How to Repair Swollen Laminate Flooring

  • First, inspect carefully the area that is swollen. Walk on the floor to examine any bubble present. If the bubbles are in one board, it means the board is already damaged and needs to be taken away. If you discover a bubble at the center of the flooring seam during inspection, it is an indication that there is no adequate expansion gap, forcing the boards to squeeze and swell on seams.
  • Remove the wall molding near the damaged laminate board with air bubbles.
  • Carefully remove the mold with a screwdriver and hammer to avoid wrecking the laminate floor molding. After removing the wall mold, remove the laminate board one by one until you get to the damaged board.
  • Slide the laminate floorboard with care from the locking mechanism, with the connecting board. If the bubbling resulted from inadequate expansion gap, you just have to fix the floor by easing the board’s tension.
  • Check the space between the wall and board at ensure it is about quarter to half of an inch. Fix it by cutting the board close to the wall.
  • Replace the damaged laminate floor with a new matching laminate floorboard. Put the tongue of the board into the groove of the next board.
  • In the event of the peaked board, you just need to place a weigh on top of the peaked board after creating adequate space. This would allow the floor to settle without any other intervention.
  • Put back the other undamaged floorboards in their initial place. Check your floor carefully to make sure there are sufficient expansion and contraction gaps on your laminate floor.
  • Make sure the newly installed plank board corresponds with the other planks to avoid color mismatch on your flooring.
