Floor Gaps

Floor gaps can be a frustrating problem for homeowners. Not only do they affect the aesthetics of your home, but they can also be a sign of a more serious issue – foundation problems.

Understanding the causes of floor gaps and taking the necessary steps to address them is crucial in maintaining the structural integrity of your home. This article will explore the reasons behind floor gaps and discuss the importance of timely foundation repair.

What Are Floor Gaps?

Floor gaps refer to the spaces or separations between floorboards or tiles. These gaps can vary in size, from small cracks to wider openings. They are often more noticeable in older homes or those with wooden flooring, where the flooring pulls away from the baseboards. While some minimal gaps can be considered normal due to seasonal changes and natural settling, larger and more persistent gaps are a cause for concern.

If you notice any of the following indicators of foundation damage along with your floor gaps, it’s a good idea to call our experts for a free inspection:

  • Drywall Cracks: One of the most common signs of foundation issues is the appearance of cracks in the walls or ceilings. These cracks often start near the floor and extend upwards, indicating that the foundation has shifted or settled.
  • Sticking Doors and Windows: If you notice that your doors and windows are suddenly difficult to open or close, it may be due to the unevenness caused by a compromised foundation. This can lead to misalignment and gaps between the frames and the walls.
  • Uneven Floors: If you feel like your floors are no longer level or notice a slope in certain areas, it could be a result of foundation settlement. This can cause gaps to form between the floorboards or tiles.
  • Tilting Chimney: A tilting or leaning chimney is a red flag for foundation problems. As the foundation shifts or settles, it can cause the chimney to become unaligned with the rest of the house, resulting in gaps and cracks.

What Causes Floor and Wall Gaps?

  • Foundation Settlement: Over time, the soil beneath your home can shift or compress, leading to foundation settlement. This can occur due to various factors such as poor soil conditions, improper construction techniques, or changes in moisture levels. As the foundation settles, it can cause the floors and walls to separate, resulting in gaps. 
  • Damaged Floor Joists: Floor joists provide support to the flooring system of your home. If these joists become damaged or weakened, they can cause the floors to sag or separate, leading to gaps. 
  •  Expansive Soils: Certain types of soil, known as expansive soils, have a high clay content that expands when exposed to moisture and contracts during dry periods. This constant movement can exert pressure on the foundation, leading to cracks and gaps in the floors and walls.

Can You Fix Floor Gaps?

Fortunately, floor gaps caused by foundation issues can be addressed through professional foundation repair methods.

Here are some common solutions:

  • Foundation Piers: Foundation piers are installed deep into compacted soil beneath your home to stabilize and lift the foundation. This helps to close the gaps and prevent further settlement. Depending on your home’s needs, we’ll either use Helical Piers, Push Piers, or Slab Piers to stabilize your foundation.  
  • Crawl Space Supports: In some cases, floor gaps may be caused by inadequate support in the crawl space. Installing additional supports can help to level the floors and eliminate gaps.

Why Address Floor and Wall Gaps Now?

  • Prevent Further Damage: Ignoring floor gaps can lead to more severe foundation problems over time. By addressing the issue promptly, you can prevent further damage and potential safety hazards. Foundation problems can impact other areas of your home, such as plumbing and electrical systems. By addressing floor gaps, you can mitigate the risk of additional issues arising.
  • Avoid More Expensive Repairs: The longer you wait to repair foundation-related floor gaps, the more extensive and costly the repairs may become. Timely intervention can save you from significant financial burdens down the line.
  • Improve Comfort: Uneven floors and gaps can make your home uncomfortable to live in. Uneven walkways can also cause those with mobility issues to trip or fall. By fixing the foundation and eliminating floor gaps, you can restore the comfort and functionality of your living space.
  • Protect Property Value: A compromised foundation can significantly decrease the value of your home. By investing in foundation repair, you can protect your property’s value and ensure a solid foundation for future buyers.
