Laminate, a synthetic flooring product, is often installed in homes because of its ease of use, resiliency and durability. Although laminate floors generally last for many years without problems, they may be prone to annoying creaks and squeaks in older homes. According to This Old House, floor creaks usually occur as floors begin to shift, settle, dry out or shrink—causing loose floorboards to rub against nail shafts, subflooring or other floorboards. Stopping floorboards from moving can eliminate the creak.
Apply a small amount of talcum powder between the creaky floorboards. Lubricating the floorboards stops creaking when boards rubbing together. Liquid graphite or floor oil may also be used as a lubricant.
Walk across the creaky floor and have someone listen below in a basement or crawl space to determine the location of the creaking.
Coat a thin wood shim with a generous amount of carpenter's glue. Wood shims are wedge-shaped pieces of wood typically used to level surfaces.
Tap the wood shim into the gap between the floor joist and subfloor, using a hammer. Tap it in just enough to fill the space above the floor joist without raising the floor.
Squeeze a generous amount of construction adhesive along the floor joists on both sides of the creaky floorboard. The adhesive must seep into the seams.
Hammer a 1 1/4-inch drywall screw at an angle to drive it up through the floor joist and wooden shim, straight into the subfloor. According to This Old House, the drywall screw provides extra support for the wood shim.
