Over Spanned Floor Joists 

Sagging, tilting, and bouncing floors pose a safety risk and create a significant inconvenience. These issues are attributed to over spanned floor joists in the crawl space. If you notice these flooring problems, it is crucial to seek professional inspection and repair. 

Securing your home’s structural integrity depends on addressing floor joist issues. Baker’s Waterproofing specializes in providing top-tier crawl space repair solutions, including SettleStop™ IntelliJack™ Crawl Space Jacks, specifically designed for over-spanned floor joists, ensuring your living area’s stability.  

This page offers insights into over spanned floor joists, including causes, solutions, and why Baker’s Waterproofing is your reliable choice for crawl space repair in Pennsylvania and West Virginia. 

What Are Over Spanned Floor Joists? 

Floor joists become over spanned when they are spaced too far apart or lack the necessary strength to support the weight of the floor. This over spanning weakens the structural integrity of the floor, potentially resulting in various problems.  

It’s crucial to address over spanned joists to prevent further damage. Additional signs of joist damage may include: 

Maintaining an appropriate joist span is vital for upholding level and robust floors capable of supporting the weight of your home, furniture, and daily activities. Tackling this concern is imperative to avert further damage and uphold the safety and stability of your home. 

What Causes Over Spanned Floor Joists? 

Over spanned floor joists are caused by various factors, such as: 

  • Moisture in the Crawl Space: Excessive crawl space humidity, dampness, and moisture can gradually distort wooden joists, resulting in sagging. 
  • Pest Infestations: Pests, such as termites, can consume joist material, weakening their support. 
  • Foundation Settling: When the foundation settles, shifts, or incurs damage, it places uneven stress on the joists. 
  • Construction Flaws: Inadequate joist spacing during the initial home construction can result in insufficient support. 
  • Natural Aging: With time, the floor and joists may weaken in the absence of necessary supplemental support. 

Addressing these factors prevents additional damage and preserves your home’s structural integrity. Routine inspections and maintenance serve as proactive steps, identifying potential issues before they intensify, saving you significant time and money in the long run. 

Can You Fix Over Spanned Floor Joists? 

Yes, over spanned floor joists can be fixed. It’s vital to address this matter promptly to prevent additional damage and ensure the safety and stability of your home. 

Makeshift solutions like sistering joists or adding light-duty posts often fall short of fully stabilizing a weakened floor. DIY repairs and products from big-box stores can also pose risks and incur significant expenses. 

Effectively addressing over-spanned floor joists requires a comprehensive strategy that ensures adequate support for the entire structure. Baker’s Waterproofing provides customized solutions to stabilize, support, and shield against additional damage, safeguarding the long-term integrity of your home.
