Hi, thanks for viewing my post.
I've laid down laminate flooring on a uneven subfloor.
its become spongy (all over) and we can hear the floorboard while walking on them. like a boom of air when stepped on.
I know now that an uneven floor would do something like this. but at the time I didn't. Problems with first time (house) buyers and being strapped for cash.
We cant afford to have it taken up and the subfloor fix.
what could be our solutions? We dont mind getting a expert round to do the job but im hoping he/she could do something like one of the following.
drill a whole and use expanding foam

or
drill all the boards and use a screw with removable head to secure it down.
I dont know what im talking about so please be kind, but would any of these ideas work?
any other advice would be amazing
thank you for your time.
