Many homeowners face the challenge of how to repair a warped hardwood flooring especially after water damage from a leaking roof, plumbing pipe or a flood in the home. Some homeowners opt to leave their wood floorings unsealed to try to attain a rustic look, which leaves the wood open to moisture absorption. Sealed wood provides the floorings with a layer of protection from damage. If the hardwood flooring is not covered by a sealer, they will warp much more quickly and easily than a sealed flooring. Once wood absorbs moisture, it becomes swollen resulting in twisting and warping.


Wood floorings with a Little Warp

Wet a thick towel or blanket in hot water and wring out the excess, so the blanket or towel is wet, but no longer drips.

Lay the blanket or towel over the warped flooringboards.

Place heavy weights such as cinder block, bricks, tall stack of books or even a large pot of water directly on top of the warped boards.

Allow the weights to stay in place for two to three days or until until the warp is wet and the moisture has permeated into the flooring board.

Lay a large dry towel or old blanket over the warped area and place the weights back on top of the boards for another two to three day hours or until the warp flattens out and the boards are flush with the rest of the wood flooring.

Apply paste flooring wax over the section you just repaired along with the rest of the flooring. The paste floor wax creates a seal that protects the wood from water and helps to avoid future warps.

If you are very ambitious,seal the entire wood floor with polyurethane.


Wood Floors with a Bigger Warp

Place wet blanket or towel over the warped section of the hardwood floor and place weight on it for one day.

Insert a drill bit slightly slimmer than the existing floor nails or screws.

Drill holes every 3 to 4 inches throughout the warped board, straight through into the floor joists.

Align long screws to the pilot holes and sink the screws through the warped floor board into the flooring joists.

Fill in the holes from the screw heads with wood putty. Allow the wood putty to dry.

Sand the wood putty repair with 180-grit sandpaper to make it smooth and even with the existing floor.

Paint over repairs with a liquid furniture scratch cover or gel wood stain.


After the wood stain or furniture  scratch cover dries, apply a coat of paste floor wax over the surface.
