Calculator Use
This fiber cement siding cost calculator is designed to provide homeowners and contractors with an accurate estimate for installing fiber cement siding (commonly known as Hardie board). By inputting your specific project details, you can compare different price points for materials and professional installation services.
To get the most accurate result, follow these input guidelines:
- Total Wall Area (sq ft)
- The total exterior surface area of your home that requires siding. Subtract areas for large windows and doors for better precision.
- Material Cost per sq ft
- The price of the fiber cement panels or planks. Typically ranges from $2.00 to $7.00 depending on the brand, style, and finish.
- Labor Cost per sq ft
- The cost for professional installation. Fiber cement is heavy and requires specialized tools, leading to labor costs between $5.00 and $12.00 per square foot.
- Waste Factor (%)
- An allowance for cuts, mistakes, and overlapping. 10% is standard for simple homes, while 15-20% is recommended for complex architecture.
How It Works
When planning a renovation, understanding the math behind the quote is essential. The fiber cement siding cost calculator uses a linear formula to combine material and labor rates against your total square footage, adjusted for a waste margin.
Total Cost = [Area × (1 + Waste %)] × (Material Price + Labor Price)
The key variables include:
- Siding "Squares": In the industry, 100 square feet is called a "square." Professionals often quote by the square.
- Substrate Preparation: The calculator assumes a clean surface. Costs may increase if the old siding needs removal (tearing off wood or vinyl).
- Fasteners and Trim: Remember that trim pieces (corners, soffits) often cost more per linear foot than the siding itself.
Calculation Example
Example: A standard two-story home with 2,000 square feet of wall space using mid-range pre-painted fiber cement planks.
Step-by-step solution:
- Total Area = 2,000 sq ft
- Waste Factor = 10% (Multiplier = 1.10)
- Material Cost = $6.00 /sq ft
- Labor Cost = $9.00 /sq ft
- Adjusted Area: 2,000 × 1.10 = 2,200 sq ft
- Material Total: 2,200 × $6.00 = $13,200
- Labor Total: 2,200 × $9.00 = $19,800
- Final Result: $13,200 + $19,800 = $33,000
Common Questions
Is fiber cement siding more expensive than vinyl?
Yes, fiber cement generally costs 1.5 to 2 times more than standard vinyl siding. However, it offers superior durability, fire resistance, and a more "authentic" wood look that increases home value significantly more than vinyl does.
Can I install fiber cement siding myself?
While possible, it is not recommended for most DIYers. The material is very heavy, brittle before installation, and requires specialized cutting tools to avoid inhaling hazardous silica dust. Improper installation can also void the manufacturer's warranty.
How long does fiber cement siding last?
Most fiber cement products, such as those from James Hardie, come with a 30-year non-prorated limited warranty. With proper maintenance and painting every 10-15 years, the material can easily last 50 years or more.
Does the cost include painting?
This depends on the product. "ColorPlus" or factory-finished boards cost more upfront but save you the cost of painting on-site. If you buy "primed" siding, you must factor in an additional $2-$4 per square foot for professional painting after installation.
