The total square footage of your lawn dictates how much material and time we need to complete the job. In St. Louis, MO, the unpredictable weather means you need a solid installation, whether you have a small patio space or a sprawling backyard. For a 100-square-foot area, expect to pay $195 to $765 for materials. If you have a larger 500-square-foot yard, the labor alone runs $1,910 to $4,280. Custom curves or fitting turf around existing hardscaping increases the overall $5,785 because it requires precise cutting and extra labor. If you are also planning a broader backyard renovation, you should factor in landscape design costs alongside your turf budget.

Artificial Grass Cost by Type

We recommend choosing a turf material that withstands the humid summers and icy winters in St. Louis, MO. Your choice of plastic dictates the durability and feel of the lawn. Polypropylene is a mid-range option that costs $5 to $10 per square foot locally and works well for athletic purposes. For a more budget-friendly option, polyethylene runs $5 per square foot and is ideal for low-traffic yards.

The shape of the individual grass blades affects how the turf handles foot traffic and heat. In St. Louis, MO, where heat waves strike in the summer, heat-resistant options like W-shaped blades keep your lawn cooler. Highly durable V-shaped blades stand up to heavy use, while S-shaped blades offer a very realistic look. Investing in the right blade shape ensures your lawn stays pristine, saving you from premature yard cleanup costs down the road.

Base Material

A proper subbase prevents wrinkles, bumps, and flooding during the heavy rainstorms we see in St. Louis, MO. We install this foundational layer to ensure proper drainage and a perfectly smooth surface. Crushed miscellaneous base (CMB) costs $0.50 to $5 per square foot, while decomposed granite runs $5.20 to $5.25 per square foot. A solid base protects your investment and keeps the overall project price closer to the $3,243 by preventing expensive water damage repairs.

Crushed miscellaneous base (CMB)$0.50–$5$0.50–$2
Class II road base$0.35–$5.80$0.35–$1.80
Decomposed granite$5.20–$5.25$1.20–$2.25

Infill

Infill weighs down the turf, keeps the blades standing tall, and protects the backing from the sun's UV rays. Given the extreme weather shifts in St. Louis, MO, the right infill provides necessary cushioning and prevents the grass from matting down. Silica sand is a standard choice at $0.30 per pound, while crumb rubber offers extra bounce for $5.75 per pound. Adding the correct infill completes the installation and pairs well with other yard upgrades, such as sprinkler system removal.

Silica sand$0.30$0.30
Crumb rubber$5.75$1.75
Zeolite$5.15$1.15
Acrylic coated sand$5$1

Labor

The physical work of hauling materials, grading the soil, and securing the turf makes up a significant portion of your total bill. In St. Louis, MO, labor rates fluctuate based on how difficult it is to access your yard and the extent of the necessary ground preparation. Complex jobs with uneven terrain require more time and effort to ensure the lawn survives seasonal flooding and ice storms. You will pay more for labor if your yard needs extensive leveling before we roll out the turf, pushing your total toward the $8,711.

Preparation and Cleanup Costs

Before laying down the new grass, we must excavate the existing soil to create a flat, stable surface. Preparing the ground in St. Louis, MO, involves dealing with hard, clay-heavy soil that requires specialized equipment to remove. Once the installation is complete, we haul away the old dirt, rocks, and organic debris so your property looks immaculate. Proper excavation and thorough cleanup prevent future drainage issues during heavy storms, and you can easily coordinate this step with other projects, like tree stump grinding costs, to fully clear your yard.

Synthetic Grass Installation Pro Costs

Hiring a synthetic grass installation pro in St. Louis, MO, ensures your new lawn drains properly and withstands unpredictable seasonal weather. Local labor rates for this project range from $3.80 to $8.60 per square foot, depending on your yard's terrain and accessibility. For a standard 500-square-foot lawn, you will pay $1,910 to $4,280 per project in labor alone. We recommend bringing in an expert to handle the heavy excavation and precise cutting required for a flawless finish.
