The cost of helical piers for residential foundation repair in the Denver metro area, including Centennial, typically ranges from $150 to $400 per pier. This price generally includes both materials (high-quality steel piers with brackets and fasteners) and labor.
Several site-specific factors can influence the final price per unit:
- Soil Composition: In areas with expansive clay, piers often need to be driven deeper to reach stable ground, which can increase the cost by 15% to 30%.
- Installation Depth: Piers are installed at depths ranging from 5 to 30 feet. Deeper installations require more shaft sections and labor, increasing the cost proportionally.
- Quantity Efficiencies: While the total project cost increases with more piers, the price per pier may decrease for larger projects (typically 6–10 piers) due to mobilization efficiencies.
- Site Accessibility: Locations that require hand-digging or have limited access for machinery may involve higher labor costs.
In a professional quote from ACN Construction, the price typically covers the installation crew, minimal excavation and backfilling, necessary building permits, inspections, and a 20-year warranty on materials.
