Flooring and Floor Noises in buildings

Antique wood floor (C) Daniel FriedmanFlooring and Floor Noises in buildings are most often due to construction details, less often due to potentially unsafe structural movement or damage such as movement due to rot or insect attack.

  • Creaky floorboards or stair treads are caused by movement of the floor board over the subflooring or over floor joist surfaces, particularly when someone walks across the loose flooring.

    Typical repair methods involve using screws, possibly glue, and stiffening plates affixed to the floor from below. If the floor is bouncy additional framing support may be required.

    A sneaky method for repairing loose floorboards from above can produce good results if there is n no access to the floor from below, by lifting an angled cut into the floorboard, driving a suitable screw, and gluing the cut back in place.

  • New floor and subfloor construction methods often employ a combination of structural adhesive (between the joist top and floor or subfloor underside) as well as mechanical fasteners to make a floor more rigid and less noisy.
  • Flooring may also be noisy because the supporting framing is more flexible than modern standards recommend.
  • Noisy flooring can often be improved or eliminated by the use of mechanical fasteners screwed into the flooring through joists from below.
