Understanding Repair Costs

The cost of a foundation crack repair can vary greatly based on factors such as the extent of the damage, accessibility, materials needed, and whether exterior or interior repairs are required.

  • Exterior Crack Repair: This approach involves excavating around the house to the full depth of the foundation walls, which then allows the crack to be sealed from the outside. It can be more costly due to the labor and materials involved, typically costing between $65 to $125 per linear foot.
  • Interior Crack Repair: Alternatively, cracks can often be fixed from inside the basement with an injection of high-pressure epoxy or polyurethane. Generally, less labor-intensive, these repairs can range from $400 to $800 per crack.

Specialized Cost Factors

  • Size of Crack: Minor crack repairs generally cost less than larger, more extensive ones. Small crack repairs can start around $500, while extensive damage may move up to a few thousand dollars.
  • Site Accessibility: Depending on the location and accessibility of the cracks, additional labor or equipment may be needed, impacting the overall cost.
  • Additional Services: Other services, like sump pump installation, dehumidifiers, or drainage systems might be necessary for some basements and will add to the overall cost.
  • Recurring Damages: If a crack reopens due to house settlement or other issues, a further repair may require installing carbon fiber strips to prevent shifting walls, affecting the cost.

Do Cracked Foundations Always Need Repair?

To answer simply: not all foundation cracks are created equal. Some hairline cracks may appear as a result of the normal curing process of concrete, which might not require repair. However, horizontal, vertical or diagonal cracks wider than one-eighth inch can indicate likely structural issues and may let water seep into the basement. It’s always best to seek a professional opinion if you’re in doubt.
