A sill plate (also called a sole plate, or simply a “sill”) is the bottom piece of wall structure where wall studs are attached. They are typically anchored to the foundation and serve as a very important component of all houses. If the sills become damaged or rotten, you can end up with problems like sagging floors. Sill plate failure can be caused by a number of factors, but a problem like this is typically more common in older homes.

After years of wear and tear through the seasons in Indiana, sill plates can succumb to wood rot usually caused by the following three factors:

  • Humidity – Over time, moisture and heat contribute to the rotting of sill plates, often requiring them to be replaced by a foundation repair specialist.
  • Termites – These insects cause problems throughout the United States, including Indiana and Illinois and have been known to wreak havoc if left unchecked.
  • Other insects – If it’s not termites, it could be carpenter ants. While perhaps not as well known, carpenter ants can cause just as much damage to wood structures in a home as termites do.

If you notice issues with sagging floors, or discover you have an insect problem, it might be time to call in the experts.
