Understanding Shifting Foundations: Causes, Costs, and Solutions

Foundations form the backbone of any structure, providing the necessary support for a stable and safe home. However, homeowners in Long Island, Brooklyn, Queens, and the Bronx often encounter challenges related to shifting foundations. This issue, if not addressed promptly, can lead to extensive damage and costly repairs. This blog explores the causes, signs, and solutions for shifting foundations, ensuring your home remains secure for years to come.

What Causes Foundations to Shift?

1. Shifting Soil

Soil movement is a leading cause of foundation issues. Factors like expansive clay, improper compaction during construction, or natural soil erosion can cause the ground beneath your home to move, resulting in a shifting foundation.

2. Weather Conditions

New York’s climate—characterized by heavy rains, snow, and freeze-thaw cycles—can affect the soil’s stability. Water saturation causes soil to expand, while drying leads to shrinkage, both of which contribute to foundation movement.

3. Poor Drainage

Inadequate drainage systems around your home can result in water pooling near the foundation, weakening the soil and increasing the risk of shifting.

4. Tree Roots

Trees and large shrubs planted too close to a home can draw moisture from the soil, leading to uneven settling and foundation shifts.

Signs of a Shifting Foundation

Identifying the early signs of a shifting foundation can help prevent severe damage:

1. House Shifting Cracks

• Cracks in walls, ceilings, or floors.
• Gaps around windows and doors.
• Stair-step cracks in brick or concrete walls.

2. Uneven Floors

Floors that slope or sag are a clear indicator of foundation movement.

3. Sticking Doors and Windows

If doors and windows become difficult to open or close, it could be due to foundation settling.

4. Bowed Walls

Interior or exterior walls that bulge or lean signal a significant structural issue.

When to Worry About a Shifting Foundation

While minor cracks may not be a cause for immediate concern, you should take action if:

• Cracks exceed a quarter-inch in width.
• There is visible separation between walls and ceilings.
• Water intrusion is evident through basement floor cracks.
• Your property’s structural integrity is visibly compromised.

How to Address Foundation Shifting

1. Professional Inspection

A thorough inspection by a foundation repair specialist is the first step to assess the extent of the damage and identify its root cause.

2. Shifting Foundation Repair Techniques

• Piering and Underpinning: Installing steel piers to stabilize the foundation.
• Slab Jacking: Lifting sunken areas with grout or foam.
• Wall Bracing: Reinforcing bowed or leaning walls with anchors or braces.

3. Drainage Improvements

Redirecting water away from your foundation through gutters, downspouts, and landscaping modifications can prevent future shifting.

4. Soil Stabilization

Soil treatments, such as injection of stabilizing compounds, can mitigate soil movement and prevent foundation issues.

Shifting Foundation Costs

The cost of addressing a shifting foundation varies based on the extent of the damage and the repair method used. Homeowners in Long Island, Brooklyn, Queens, and the Bronx can expect:

• Minor repairs to start around $1,000.
• Major foundation stabilizations range between $5,000 and $15,000.

Is a Shifting Foundation Covered by Insurance?

Homeowners’ insurance policies typically cover foundation issues caused by sudden, unforeseen events like flooding or earthquakes. However, damage resulting from neglect or poor maintenance may not be covered. Consult your policy or speak with your insurer to understand your coverage.
