Hardie Board siding lasts 30–50 years with proper care, outperforming most options and matching or surpassing the lifespan of quality wood. Fiber cement resists rot, insects, fire, and weather, with many 1990s homes still looking great, supporting its durability. James Hardie offers a 30-year limited warranty and a 15-year warranty on ColorPlus finishes.

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 siding is more costly and complex to install than vinyl, requiring specialized tools and skilled contractors, as well as careful dust management due to silica exposure. The process extends timelines, raises costs, and is weather-dependent. Although durable, damages often require professional repairs, and the material’s rigidity can cause cracking under severe impacts or settlement.
