When choosing between LP SmartSide and Hardie siding, buyers typically see cost as a key factor. The main cost drivers include material price, installation labor, substrate preparation, and trim/work around openings. This article presents practical pricing in USD with clear low–average–high ranges to help budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| LP SmartSide installed (per sq ft) | $4.50 | $6.00 | $7.50 | Includes materials and standard installation; typical 1,500–2,500 sq ft homes |
| Hardie (fiber cement) installed (per sq ft) | $8.50 | $10.50 | $12.50 | Includes materials, sealer, and basic trim; labor-intensive |
| Typical total project (1,500–2,500 sq ft) | $6,750 | $16,000 | $31,250 | Broad range based on house size and region |
| Maintenance (annual, estimate) | $100 | $400 | $1,000 | Paint refresh, caulking, and sealing for exposure areas |
Overview Of Costs
Cost overview for siding replacement shows LP SmartSide as the lower-cost option and Hardie as the premium option. The per-square-foot ranges reflect material differences and installation complexity. The totals assume standard two-story single-family homes with asphalt shingles, basic trim, and standard removal of old siding. Assumptions: region, specs, labor hours.
Cost Breakdown
| Category | LP SmartSide (Low) | LP SmartSide (Average) | Hardie (Low) | Hardie (Average) | Notes |
|---|---|---|---|---|---|
| Materials | $2.25 per sq ft | $3.50 per sq ft | $5.50 per sq ft | $6.50 per sq ft | Includes siding panels, fasteners, and coatings |
| Labor | $1.75 per sq ft | $2.50 per sq ft | $3.80 per sq ft | $4.50 per sq ft | Higher for Hardie due to cutting and kiln-dried materials |
| Equipment | $0.25 per sq ft | $0.35 per sq ft | $0.45 per sq ft | $0.60 per sq ft | Includes rental of scaffolding and saws |
| Permits | $0.10 per sq ft | $0.15 per sq ft | $0.18 per sq ft | $0.30 per sq ft | Varies by jurisdiction |
| Delivery/Disposal | $0.15 per sq ft | $0.25 per sq ft | $0.25 per sq ft | $0.35 per sq ft | Waste removal and packaging |
| Contingency | $0.10 per sq ft | $0.20 per sq ft | $0.25 per sq ft | $0.40 per sq ft | Budget cushion for weather or substrate issues |
What Drives Price
Material choice, installation complexity, and local codes drive price variance. LP SmartSide typically uses engineered wood with a faster cut and lower labor time, while Hardie fiber cement requires precise cutting, additional sealants, and longer curing times. Regional labor rates, home design (gables, corners, and windows), and substrate readiness all impact final costs. Per-unit prices can swing due to climate-related weather windows and contractor availability.
Factors That Affect Price
Key factors include siding thickness, panel profile, and required finishes. For LP SmartSide, the presence of moisture-prone walls or reclaimed trims can add costs. For Hardie, thickness (7/16″ vs 5/16″) and the need for tie-back trim and proper fastener spacing add to labor and materials. Assumptions: region, specs, labor hours.
Ways To Save
Shop multiple contractors to compare bids and seek updated warranties. Consider partial replacement, such as replacing only damaged sections or using LP SmartSide on less-visible elevations. Scheduling work in off-peak seasons can yield savings, and bundled services (siding plus soffit/fascia) may reduce overall project overhead. Get a written scope and per-square-foot breakdown.
Regional Price Differences
Prices vary by market. In the Northeast, installed costs tend to skew higher due to labor rates and stricter building codes. In the Midwest, material costs may be steadier but weather constraints affect scheduling. In the Southeast, moisture management requirements can add to labor and accessories. Overall, Hardie tends to be more sensitive to regional permitting and warranty handling. Assumptions: region, specs, labor hours.
Labor & Installation Time
Labor hours per 1,000 sq ft typically range from 12–18 hours for LP SmartSide and 18–28 hours for Hardie, depending on substrate and trim complexity. A typical crew may include 2–4 installers over 2–5 days. data-formula=”labor_hours × hourly_rate”> The higher labor demand for Hardie affects total project duration and cost.
