Hardie Board Siding Cost Calculator

How Much Does Hardie Board Siding Cost?

$8,000 to $20,000 is the average cost to install Hardie board siding on a typical home, with most homeowners paying around $14,000 for roughly 1,500 square feet of HardiePlank lap siding including labor and materials. For a full tear-off and replacement, expect to pay $9,000 to $23,000 depending on the product line, home size, and how many stories your home has.

James Hardie fiber cement siding is the most popular brand-name siding product in North America, installed on over 8 million homes. It is made from a mix of cement, sand, and cellulose fibers that creates a material tougher than vinyl, more fire-resistant than wood, and built to handle harsh weather in every climate zone. If your existing siding is cracked, faded, or showing signs of rot, Hardie board is a long-term replacement that typically recoups 80% to 90% of its cost at resale.

Hardie Board Siding Cost by Product

HardiePlank lap siding costs $6 to $11 per square foot installed, making it the most affordable option in the James Hardie lineup. Each Hardie product has a different price point depending on the style and thickness. Here is what you can expect to pay in 2026:

Hardie Product	Cost per Sq Ft (Installed)	Avg Home (1,500 sq ft)
HardiePlank Lap Siding	$6 - $11	$9,000 - $16,500
HardieShingle Siding	$8 - $13	$12,000 - $19,500
HardiePanel Vertical Siding	$7 - $12	$10,500 - $18,000
HardieTrim Boards	$5 - $8 per linear ft	$1,500 - $3,500 (trim only)

HardiePlank lap siding accounts for the majority of residential installations. It comes in smooth and woodgrain textures, with boards available in 5.25-inch to 12-inch widths. The ColorPlus factory-painted finish adds about $1 to $2 per square foot over primed boards but saves the cost of on-site painting and comes with a 15-year color warranty.

HardieShingle panels replicate the look of cedar shake shingles without the fire risk or maintenance headaches. They are popular for accents on gable ends, dormers, and upper stories. HardiePanel vertical siding gives a modern board-and-batten look and installs faster than lap siding because each 4x8 or 4x10 panel covers more area per piece.

Factors That Affect Hardie Board Siding Cost

$8,000 to $20,000 is the typical range, and several factors push your project toward the low or high end of that window.

Home Size and Wall Area

Exterior wall area is the biggest cost driver, typically ranging from 800 to 3,000+ square feet of sideable surface. A smaller home under 1,000 square feet may have just 800 square feet of walls, while a 2,500+ square foot home can have 2,500 or more square feet of exterior surface. Windows and doors reduce the total sideable area by roughly 10% to 15%.

Number of Stories

Two-story homes cost 15% to 25% more, and three-story homes cost 25% to 40% more than single-story installations. Hardie board planks weigh about 2.5 pounds per square foot, significantly heavier than vinyl, so multi-story work requires scaffolding, more labor hours, and specialized equipment to lift materials. Contractors charge more per square foot for anything above the first floor.

Old Siding Removal

Removing existing siding adds $1,000 to $3,000 to your total cost. James Hardie recommends removing old siding rather than installing over it, and overlay installations may void the product warranty. Removal lets contractors inspect sheathing for rot or moisture damage and install fresh house wrap, which is critical for fiber cement performance. If you are replacing old siding ($5,000 to $15,000 depending on material), plan for the removal cost as part of your budget.

Trim and Accessories

Adding HardieTrim around windows, doors, and corners costs $1,500 to $3,500 for an average home. HardieTrim boards at $5 to $8 per linear foot match the fiber cement siding in durability and appearance. Most contractors strongly recommend using HardieTrim instead of wood or PVC trim for a consistent look and warranty coverage. A typical home needs 200 to 500 linear feet of trim.

Finish and Color

ColorPlus factory-finished siding costs $1 to $2 more per square foot than primed siding, adding $1,500 to $3,000 to a typical project. The factory finish provides a baked-on coating that is more durable than field-applied paint and carries its own 15-year warranty. Primed siding requires on-site painting at $1 to $3 per square foot, which can erase the savings. Most contractors recommend the ColorPlus option for the better finish quality and lower long-term maintenance.

Hardie Board vs. Other Siding Materials

$6 to $11 per square foot for Hardie board puts it in the mid-to-upper range of siding materials, but its 30 to 50 year lifespan makes it one of the best values per year of service. Here is how it stacks up against the alternatives:

Siding Material	Cost per Sq Ft (Installed)	Lifespan	Maintenance
Vinyl	$4 - $8	20 - 30 years	Low (wash occasionally)
Hardie Board (Fiber Cement)	$6 - $11	30 - 50 years	Low (repaint every 15 - 20 yrs)
Wood (Cedar)	$8 - $16	15 - 40 years	High (stain/paint every 3 - 7 yrs)
Aluminum	$6 - $12	40 - 60 years	Low (can dent)

Vinyl is the cheapest option but cannot match Hardie board in durability, fire resistance, or curb appeal. Vinyl warps in extreme heat and can crack in freezing temperatures. It also melts if a grill or fire pit is too close.

Wood siding costs more than Hardie board and requires significantly more maintenance. Cedar shingles and clapboards look beautiful but need staining or painting every 3 to 7 years to prevent rot, which adds thousands in upkeep costs over the life of the siding.

Aluminum siding lasts a long time but dents easily and tends to look dated. It is increasingly hard to find contractors who specialize in aluminum installation.

For most homeowners weighing cost against longevity and curb appeal, Hardie board hits the sweet spot. It is the top-selling brand-name siding in the country for good reason.

How to Save Money on Hardie Board Siding

$1,000 to $5,000 in savings is realistic if you plan your project carefully. Here are some practical ways to cut costs without cutting corners.

• Get at least 3 quotes. Hardie board installation bids can vary by 20% to 30% between contractors. Make sure each quote breaks out materials, labor, removal, and trim separately so you can compare fairly.
• Schedule in the off-season. Siding contractors are busiest from May through September. Booking your project in late fall or winter can save 10% to 15% on labor in many markets.
• Use HardiePlank on less visible walls. If you want the look of HardieShingle on the front of your home, you can use the less expensive HardiePlank lap siding on the sides and back to save $1 to $3 per square foot on those areas.
• Choose primed over ColorPlus if you plan to paint. If you are having the exterior painted ($1,000 to $3,500 for interior work, with exterior painting running higher), primed boards cost less upfront, though you will lose the factory finish warranty.
• Bundle siding with other exterior projects. Combining siding with a roof replacement or window installation saves on scaffolding setup and mobilization fees since the crew is already on-site.
• Hire a James Hardie Preferred contractor. Preferred contractors often have access to manufacturer promotions and extended warranties that offset their slightly higher labor rates.
