Floor Gaps

Have you noticed mysterious drafts or cold spots in your home? Or perhaps there are visible gaps between floors and walls that allow dirt and pests to sneak in. These seemingly small issues can lead to much larger problems if left unaddressed. 

Floor gaps indicate that your foundation may be settling unevenly or sinking, compromising your home’s structural integrity. Thankfully, the foundation repair experts at Basement Authority of West Virginia can diagnose the underlying cause and implement solutions to resolve floor gap issues for good. 

By reading this page, you’ll learn what causes gaps between floors, walls, and ceilings, how they endanger your home, and how Basement Authority of West Virginia’s comprehensive approach fixes this frustrating problem.  

What Are Floor Gaps? 

Floor gaps refer to open spaces between flooring materials or between floors and walls/ceilings inside a home. Gaps occur when the structures surrounding the floor sink or shift at different rates. You may notice small gaps along the edges of the floor or larger gaps dividing sections of flooring. 

These gaps usually start small but expand over time as soil conditions worsen or foundational issues accelerate. Ignoring minor gaps allows air, moisture, pests, and radon gas to penetrate the interior of your home. 

Floor gaps can accompany other problems, including: 

Left unaddressed, expanding gaps can seriously undermine the structural stability of your floors and walls. 

What Causes Floor Gaps? 

A variety of soil-related factors unique to West Virginia contribute to floor gaps over time, including: 

  • Weak or Improperly Compacted Soil: Soil naturally compacts and settles over time, but weak spots or inadequate compaction during construction accelerates uneven settling. Floors sink quicker than walls, causing separations. 
  • Soil Erosion and Washout: Abundant rainfall combined with poorly draining clay soil causes erosion around foundations. This leaves foundations unsupported, leading to shifting and gaps. 
  • Seasonal Shrink/Swell: West Virginia’s expansive clay soil profile shrinks during drought then swells when rehydrated. This cyclic expanding and contracting pushes up on foundations unevenly, causing gaps. 
  • Old or Damaged Foundation: Outdated rubble foundations and aging poured concrete foundations become unstable. They settle non-uniformly, distorting floor alignments. 

In addition to soil conditions, factors like leaky plumbing, poor drainage, tree roots, and seismic activity can trigger foundation movement and floor gaps. 

Can Floor Gaps Be Fixed? 

Yes, floor gaps can and should be repaired quickly. While gaps may seem like a cosmetic issue at first, leaving them unattended risks serious structural damage, indoor air quality issues, and steep repair costs down the road. 

Attempting DIY repairs with fillers or sealants treats symptoms, not underlying causes. These products inevitably crack or fall out as foundations continue shifting.

  • Minimize Repair Costs: Delaying repairs or opting for temporary fixes can end up being costly. Early intervention helps prevent worsening the problem. 
  • Avert Related Problems: Gaps can be entry points for moisture and pests, leading to issues like mold growth, wood rot, and pest infestations. 
  • Enhance Indoor Comfort: Gaps can disrupt your home’s climate control, resulting in drafts and increased energy bills
