My recently installed bamboo floors are squeaking. Can you tell me why?

Subfloor is wood slab. Subfloor was securly nailed and a water barrier cover was installed before floors were installed. These are floating floors

Apossible reason is that if new fasteners were added as a part of the sub-floor prep for the new floor, a new nail could have caught a joist edge, split it and not be in full contact with the wood.

  • As you walk across the floor, the boards move against each other or slide against nail shafts to produce the squeaks.
  • If this is the case, the new flooring could be disassembled and the fastener removed or secured.

Also squeaks and gaps can result from too soft an underlayment, an un-flat subfloor or improper acclimation - taking the new flooring from a semi-conditioned storage area and installing it without waiting for the flooring to adjust to the humidity levels in your home.

Additionally, be sure there is a perimeter expansion gap around the room and any pipe penetrations, such as a floor radiator would require. Some manufacturers require the expansion gap width match the flooring thickness.
