You asked three contractors for a fiber cement siding quote and got three numbers that don’t match, none of them itemized, and one of them pushed ColorPlus without explaining what it actually saves you. The confusion is real, and it costs money because the spread between Allura and Hardie ColorPlus on a 2,000 sq ft wall can run $4,000 to $8,000 once you add labor, trim, and the finish you didn’t realize you’d be paying for. Fiber cement siding is a Portland-cement, sand, and cellulose-fiber composite cladding installed at roughly $6.00 – $14.00 per square foot depending on brand, finish, and climate zone, with most homeowners landing between $11 and $20 per sq ft fully installed.
This guide breaks down what each major brand actually costs in real projects, the hidden line items that push a “good quote” past your budget, and the decision rule that picks the right brand for your climate, aesthetic, and how long you’ll stay in the home. As part of the broader siding series, it focuses on what a brand choice does to your wall’s total cost, not how to install it.

What Fiber Cement Siding Costs Per Square Foot by Brand
National installed costs for fiber cement siding cluster between $6 and $14 per square foot, but that single number hides a $4 – $8 spread between brands and finishes that matters on a 1,800 sq ft wall. Material alone runs $2.50 – $5.00 per sq ft at most home improvement retailers; labor and accessories account for the rest, and that ratio is where brand reputation, finish choice, and crew training quietly move the total. The table below reflects recent project data for a typical single-family re-side.
| Brand | Material ($/sq ft) | Installed ($/sq ft) | 2,000 sq ft project |
|---|---|---|---|
| Allura (Ply Gem) | $2.50 – $4.50 | $6.00 – $10.00 | $12,000 – $20,000 |
| James Hardie (primed) | $3.00 – $5.00 | $6.50 – $11.00 | $13,000 – $22,000 |
| James Hardie (ColorPlus) | $4.00 – $6.50 | $8.00 – $14.00 | $16,000 – $28,000 |
| Nichiha (architectural panels) | $4.50 – $7.00 | $7.00 – $12.00 | $14,000 – $24,000 |
| GAF WeatherSide / CertainTeed | $2.00 – $3.50 | $5.50 – $9.00 | $11,000 – $18,000 |
California coastal markets add roughly $1 – $3 per sq ft to labor, so an Allura project that runs $9/sq ft inland lands near $11 – $12/sq ft in the Bay Area. The range a contractor gives you over the phone usually sits in the middle of these bands, which is why getting an itemized quote changes which brand you can afford.
The Five Major Brands: How They Differ in Practice
All five brands sell the same basic composite, but their warranty structure, installer network, and aesthetic catalog vary in ways that show up on your final invoice. Here’s what each is actually known for once you move past the marketing.
James Hardie is the 800-pound gorilla, with the deepest installer network (Hardie Preferred Contractors) and the only brand that publishes climate-specific formulations. HardiePlank in HZ10 climate-zone specification is engineered for cold, wet, and freeze-thaw exposure, while HZ5 targets hot, humid southern conditions. The ColorPlus factory finish carries a 15-year paint warranty, which is the main reason brand-loyal homeowners pay a $2 – $4/sq ft premium over primed. The trade-off: a Hardie quote tends to include brand-specific trim and flashing accessories that competitors can skip, and uninstalling in 30 years is harder because the warranty transfers less cleanly than people assume.
Allura (owned by Ply Gem) is the value play. Material pricing sits 15 – 25% below Hardie ColorPlus on most orders, the product line covers the same lap, shingle, and panel profiles, and the 30-year transferable warranty is competitive on paper. The catch is installer familiarity; many crews have done one Allura job for every ten Hardie jobs, so labor can be less efficient on a first project. Allura is a strong pick when material cost is the constraint and finish color can be matched with a quality field paint.
Nichiha earns its keep on modern and architect-led projects where the brief calls for large-format architectural panels, deep reveals, or ribbed textures rather than traditional lap siding. Material runs premium, the product is sold through specialty distributors rather than big-box stores, and not every region has a Nichiha-trained crew. Choose Nichiha when the design intent specifies it, not as a general-purpose substitute.
GAF WeatherSide and CertainTeed round out the field as budget fiber-cement options. WeatherSide targets shed-and-outbuilding use with a thinner profile; CertainTeed’s weatherboards compete on price for primary residences where a full Hardie quote is over budget. Both work, neither has the resale recognition of Hardie in buyers’ minds, and warranty terms are shorter.
What Changes the Price You Actually Pay
The number on the quote is built from five levers, and understanding them lets you negotiate or substitute where it makes sense. Most re-side projects are decided on three of these: profile, finish, and the climate zone your home sits in.
Profile drives both material cost and labor time. Standard lap siding (the most common 8.25″ exposure plank) is the cheapest to install because crews are fastest on it. Shingle and scallop profiles add 10 – 20% to labor because cuts are slower and waste runs higher. Architectural panels from Nichiha and Hardie’s Aspyre line flip that, charging more per panel but installing faster per square foot once the crew is trained.
Finish choice is where most of the visible cost lives. ColorPlus factory finish adds $2 – $4 per sq ft to material but eliminates on-site painting ($2 – $5/sq ft) and the repaint cycle that hits every 7 – 15 years on field-painted fiber cement. Over a 30-year hold, ColorPlus tends to break even or beat field paint on a primary residence, but it loses that math on a rental where turnover costs matter more than long-term appearance.
Climate zone shifts the product, not just the price. In HZ10 territory (cold, wet, freeze-thaw, and most of the northern half of the country), Hardie’s HZ10 formulation adds $0.25 – $0.50 per sq ft over equivalent HZ5 product because the formulation uses different additives. Allura and Nichiha sell a single formulation rated for similar exposure ranges, so the climate premium is largely a Hardie-specific line item.
Coastal labor markets add a separate $1 – $3 per sq ft on top of brand pricing. SF Bay Area, Seattle metro, and parts of Southern California run 25 – 35% higher labor rates than the national median, which compresses the relative savings of choosing Allura over Hardie once labor is equalized. Finally, contractor training matters: a Hardie Preferred Contractor has typically invested in factory training and installs more cleanly, but they may quote 5 – 10% higher than a general siding crew without that credential for the same job.
Where Cheap Fiber Cement Gets Expensive: Hidden Costs to Budget
The square-foot number on a quote covers the wall surface, not the project. A realistic budget adds 20 – 40% on top of wall area for the line items contractors often list separately or fold in without itemizing. Here’s where the gap between “quote” and “final invoice” actually opens up.
Old siding removal runs $1,000 – $4,000 on a typical single-family home, more if there’s a second layer, asbestos risk, or extensive rot underneath. Some contractors include this in their wall-area price, others list it as a separate line; if your quote doesn’t mention it, ask, because the discovery mid-project that someone has to pay for it usually lands on the homeowner.
Trim, soffits, and fascia are the most commonly underestimated line item. Fiber cement trim boards cost roughly twice what PVC or wood trim costs per linear foot, and a 2,000 sq ft home has 300 – 600 linear feet of trim that needs replacement or covering. Allura and Hardie sell matching trim, Nichiha often requires a separate reveal system. Budget 20 – 30% on top of wall area for trim-and-accessories if the quote looks tight.
Contractor training and warranty registration create a real but indirect cost difference. Hardie offers a 30-year non-prorated warranty when installed by a Preferred Contractor, but the field-painted line below it drops to a prorated schedule. Allura’s warranty transfers fully regardless of installer. The price you pay for the warranty difference is built into the brand premium, not a separate line.
Repaint cycles are the long tail most homeowners forget. Field-painted fiber cement needs a quality repaint every 7 – 15 years at $3 – $7 per sq ft of wall area, which over a 30-year hold adds $9,000 – $21,000 to total ownership. ColorPlus pushes that cycle out to 15 – 25 years and counts as one of the few upgrades that reliably pays back its upfront premium on a primary residence.
Which Brand to Pick for Your Project
Brand selection comes down to what you’re optimizing for: lowest material cost, longest hold, easiest resale, or a specific aesthetic. The decision rule below is written for the four situations readers actually face.
Decision Guidance
- Choose James Hardie ColorPlus for a long-term primary residence when you value a familiar resale profile, climate-specific products, and a low-maintenance factory finish.
- Choose primed James Hardie when your budget is moderate, your installer is experienced, and you plan to field-paint the final color.
- Choose Allura when material savings matter most and you have a contractor familiar with its details, trim, and flashing requirements.
- Choose Nichiha when large-format architectural panels, deep reveals, or a distinctive modern profile are central to the design.
- Choose GAF WeatherSide or CertainTeed for a lower-cost re-side, outbuilding, or price-sensitive project where brand recognition and warranty length matter less.
For the best balance, get three itemized quotes using the same profile, finish, trim scope, removal terms, and climate-zone specification. Compare the total installed price – not just the per-square-foot material number – and check that each contractor identifies the exact product, warranty registration process, accessories, and repaint assumptions in writing.
