Why Do My Floors Creak

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.

Why do my floors creak.

Occasionally if the floor joist are spaced two far apart to properly support the sheeting then floor creaking may occur. 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. Creaks coming from wood floors happen for a number of reasons from loose nails to separation from the subfloor. Then fill the holes with wood filler.

When you glue a hardwood floor to concrete the subfloor must be completely level. Nails rub on plywood when walking on floor and cause the squeak. Screws will normally do a much better job of holding the. If there are voids the boards can flex into them and make creaking sounds as they rub together.

Rarely is this the case. Once the adhesive hardens it ll prevent movement in the floor and stop the creaking noise. As you walk across the floor boards rub against each other or slide against nail shafts to produce a cacophony of squeaks and creaks. 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.

Nail a board along a warped joist. Annoying floor squeaks common in many homes typically occur after the house has settled and flooring lumber has dried out and shrunk.
