The overall range
Fiber cement siding runs roughly $5 to $14 per square foot installed nationally, spanning the different profiles the material comes in.[1]
That range sits above standard vinyl and below the highest end of natural wood, reflecting both the material's own cost and the specialized labor it requires.
Cost by profile
Plank, the most common lap-style profile, prices as low as $0.70 a foot for bare material, climbing to $4.70-$14.25 once labor is added for a full installed number.[1]
Panel-style material runs $2.50 to $15 a foot before labor, with installed totals of $6.50 to $24, and shingle-style profiles run $2 to $6 in material with installed totals of $9 to $22, the widest spread of the three.[1]
Why labor costs more here than for lighter materials
Fiber cement's weight slows handling and requires a two-person crew more often than a lightweight vinyl job, and the specific fasteners, clearances, and dust-controlled cutting covered elsewhere on this site all add time a lighter material's install doesn't require.
That added labor is baked into the per-square-foot figures above rather than showing up as a separate surprise line item on a typical bid.
The resale case for paying more upfront
Nationally, the annual Cost vs. Value Report pegs a fiber-cement re-side at $21,485 going in and $24,420 coming back out at resale, a 113.7% recoup rate that tops vinyl siding's 96.5% on a smaller upfront number.[2]
That gap is a real, published number to weigh against a lower sticker price, not a reason on its own to rule out either material for every situation.[2]
Factory-finished versus field-painted, and what it does to the bill
Factory-finished product typically costs more upfront than factory-primed material, but it sidesteps the field-painting labor and the 180-day painting deadline this site's maintenance guide walks through.
Whether that premium pencils out depends on how soon you'd otherwise be scheduling and paying for a separate paint job anyway.
What isn't included in these figures
None of the ranges above include removing old siding, replacing house wrap, or trim, soffit and fascia work, each of which is its own cost category regardless of which new material goes up.
Getting a bid that separates the fiber cement material and labor from those other line items makes it far easier to compare against a bid for a different siding material altogether.
Getting an apples-to-apples bid across profiles
Two bids naming the same material category, fiber cement, can still describe completely different products if one is plank and the other is panel or shingle, so ask each bidder to name the specific profile before comparing dollar figures.
The same discipline applies to finish: a bid for factory-primed board and a bid for factory-finished ColorPlus board aren't directly comparable until you account for the painting labor one of them still requires.
