- No Repainting—Ever: Wood needs fresh paint every three to five years. Hardie’s ColorPlus Technology makes that cycle disappear.
- Moisture Can’t Win: Water behind wood siding triggers rot. Fiber cement never absorbs moisture—it simply doesn’t rot.
- Pests Have No Interest: Termites and carpenter ants destroy wood. Fiber cement gives them nothing to work with.
- Fire Safety Advantage: Wood feeds flames directly. James Hardie’s Class A fire rating slows flame spread, buying your family critical evacuation time. It is not fireproof.
- 144.9% ROI: Fiber cement siding delivers a 144.9% ROI, per the Cost vs Value report. JLC Online 2025 Cost vs Value, national cost vs. value data for fiber cement siding projects. (2026)
- Historic Profile Matching: HardieShingle and HardiePlank replicate the wood look Chestnut Hill homes are known for—without any upkeep.
- No Warping or Splitting: Hardie fiber cement holds its shape through New England’s temperature swings. Wood warps, splits, and buckles.
