The Pros and Cons of Hardie Board Siding

Hardie board siding (fiber cement siding) is a popular cladding made by blending cement, sand, and wood fibers. It’s known for looking like real wood but with much tougher performance. Many homeowners choose Hardie for its reputation as an extremely durable material that resists weather and fire. In this post, I’ll explore the pros and cons of Hardie board siding so you can make an informed choice. We’ll cover its strengths (like longevity and low maintenance) as well as downsides (like higher cost and installation complexity).

The Pros of Hardie Board Siding

Hardie board siding’s strengths start with durability. Fiber cement boards can last for decades, often 30–50 years, without rotting or warping. This rugged material resists hail, high winds, and even fire. In fact, Hardie siding is non-combustible, meaning it won’t fuel a fire like wood siding would. That makes it a smart pick if you live in a wildfire or storm-prone area. The boards are also extremely pest-resistant – termites, carpenter ants, and even woodpeckers typically leave fiber cement alone. Along with that rugged longevity, Hardie siding comes in many attractive styles and colors. It can mimic wood shakes, clapboard, or modern smooth panels. Hardie’s factory “ColorPlus” finishes keep their color for 15 years and reduce fading, so your house stays vibrant. Finally, these advantages translate to curb appeal and value: this siding often boosts home resale value.  Angi’s fiber cement guide notes these qualities, citing “longevity, durability, and resistance to pests” as key benefits.

What Are the Negatives of Hardie Board Siding?

Even with its many benefits, Hardie board siding has some drawbacks to consider. First, it is heavier and more expensive than materials like vinyl or aluminum. The boards are thick cement, so they cost more per square foot – often two to three times the price of vinyl. Installation also costs more because contractors must use special tools to cut and nail them, and it takes longer to hang them correctly. Handling the heavy boards and cutting the dense material can be labor-intensive. Additionally, cutting fiber cement generates silica dust, which installers must manage with proper safety gear. Hardie siding is also not maintenance-free forever: the factory paint warranty runs about 15 years. After that, you’ll likely want to repaint or re-stain the surface to keep it looking fresh. In cold climates, any siding can suffer if moisture freezes inside it. If fiber cement boards get saturated and then go through many freeze-thaw cycles (for example, splash-up near the ground), they can eventually delaminate or crack over many years. For these reasons, Hardie siding must be installed and sealed properly by experienced professionals.

Is Hardie Siding Worth the Money?

Hardie siding is an upfront investment, so you might wonder: is it worth it? In my experience, it often is for the right homeowner. The key is looking at the long-term value. Yes, the initial price (material plus skilled installation) is higher than some alternatives. But unlike cheaper siding, Hardie can easily last three or four decades. You won’t be replacing it every 10–15 years. That longevity spreads the cost over a long period, and it usually means fewer repairs and a lower life-cycle expense. Many homeowners find the increased curb appeal and longevity boost their home’s resale value. In fact, fiber cement projects routinely recoup a high percentage of cost at sale (some reports cite around 80–90% ROI). If you plan to stay in your home long-term or want top-tier performance, Hardie siding often pays off. Of course, if your budget is very tight or you expect to move soon, cheaper siding might be more practical. But generally, if you compare the cost to the peace of mind (and resale benefit) of a decades-long material, Hardie siding is often worth the extra dollars.

Installation and Upfront Costs

Installing Hardie board siding comes with some special considerations. Because fiber cement is hard and heavy, labor tends to dominate the cost. We learned from a local siding contractor’s analysis that labor for Hardie siding can run about $4–9 per sq. ft., roughly double what vinyl siding might cost. Each board must be measured, cut with saws (to manage silica dust), and fastened carefully. On a simple single-story home, that might be quite efficient; on a multi-story house with many angles, the effort – and thus the bill – goes up. If you’re budgeting, remember that the material itself might be around $2–$6 per sq. ft., while labor makes up the rest. You’ll also have prep costs: tearing off old siding, fixing any wall damage, and adding moisture barriers or insulation. All that adds time and expense. For a clear breakdown of these labor costs and factors, see 614 Exteriors’ guide Average Labor Cost to Install James Hardie Siding which walks through what affects the price. In short, plan on Hardie siding jobs taking more skill and money upfront, but remember that quality installation is key to getting all the promised benefits.

Hardie Board Siding and Moisture

What happens if Hardie siding gets wet? The good news is Hardie is quite water-resistant. Unlike wood, fiber cement doesn’t swell or warp when it rains. James Hardie’s own tests submerged boards in water for seven days straight – and saw no visible swelling or change in thickness (jameshardie.com). FEMA even certifies fiber cement as flood-resistant. In everyday life, normal rain and snow won’t hurt properly installed Hardie siding. Its composition actually allows it to absorb some moisture and then dry back out without damage. However, there are caveats: Hardie is water-resistant, not completely waterproof. If water gets behind the siding (for example, if flashing or caulk fails) or if cut edges are left unsealed, moisture can eventually cause issues over years. In freezing climates, panels that stay wet at the bottom (splash zones) can gradually delaminate if not trimmed or protected. In practice, this risk is low if siding is installed with proper housewrap, trim, and caulking. In summary, a Hardie plank can handle getting wet from rainstorms – but good installation and maintenance (like sealing seams and not burying siding in soil) keep any moisture from becoming a problem.

Maintenance and Longevity

One of Hardie siding’s selling points is that it is nearly maintenance-free, especially when compared to wood. Homeowners typically need only an occasional gentle wash (a garden hose or soft pressure wash) to clear off dust and pollen. The fiber cement itself won’t rot, warp, or invite termites, so you won’t be chasing bugs or replacing rotten panels. If you chose factory-finished “ColorPlus” boards, the finish should stay vibrant for at least 15 years; beyond that, homeowners often repaint for a fresh look or different color. (Repainting isn’t hard, since Hardie holds paint well, but it’s something to plan for in a few decades.) Overall, you can expect Hardie siding to last 30-50 years with minimal upkeep. Many manufacturers even back it with 30-year non-prorated warranties on the structure and 15-year on the finish. In contrast, cheaper materials might need repair or replacement much sooner. It’s worth noting that Hardie siding is mostly made from natural materials and James Hardie has environmentally-friendly manufacturing processes. However, disposal or cutting scrap does create silica dust that installers must handle. On balance, the routine cost of upkeep is low, making Hardie siding a long-lived, durable choice.

Finding the Right Siding Company

At the end of the day, the installation quality is a make-or-break factor for any siding job. Hardie board siding should be installed by professionals who know how to handle it. Cutting errors, improper flashing, or uneven gaps can undermine the siding’s benefits. That’s why I always recommend hiring a qualified siding company to do the job. In Columbus and surrounding areas, 614 Exteriors is an example of a trusted Siding Company in Central Ohio that specializes in James Hardie installations. Whether you choose them or another certified installer, make sure they have experience with fiber cement. A good siding contractor will inspect your home, calculate materials carefully, and follow the manufacturer’s guidelines – ensuring your Hardie siding carries full warranty and performs as advertised. They can also discuss the pros and cons we’ve covered in context, helping you decide if the investment aligns with your goals. Remember, the “cons” like weight and labor-intensive installation can be completely mitigated by picking the right crew. In sum, consult a reliable local siding expert to get the most out of Hardie Board siding and to enjoy its benefits for years to come.

Conclusion: Weighing the Hardie Board Choice

In conclusion, Hardie Board siding delivers on durability, aesthetics, and peace of mind – but it comes with higher costs and installation demands. For many homeowners, its longevity and low maintenance make the pros outweigh the cons. If you’re looking to upgrade your home’s exterior for the long haul, Hardie siding is usually worth considering. I’ve walked through how Hardie resists weather, fire, and pests, and how it holds color and form for decades. I’ve also explained the trade-offs: it requires a bigger budget and skilled installation. By understanding both sides, you can determine if Hardie aligns with your project. And remember, working with a professional [siding company] (like a Siding Company in Central Ohio such as 614 Exteriors) will ensure that your Hardie siding is installed correctly and stands the test of time.
