Hardie Plank Siding Cost in 2026: Per Square Foot, Whole House and a Simple Calculator

Hardie plank siding cost in Southwest Florida typically runs $10 to $18 per square foot of wall, installed, in 2026. That price includes tear-off of the old siding, house wrap, flashing, trim and paint. For a full re-side of a typical 1,600 to 2,200 square foot frame home, most projects land between $22,000 and $60,000. Where your house falls in that range depends mostly on wall area, trim detail, height and how much rotted sheathing is found once the old siding comes off.

If you want the bigger picture first, why fiber cement beats T1-11 and hardboard here and how it is installed for wind, read our pillar guide to Hardie board siding in Florida. This article is only about the money: what you pay for, how to estimate it and how to compare quotes.

What a James Hardie Siding Quote Includes

A James Hardie siding cost number is not just boards. A complete, apples-to-apples quote should cover:

• Tear-off and disposal of the existing siding, often T1-11, hardboard, old wood lap or vinyl.
• Sheathing and framing repair where rot or termite damage is found, ideally priced per sheet in the contract.
• Weather-resistive barrier (house wrap) with taped seams.
• Flashing at windows, doors, roof-to-wall joints (kick-out flashing) and horizontal panel joints.
• Fiber cement siding itself: lap planks, panels, shingles or a mix.
• Trim at corners, windows, doors, frieze boards and fascia.
• Caulking, primer and paint, or a factory-applied finish.
• Permit, inspections, dumpster and cleanup.

When one quote looks thousands cheaper, it usually leaves out one of those lines, most often the sheathing repair or the paint.

Hardie Siding Cost per Square Foot

Contractors price siding by the square foot of wall or by the square (100 square feet). At $10 to $18 per square foot, that is roughly $1,000 to $1,800 per square installed. Typical 2026 SWFL ranges by product:

• Lap siding (HardiePlank), primed and field painted: lower to middle of the range, about $10 to $15 per square foot.
• Lap siding with a factory finish (ColorPlus): usually middle of the range; it costs more per board but replaces the first paint job.
• Vertical panels with battens (board and batten): middle to upper range because of the batten layout and extra trim; see our guide to Hardie board and batten siding.
• Shingles and shakes: upper range, mostly used on gables and accents.

These figures are for whole walls. Small jobs cost more per square foot because setup, permits and trim work do not shrink with the area.

Hardie Siding Cost Calculator: Estimate It in Five Steps

You can get a reasonable ballpark before anyone visits. Grab a tape measure or your survey:

• Step 1. Measure the perimeter. Add up the length of every exterior wall in feet.
• Step 2. Multiply by wall height. Use 8 to 10 feet for a single story, or measure. For a two-story frame home, use the total height.
• Step 3. Add gables. For each triangular gable, multiply its width by its height and divide by 2.
• Step 4. Subtract big openings. Garage doors and large sliders count; small windows barely matter because trim around them takes labor anyway. Many estimators subtract about 10 to 15 percent for openings.
• Step 5. Multiply by $10 and by $18. That gives you a low and a high installed cost.

Example: a single-story frame home with 200 feet of perimeter and 9-foot walls has 1,800 square feet of wall. Two gables at 30 feet wide by 6 feet tall add 180. Subtract about 15 percent for openings and you have roughly 1,680 square feet, so a typical estimate of about $16,800 to $30,200 before any surprises. A larger or two-story home with 3,000 square feet of wall lands around $30,000 to $54,000. Most full re-sides we price fall inside the $22,000 to $60,000 band.

Then add a cushion, typically 10 to 15 percent, for rotted sheathing on a T1-11 or hardboard house. That is the number that surprises people most.

What Drives the Price Up or Down

• Hidden rot. Wood-based sidings often hide soft sheathing and sill plates. A per-sheet repair price in the contract keeps this honest.
• Height and access. Second stories, steep lots and lanai cages that must be worked around add labor and staging.
• Trim detail. Wide window trim, frieze boards, decorative corners and lots of openings take time.
• Profile. Lap is the most efficient; board and batten and shingles cost more.
• Finish. Field paint is cheaper up front; factory finish saves the first repaint and usually carries its own finish warranty.
• Partial vs whole house. Gables or one elevation only cost more per square foot but less overall, typically $5,000 to $25,000 for accents and gables.
• Coastal exposure. Near the Gulf, corrosion-resistant fasteners and flashing are required by the manufacturer for coastal installs and add a little cost.

Fiber Cement vs Vinyl: Is Hardie Worth the Premium?

Vinyl siding in SWFL typically runs $12,000 to $32,000 for a full house, so fiber cement is roughly 1.5 to 2 times the price. What you get for the difference:

• Durability: fiber cement does not rot, feed termites or melt near reflective glass.
• Fire resistance: fiber cement is noncombustible; vinyl is not.
• Look: deep shadow lines and crisp trim that read as painted wood.
• Repairs: a single damaged board after a storm is easy to replace and repaint.

The trade-off is painting every 10 to 15 years with field paint, often longer with factory finish. For a frame home you plan to keep, we think fiber cement is usually worth it.

The Florida Angle: Permits, Wind and HOA

Re-siding is permitted work in Charlotte, Sarasota and Lee counties. The siding must be fastened to the pattern in its Florida Product Approval for your design wind pressure, so verify the current approval for the exact product and make sure your quote reflects it. Many HOAs require approval of the profile and color before work starts, which can add a few weeks. On homes near the water, ask how the contractor handles salt-air fasteners and trim details, since that is where cheap jobs fail first.

If your project also includes stucco, fascia or new windows, bundling it under one exterior remodeling contract often saves on staging and permits.

How to Compare Siding Quotes

• Is the price for the same wall area, profile and trim on every quote?
• Is tear-off, disposal and house wrap included?
• What is the per-sheet price for rotted sheathing, and is there a cap or estimate?
• Field paint or factory finish, and how many coats?
• Which Florida Product Approval and fastening schedule apply?
• Who pulls the permit and handles HOA paperwork?

Frequently Asked Questions

How much does Hardie siding cost per square foot?

In Southwest Florida, Hardie siding typically costs $10 to $18 per square foot of wall installed in 2026, including tear-off, house wrap, trim and paint. Lap siding sits lower in the range; board and batten and shingles sit higher.

How much does it cost to side a 2,000 square foot house with Hardie board?

A 2,000 square foot home usually has 1,700 to 2,600 square feet of wall depending on height and gables. At typical prices, that is roughly $22,000 to $45,000, more for a two-story or a house with a lot of rot.

Is James Hardie more expensive than other fiber cement brands?

Prices vary by supplier and product line. Hardie is the most widely stocked fiber cement in Florida, which helps with availability and matching later repairs. Compare complete installed quotes rather than board prices alone.

Does homeowners insurance pay for new siding?

Storm damage is often covered, subject to your deductible and policy. Normal rot and wear usually are not. If a storm damaged part of the house, document it and ask your adjuster how matching is handled.

Can I save money by installing Hardie siding over old siding?

It rarely saves money in the long run. Covering T1-11 or hardboard hides rot, complicates flashing and can void warranty terms. Removing it lets the wall be repaired and wrapped properly.

Bottom Line

Plan on about $10 to $18 per square foot of wall, or $22,000 to $60,000 for most full re-sides in SWFL, then add a cushion for what is behind the old siding. Measure your walls, run the five-step calculator, and insist on quotes that price the same scope. Learn more about our siding installation work.
