Before you dial in your design or make the plunge on your exterior restoration, take a closer look at Hardie board siding.

What Is Hardie Board Siding?

Crafted by James Hardie, Hardie board siding stands as a premier example of fiber cement mastery. Unlike vinyl siding, this engineered product combines sand, cement, and cellulose fibers to form a composite material that’s sturdy, termite-resistant, and impervious to water. This results in a siding solution that effectively mimics the appearance of wood without its inherent drawbacks.

The Manufacturing Process

The creation process of Hardie board is meticulous, starting with a slurry of the main ingredients. Once mixed and poured, it’s compressed using a hydraulic press to form rough, thick sheets. These are then cured to harden the material and cut into individual panels with specific dimensions. The panels undergo a painting process that seals their surface and ensures longevity against UV rays and weather damage, offering a wide range of colors and finishes to prospective homeowners.

Pros of Hardie Board Siding

Hardie board siding boasts an impressive array of advantages. Here’s a detailed look at why homeowners are increasingly swayed by its benefits:

Unrivaled Durability

Hardie Board’s resilience is one of its most celebrated features. Immune to many common ills, including rot, pests, and warping, it’s a siding that can stand the test of time. It’s also non-combustible, making it a wise choice for homeowners in fire-prone areas.

Color Retention and Moisture Resistance

James Hardie’s ColorPlus Technology protects against fading and chipping, a common complaint with painted siding. The material’s resistance to moisture means it won’t swell, crack, or soften, even in harsh weather conditions.

Low Maintenance

Unlike wood, Hardie board doesn’t require scraping or painting nearly as often, saving you time and money. A semi-annual rinse with a garden hose keeps it looking its best year-round.


Made from sustainable materials, Hardie board is an environmentally-conscious choice for homeowners. Its durability also lessens the impact on the planet by extending the time between necessary replacements.

Design Flexibility

Thanks to the advanced manufacturing process outlined earlier, Hardie board siding can be made to mimic various textures, from smooth to rustic to intricate wood grain, allowing you the flexibility to match your design vision.

The Cons of Hardie Board Siding

No material is perfect, and Hardie board siding is no exception. It’s important to consider the following drawbacks before making a decision:

Higher Initial Cost

Compared to standard vinyl siding, Hardie board has a higher initial cost. This can be a significant factor for homeowners on a budget, although the long-term savings in maintenance may offset the difference.

Specific Installation Requirements

Correct installation is vital to the performance of Hardie board siding. Ensuring proper flashing, seam treatments, and leaving adequate gaps to prevent water buildup are essential. Unfortunately, not all contractors are well-versed in these techniques.

Heavyweight Material

The weight of Hardie board can be a challenge during installation, requiring more effort and sometimes additional structural support, which could add to the overall cost of the project.

Comparisons with Other Siding Materials

It’s vital to consider your options. Below, we break down how Hardie board siding stacks up against vinyl, wood, and metal options:

Vinyl Siding

While vinyl siding offers a budget-friendly option, it pales in comparison to Hardie board’s durability and resistance to impact, moisture, and fire. James Hardie products are worth the investment because they hold up for a long time.

Wood Siding

The aesthetic appeal of natural wood is undeniable, but it comes with the cost and effort of regular maintenance. Hardie board beautifully imitates the look and is virtually maintenance-free.

Metal Siding

Metal siding is durable, but Hardie board is superior in its ability to absorb impact and its broader range of design options, making it a more versatile choice for many homeowners.

Considering the significant investment and the pivotal role your home’s exterior plays, it’s worth doing thorough research and consulting with professionals before making a decision. Ultimately, the best choice is one that aligns with your home’s architectural needs, your personal preferences, and your budget.

Installation and Maintenance Tips

Here are some helpful tips for installation and maintenance to ensure your Hardie board siding looks great and lasts:

Installation Best Practices

Hire a professional with experience in working with fiber cement. They should follow manufacturer guidelines to avoid issues down the line.

Sealing and Flashing

Water is the primary enemy of your home’s structure. Proper sealing and flashing techniques are non-negotiable to protect against leaks.

Regular Inspections and Swift Repairs

Periodic inspections can catch issues before they become significant problems. This is vital in maintaining the integrity of your home’s exterior.
