What Is Wood Rot?

Wood rot happens when wood deteriorates and weakens due to moisture, such as in the case of wet rot. This can be triggered by issues like leaking pipes, flooding, or excessive humidity. As the wood decays, it becomes structurally compromised and may eventually crumble. Wet or dry rot is particularly hazardous because it spreads rapidly and, if left untreated, can significantly undermine the structural integrity of your home.

Signs That You Have Wood Rot

There are a few signs that you should look out for if you suspect that your home has wood rot.

1. Soft or Spongy Texture

Wood affected by rot often becomes soft or spongy to the touch. You can press your finger into the surface or tap it with a tool to check for this change in texture.

2. Discoloration

Wood may darken or develop color changes, such as brown, yellow, or black patches. These discolorations often indicate fungal growth, which is a common cause of rot.

3. Foul Odor

Rotting wood emits a musty, earthy smell. This odor is produced by mold and fungi growing within the wood.

4. Visible Mold or Fungus

In some cases, you might see mold, mildew, or fungal growth on the surface of the wood. This is usually a sign that rot is underway.

5. Cracks or Splits

As the wood begins to deteriorate, it may develop cracks or splits. These can deepen over time, especially as the wood weakens from internal decay.

6. Presence of Insects

Wood rot can attract wood-destroying insects like termites or carpenter ants. If you see these insects or signs of their activity (like small holes or sawdust), it could indicate rot.

7. Crumbling or Powdery Wood

Severely rotted wood can start to crumble or turn into a fine powder when disturbed. This is often an indication that the rot has progressed significantly.
