Why Hardie Board Siding Is Worth the Investment

Hardie Board, officially known as James Hardie fiber cement siding, has become one of the most popular exterior materials for modern homeowners. Built to handle everything from harsh winters to humid summers, it offers exceptional performance that stands the test of time.

In crown point and surrounding areas, homeowners often deal with temperature fluctuations and strong seasonal storms, making durability a top priority for exterior materials.

Here’s why Hardie Board stands out among other siding options:

• Outstanding Durability: Made from a blend of cement, sand, and cellulose fibers, it resists rotting, cracking, and warping even under extreme conditions.
• Low Maintenance: Unlike wood, Hardie Board doesn’t require frequent painting or staining and resists fading over time.
• Fire Resistance: Classified as non-combustible, this siding offers added peace of mind and protection for your home.
• Customizable Style: Available in a wide range of colors, textures, and designs, it fits everything from modern to classic architecture.
• Long-Term Value: Hardie Board siding often comes with warranties that last decades, offering both beauty and protection for years to come.

7 Steps to Installing Hardie Board Siding Like a Pro

Whether you’re planning to tackle a small section of your home or simply want to understand the professional process, the steps below outline how Hardie Board siding is properly installed. Each stage is crucial for ensuring your siding performs and lasts as intended.

1. Prepare the Surface

Before any siding can be installed, the home’s exterior must be inspected and prepared. Professionals start by ensuring that the sheathing and framing are solid and free of moisture damage.

Preparation includes:

• Removing old siding and nails
• Repairing damaged sheathing or trim
• Cleaning debris or buildup
• Installing a weather-resistant barrier (WRB) such as house wrap

This protective layer acts as a moisture shield, preventing water from penetrating behind the siding.

2. Gather Tools and Safety Gear

Working with fiber cement requires specific tools and safety precautions because it’s heavier and denser than materials like vinyl or wood.

Essential tools and supplies include:

• Circular saw with a fiber cement blade or shears
• Measuring tape and chalk line
• Level and framing square
• Galvanized nails or corrosion-resistant screws
• Power drill or nail gun
• Safety goggles, gloves, and a dust mask

Professionals often use cutting tables or dust-reduction systems to minimize exposure to cement particles.

3. Install Flashing and Starter Strips

The foundation of any siding installation is the starter strip. Installed at the bottom of the wall, it ensures that the first row of siding is perfectly level and properly angled for water runoff.

This step involves:

• Attaching galvanized flashing around windows, doors, and rooflines
• Installing metal or fiber cement starter strips along the base of walls
• Double-checking alignment using a level before fastening

Proper flashing prevents water intrusion, one of the main causes of rot and long-term damage.

4. Begin Hanging the First Rows

Once the starter strip and flashing are in place, the first panels or planks are secured. Hardie Board comes in both vertical and horizontal profiles, depending on your home’s design.

For horizontal lap siding:

• Place the first board on the starter strip and fasten it securely
• Use a nail gun or screws to attach the siding to wall studs
• Space nails roughly every 16 inches, leaving a small gap between board ends for expansion

For vertical panels:

• Secure sheets vertically with nails or screws at all four corners
• Overlap panel seams slightly to prevent visible gaps

Precise alignment here sets the tone for the entire installation.

5. Overlap, Seal, and Continue Installation

Each row of siding overlaps the one below it to shed water effectively. Professionals often use spacers or story poles to maintain consistent exposure between rows.

Important details:

• Overlap horizontal planks by about 1¼ inches
• Stagger joints so seams don’t line up between rows
• Apply caulk at corners and around windows for a watertight finish

High-quality, paintable caulk designed for fiber cement ensures the seams stay sealed for years.

6. Trim, Paint, and Finish Edges

Trim pieces give your siding a finished, polished look while protecting edges from moisture. Common trim materials include HardieTrim, PVC, or metal.

Finishing touches include:

• Installing trim around windows, doors, and corners
• Filling nail holes with exterior-grade putty
• Applying touch-up paint or matching finish

Many homeowners choose prefinished Hardie Board products, which come with baked-on color coatings that last much longer than standard paint.

7. Inspect and Clean Up

Once installation is complete, a thorough inspection ensures all fasteners are secure, seams are tight, and no areas were missed.

Inspection checklist:

• Confirm siding is level and evenly spaced
• Verify all joints are properly sealed
• Remove dust and debris from the worksite
• Rinse siding to remove any construction residue

A clean, well-installed exterior is ready to withstand the elements while enhancing curb appeal for years to come.

Common Mistakes to Avoid During Hardie Board Installation

While Hardie Board is one of the most forgiving materials, improper installation can shorten its lifespan or lead to water issues.

Avoid these common pitfalls:

• Skipping the weather barrier: Never install siding directly on sheathing without a moisture barrier.
• Improper nailing: Overdriven nails can crack the board, while underdriven ones cause loosened panels.
• Incorrect spacing: Gaps that are too tight prevent expansion and can cause warping.
• Using the wrong tools: Standard saw blades create dust and uneven cuts—always use tools designed for fiber cement.
• Neglecting caulking and paint: Failing to seal seams properly leaves siding vulnerable to moisture infiltration.

Professionals in crown point and surrounding areas often follow strict manufacturer guidelines to ensure the installation meets both local codes and warranty standards.

Trim Boards	Fiber cement or PVC	Finishing and water resistance
Weather Barrier	Breathable house wrap	Prevents trapped moisture

Investing in the right products ensures both performance and appearance for decades.

Caring for Your Hardie Board Siding After Installation

Hardie Board siding is designed for low maintenance, but simple care will keep it looking pristine.

Recommended care routine:

• Rinse siding once or twice a year with a garden hose to remove dirt and dust.
• Inspect seams and caulking annually for cracks or gaps.
• Repaint every 10–15 years or as recommended by the manufacturer.
• Trim trees and bushes to prevent rubbing or impact damage.
• Check for any loose boards or nails after major storms.

With proper care, Hardie Board siding can last 50 years or more, maintaining its structural integrity and style long after installation.
