How Much Does Fiber Cement (Hardie Board) Siding Cost for a Whole House?
Fiber cement siding, commonly referred to as Hardie Board, is known for its durability, fire resistance, and wood-like appearance. While it has a higher upfront cost than vinyl siding, many homeowners choose fiber cement for its longevity and performance. Below is a breakdown of what it costs to install fiber cement siding on a typical home using clear assumptions and simple math.
What this article covers
This article focuses on:
Fiber cement siding (Hardie Board)
A 1,000 square foot home footprint
Standard wall height and layout
Mid-range fiber cement products
Professional installation
It does not include premium trim packages, architectural panels, or specialty finishes that can significantly increase cost.
How siding square footage is calculated
Siding is priced by exterior wall square footage, not interior floor space.
For consistency with other siding articles, this example assumes:
A 1,000 sq ft single-story home
Average wall height
Minimal architectural complexity
This typically results in approximately:
1,800 square feet of siding coverage
All calculations below use this figure.
Fiber cement siding material cost
Fiber cement siding is heavier and more rigid than vinyl, which affects material pricing.
A realistic mid-range fiber cement material cost is:
$6 per square foot
For 1,800 sq ft of siding:
1,800 × $6 = $10,800 in material cost
Installation cost
Fiber cement installation is more labor-intensive than vinyl siding due to:
Heavier boards
Cutting requirements
Fastening and sealing details
A realistic average installation cost is:
$7 per square foot
For 1,800 sq ft of siding:
1,800 × $7 = $12,600 in installation labor
Total upfront cost for a whole house
Combining material and installation:
Material: $10,800
Installation: $12,600
Total upfront cost: $23,400
This represents a typical cost to install fiber cement siding on a modest-sized home using mid-range materials and professional installation.
Long-term cost considerations
Fiber cement siding is highly durable but not maintenance-free.
Typically lasts 30–50 years
Requires periodic repainting
Resistant to fire, insects, and rot
While upfront cost is higher than vinyl, longer lifespan can affect long-term ownership cost.
What affects fiber cement siding cost
Total cost can vary based on:
Board style and thickness
Number of cuts and seams
Trim and flashing details
Home height and layout
Regional labor rates
Multi-story homes or complex layouts will increase labor cost.
What this does not include
The costs above do not include:
Removal of existing siding
Insulation upgrades
Rot or sheathing repairs
Decorative trim or custom colors
These items can significantly increase total project cost.
The bottom line
Installing fiber cement siding (Hardie Board) on a typical home with approximately 1,800 square feet of exterior wall area usually costs around $23,400 upfront using mid-range materials and professional installation. Fiber cement siding offers increased durability and longevity compared to vinyl, with a higher initial investment.
