Assumptions: region, siding type, house size, and crew efficiency vary; ranges reflect typical U.S. markets.
Overview Of Costs
Cost ranges for LP siding generally start lower than fiber cement, but installation time and finishing can narrow the gap. Materials for LP engineered wood run roughly $2.50–$7.50 per sq ft, depending on thickness and grade. Hardie board fiber cement commonly lands in the $3–$7 per sq ft range for materials, with installation often more time-intensive due to weight and cutting requirements. Labor tends to dominate total price for both options, with regional wage differences and crew efficiency as major price drivers.
In a typical single-family home, a mid-sized project (around 2,000–3,000 sq ft of siding) commonly falls in the $18,000–$40,000 range before taxes, permits, and finishes. The per-square-foot average can guide budgeting, but contractors may quote by square, by run, or by project due to details like window openings and corner trims.
Cost Breakdown
Understanding the components helps quantify where money goes and how decisions affect total cost.

|---|---|---|---|---|---|
| Materials | $2.50 | $4.50 | $3.00 | $7.50 | Board thickness, grain pattern, and finish |
| Labor | $2.00 | $3.50 | $3.50 | $6.00 | Installation time per panel and crew size |
| Permits | $0 | $150 | $0 | $500 | Local permit requirements |
| Delivery | $0.20 | $0.60 | $0.30 | $1.00 | Distance and access |
| Accessories | $0.25 | $0.60 | $0.40 | $1.50 | Trims, sealants, flashings |
| Waste | $0.10 | $0.40 | $0.10 | $1.00 | Off-cuts and debris removal |
| Subtotal | $5.85 | $10.00 | $7.40 | $10.00 | Assumes standard home with mid-range finishes |
Pricing Variables
Color and finish options can swing price, while board density affects install time and waste. For LP, thickness and edge profile (square vs shiplap) influence both cost and appearance. For Hardie, fiber cement thickness and optional smooth or siding texture drive price, plus the weight can impact required equipment and crew size. Sealing and caulking details also add to long-term performance and cost.
Regional Price Differences
Prices vary across regions due to labor markets, material availability, and transportation. In coastal areas with higher labor rates, total project costs can exceed inland markets by 10–25%. The Mountain West often shows mid-range pricing, while the Southeast may be cheaper due to abundant local labor. Builders may face 5–15% differences between urban and suburban sites within the same metro area.
Labor, Hours & Rates
Labor costs are typically the dominant factor in total pricing. Installation time depends on siding type: LP can go up quicker with easier nailing but may require precise edge treatments; Hardie board requires cutting and scoring with controlled dust management, often adding time and dust control costs. Typical crews are 2–4 workers, with rates ranging from $40–$95 per hour depending on region and contractor experience. For 3,000 sq ft, a mid-range crew might bill 60–120 hours total, influencing overall spend.
Ways To Save
Strategic choices can reduce upfront and long-term costs. Consider standard thickness and profile, minimize custom trims, and schedule during off-peak seasons when labor demand is lower. Material selection matters: LP may offer lower upfront prices, while Hardie board often provides longer maintenance intervals in harsher climates. Accurate waste estimation and optimized delivery routing also cut expenses.
Regional Price Differences
Three live-market snapshots illustrate typical differences. In the Northeast urban cores, expect higher labor and delivery charges, pushing costs higher by 15–25% compared with similar homes in the Midwest suburban areas. The Southwest can be competitive on materials but may incur higher cooling-related exposure costs requiring weatherproofing. The Pacific Northwest often sees elevated costs due to weatherproofing needs and local wage scales, with a narrower margin between LP and Hardie than other regions.

What Drives Price
Key drivers include climate exposure, board specifications, and installation complexity. Climate affects sealants and moisture management, while board density and profile influence cutting time and waste. Sealing, flashings, and edge treatments add ongoing maintenance considerations that can affect long-term ownership costs. Weight considerations for Hardie board may require alternative fasteners and protective gear, increasing upfront costs but potentially reducing future maintenance needs.
Maintenance & Ownership Costs
Ownership costs extend beyond initial installation. LP siding typically requires occasional staining or sealant refresh, while Hardie board is known for lower maintenance in many climates but can incur higher replacement costs if panels crack in severe weather. Over a 5-year horizon, maintenance costs may range from a few hundred to a couple thousand dollars per 1,000 sq ft, depending on warranty terms and local conditions.
