HardiePlank siding typically costs $8-$14 per sq ft installed, with many standard replacement projects landing around $12,000-$21,000. The HardiePlank cost depends mainly on wall area, labor rates, trim and removal needs, and the chosen siding finish.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed siding | $8 per sq ft | $11 per sq ft | $14 per sq ft | Wall area; standard installation |
| Materials only | $1.50 per sq ft | $2.75 per sq ft | $4 per sq ft | Board, finish, and typical waste |
| 1,500 sq ft of siding | $12,000 | $16,500 | $21,000 | Installation before major repairs |
| Removal and disposal | $1 per sq ft | $2 per sq ft | $4 per sq ft | May be extra, depending on existing siding |
Assumptions: U.S. pricing for standard lap siding, accessible walls, ordinary trim, and no extensive sheathing repair. Wall area—not home floor area—is used for per-square-foot estimates.
What HardiePlank costs on a typical house
For a straightforward re-side, installed HardiePlank commonly runs $8-$14 per sq ft of exterior wall, including boards, basic fastening, and installation labor. A 1,500-sq-ft siding area therefore pencils out to about $12,000-$21,000, before unusual access, extensive trim work, or structural repairs.
A practical planning figure is about $11 per sq ft installed, or $16,500 for 1,500 sq ft of wall. Actual quotes vary with local labor, product finish, layout, and whether old siding must be removed. Factory-finished boards generally cost more than primed boards, but can reduce field-painting work.
How board, crew, and removal charges shape the quote
Contractors may combine several charges into one installed rate. The following ranges show common budget components; they are not additive in every quote because some bids bundle materials and labor.
| Quote component | Typical range | What changes the charge | Pricing basis |
|---|---|---|---|
| HardiePlank boards and finish | $1.50-$4 | Primed versus factory-finished, grade, waste | Per sq ft of siding |
| Installation labor | $3-$7 | Wall height, cuts, corners, crew experience | Per sq ft of siding |
| Trim and flashing | $1-$4 | Window count, corner details, trim material | Per sq ft equivalent |
| Old siding removal | $1-$4 | Material type, layers, disposal access | Per sq ft |
| Sheathing repairs | $75-$150 | Rot extent and replacement material | Per labor hour, plus materials |
Ask whether the bid includes trim, flashing, caulking, painting, cleanup, and disposal. Comparing line items helps reveal whether a lower total leaves out work another contractor has included.
How wall height, corners, and trim change siding rates
Wall area is the starting point, but a simple rectangular home is faster to side than a house with many gables, dormers, and openings. Multiple stories, steep grade, or limited staging space can add roughly 10%-25% to labor. Complex cuts and detailed trim can also push a quote above the standard per-square-foot range.
Waste matters, too. A basic layout may need about 5%-10% extra board; intricate elevations can require 10%-15%. Window and door openings reduce net siding area, but their trim still takes labor. Replacing sheathing after discovery of rot may add several hundred to several thousand dollars, depending on the affected area.
Measure exterior wall area and list openings, stories, and trim details before comparing estimates. Assumptions: Standard lap profile and typical residential framing; actual waste depends on board lengths and layout.
How many labor hours does a HardiePlank installation take
A two- or three-person crew may need about 5-10 working days for a typical 1,500-sq-ft siding project, including removal on a straightforward house. Labor often represents roughly 35%-55% of the total, with local rates, access, and finish work affecting the final share.
Some estimates use a project price rather than an hourly charge. For comparison, a crew labor allowance of $3-$7 per sq ft is common within a standard installation budget. When bids list hours, clarify whether setup, cleanup, and punch-list work are included.
Schedule can stretch when concealed damage, weather, or custom trim interrupts installation. Confirm the expected start date, crew size, daily work area, and whether painting is included or handled separately.
Do HardiePlank prices differ by U.S. region
Local labor and contractor demand often create larger differences than the board itself. In high-cost coastal metros, installed pricing may run 15%-30% above a national midrange; rural areas with lower labor costs may come in 5%-15% below it. Freight, local disposal fees, and code requirements can offset savings in remote locations.
Compare at least three quotes from contractors working in the same local market. Check that each uses a similar wall-area measurement, product finish, removal scope, trim package, and warranty. A quote far below local competitors may exclude preparation or finishing rather than represent a true like-for-like price.
Three HardiePlank project quotes with different scopes
| Example | Scope | Estimated total | Cost basis |
|---|---|---|---|
| Small replacement | 900 sq ft, primed boards, limited removal | $8,100-$12,600 | $9-$14 per sq ft |
| Typical re-side | 1,500 sq ft, standard trim, old siding removal | $15,000-$24,000 | $10-$16 per sq ft |
| Complex two-story | 2,200 sq ft, detailed elevations, finished boards | $26,400-$39,600 | $12-$18 per sq ft |
These examples assume ordinary framing and exclude major sheathing replacement. Higher figures account for greater complexity, finish, or removal needs; local quotes may fall outside the ranges.
HardiePlank repair or full replacement for a small damaged area
Replacing a few damaged boards can cost about $300-$1,000 when access is simple, with a contractor minimum or color-matching work sometimes raising the bill. A larger localized repair may run $1,000-$3,000. Full replacement becomes more competitive when damage is widespread, boards are difficult to match, or old siding has moisture problems.
Get a repair quote before replacing an entire wall for isolated damage. Include repainting or blending in the comparison, since a small repair may leave a visible finish difference even when the new board fits correctly.
Which HardiePlank choices reduce the installed price
Keeping the existing siding is not always feasible, but leaving sound trim in place, limiting decorative upgrades, and choosing primed boards can reduce the initial quote. Primed boards usually shift some expense to field painting; compare the installed and painted total with factory-finished pricing rather than comparing board prices alone.
Clear access and early decisions on color, trim, and board profile can reduce delays and change orders. Ask contractors to price removal, repairs, and optional upgrades separately. The best savings come from comparing the same scope, not simply choosing the lowest total.
