exactly, screws are always better to use then nails! But as long as you can get to the underside of your flooring by way of your basement. You can add a block of wood glued and screwed to your floor Joice leaving a 1/8 “ or so gap from the underside of your flooring. You can also predrill holes in the block that will allow you to screw up into your flooring before adding this block to your floor joice! Then make sure the screws you use are not too long that you’ll screw thru your flooring upstairs. If you use 2”x2” blocks a 2 1/2 inch Sheetrock screw should be plenty long enough. Be careful not to countersink your screw into the block too far or you might find it sticking thru your flooring upstairs! I have done this many times on squeaky floors and it has never failed me! You can glue to the floor Joice and the top of the block where it will meet the floor, long as you’re quick and don’t allow glue to dry too much before adding your screws thru the block into your flooring from the underside! Again as Aljosier mentioned, if your not sure where your squeak is from your basemen? Another person can make it easier to find that perfect spot to add a block. But if you don’t have any help? Use long as blocks as you can attached to your floor juices and just add several screws up into your flooring from underneath and you’ll still get that squeekto go away! Best of luck
