Remedying Sagging Floors in Your Home

Floors in your home are meant to provide a solid, level surface—any sagging or unevenness is cause for concern. Sagging floors not only detract from your home’s aesthetics but are also a red flag for underlying structural issues that necessitate expert attention. 

When your crawl space starts affecting your living area through problems like moisture buildup and pest infestation, it’s a signal to seek professional assistance. Mount Valley Foundation Services specializes in addressing these foundational challenges with solutions designed for longevity and effectiveness. Our proprietary SettleStop™ IntelliJack™ Crawl Space Jacks are crafted to give your floor joists—and your home—a dependable lift back to stability. 

This guide will walk you through the symptoms and causes of sagging floors, the importance of repairing them, and how the team at Mount Valley Foundation Services can restore safety and integrity to your floors. 

Identifying Sagging Floors 

Sagging floors may exhibit a noticeable downward arc or slope and often feel unstable underfoot, potentially bouncing or shifting as you move across them. This typically happens when the floor joists beneath the subfloor are compromised and no longer provide adequate support, hinting at a deeper structural problem within your home. 

Beyond the visible sag, other symptoms can include: 

In worst-case scenarios, the floors may even detach from their supporting walls or beams. Ignoring these warning signs can lead to worsening conditions, which is why professional evaluation and repair are imperative. 

What Causes Sagging Floors? 

Sagging floors can result from various factors, including one or several of the following: 

  • Moisture: Excessive moisture or water leakage in the crawl space can lead to the wooden structures absorbing water, causing rot, warping, and structural weakness. 
  • Pests: Termites and other wood-damaging insects can eat away at the integrity of floor joists and subfloors. 
  • Over-spanned Joists: Joists that are spaced too far apart may not provide sufficient support for the floor, leading to sagging. 
  • Installation Flaws: Incorrectly installed floor joists can lead to structural inadequacies. 
  • Foundation Movement: Shifts or settling in the foundation beneath the joists can result in misalignment and sagging. 
  • Natural Deterioration: Over time, the natural aging process can lead to the weakening of floor components. 

Early detection and professional rectification of the root cause are essential to effectively combat sagging floors. 

Can Sagging Floors Be Fixed? 

Absolutely, sagging floors can be repaired, but this task requires professional know-how and the right materials. Quick fixes or DIY attempts often do not address the fundamental issues and can sometimes be dangerous. 

Mount Valley Foundation Services offers comprehensive solutions that tackle not just the symptoms but the root causes of sagging floors, ensuring a secure and long-lasting result.
