Hardie board professionally installed can last 30 years or more in Sullivan County . It’s one of the longest-lasting siding options available for New England homes.
However, the 30+ year lifespan isn’t automatic. It depends on proper installation and choosing a qualified James Hardie Elite Preferred contractor.
What Homeowners in the Dartmouth-Lake Sunapee Region Should Know About Hardie Board Longevity
- Installation is the key: A professionally installed Hardie board system can last 30 years or more. Shortcuts in flashing, fastening, or moisture barriers shorten that lifespan significantly — especially under the freeze-thaw conditions of Western NH.
- ColorPlus extends life: Hardie board with ColorPlus Technology never needs painting after installation. That means the Hardie ColorPlus colors you choose at installation stay vibrant without the repainting cycle. Repainting a house can cost $12,000 per exterior paint project.
- Color selection matters: The full range of Hardie board colors available through James Hardie Elite Preferred contractors includes over 30 options across HardiePlank®, HardiePanel®, and HardieShingle® profiles. Your installer helps match color to your home’s architecture and the regional aesthetic common in the Upper Valley.
- Energy performance adds value: HardieWrap will reduce heat loss through the wood studs of your home. That performance layer contributes to the product’s long-term value and helps protect the wall assembly behind the siding.
- Non-combustible protection: Hardie board is a non-combustible product — it won’t rot, attract insects, or contribute to flame spread. These properties remain consistent throughout the product’s full service life, regardless of age.
- Strong ROI over time: Fiber cement siding delivers a 144% ROI nationally with an average project cost of $20,678. A 30+ year lifespan near the Vermont border means that investment works harder and longer than most exterior upgrades homeowners make.
