How Much do Helical Piers Cost per Foot Installed?

Based on the provided documentation, there is no flat price per foot for helical pier installation. The total cost is determined by several site-specific variables rather than a standard linear measurement.

Because every project requires unique structural calculations and soil analysis, costs are provided through a custom-quote approach. The following factors are the primary drivers of the final price:

  • Soil Conditions: This is the leading cost driver. Soil composition and groundwater levels dictate the required installation depth and the number of helix plates needed to reach stable ground.
  • Load Requirements: The weight and forces (compression, tension, and lateral) of the structure determine the pier’s diameter and wall thickness (such as Schedule 40 or Schedule 80).
  • Equipment and Accessibility: Limited access, such as interior crawl spaces or the presence of underground utilities, can increase labor hours and equipment complexity.
  • Engineering and Permitting: Engineering design services typically range from $500 to $2,500 per pier. Additionally, a full geotechnical report can cost between $1,500 and $5,000, while local permit fees usually range from $200 to $1,000.

To ensure an accurate and code-compliant estimate, it is recommended to have a structural engineer or technical team review your specific geotechnical report and load requirements.
