What Are Over Spanned Floor Joists? 

Over spanned floor joists occur when the horizontal lumber beams that support your main floor—known as joists—are spaced too far apart or are not strong enough to carry the load. This compromises the structural integrity of the floor. 

Over spanned floor joists become inadequate, weakening the floor structure and causing a myriad of potential problems, including: 

A proper joist span ensures that your floors remain even, firm, and capable of supporting the weight of your home, furniture, and daily activities. It is essential to address this problem promptly to prevent further damage and ensure the safety and stability of your home. 

What Causes Over Spanned Floor Joists? 

There are several potential causes of over spanned floor joists, including: 

  • Water: Crawl space moisture, humidity, and dampness can warp wooden joists over time and lead to sagging. 
  • Pest Infestations: Pests like termites can eat away joist material, weakening their support. 
  • Foundation Damage: Foundation settling, shifting, or damage spreads uneven stress across joists. 
  • Construction Issues: In some cases, joists may be spaced too far apart during the home’s initial construction, leading to inadequate support.  
  • Age: The floor and joists can weaken over time if they don’t have enough supplemental support. 

It is crucial to promptly identify and address these causes to prevent long-term damage and ensure the structural integrity of your home. Regular inspections and maintenance can help identify potential issues before they become severe, saving you time and money in the long run. 

Can You Fix Over Spanned Floor Joists? 

Yes, over spanned floor joists can be fixed, and it is crucial to address this issue promptly to prevent further damage and ensure the safety and stability of your home.  

However, piecemeal fixes like sistering joists or adding light-duty posts often fail to comprehensively stabilize a weakened floor. Implementing DIY repairs and products from big-box stores can also be dangerous and expensive.  

Fixing over spanned floor joists properly requires a comprehensive approach, ensuring that the entire structure is supported adequately.
