Labor Costs: Professional Installation vs. DIY

Labor represents a substantial portion of your retaining wall investment. Retaining wall labor costs $10 to $30 per square foot, and material prices are $5 to $20 per square foot on average. More specifically, depending on the materials used and the project’s complexity, labor costs can range from $15 to $40 per square foot, with most contractors charging between $50 and $75 per hour.

Several factors influence labor costs:

  • Wall complexity: Complex walls with curves, steps, openings, and other designs increase labor time.
  • Site accessibility: If the ground is sloped, there’s substantial additional labor involved, which can increase labor costs by 50% or more.
  • Wall height: Retaining walls over 3 feet tall need reinforcement, which will increase the cost.

Site Preparation: The Hidden Costs

  • Soil conditions: Soil type affects the overall cost of construction. For example, sandy soils are the best for drainage. On the other hand, clay soil can be very problematic and thus expensive.
  • Drainage systems: Installing a drainage system costs $10 to $30 per linear foot to prevent flooding and erosion.
  • Foundation work: Concrete footings cost $18 to $55 per linear foot, depending on the wall type, size, depth, and soil conditions.

Additional Cost Factors to Consider
