James Hardie fiber cement siding is the superior choice for most Franklin homeowners — delivering unmatched durability, fire resistance, and proven long-term performance.

James Hardie fiber cement siding is the superior choice for most Franklin homeowners — delivering unmatched durability, fire resistance, and proven long-term performance.

As a James Hardie Elite Preferred installer and the Only Elite Preferred™ James Hardie® Service Excellence Award Winner serving MA, NH & ME, we’ve seen firsthand how fiber cement outlasts alternatives in New England conditions.

Here’s how these premium siding options compare:

  • Material Composition — James Hardie combines cement, sand, and cellulose fibers into a product that won’t burn, rot, or attract pests. LP SmartSide uses treated wood strands that, despite treatment, remain organic material with inherent vulnerabilities over decades.
  • Fire Resistance — James Hardie is non-combustible and carries a Class A fire rating. LP SmartSide, as a wood-based product, offers lower fire resistance. For homes near wooded areas or in fire-conscious communities, fiber cement provides peace of mind.
  • Dimensional Stability — Fiber cement maintains its shape regardless of humidity changes. Wood-based products expand and contract with moisture content variations, potentially affecting paint adhesion and joint integrity over time.
  • Proven Track Record — James Hardie has been protecting homes for over 100 years with documented performance data. LP SmartSide is a newer product with less real-world longevity evidence in harsh climates.
  • Warranty Strength — James Hardie’s 30-year non-prorated substrate warranty plus 15-year ColorPlus finish warranty provides comprehensive coverage. Harvey siding colors and other premium finishes pair beautifully with Hardie’s extensive color palette.
  • Resale Value — Real estate professionals recognize James Hardie as a premium product that adds value. The brand recognition translates to buyer confidence that lesser-known alternatives don’t command.
