Subfloor Installation Costs Overview
Different subfloor materials like plywood, oriented strand board (OSB), or concrete influence costs significantly.
Larger rooms or complex layouts increase labor and material requirements, affecting total expenses.
Uneven or damaged substructures may require additional preparation, increasing installation costs.
| Factor | Average Cost Range |
|---|---|
| Material type | $2 to $7 per square foot |
| Room size | Varies based on total area |
| Subfloor repair | $1 to $3 per square foot |
| Preparation work | $0.50 to $2 per square foot |
| Type of subfloor | Plywood: $3-$7, OSB: $2-$5 |
| Labor costs | $1.50 to $4 per square foot |
| Existing floor removal | $1 to $3 per square foot |
| Additional insulation or vapor barriers | $0.50 to $2 per square foot |
In addition to basic installation, factors such as subfloor thickness, moisture barriers, and insulation add to the complexity and cost. An accurate estimate accounts for these variables, ensuring a comprehensive understanding of potential expenses before beginning work.
Plywood and OSB are common choices, each with different cost implications and performance characteristics.
Leveling and repairing existing subfloors can add to the overall cost but ensure durability and stability.
Adding these components enhances performance but increases material and labor costs.
