What Causes Foundation Cracks in Pennsylvania Homes?

Foundation cracks are one of the most common problems homeowners in Pennsylvania face, especially in areas like North Huntingdon and nearby towns such as Irwin. While some cracks may be harmless, others can signal serious structural issues that threaten your home’s safety and value. Understanding what causes foundation cracks can help you know when it’s time to call in professionals like A Better Choice Inc. for a thorough inspection and repair.

Weather and Soil Conditions in Pennsylvania

One of the biggest reasons homes in Pennsylvania develop foundation cracks is the region’s unique climate and soil makeup.

• Freeze-thaw cycles: Winters in Western Pennsylvania bring freezing temperatures, followed by warmer thaws. As the ground freezes, it expands and pushes against your foundation. When it thaws, the soil contracts, creating pressure changes that can cause cracking.

• Clay-heavy soil: Many parts of the Pittsburgh and Westmoreland County area have clay-rich soil that absorbs water and swells, then shrinks as it dries. This constant shifting places stress on foundations, often leading to cracks.

  
  

Poor Drainage Around the Home

Another common culprit is water. If your yard does not have proper grading, or if gutters and downspouts are not directing water away from the foundation, excess moisture can seep into the soil. Over time, this increases hydrostatic pressure against the walls, which may cause horizontal or stair-step cracks.

Natural Settlement of the Home

All homes settle over time as the soil beneath them shifts. While minor settlement is normal, excessive or uneven settlement often leads to visible cracks in walls and floors. In older Pennsylvania homes, this is especially common because the original building materials may not have accounted for today’s heavier loads and soil movement.

Tree Roots and Landscaping

Trees planted too close to the house can cause foundation issues in two ways. Their roots may grow directly into foundation walls, or they may absorb large amounts of water from the soil, causing it to dry and shrink. Both can result in cracks forming around the base of the home.

Plumbing Leaks and Excess Moisture

Leaky pipes, especially those located in basements or crawlspaces, can lead to excessive moisture in the soil. Over time, this can weaken the foundation and cause cracking. If you notice both water issues and cracks together, it’s critical to have them inspected quickly to prevent further damage.

Construction and Design Issues

Sometimes, foundation cracks are a result of how the home was built. Inadequate soil preparation, poor-quality materials, or design flaws can all lead to long-term foundation instability. Homes in areas like North Huntingdon and Irwin that were built decades ago may not have the same structural standards as newer properties, making them more vulnerable to cracks.

When to Call a Professional

While hairline cracks may seem harmless, it’s important not to ignore them. Large cracks, widening gaps, or water seepage are signs that your foundation may need immediate attention. That’s when experts like A Better Choice Inc. can help with inspections, waterproofing, and repairs tailored to Pennsylvania homes.
