Sinking Floors

The brick pier foundations underneath your house provide stability and keep your floors level. As your house ages, so will the pier foundations and ground underneath it. They can shift or sink causing the floor inside your house to dip or bend inwards.


Your sunken floors may even separate from the bottom of your walls.


These gaps between the walls and the floors can create chilly drafts in the winter, increased humidity in the summer and provide an entry for unwelcome bugs and bacteria all year round.


Sunken floors are an indicator of structural issues in your home from a variety of subsidence factors that include –


  • Excessive moisture in the soil

  • Consistently dry, hot weather

  • Seismic activity or vibrations from heavy vehicles from nearby roads

  • Tree roots growing under the ground

  • Poorly prepared soil prior to construction


If you have sunken floors in your home, it’s time to get it inspected.
