Retaining Wall Cost Factors
Retaining wall costs in Chicago, Illinois, vary by the wall size, materials, material delivery, terrain, site prep, drainage, and more. This detailed overview covers the most important elements to include in your budget.
Size
The length and height of your wall have the biggest impact on price, with taller retaining walls costing more per linear foot. For example, a 2-foot-tall retaining wall costs $30 to $140 per linear foot, while retaining walls up to 6 feet high cost about $250 per linear foot.
The following table summarizes common retaining wall sizes and their average costs. Note that the lower end of the cost range is for walls 2 feet high, while the higher end of the cost range is for walls 6 feet or taller.
| Length (Linear Feet) | Average Cost Range | Average Cost |
|---|---|---|
| 10 | $280–$2,600 | $1,400 |
| 15 | $425–$3,800 | $2,100 |
| 20 | $570–$5,100 | $2,800 |
| 25 | $700–$6,400 | $3,600 |
| 30 | $850–$7,700 | $4,300 |
| 50 | $1,400–$12,800 | $7,100 |
| 100 | $2,800–$25,600 | $14,200 |
| 150 | $4,300–$38,300 | $21,300 |
Materials
The type of material you choose will greatly affect what you pay. Here’s a look at the average prices for common retaining wall materials per square foot.
| Wall Material | Cost Range per Sq. Ft. (All-In) | Average Cost per Sq. Ft. (All-In) |
|---|---|---|
| Vinyl | $5–$10 | $7.50 |
| Railroad ties (wood) | $20–$25 | $22.50 |
| Timber | $10–$20 | $15 |
| Brick | $15–$20 | $17.50 |
| Rammed earth | $15–$20 | $17.50 |
| Gabion | $10–$30 | $20 |
| Stone | $15–$70 | $42.50 |
| Concrete | $20–$35 | $27.50 |
| I-beam | $30–$65 | $47.50 |
| Steel | $10–$100 | $55 |
Material Delivery
Your contractor may charge an extra fee for material delivery. If that’s the case, expect to spend $20 to $70 per truckload of stone, brick, or concrete blocks.
Terrain
The terrain and soil composition in the surrounding area impact the cost of building a retaining wall. Additional labor is needed for sloped grounds, which can increase labor costs by 50% or more. In this situation, the contractor must excavate to construct step-downs or terrace the slope to accommodate a safe retaining wall.
Site Prep
Your contractor will prep the site before building the retaining wall. This may include land clearing, land grading, and tree removal. If your wall is more than 4 feet tall, you’ll need a structural engineer to design it. Here’s what you might pay for site prep.
| Service | Average Cost Range |
|---|---|
| Structural engineering | $250–$525 |
| Land clearing | $75–$175 per hour |
| Land grading | $630–$2,100 |
| Tree removal cost | $140–$1,400 |
Drainage
All retaining walls need drainage, as their purpose is to stop erosion on a slope. There are various methods, including pipes, gravel, weep holes, and criblock designs. If you already have a retaining wall that isn’t properly draining, you may need to spring for retaining wall repair costs ranging from $450 to $950.
Expect to spend $40 to $50 per linear foot on excavation to fix drainage issues. If you’re replacing the wall, it will cost $15 to $20 per linear foot to demolish the old wall and install a new one.
Soil Type
The soil in your yard will determine the type of retaining wall you can build. Certain walls work better with certain soil types. For example, malleable clay soil may not be sturdy enough to support heavy wall materials.
In addition, rocky soil with many boulders will require your contractor to spend extra time clearing the land. It will also be more difficult to excavate, so you can expect higher labor costs across the board.
Reinforcements
Your retaining wall may need reinforcement, which could increase your material and labor costs. A hardscaping pro will add rebar either horizontally or vertically. Rebar costs around $0.60 to $1.10 per square foot. If your wall is particularly long or tall, it may also require footings with different fill materials (costs vary by material).
A structural engineer adds reinforcements when:
The wall is taller than 4 feet
The wall is longer or taller than average
You’re installing a sea wall
You live in a climate with extreme weather
Waterproofing
Waterproofing costs $1.50 to $7 per square foot and can increase the lifespan of your retaining wall. This stops water from seeping into wall joints, which can damage the structural integrity over time. Some materials (like vinyl) are more waterproof than others, so make sure to check with your contractor.
Retaining Wall Pro Costs
The cost of hiring a retaining wall pro in Chicago, Illinois, depends on the project complexity, materials, and installation method.
Labor
Labor is a significant part of retaining wall costs. A local hardscape contractor will charge an average of $35 to $55 per hour or $10 to $35 per square foot. Their rates will also depend on the wall’s materials and the overall complexity of the project. Interlocking retaining wall blocks or pin mechanisms are the fastest and easiest to install compared to hand-stacked limestone or I-beam retaining walls.
Permits
Though it depends on local laws, most homeowners will need a permit to build a wall taller than 4 feet. The cost of building permits varies depending on the valuation of the project, with permits for larger and more complicated projects costing more.
Additional Pros to Consider Hiring
You may need to hire additional pros when building a retaining wall in Chicago, including:
Structural engineer: $340–$780
Land clearing pro: $1,400–$6,200
Land leveling pro: $1,000–$3,300
Tree removal pro: $200–$2,000
Hardscaping pro: $5,000–$18,000
