Read more in our guide below, which also compares Hardie siding to alternatives.

What Is Hardie Siding?

The James Hardie Company first introduced its brand of fiber cement siding in the mid-1980s. Hardie siding is made of a composite of cement, sand, and cellulose fibers and can resist fire, pests, and rot. It’s also suitable for most climates and weather conditions.

Fiber cement siding is now available from other manufacturers, but Hardie remains the most popular brand. Below are some reasons why:

• Available in various styles: Homeowners can get Hardie siding in styles such as board and batten, clapboard, and shakes. It’s also available in most colors.
• Damage-resistant: Hardie siding is both fire-resistant and pest-resistant.
• Durability: Hardie siding holds up well in most conditions and won’t easily crack, warp, or rot. It’s so durable that some manufacturers offer warranties lasting up to 50 years.
• Minimal maintenance involved: Hardie siding requires very little maintenance. Homeowners can wash it with a garden hose to keep it clean.
• Sustainable: Hardie siding is made of natural materials, so it’s more eco-friendly than siding choices such as vinyl. Less of it winds up in landfills because of how long it lasts.

Common Problems with Hardie Siding

While Hardie siding is durable and cost-effective, it can become a headache for homeowners. Read more about potential problems and how to handle them below.

Cracking and Chipping

Hardie boards are resistant to most types of damage, but some homeowners find that their siding cracks, warps, or chips due to improper installation. Using the wrong nails or faulty flashing could damage the siding, and a foundation that settles a lot could crack Hardie board.

Get ahead of these issues by hiring a professional to install Hardie siding and survey your house’s foundation. If you spot cracks in your siding, ask a professional to fix them immediately. Regularly inspecting siding can prevent damages to your home.

Cost

Hardie siding is more expensive to install than vinyl because of the materials and labor required. Over the course of a lifetime, though, the cost of Hardie siding is usually much less since it requires infrequent maintenance and lasts longer.

Fading and Discoloration

Homeowners don’t have to repaint Hardie siding regularly, but fiber cement can fade in the sun. Exposure to ultraviolet (UV) rays could bleach the appearance of Hardie board, making your home’s exterior look uneven. Fading may also occur if you use low-quality paint or primer.

Prevent these issues by choosing fade-resistant paints in dark colors. Keep your siding clean to stop fading and repaint whenever necessary.

Moisture Absorption

Siding is meant to protect your home against water damage, but Hardie siding can absorb moisture if installed incorrectly or if it stays wet for long. Prevent moisture damage by ensuring that the roof’s flashing, drainage, and fascia are all in good shape.

Installation Issues with Hardie Siding

Hardie siding is ultimately only as good as its installation. Putting up Hardie siding is complex, even for seasoned pros, because of its weight and complicated installation steps.

Below are some common mistakes that may occur during the installation of Hardie siding:

• Bad drainage: Installers must ensure that drainage systems around the home are adequate. Insufficient flashing or poor drainage could cause water damage to the siding or allow mold growth behind it.
• Improper nailing: Proper installation of HardiePlank siding requires a specific nail type along with exact spacing and depth. Using the wrong nails could lead to improper fastening, which may cause the boards to warp, crack, or chip.
• Mishandling: Hardie siding is very heavy and requires lots of strength to move. Placing boards incorrectly can lead to gaps that allow water to penetrate boards, even if caulk is applied. Exposure to silica dust during installation can also be hazardous, so wear a mask when handling and cutting Hardie board.

The potential consequences of improper installation likely outweigh any savings you might get from installing Hardie siding yourself. Trusting a professional to install Hardie board will most likely help you find the best return on investment.

Longevity Concerns with Hardie Siding

Hardie siding is one of the most cost-effective lap siding materials and can last up to 50 years. However, you’ll need to prepare for a few variables to get the most out of your investment.

• Climate: Hardie siding won’t last as long in areas that are extremely hot or wet. UV rays could cause the color to fade while prolonged exposure to moisture may warp boards. Hail and ice can also damage Hardie board siding.
• Installation: A Hardie siding product will last long only if it’s been installed correctly. Follow Hardie installation instructions exactly to ensure that the material is secure and to protect your home against water damage.
• Maintenance: A little maintenance goes a long way when it comes to extending the life of Hardie siding. Periodically hosing off your siding can help to remove built-up dirt and debris that causes damage. Repair any warping, cracks, or chips immediately.

The life span of Hardie siding is typically up to 50 years. Here’s how that compares to other siding materials:

• Brick or stone: Up to 100 years
• Fiber cement board: 30 to 50 years
• Stucco: 50 to 80 years
• Vinyl siding: 20 to 40 years
• Wood siding: 10 to 30 years

Comparisons with Other Types of Siding

Below, you’ll see how the pros and cons of Hardie siding match up to those associated with other popular siding types.

Our Recommendation
