Floor Gaps

When you notice gaps between your walls and floors, it’s often an indication of an underlying issue with your home’s foundation. Not only do these gaps compromise the aesthetics of your home, but they can also develop into major structural concerns.  

With more than 25 years of experience, BQ Basements & Concrete is your go-to source for diagnosing and repairing foundation problems, including floor gaps. 

What Are Floor Gaps? 

Floor gaps are visible spaces that develop between your home’s walls and floors. These gaps generally begin as minor openings but can widen over time, revealing severe foundational problems. 

Ignoring floor gaps is risky. These visible spaces are a clear sign of underlying foundation instability, which puts the integrity of your home at risk. 

Additional symptoms that often accompany floor and wall gaps are: 

At BQ Basements & Concrete, we offer cutting-edge techniques to permanently address your floor gaps and secure your home’s structural stability. 

What Causes Floor and Wall Gaps? 

Various factors contribute to the separation of your home’s floors from its walls: 

Soil Movement 

One primary reason is inconsistent soil support. As the soil beneath your home moves, it becomes less able to sustain the weight of the foundation properly. This can cause the foundation to sink unevenly, creating cracks and gaps between the floor and walls. 

Weakening Floor Joists 

Homes with crawl spaces can suffer from weakening floor joists. Whether due to excessive moisture or over spanning, this degradation results in sagging and eventually in gaps between the walls and floors. 

Soil Fluctuation 

Some soils, such as clay, can expand or contract based on moisture levels, putting stress on your foundation. This can result in gaps forming between the walls and floors. 

Can You Fix Floor Gaps? 

Rest assured, floor gaps can be repaired, but understanding the root cause is crucial. Simply covering the gaps is a mere cosmetic fix and won’t solve the underlying issues. 

How to Fix Floor Gaps 

At BQ Basements & Concrete, our certified inspectors conduct comprehensive evaluations to identify the causes of your floor and wall gaps.  

We then create a custom repair plan using advanced solutions like: 

  • Foundation Piers: We employ three types of piers—push, slab, and helical—to reinforce and possibly lift sinking foundations, effectively closing gaps. 
  • Crawl Space Reinforcement: We use adjustable support posts to permanently strengthen sagging floor joists, helping to reduce gaps. 

With over 25 years in the field, BQ Basements & Concrete can reliably address your floor gaps, offering permanent solutions. 

Why Address Floor and Wall Gaps Now? 

Taking quick action against floor and wall gaps is crucial for multiple reasons: 

  • Prevent Escalating Damage: If not dealt with, gaps can lead to significant structural issues, such as collapsing walls or floors. 
  • Save Money: Temporary fixes won’t help and can exacerbate your foundation issues, leading to costlier repairs. 
  • Avoid Additional Risks: Gaps can be entry points for moisture and pests, leading to other problems like mold and infestation. 
  • Increase Home Comfort: Sealing gaps helps maintain a stable indoor climate, preventing drafts and reducing energy costs. 
  • Maintain Property Value: Unattended foundation issues will adversely affect your home’s market value.

Floor Gaps FAQs

Enlarging gaps, stubborn doors and windows, and additional drywall fractures are signs that the issue is progressing.  

Minor gaps can typically be corrected in one to two days, following a structured plan. For severe foundational issues, expect a 1-2 week repair timeline. 

Filling gaps with foam or caulk will not tackle the root cause of the problem. For a long-term fix, it’s crucial to engage in structural repairs of the foundation.
