However, second floors cannot be repaired this way, due to the first floor ceiling. Your grandparents probably advised using talcum powder, liquid wax or powdered soap between the floorboards of that hardwood floor to stop it from squeaking. With new products like Squeeeeek No More, all of these old fashioned remedies can be forgotten. There is no need to lift up any carpet or floorboards and the task can be performed on top of the flooring. All it takes is a power drill and the provided hardware from the kit.
Squeaks occur when shrinks and gaps develop around different flooring elements.
For example, in most creaky floors, a nail that was used to fasten the floor has become loose and a squeak happens as a result of the nail rubbing on the sub floor. Or it's a possibility that wooden planks have loosened from the joist below them and are rubbing against one another. If possible, it is helpful to know how long the squeak in the floor has been around. Very old creaks in floors are harder to repair than newer ones. The sooner you can tend to a squeak, the better.
