Professional sod installation runs about $0.90 to $2.00 per square foot, including the sod, delivery, and labor. For a typical 1,000 to 1,500 sq ft lawn, that's roughly $2,000 to $3,400. Seeding is cheaper at $0.10 to $0.19 per square foot, but you wait weeks for it to fill in — sod gives you an instant lawn. Soil prep and grading, if needed, are usually quoted separately.
