James Hardie fiber cement siding is the gold standard for Long Island homes. It resists salt air corrosion along the South Shore and North Shore waterfronts, withstands freeze-thaw cycles that crack wood and buckle vinyl, and repels the termites that remain active in Nassau and Suffolk County's mild coastal climate. Hardie publishes a detailed installation spec — fastener placement, clearances, flashing and joint treatment — and following it is what keeps the manufacturer warranty intact. We install to that spec on every project. A typical reside on a 2,000 sq ft Long Island colonial typically runs $18,000–$35,000 installed, including HardiePlank or HardieShingle materials, ColorPlus finishing, all trim, and James Hardie's 30-year non-prorated transferable product warranty. Most Nassau and Suffolk County towns require a permit for full siding replacement — our contractors pull every permit and handle all inspections. HZ5 climate formulation is standard on every Long Island Hardie install — it's specifically engineered for the Northeast's cold winters and humid summers, preventing the edge-cracking and moisture infiltration that affects standard fiber cement in coastal environments. Hardie is increasingly popular in high-density Suffolk communities like Brentwood, where homeowners tired of replacing vinyl every 20 years are making the switch to a 40-50 year material — see our Brentwood siding page for local pricing and contractor availability.

What Sets Our James Hardie Contractors Apart
HardiePlank Lap Siding (HZ5)
America's #1 brand of siding. The HZ5 climate formulation is engineered for Northeast freeze-thaw cycles and coastal humidity — standard on all Long Island installs. Available in dozens of profiles and hundreds of ColorPlus colors.
HardieShingle & HardiePanel
HardieShingle replicates cedar shake texture without the maintenance. HardiePanel vertical siding creates a bold modern farmhouse look. Both use HZ5 formulation and carry Hardie's 30-year warranty.
ColorPlus Technology
Factory-applied color baked on in multiple coats. Resists fading, cracking, and peeling for 15+ years without repainting. The ColorPlus warranty is backed by James Hardie directly — not just the installer.
Installed to the Hardie Spec
Fastener placement, clearances, flashing and joint treatment all follow Hardie's published installation instructions — the thing that keeps the 30-year warranty valid. Ask any siding contractor to show you the spec sheet before you sign.
Salt Air & Termite Resistance
Non-combustible fiber cement. Won't rot, warp, swell from humidity, or attract termites. Long Island's coastal climate is exactly why Hardie was developed — it outlasts wood and vinyl in this environment.
Nassau & Suffolk Permit Ready
Most Long Island towns require permits for full siding replacement. Town of Hempstead, Town of Oyster Bay, Town of Islip, and Town of Smithtown all have specific requirements. Our contractors know every jurisdiction and pull permits on every job.
James Hardie FAQ
Long Island's combination of coastal salt air, high humidity, nor'easter storms, and freeze-thaw cycles is exactly the environment Hardie was engineered for. The HZ5 climate formulation is specifically designed for Northeast coastal installations. Unlike vinyl, it won't melt or warp in summer heat. Unlike wood, it won't rot or attract termites. It's non-combustible, which matters for both safety and insurance premiums in fire-prone zones.
For a typical 2,000 sq ft Long Island colonial, expect $18,000–$35,000 installed. That includes HZ5 materials (HardiePlank or HardieShingle), all trim pieces (HardieTrim), ColorPlus factory finish, removal of old siding, and a 30-year warranty. Larger homes or complex profiles run toward the top of the range. We provide free, itemized written quotes for every project.
The 30-year non-prorated warranty on the fiber cement itself comes from James Hardie and travels with the product, and the ColorPlus finish is warranted separately for 15+ years. What determines whether those hold up is the installation: Hardie publishes a detailed spec covering fastener placement, clearances, flashing and joint treatment, and an install that departs from it can give Hardie grounds to deny a claim. Separately, James Hardie runs Preferred and Elite Preferred contractor programs that add an extended labor warranty — worth asking any siding contractor about, alongside their own workmanship guarantee.
ColorPlus (factory-painted) doesn't need painting for 15+ years. Primed Hardie needs site-painting after install, then touch-ups every 10-15 years. ColorPlus is worth the upfront premium for most Long Island homeowners — especially near the water where paint is exposed to salt air.
Yes, in most cases. Full siding replacement is a permitted project in Nassau and Suffolk County townships including Town of Hempstead, Town of Oyster Bay, Town of Islip, and Town of Smithtown. Permit requirements include setback checks and sometimes wind-load documentation. Our contractors handle every permit application and inspection — it's included in the job.
