What causes spongy floors? There are a couple of reasons:


If your foundation is built on expansive, clay-rich soil, those spongy spots in your floor might be caused by foundation settlement. When Charleston gets a decent rain, the clay in the dirt expands, pushing on your foundation. In the dry months, the dirt shrinks, pulling your foundation down. After some time, as the soil underneath your foundation repeats this cycle, your home will start to sink.

Your foundation may begin settling if the dirt it is based on isn’t sufficiently compacted. Over time, the soil will start to falter under your home’s weight and your foundation will start to settle.

And there’s more.


Spongy floors can also develop if your floor joists are too far apart. If the support columns and joists between your floor are over-spanned, your foundation cannot evenly support your floors. Soft spots may develop in your floors where there is less support due to time and wear.

There are more explanations.


Water damage, plumbing leaks, and South Carolina’s high humidity are no friends to wooden foundations and floors. Wood rot caused by excessive moisture can weaken the floor joists beneath your home and result in spongy floors.
