Why Does My Floor Feel Soft or Spongy?

A floor that feels soft, springy, or spongy can point to a problem with the flooring, underlayment, or subfloor. Moisture is one possibility, but not the only one.

A floor that feels soft, springy, or spongy can point to a problem with the flooring, underlayment, or subfloor. Moisture is one possibility, but not the only one.

Where is it happening?

A small soft area near a toilet, tub, dishwasher, sink, or exterior door deserves attention because water may be involved.

Did it appear suddenly?

A new soft spot after a leak is different from a floor that has always had some movement.

Check for moisture clues

Look for staining, swelling, musty odor, nearby leaks, and flooring separation.

Don't cover it with new flooring

New flooring won't repair a deteriorated or unstable subfloor.

When should I get help?

Have the area evaluated when the softness is increasing, moisture is present, flooring is sinking, the area creates a walking hazard, or structural support may be involved. Find Local Flooring Help
