How much does it cost to install a retaining wall? Check out these estimates.
Planning a retaining wall project in the Twin Cities area? Understanding the costs involved is crucial for making informed decisions about your investment. As experienced retaining wall contractors serving Minneapolis, St. Paul, Burnsville, and surrounding communities since 2004, we're breaking down everything you need to know about retaining wall costs in 2025.
Retaining wall costs in the Minneapolis-St. Paul metro area vary significantly based on materials, height, length, and site conditions. Here's what Twin Cities homeowners can expect to invest:
Concrete Block Retaining Walls: $15-$35 per square foot
Poured Concrete Retaining Walls: $20-$45 per square foot
Natural Stone Retaining Walls: $25-$75 per square foot
Engineered Block Systems: $12-$30 per square foot
Timber Retaining Walls: $10-$25 per square foot
2-4 feet tall: $2,000-$8,000 for typical residential installations
4-6 feet tall: $4,000-$15,000 (requires engineering in many municipalities)
6+ feet tall: $8,000-$25,000+ (always requires professional engineering)
Note: Costs include materials, labor, drainage, and basic excavation for standard conditions.
Soil Type: Minnesota's varied soil conditions significantly impact costs. Clay soils common in the Twin Cities area may require additional drainage, while sandy soils near river areas often need deeper foundations.
Slope Severity: Steep slopes require more complex engineering and potentially stepped wall systems, increasing costs by 20-40%.
Access: Limited access for equipment can increase labor costs. Hand excavation instead of machine work can double installation time.
Existing Structures: Working around existing concrete driveways, utilities, or landscaping adds complexity and cost.
Straight Walls: Most cost-effective design
Curved or Terraced Walls: 15-30% premium over straight walls
Integrated Features: Steps, planters, or lighting add $500-$2,000+ per feature
Decorative Finishes: Stamped patterns or staining add $3-$8 per square foot
Different Twin Cities municipalities have varying requirements that affect costs:
Building Permits: $50-$300 depending on city and wall height
Engineering Requirements: Walls over 4 feet typically require professional engineering ($1,500-$3,500)
Setback Requirements: May affect design options and excavation needs
Spring (March-May): Peak demand, 10-15% higher costs
Summer (June-August): Standard pricing, best weather conditions
Fall (September-November): Slight discounts possible, weather-dependent
Winter Planning: Best time to plan and get quotes for spring installation
Many homeowners underestimate these additional expenses:
Proper Drainage: $5-$15 per linear foot for drainage pipe and stone
Excavation: $3-$8 per cubic yard, depending on soil conditions and access
Soil Disposal: $20-$40 per cubic yard if soil can't remain on-site
Utility Location: $200-$500 for professional utility marking
Tree/Shrub Removal: $100-$1,000+ depending on size and quantity
Existing Hardscape Removal: $2-$8 per square foot
Engineering: Required for walls over 4 feet, $1,500-$3,500
Surveying: May be required for property line walls, $500-$1,500
Structural Analysis: For complex sites or tall walls, $1,000-$2,500
Plan in Winter: Get quotes and permits during off-season
Flexible Scheduling: Contractors may offer discounts for flexible timing
Multiple Projects: Combine with driveway work or patio installation for potential savings
Minimize Curves: Straight walls are more cost-effective
Standard Heights: Keeping walls under 4 feet avoids engineering requirements
Efficient Drainage: Proper initial design prevents costly repairs
Local Materials: Minnesota-sourced stone and aggregates reduce transportation costs
Standard Sizes: Custom block sizes increase costs significantly
Volume Discounts: Larger projects often have better per-unit costs
Many Twin Cities banks offer specialized home improvement loans for hardscaping projects with rates typically 2-4% lower than credit cards.

Some contractors, including established companies like Preferred 1 Concrete, offer financing options or partnerships with lending companies.
