Why do my floors creak.

Once the adhesive hardens it ll prevent movement in the floor and stop the creaking noise. If there are voids the boards can flex into them and make creaking sounds as they rub together. A few trim screws inserted through the boards can help stop the squeak or you can place shims between the subfloor and the joist if accessible. Or if separating floor from subfloor is causing the creak drive two nails at opposite 45 degree angles into joists which you can locate with a stud finder.

The majority of sub flooring issues can be corrected by adding screws in the areas where the creaking is occurring. I have some squeaks in my floor that i have narrowed down to exposed nails coming through the plywood sub floor from the basement which is not finished. Nails rub on plywood when walking on floor and cause the squeak. As you walk across the floor boards rub against each other or slide against nail shafts to produce a cacophony of squeaks and creaks.

Occasionally if the floor joist are spaced two far apart to properly support the sheeting then floor creaking may occur. Rarely is this the case. Annoying floor squeaks common in many homes typically occur after the house has settled and flooring lumber has dried out and shrunk. Floor joists can occasionally twist warp bow or shrink.
