What Are Over Spanned Floor Joists? 

Over spanned floor joists happen when the horizontal beams, or joists, that uphold your floor are too widely spaced or lack the strength to bear the floor’s weight, jeopardizing your floor’s structural integrity. 

These insufficiently supported joists weaken the floor system, leading to several issues, including: 

Ensuring a proper joist span is vital to keeping your floors stable, secure, and able to bear the weight of your household and activities. Quick intervention is needed to correct this issue to prevent further complications. 

What Causes Over Spanned Floor Joists? 

Numerous factors can lead to the issue of over spanned floor joists, such as: 

  • Moisture: Humidity and wetness in crawl spaces can distort and weaken wooden joists. 
  • Pests: Insects like ants or termites can consume joist materials, reducing their structural capacity. 
  • Foundation Shifts: Alterations or damage in the foundation can distribute uneven stress across the joists. 
  • Building Errors: Sometimes, a house might be built with joists that are too far apart, resulting in insufficient support. 
  • Aging: Over time, floors and joists may degrade without adequate extra support. 

Identifying and repairing these causes promptly is important to prevent lasting harm and ensure your home’s structural resilience. Routine inspections and upkeep can spot issues early, potentially saving significant expense and effort.
