Floor Gaps
Floor gaps can be alarming for homeowners, indicating potential foundation problems. Understanding the causes of floor gaps and the importance of addressing them promptly is crucial to maintaining the structural integrity of your home. This article will explore the common warning signs, causes, and solutions for floor gaps, along with the benefits of choosing JES Foundation Repair for professional floor gap repairs.
What Are Floor Gaps?

Floor gaps refer to noticeable spaces or separations between floorboards or tiles. These gaps can vary in size, ranging from hairline cracks to wider openings. While some degree of natural expansion and contraction of flooring materials is normal, excessive or widening gaps can be a cause for concern.
If you notice gaps between your flooring and baseboards accompanying any of the following warning signs, it’s a cause for concern.
- Sticking doors and windows: If your doors and windows are suddenly difficult to open or close, it could be a sign of foundation settlement, causing uneven floors and gaps.
- Tilting chimney: A chimney that appears to be cracked, leaning, or tilting away from your walls can be a result of foundation settlement, which may also contribute to floor gaps.
- Uneven floors: Floors that slope or feel uneven when walking across them can be a clear indication of foundation problems leading to floor gaps.
- Drywall cracks: Cracks in your drywall, especially near the floor, can indicate foundation issues that may contribute to floor gaps.
What Causes Floor and Wall Gaps?
There are many causes for floor gaps, but the most common ones involve issues with your home’s foundation. We’ll cover several causes below to shine a light on the most likely problems.
- Foundation Settlement: The soil beneath your home can shift over time, causing the foundation to settle unevenly. This settlement can lead to floor gaps and other structural issues.
- Damaged Floor Joists: Weakened or damaged floor joists in your home’s crawlspace can cause sagging floors and gaps between floorboards.
- Expansive Soils: Certain types of soil, such as clay, expand and contract with changes in moisture levels. This movement can exert pressure on the foundation, leading to floor gaps.
Can You Fix Floor Gaps?

Fixing floor gaps is indeed possible, and there are several methods and techniques available to address this issue. The best solution is to fix the underlying foundation issues, as addressed below. Once the foundation repair is complete, you may need to replace warped floorboards or baseboards or use solutions like expansion gap filler.
How to Fix Floor Gaps
- Foundation Piers: Installing foundation piers can stabilize and lift the foundation, closing floor gaps caused by settlement. JES Foundation Repair uses three main types of foundation piers: Helical Piers, Push Piers, and Slab Piers, to adapt to your home’s structure and needs.
- Crawl Space Supports: Strengthening the crawl space with supports can help prevent further sagging and floor gaps. Our chosen method includes IntelliJack™ Crawlspace Support Stablizers, which can uplift bad joists and level out your home.
Why Address Floor and Wall Gaps Now?
It is essential to address floor and wall gaps promptly to prevent further damage and ensure your home’s long-term stability. We’ll highlight the most obvious reasons to act quickly.
- Prevent Further Damage: Ignoring floor gaps can lead to worsening foundation issues, compromising the structural integrity of your home. Small floor gaps are easy enough to cover up, but over time you may need to replace entire sections of flooring or baseboards.
- Avoid More Expensive Repairs: Adding support to your existing structure is much more simple than completely replacing your home’s foundation or crawlspace support. If you act before the problem progresses, you’ll likely save yourself time and money.
- Avoid Other Issues: Addressing floor gaps can prevent secondary problems such as water intrusion, pest infestations, and mold growth.
- Improve Comfort: Closing floor gaps can eliminate drafts and uneven surfaces, improving the overall comfort of your living space. It can also help you prevent water entry events associated with floor gaps.
