As a siding professional here in Indianapolis, I get this question a lot: “Is HardiePlank worth the extra cost, and how long will it actually last on my home?”
I understand your hesitation. You’re probably comparing it to vinyl siding that costs less upfront, or maybe you’re wondering if the marketing claims about longevity are too good to be true. After installing thousands of square feet of HardiePlank throughout central Indiana over the years, I can give you the straight answer you’re looking for.
Let me walk you through exactly what you can expect from this investment.
What Makes HardiePlank Different (And Why It Matters to You)
First, let’s talk about what you’re actually getting. HardiePlank isn’t just another siding option—it’s engineered fiber cement that James Hardie has been perfecting for over 125 years. The material combines Portland cement, sand, cellulose fibers, and water into something that looks like wood but performs like armor.
Here’s what this means for your home in practical terms: while your neighbor with vinyl siding might be dealing with cracked panels after our last hailstorm, or your friend with wood siding is repainting every few years, your HardiePlank will likely look the same as the day we installed it.
The Real Lifespan Numbers
What James Hardie Guarantees You: They back HardiePlank with a 30-year warranty that doesn’t diminish over time. That means in year 29, you still have the same coverage as year one. Their ColorPlus factory finish gets a 15-year warranty.
What I’ve Observed in the Field: In my experience, properly installed HardiePlank routinely hits the 50-year mark and beyond. I’ve inspected homes with 40+ year old James Hardie siding that still looks solid. Some industry studies suggest it could go 60-100 years under ideal conditions, though I always tell my clients to plan conservatively around that 50-year timeline.
To put this in perspective: if you’re 40 years old and install HardiePlank today, you may never need to replace your siding again.
Why HardiePlank Lasts So Much Longer Than Alternatives
Quality is no concern when considering how long does James Hardie siding last. James Hardie cement board siding is expected to last for decades thanks to its unique make-up. James Hardie fiber cement siding is made from a combination of the following ingredients:
- Portland cement
- Wood cellulose fibers
- Sand
- Water
The result is an extremely durable material that’s made to last. Beyond the material itself, let’s take a closer look at a few of the other reasons for the long lifespan of James Hardie siding.
Key differences you’ll experience:
Against Wood Siding: Wood looks beautiful initially, but here in Indiana, it’s fighting a losing battle against moisture, insects, and temperature swings. I’ve seen gorgeous cedar siding start showing rot issues within 10-15 years without meticulous maintenance. HardiePlank gives you that wood appearance without the headaches—no rot, no termites, no woodpecker damage.
Against Vinyl Siding: Vinyl seems economical upfront, but our Indiana weather is tough on it. Summer heat makes it expand and contract, winter cold makes it brittle. I’ve replaced plenty of vinyl siding that cracked during storms or faded badly after 15-20 years. HardiePlank doesn’t have these temperature sensitivity issues.
The Fire Factor: This might not be top of mind, but it’s worth mentioning—HardiePlank won’t burn. I’ve seen homes where the siding helped slow fire spread, potentially saving the structure. Some of my clients even get insurance discounts for this fire resistance.
What Could Shorten HardiePlank’s Life (And How to Avoid It)
I need to be honest with you about the one major risk: poor installation. This is where about 90% of premature HardiePlank failures happen.
Installation Mistakes That Kill Longevity:
- Using wrong nails or nailing incorrectly
- Inadequate caulking around windows and doors
- Poor flashing and moisture barriers
- Cutting corners on prep work
This is why I always recommend working with James Hardie Elite Preferred contractors like us at Aztec Homes. We’ve completed the training, we use the specified materials, and we understand the installation details that make or break long-term performance.
Your Role in Maximizing Lifespan: The good news is HardiePlank is low-maintenance, but not no-maintenance. Here’s what I tell all my clients:
Clean it twice a year with a soft brush and garden hose—no pressure washing needed. Walk around your home annually and look for any caulk gaps or minor damage. If you went with field-applied paint instead of ColorPlus, plan to repaint every 12-15 years.
Keep your gutters working properly and trim landscaping away from the siding. That’s about it.
Is HardiePlank Right for Your Situation?
Let me help you think through this decision:
HardiePlank Makes Sense If:
- You’re planning to stay in your home long-term (10+ years)
- You want to minimize future maintenance headaches
- You’ve dealt with siding problems before and want them solved permanently
- You’re looking to increase your home’s resale value
- You want the wood look without wood’s problems
You Might Want to Consider Alternatives If:
- You’re flipping the house and need the lowest possible cost
- You’re planning to move within 5-7 years
- Budget constraints make the upfront investment difficult
The Bottom Line: What I Tell My Own Family

With 30-year warranty coverage and real-world performance often exceeding 50 years, this fiber cement siding provides exceptional value through decades of reliable protection.

I’ve been in this business long enough to see homeowners replace vinyl siding twice while their neighbors with HardiePlank haven’t touched theirs. That tells you everything you need to know about real-world value.
