Hardie plank siding typically costs $7-$14 per square foot installed, with a common whole-home project landing around $14,000-$28,000. The cost of Hardie plank depends mainly on wall area, removal of existing siding, trim details, home height, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed siding | $7 per sq ft | $10 per sq ft | $14+ per sq ft | Wall area, standard access |
| Materials only | $2 per sq ft | $3.50 per sq ft | $6 per sq ft | Boards, basic trim, fasteners |
| 1,500 sq ft project | $10,500 | $15,000 | $21,000+ | Installed; excludes major repairs |
| Old siding removal | $1 per sq ft | $2 per sq ft | $4 per sq ft | Higher for layered or difficult removal |
Installed Hardie plank prices for a typical home
For a straightforward installation, homeowners often pay $7-$14 per square foot of siding-covered wall, including standard materials and labor. A 1,500-square-foot wall area therefore comes to about $10,500-$21,000 before unusual repairs, extensive trim, or premium finishes. A larger 2,000-square-foot wall area may cost $14,000-$28,000.
A practical planning average is about $10 per square foot installed, not per square foot of floor space. Contractors measure exterior wall area, subtracting some openings while accounting for waste and installation details. Assumptions: standard lap siding, ordinary access, and typical U.S. labor rates.
What labor, boards, trim, and removal add to the quote
Installed bids combine fiber-cement boards with preparation and skilled installation. Labor can be a substantial share because Hardie planks are heavier than vinyl and require careful cutting, fastening, and joint treatment. The ranges below are typical planning figures, not fixed national rates.
| Quote component | Typical range | What changes the price |
|---|---|---|
| Hardie plank boards | $2-$6 per sq ft | Finish, board profile, and color |
| Labor | $3-$7 per sq ft | Wall height, layout, and crew productivity |
| Trim and corner boards | $5-$15 per linear ft | Window count and trim width |
| Removal and disposal | $1-$4 per sq ft | Existing layers and dump fees |
| House wrap and flashing | $0.50-$2 per sq ft | Sheathing condition and water details |
Some quotes combine materials, labor, and preparation into one square-foot rate; others price trim, disposal, and repairs separately. Ask whether the estimate includes house wrap, flashing, caulking, cleanup, and disposal.
How wall height and board style change the square-foot price
Two homes with equal wall area can receive different quotes. A one-story rectangle is generally faster to side than a two-story home with steep rooflines, dormers, or limited ladder access. Moving from easy ground-level walls to second-story work can add roughly 10%-25% to labor, depending on setup and safety needs.
Board choice matters too. Smooth or primed lap siding is often less costly than factory-finished boards, while wider boards, vertical panels, shakes, and decorative trim can increase material and installation costs. Extra corners, window openings, and transitions increase cutting time even when total wall area stays the same. For example, a home with 25 or more windows may need more trim labor than a simple layout with fewer openings.
Which removal and wall repairs belong in the budget
Installing over sound existing siding may be possible in some situations, but the contractor must confirm that the surface is suitable and that local requirements are met. Removing old siding typically adds $1-$4 per square foot, with multiple layers, lead-safe procedures, or difficult disposal potentially raising the bill.
Once the wall is exposed, rotted sheathing or damaged framing can add about $2-$8 per square foot of affected area, depending on materials and access. Replacing a small section is different from repairing entire elevations. Request a written unit rate for hidden rot so a change order has a clear basis.
How regional labor rates shift Hardie siding bids
Labor and disposal rates vary by market. Dense urban areas and high-cost coastal metros may run about 15%-30% above a national planning estimate, while many rural markets may be 5%-15% below it. Local contractor availability, weather exposure, and demand can outweigh the material price difference.
For a 1,500-square-foot wall project priced at a $15,000 midpoint, a high-cost market could reach roughly $17,250-$19,500 for comparable scope. A lower-cost market might land near $12,750-$14,250. Compare bids only after confirming they cover the same wall area, trim, removal, and warranty terms.
How long a Hardie plank crew needs on site
A typical crew of three or four installers may need about 5-10 working days for a straightforward 1,500-square-foot wall project. Complex trim, extensive removal, repairs, weather delays, or a two-story layout can extend the schedule to two or three weeks. Labor rates commonly work out to roughly $50-$100 per worker-hour, though contractor pricing usually includes overhead and is not billed as a simple hourly charge.
Scheduling and access affect productivity. Clear landscaping near the walls, move outdoor furniture, and arrange access to gates or driveways before work begins. Ask for the planned crew size and estimated workdays when comparing labor-heavy bids.
Hardie plank versus vinyl siding at the same wall area
Vinyl siding commonly costs about $4-$9 per square foot installed, compared with roughly $7-$14 for standard Hardie plank. For 1,500 square feet of wall area, that difference may represent several thousand dollars upfront. Premium insulated vinyl can narrow the gap, while factory-finished fiber cement or elaborate trim can widen it.
The products differ in appearance, upkeep, and resistance to impact, moisture, and fire; installation quality and local conditions also matter. Compare total installed quotes and specified product lines rather than judging by material price alone. Ask each contractor to identify any extra underlayment, trim, or disposal charges.
Which choices can lower the final Hardie plank bill
Keep the design close to standard lap siding and limit decorative accents, complex transitions, and unusually wide trim. Choose primed boards when local painting costs make sense, but compare the full installed and finished price with factory-finished options. Bundling siding with other exterior work can reduce mobilization charges when the scopes truly overlap.
Get at least three itemized estimates using the same measured wall area and product specification. Confirm whether each bid includes removal, house wrap, flashing, painting, permits if required, and cleanup. Repair sound sheathing rather than replacing it automatically, but do not cover known moisture damage to reduce the quote.
