Fiber cement siding costs $9 to $20 per square foot installed, putting a full re-side on a typical 2,000 sq ft home between $14,000 and $26,000. That range spans three brands with very different pricing and warranty structures. James Hardie dominates the category. LP SmartSide undercuts it on price, and Nichiha operates as a regional alternative most homeowners never hear about.
The broader vinyl vs fiber cement comparison covers material-level tradeoffs. This guide digs into which product to pick, what the warranties actually cover, and the installer certification requirement that can silently void your 30-year coverage.
Fiber Cement Cost by Brand
Brand choice drives more than sticker price. Installation complexity and warranty coverage shift significantly between these products, and regional availability narrows the field further.
| Factor | James Hardie | LP SmartSide | Nichiha (NichiProducts) |
|---|---|---|---|
| Material type | Fiber cement | Engineered wood | Fiber cement |
| Installed cost/sq ft | $9-$20 | $6-$12 | $8.50-$15 |
| Typical project range | $14,000-$26,000 | $12,000-$24,000 | $13,000-$23,000 |
| Substrate warranty | 30-year non-prorated | 50-year prorated (5-year full) | 30-year prorated |
| Finish warranty | 15-year (ColorPlus) | 15-year (ExpertFinish) | Primed only (no factory finish) |
| Fire rating | Noncombustible (ASTM E136) | Treated, not noncombustible | Noncombustible |
| Weight (12 ft plank) | 30+ lbs | ~19 lbs | ~28 lbs |
| Lifespan | 40-60 years | 25-40 years | 40-60 years |
| Availability | Continental US | Continental US | 13 states (Southeast/Mid-Atlantic) |
LP SmartSide shows up in every fiber cement comparison even though it’s technically engineered wood (oriented strand board with a treated overlay). Contractors quote it alongside Hardie because it fills the same niche – a step up from vinyl that looks like real wood – and the pricing overlap keeps it competitive on most bids. Nichiha’s NichiProducts line sits between the two on price, but the geographic limitation is a dealbreaker for most of the country.
Their Architectural Wall Panels occupy a different tier entirely at $18-$33/sq ft installed, targeting commercial projects and modern residential builds.
James Hardie: Product Lines and What They Cost
Hardie’s dominance translates into the widest product catalog. HardiePlank lap siding comes in six textures, two color collections, and two climate-specific formulations. That depth is part of why Hardie holds such commanding market share – contractors can match almost any aesthetic from a single manufacturer.
Textures: Select Cedarmill (wood grain), Smooth, Beaded Cedarmill, Beaded Smooth, Custom Colonial Roughsawn, and Custom Colonial Smooth. Select Cedarmill outsells all others combined because it mimics cedar lap siding convincingly from street distance.
The Statement Collection covers the standard color palette. ColorPlus Technology bakes the finish in a controlled factory environment, delivering tighter color consistency than field-applied paint.
Climate formulations: HZ5 for freeze-thaw zones (Midwest, Northeast, Mountain states). HZ10 for hot-humid regions (Gulf Coast, Southeast). Choosing the wrong formulation doesn’t void your warranty outright, but it does mean the product wasn’t optimized for your exposure conditions. Ask your contractor which formulation they’re quoting.
Beyond HardiePlank, the catalog includes HardiePanel (vertical siding, $16-$28/sq ft installed), HardieShingle (shake-style, $20-$35/sq ft installed), and HardieTrim (accent boards). Most residential re-sides use HardiePlank exclusively, with HardieTrim for corners and window casings.
The Warranty Fine Print That Matters
Warranty comparison tables look clean until you read the actual documents. Years of coverage are only half the story – what voids coverage is where these three brands diverge sharply.
James Hardie’s 30-year non-prorated warranty means full replacement value for three decades. No depreciation schedule reduces your claim over time. ColorPlus finishes carry a separate 15-year limited warranty covering peeling and chipping, including labor costs for covered repairs.
Most comparison guides skip a critical detail: Hardie’s warranty requires installation per their printed guidelines, and uncertified installation is a documented void condition. Improper fastening, inadequate expansion gaps, faulty moisture management, and non-approved paints all void coverage. An uncertified crew that nails planks tight instead of leaving the required 1/8" gap at butt joints creates a warranty-void condition that won’t surface until boards start buckling years later.
LP SmartSide’s 5/50 warranty takes a different approach. Full coverage (labor and materials) for 5 years, then the material portion prorates downward at roughly 2.2% per year through year 50. That 5-year window is generous for catching installation defects. LP also doesn’t impose the same installer certification requirements, making the warranty more accessible for homeowners using independent contractors.
Nichiha NichiProducts carry a 30-year prorated warranty with full coverage for the first 3 years, then 2% annual reduction through year 20. No factory-finish warranty exists because NichiProducts ship primed, not painted. You paint them on-site, which means your paint warranty comes from the paint manufacturer, not Nichiha.
Installer Certification: The Hidden Cost Variable
Brand selection gets most of the attention. Installer selection is where the real risk lives.
James Hardie runs the Alliance program (formerly the Contractor Alliance Program) with four tiers: Enrolled, Select, Preferred, and Elite. Alliance contractors receive hands-on training from Hardie technical specialists and undergo regular installation audits. They also get access to homeowner leads through Hardie’s contractor locator. Elite contractors sit at the top, with the most training hours and the strongest audit track record.
The certification tier affects two things that directly hit your budget:
- Warranty protection. An Alliance-certified installer means your 30-year non-prorated warranty stays intact. A general contractor who “knows how to install fiber cement” but lacks Alliance certification puts your warranty at risk. On a $20,000+ project, that’s a significant financial exposure over three decades.
- Installation quality directly affects longevity. Fiber cement is unforgiving of shortcuts – every field cut exposes raw cement that wicks moisture, and unprimed cut ends develop swelling and paint failure within 3-5 years. Certified crews carry touch-up primer on their tool belts and seal every cut edge before it goes on the wall. They flash window penetrations correctly, leave proper expansion gaps at butt joints, and back-prime any cut piece longer than 6 inches. Non-certified crews routinely skip one or more of these steps.
LP SmartSide doesn’t impose comparable certification requirements. Any licensed, insured contractor can install it without affecting warranty status. This makes LP SmartSide the more practical choice when Alliance-certified Hardie installers aren’t available in your area, or when their premium pricing pushes the project over budget.
Cost Factors Beyond the Per-Square-Foot Number
The $9-$20 range for fiber cement hides real variation driven by project specifics.
Existing siding removal adds $0.50-$1.50/sq ft. Pulling vinyl is fast and cheap. Removing old wood siding or stucco takes longer and may reveal sheathing damage underneath.
Sheathing is the hidden budget risk. Repair runs $2-$5/sq ft for affected areas, and fiber cement weighs roughly 3 lbs per square foot (about 5 times heavier than vinyl). Sheathing that held up fine under lightweight vinyl panels won’t necessarily carry that load. Any soft spots need fixing before the first plank goes up.
Repainting is the long-term cost most buyers underestimate. ColorPlus factory finish lasts 15+ years before needing a fresh coat; field-painted fiber cement needs one every 10-15 years. Budget $3,000-$6,000 per repaint on a 2,000 sq ft home – over a 50-year ownership period, that’s 3-4 cycles adding $9,000-$24,000 to lifecycle cost. See our exterior painting cost guide for regional pricing.
Two-story labor premium is real. Fiber cement’s weight makes second-story work slower and more equipment-intensive than vinyl. Expect 20-30% higher labor costs compared to single-story ranches with equivalent wall area.
| Cost Component | Per Sq Ft | Notes |
|---|---|---|
| Materials (HardiePlank, mid-range) | $4-$7 | Statement Collection, ColorPlus |
| Labor (certified installer) | $4-$8 | Higher for complex geometry |
| Old siding removal | $0.50-$1.50 | Varies by existing material |
| Trim, flashing, accessories | $1-$3 | J-channel, corner boards, starter strip |
| Sheathing repair (if needed) | $2-$5 | Budget 10-15% contingency |
Should You Pick Fiber Cement or Vinyl?
The cost gap between fiber cement and vinyl narrows when you stop comparing sticker prices and start comparing annual cost of ownership.
Divide total project cost by expected lifespan: a midrange fiber cement job runs about $400/year ($20,000 over 50 years). Vinyl’s annual cost looks comparable on paper, but a $13,000 vinyl job over 25 years comes to $520/year because the shorter lifespan compresses the same spend into fewer years. Homeowners staying 15+ years come out ahead on fiber cement; those selling within 10 years get better ROI from vinyl at $5-$12/sq ft .
Fiber cement also recovers approximately 114% of project cost at resale vs 97% for vinyl. On a $20,000 fiber cement job, that’s $22,800 back at sale versus roughly $12,600 from a $13,000 vinyl project. The gap matters most on higher-value homes, where buyers scrutinize exterior finishes more closely.

Choosing the Right Brand for Your Project
Skip the brand loyalty debates. Match the brand to your constraints:
- Fire zone or coastal climate, staying 20+ years: James Hardie. The noncombustible rating and 30-year non-prorated warranty justify the premium. Verify your installer is Alliance-certified before signing.
- Hail country, budget under $15,000: LP SmartSide. Engineered wood flexes on impact instead of chipping. The 5/50 warranty doesn’t require specific installer certification, and installed costs start at $6/sq ft vs Hardie’s $9 floor.
- Southeast/Mid-Atlantic, modern aesthetic: Nichiha. Competitive pricing, deep-texture profiles from their dry manufacturing process. Confirm your contractor has worked with Nichiha before – the clip-fastener system differs from standard lap siding installation.
- Selling within 10 years, any climate: Skip fiber cement. Vinyl at $5-$12/sq ft installed gives you acceptable curb appeal without the premium you won’t recoup on a short hold.
Ask each bidder to quote both a fiber cement and a vinyl option on the same scope of work. The price gap on your specific home may be narrower than national averages suggest – a simple 1,500 sq ft ranch might see only a $5,000 difference, while a complex two-story colonial could hit $12,000+.
