Quick Answer: Fiber cement siding runs $200 to $470 per square (100 SF) for the material only as of 2026, with most residential jobs landing between $260 and $380 per square. Installed, expect $500 to $1,100 per square labor and material, plus a real cost for paint or prefinished upcharge. These ranges move with style, finish, thickness, and freight, so pull current quotes for your bid date.
What Drives the Price
Fiber cement is a mix of Portland cement, sand, cellulose fiber, and water, extruded and autoclaved into panels and lap boards. The cement and sand are cheap and stable, but the cellulose pulp and the energy to run the autoclave move with the market. Within that base, five things set where you land.
- Style. Standard 8.25 inch lap boards are the volume product and sit at the low end. 5.5 inch and 6.25 inch reveal boards cost a little more because you handle more pieces per square. Vertical panels, stucco texture panels, and hand scored shake run 25 to 60 percent over standard lap.
- Primed vs prefinished. Factory primed boards are the cheapest to buy but you still pay a painter on the back end. Prefinished boards from James Hardie, CertainTeed, or Allura carry a $40 to $90 per square upcharge but skip a field paint cycle and come with a 15 year color warranty. Field painting primed boards runs $1.50 to $3.00 per SF, so the upcharge often pays for itself.
- Thickness. Standard 5/16 inch (0.312) is the production grade. Thick 7/16 inch (0.437) panels for high wind and impact zones cost 15 to 25 percent more and weigh more, which adds labor.
- Texture. Smooth face is cheaper. Cedarmill, stucco, and rough sawn textures add 8 to 18 percent because the press rolls cost more to run.
- Region and freight. Fiber cement is heavy and brittle, so long haul freight is expensive. Most plants are in the southeast and midwest, so jobs in the mountain west and Pacific northwest carry a real freight premium. Buy from the closest stocking distributor, not the cheapest catalog price.
Typical Price Ranges by Type
Material only, per square (100 SF), as of 2026. Labor runs $300 to $700 per square on top depending on wall complexity, scaffold, and tear off.
- Standard 8.25 inch lap, primed, 5/16 inch: $200 to $280 per square.
- Standard lap, prefinished (ColorPlus or equivalent): $260 to $370 per square.
- 5.5 inch and 6.25 inch reveal, prefinished: $290 to $410 per square.
- Vertical panels (4x8, 4x9, 4x10), primed: $240 to $330 per sheet, about $300 to $410 per square.
- Stucco texture panels, prefinished: $340 to $470 per square.
- Individual shakes and shingles, prefinished: $360 to $520 per square.
- Trim boards (4/4 and 5/4 thickness, 1x4 to 1x12): $1.50 to $4.00 per linear foot.
Accessories add 18 to 28 percent to the panel cost. Corner boards, frieze trim, fascia, window and door casing, and starter strip all run per linear foot. A 2,000 SF house with 16 squares of siding commonly carries 600 to 900 linear feet of trim, so do not roll it into a flat allowance.
How to Calculate the Quantity You Need
Take off wall area the simple way: gross wall SF (length times height per elevation) minus windows and doors, divided by 100 equals squares. A 2,000 SF two story house typically has 1,400 to 1,800 SF of wall area, so 14 to 18 squares before waste.
Apply a 10 percent waste factor for standard lap. Bump to 12 to 15 percent for vertical panels, shakes, and board and batten profiles, since cut waste piles up at gables and openings. Fiber cement breaks if you drop it and dulls carbide blades fast, so site damage is a real line item, not a rounding error.
Count trim by the linear foot, not the square. Measure corner boards top to bottom, fascia runs, frieze boards, and window and door casing. List each on its own line in the estimate so a missed 200 foot run does not eat your margin.
How to Buy Smarter
- Get three supplier quotes for the same style, finish, and thickness. Distributor spreads on the same week run 10 to 25 percent.
- Buy prefinished when the schedule allows. The factory upcharge is usually less than a field paint bid, and you get a warranty.
- Order by the pallet, not the box. Pallet pricing drops 5 to 12 percent and keeps the bundles intact for forklift unload.
- Lock quotes for 30 to 60 days. Pulp and energy costs move, and a quote older than 60 days is a guess on a long bid.
- Match thickness to the wind zone. 7/16 inch panels in a coastal high wind area are insurance grade and prevent callbacks. Do not bid 5/16 there to win the number and lose it on the change order.
- Ask about regional textures and colors that are overstocked. Distributors discount slow moving colors 10 to 20 percent, and if the palette fits the project you save real money on first quality stock.
Where Estimators Get It Wrong
The biggest miss is leaving paint out of the fiber cement number. A primed board at $230 per square looks cheaper than a prefinished board at $320, but the field paint on the primed board runs $1.50 to $3.00 per SF ($150 to $300 per square), so the primed path usually costs more once labor is in. Compare installed cost, not panel cost.
The second miss is undercounting trim. Fiber cement trim is expensive and brittle, and a flat 10 percent allowance never covers 900 linear feet of corners, fascia, and casing. Measure the trim and price it on its own line.
The third is forgetting the install cost delta. Fiber cement is heavy, dusty, and slow to cut, and it requires special nails and a clearance gap at every joint. Labor runs 50 to 100 percent more than vinyl on the same wall, so a fiber cement bid built on vinyl labor hours will lose money on the install side.
The fourth is ignoring the joint detail. Butt joints need a 1/8 inch gap, flashing, and caulk, or they crack in the first freeze. A bid that skips the caulk and flashing allowance is a warranty claim waiting to happen, and the caulk and back flashing are real material and labor lines.
Putting It Together
For a typical 2,000 SF house with 16 squares of wall, budget $4,400 to $6,600 for prefinished 8.25 inch lap material, plus $1,100 to $2,000 in trim and accessories, plus $4,800 to $11,200 in labor. Prefinish when you can, count your trim linear feet, and carry the install detail in the bid so the joint, caulk, and blade replacement costs do not eat the job.
