Why do my floors feel bouncy?

A firm and level floor is a sign of a well-maintained home, but sometimes you might feel a bounce or springiness when walking. This isn’t just a trivial matter or a common feature of old houses; it could be a sign of deeper structural problems. 

At JES Foundation Repair, we specialize in addressing these challenges. We offer extensive crawl space repair services that target the fundamental reasons for bouncy floors, preventing further damage. 

Homeowners throughout the region have trusted us to repair and protect their homes for 30 years, and we are eager to help you, too. 

In this guide, we explore the phenomenon of bouncy floors, uncovering their causes and how our proprietary solutions effectively address them. 

What Are Bouncy Floors? 

Bouncy floors are characterized by noticeable flexing, bouncing, or sagging when you walk on them. This is often a sign of inadequate support from the floor joists and underlying structures, leading to the floor shifting under weight. 

This problem is commonly observed in upper levels of homes with crawl spaces. 

Other signs of bouncy floors include: 

While they might seem like a minor inconvenience initially, bouncy floors can indicate serious structural issues that worsen over time. It’s important to consult crawl space repair experts like JES Foundation Repair at the first sign of these problems. 

Causes of Bouncy Floors in Your Home 

Understanding bouncy floors requires examining their underlying causes, such as: 

  • Over Spanned Joists: Joists supporting floors above crawl spaces may be spaced too far apart or be too long, causing excess flexing. 
  • Inadequate Support: Insufficient support structures like poorly installed or shifted posts and beams can lead to bouncy floors. 
  • Weakened Joists: Factors like moisture, wood rot, pest damage, or general wear can weaken wooden floor joists. 
  • Heavy Loads: Excessive weight from furniture or appliances can overload the joists. 
  • Foundation Damage: Shifting or settling foundations can strain supports. 

Our professionals at JES Foundation Repair thoroughly inspect crawl spaces to identify these issues and provide effective repairs. 

Is It Possible to Fix Bouncy Floors? 

Yes, bouncy floors can be fixed. However, it’s important to address this problem comprehensively. DIY solutions and store-bought products often fail to tackle the root cause and can be unsafe to install. 

Our approach at JES Foundation Repair involves a complete home assessment to ensure a long-lasting fix. We conduct in-depth inspections to understand why your floors are bouncy, then create customized solutions to stabilize and potentially lift them. 

How We Fix Bouncy Floors

Encapsulate the Crawl Space 

The IntelliJack™ system is just one piece of our comprehensive crawl space solutions. To fully address the cause of bouncy floors, we fully encapsulate, waterproof, insulate, and dehumidify the crawl space, sealing out moisture and humidity.
