Most James Hardie installations in PA and NJ fall between $10 and $16 per square foot for typical full-house re-side projects, or roughly $16,000–$45,000 for many mid-sized homes. Higher-complexity projects with heavy trim, multi-story access, or premium product selections commonly run $16–$22+ per square foot. Stucco remediation projects can exceed $50,000 and run materially higher depending on damage discovered.

In the NJ/PA market, the common installed range is $10–$16 per square foot ($1,000–$1,600 per square). Higher-complexity jobs run $16–$22+ per square foot. "Per square" is industry shorthand for 100 square feet of coverage. Final pricing depends on exterior surface area, home shape, trim package, tear-off conditions, and any wall repair needed.

Labor costs explain most of the gap. New Jersey's carpenter wage averages $38.07/hour and construction laborers $32.34/hour. Pennsylvania's carpenter average is $30.13/hour; Philadelphia County is $32.34/hour. North and Central NJ projects typically price toward the upper end of regional ranges, while inland PA prices toward the lower end. The wage spread alone doesn't fully determine the quote difference, but it's the biggest single factor.

James Hardie fiber cement is designed to last 30 to 50+ years with minimal maintenance. The substrate carries a 30-year non-prorated, transferable limited warranty. ColorPlus Technology finishes carry a 15-year limited warranty against peeling, cracking, and chipping. Real-world performance in PA, NJ, and DE typically exceeds 30 years when installed correctly.

Two manufacturer warranties: a 30-year non-prorated, transferable limited warranty on the substrate (the siding boards themselves), and a 15-year limited warranty on ColorPlus Technology finishes covering paint and labor against peeling, cracking, and chipping. Installation workmanship is separate — Exteriors by Global Home adds the Platinum+ Workmanship Warranty covering installation for as long as you own your home.

James Hardie's 2026 catalog includes HardiePlank Lap Siding (the best-seller), HardiePanel Vertical (for board & batten), HardieShingle (shake-look profiles), HardieTrim (trim and battens), the Artisan Collection (luxury, primed), and the Hardie Architectural Collection (modern panels). Color collections include the stocked Statement Collection, the made-to-order Dream Collection (~700 colors), and the Magnolia Home Collection designed with Joanna Gaines.

Stucco remediation projects in the region typically run $30,000 to $100,000+ depending on home size, the amount of underlying rot discovered, and the replacement cladding chosen. Per square foot, remediation pricing ranges $8 to $50 depending on damage extent. Pennsylvania has been called the epicenter of the stucco-failure crisis, with homes in more than 55 PA ZIP codes affected. Most homeowners replace failing stucco with James Hardie fiber cement. See our stucco remediation page →

Sometimes — but only if the underlying stucco is in genuinely sound condition with no moisture intrusion. In PA, NJ, and DE, most homes with failing stucco need full remediation: complete stucco removal, inspection of underlying sheathing and framing, repair of any rot, installation of a proper weather-resistive barrier, then new Hardie installation. Skipping remediation when moisture damage is present traps the problem and voids most warranty coverage.

For most NJ and PA homeowners, yes. The Remodeling 2025 Cost vs. Value Report shows fiber cement recoups 99.3% of cost at resale in the Middle Atlantic region (job cost $25,666, resale value $25,475), compared to 96.3% for vinyl. Fiber cement also lasts 30–50+ years versus 20–30 for vinyl, is noncombustible per ASTM E136, and holds factory-applied color far better than field-painted finishes.

Fiber cement typically costs less than premium wood siding and requires far less maintenance — no annual painting, staining, or sealing. Wood delivers authentic warmth and full custom shapes but needs ongoing upkeep in PA, NJ, and DE humidity. Hardie is also fire-resistant (ASTM E136 noncombustible), pest-resistant, and rot-resistant — three places where wood is vulnerable. The Artisan Collection delivers a premium wood-like profile without the maintenance burden.

HZ5 (HardieZone 5) is James Hardie's product formulation engineered specifically for the Northern climate zone — which covers Pennsylvania, New Jersey, and Delaware. HZ5 boards are formulated to withstand temperature fluctuations, snow, ice, freezing temperatures, and hail. Per Hardie, only Hardie siding is "Engineered for Climate" — meaning the board formulation actually changes based on which climate zone the product ships to.

Iron Gray. James Hardie named Iron Gray its 2026 Color of the Year, available in the curated Statement Collection with ColorPlus Technology finishes. The color is one of 19 stocked Statement Collection options and reflects current homeowner demand for darker, more sophisticated exterior palettes.

Elite Preferred is the highest tier in James Hardie's contractor recognition program. To earn and maintain Elite Preferred status, a contractor must demonstrate sustained Hardie installation volume, completion of advanced training, strong customer-satisfaction performance, and full compliance with Hardie's installation standards. Exteriors by Global Home holds Elite Preferred status and received both 2025 Service Excellence and President's Club recognition from James Hardie.

Not directly. Hardie fiber cement siding itself is not a high-R-value insulation product. However, a Hardie installation can dramatically improve overall wall performance when it includes new housewrap, air sealing, moisture management, and optional cavity insulation upgrades behind the new siding. If improving energy efficiency is a primary goal, ask for insulation and air-sealing scope to be added as separate line items in your estimate.

According to the Remodeling 2025 Cost vs. Value Report from Zonda Media, fiber cement siding replacement in the Middle Atlantic region recouped 99.3% of project cost at resale — among the highest-performing remodeling projects nationally. Specifically, the report shows a job cost of $25,666 with a resale value of $25,475. Vinyl siding in the same region recouped 96.3%.

Yes. James Hardie installation requires a weather-resistive barrier (WRB) — either housewrap or an integrated alternative — along with proper flashing at every penetration, corrosion-resistant fasteners, and starter strips. James Hardie's own technical guidance and ICC-ES documentation specify these as part of a code-compliant install. Any contractor pricing below these standards is leaving out scope, not saving you money.

If both are due, yes. Removing siding exposes the window frame, which is the only time you can install proper flashing around windows and convert insert windows to full-frame at much lower marginal labor. Doing windows and siding separately means paying for some of the same exterior labor twice. See our Replacement vs. New Construction guide for the full pairing math.

The only way to get an accurate quote is an in-home estimate, because pricing depends on exterior surface area (not just interior square footage), home shape and number of stories, tear-off conditions, trim package, color collection, and any underlying wall repair needed.
