LP SmartSide vs Hardie Board: Which Siding Performs Better Long-Term?
April 17, 2026
Did you know that a fiber cement siding project tends to have an average return on investment of nearly 70%? The most popular fiber cement brand, James Hardie siding, in particular, is a great home investment because it’s extremely durable. But just how long does it last, on average?
We’re glad you asked!
Read through this short guide to learn more about the average lifespan of this product and about the features that make it so durable. Once you’re through, you’ll have a better idea of whether it’s the right choice for your home.
The average lifespan of other siding materials like wood, aluminum, and vinyl ranges from 10 to 20 years. So, how does James Hardie siding compare? Well, for starters, it speaks volumes that James Hardie Siding comes with a standard 30-year non-prorated manufacturer warranty.
No other siding material can say the same.
Why is it that their siding is able to offer such an extensive warranty? Let’s take a closer look at some of the properties that make this siding material last for decades.
The first thing that sets James Hardie siding apart is that it’s made using a unique blend of cellulose and sand cement. This makes it resistant to cracking, breaking and fading, which are issues that plague other siding materials.
This durable material is also resistant to moisture, so you don’t have to worry about mold and rot developing over time, as you would with other siding materials.
While wood siding is highly combustible and vinyl siding will melt in a fire, their siding is fire resistant. Because of its unique makeup, this siding material won’t ignite when exposed to direct flames or contribute additional fuel to a fire.
When you have wood siding, in particular, you have to worry about termites and carpenter ants taking a toll on your siding. If you’re not careful, they can cause serious damage, leading to a full siding replacement.
On the other hand, James Hardie siding is resistant to insects and pests, meaning your siding will stay intact for much longer.
Another thing that sets it apart is that it’s made to withstand extreme weather conditions like rain, snow, high winds, and more. They even offer some products specifically designed for certain geographical areas, so you can choose from options that are best for your climate. Proper installation of Hardie Wrap along with fiber cement siding creates a finished siding solution that will protect your home for decades!
While other siding materials fade over time or require frequent painting, you won’t have to worry about that with James Hardie. Their siding color is baked on and made with UV-resistant and fade-resistant properties, so it always looks good as new.
Now that you know more about what makes James Hardie siding last, you’re ready to decide if it’s the right siding material for your exterior remodeling project.
