After spending money on flooring that are supposed to be perfectly flat, nothing is more annoying than stumbling over a bump in your beautiful hardwood flooring. Now what?

The procedure for fixing a warped wood floor really depends on the size of the bump. These tips are intended to help bumps of all sizes; however, a professional flooring contractor may be necessary for larger warps.

1. Fixing A Tiny Warp

If your wood is still rather pliable (like a solid wood), try wetting the area and placing a heavy object, like a cinderblock, on top. Leave it there for a few days and check to see if the warp is gone. If the warp is still there, you may have a bigger problem on your hands.

2. Sanding

If you know that the source of your warping comes from humidity changes or a water spill and not an underlying leak, then sanding the solid wood floor might be a good option. This requires an aggressive sanding technique that may cost a floor up to ¼ inch of its thickness.

3. A Replacement Job

If your warp is on the medium to large scale, you may have to do a replacement job. Carefully remove the warped plank and fix any underlying issues that may have been caused by a water leak. Replace it with a new plank of the same species, color, and size. Nail down and secure the wood boards using the same installation technique.

To avoid warped floors, choosing a laminate or engineered wood floor might be a better option over solid wood. Solid woods expand and contract with humidity changes and water leaks, affecting the shape of your boards. Laminate and engineered woods are manufactured to resist humidity changes, leaving them the same size forever. And of course, be sure to investigate any and all reasons why your floor might be warped. A water leak may lead to mold damage under your floors and you may not realize it.
