Hardie Board Siding Cost: Average Prices & Cost Factors

Hardie Board is the common name for James Hardie's fiber cement siding. It is made from cement, sand, and cellulose fibers, and it is sold as lap planks, vertical panels, shingles, and board-and-batten. Homeowners choose it for its resistance to rot and pests, and for a look that can resemble wood. The total depends heavily on home size, the style you pick, and how much old siding has to come off.

The figures below come from published cost guides and carry a check date of Oct 13, 2026. Some sources price Hardie products specifically, while others price fiber cement in general, so the tables keep them apart.

Siding is priced by the square foot of wall covered. The wide spread across styles comes from the product itself: a plain primed lap plank sits at the low end, while vertical panels and premium collections cost much more.

Because the spread is so large, always ask which Hardie product a bid assumes. A quote written around basic lap siding will not match one for board-and-batten or a premium line.

Hardie is the best-known fiber cement brand, though other makers sell the same type of siding. General fiber cement figures help you cross-check a Hardie bid, since they include labor and cover several product shapes.

Labor is a major part of any siding job. Fiber cement is heavy and brittle, and installers need to cut it with specific tools and follow the manufacturer's nailing and clearance rules. Removing the old siding adds labor and disposal.

Painting is a separate consideration. Hardie sells factory-finished boards and primed boards that are painted after installation. Pre-finished boards cost more up front but save the painting labor, while primed boards give you unlimited color choice and need a painter.

Many municipalities require a permit for siding replacement. Removal and disposal is sometimes folded into the main price and sometimes billed separately, so check the line items.

• Home size: More wall area means more material and labor.
• Product style: Lap planks, vertical panels, shingles, and board-and-batten carry different prices.
• Finish: Factory-finished boards cost more than primed boards but reduce painting work.
• Existing siding: Tearing off old siding takes time and adds disposal.
• Wall condition: Rot, water damage, or poor flashing found behind old siding must be repaired before new siding goes up.
• Trim and details: Corners, window and door trim, soffits, and fascia add to the total.
• House shape: Gables, multiple stories, and many corners slow the crew.
• Region: Labor rates and material availability vary by area.

Fiber cement sits in the middle of the siding price range. It generally costs more than vinyl and less than natural stone or high-end wood.

• Vinyl: Lower cost and low maintenance, but less rigid and with fewer finish options.
• Wood: Warm look and easy to cut, but it needs regular painting or staining and can rot where water gets in.
• Fiber cement: Strong and resistant to rot and insects, heavier to install, and typically needs a trained crew.

Installation quality matters as much as the material. Fiber cement siding relies on proper flashing, caulking, and gaps at the trim to keep moisture out, so ask any bidder about their experience with it.

The sources behind this page measure different things. The Hardie-specific figure comes from a guide to Hardie products, while the other comes from a guide to fiber cement installation in general. Home sizes, product mixes, and whether removal is included may differ.

The two ranges overlap, but the Hardie-specific range runs higher at the top. A 1,500 to 2,500 square foot home with lap siding will usually sit well below a large home with premium panels. Use the tables to sanity-check bids and ask each contractor to break out materials, labor, removal, and trim.

Fiber cement siding is a job for an experienced siding contractor. The boards are heavy, cutting them creates fine dust that crews are supposed to control with proper tools and protection, and a wrong installation can trap water in the wall. Hardie's warranty depends on following its installation instructions, so ask whether the contractor is familiar with them. Confirm that the contractor holds the license your state requires, carries liability insurance and workers' compensation, and will pull the permit.

• Which Hardie product and finish does the price assume?
• Is old siding removal and disposal included?
• What will be done about the moisture barrier, flashing, and caulking?
• Is trim included, and is it fiber cement or another material?
• Does the contractor have experience with this product, and can they provide recent references?
• Who pulls the permit, and what does the workmanship warranty cover?

Collect at least three itemized bids. If the totals differ widely, the difference is usually in what each one includes.
