We are going to recarpet upstairs rooms in our home. The floors are very sqeaky and I want to try to fix this before the new carpet goes down. There's no access to the flooring from below and I think the floors are squeaking where the edges of the particle board panels rub against each other.
Is it mainly a matter of finding the squeaks and putting new or additional screws through the particle board to fix them firmly again to the joists? Is there any way I can use adhesive to improve the fix? I am wondering if I could 'stitch' the edge joins in the boards by cutting or routing a series of slots at 90 degrees to the joint and gluing in 'biscuits' to firm up the joins.
I would be grateful for advice or comments on all this.
Cheers
Craig
