Hardie siding is more expensive than other types of siding, like vinyl, aluminum, and engineered wood, but it’s a high-quality product that can last for 50 to 80 years with good maintenance. It also stands up better to moisture, mold, and insects than wood siding, and provides better curb appeal and a higher ROI than some other options. Overall, it’s an expensive siding material, but it’s often a worthwhile investment.

Hardie board is more expensive than vinyl siding. Vinyl siding costs $3 to $12 per square foot, on average, with cost skewing toward the lower end of that range. Hardie board siding costs $7 to $18 per square foot, depending on the style, color, and trim. However, it lasts twice as long and often looks nicer, meaning you’ll see a higher bump in your home value and greater curb appeal from Hardie board.

The average cost to install Hardie board siding on 2,000 square feet of exterior walls is $21,300. Depending on the complexity of your house, the number of stories, and the style of Hardie board siding you choose, your total could fall anywhere between $15,000 and $25,000. You can get a more accurate price by measuring your exterior walls and multiplying the square footage by $12.50.
