For most homeowners, Hardie board outperforms wood siding in durability, maintenance demands, moisture resistance, and long-term value.
Wood siding requires frequent painting, staining, and caulking to stay protected — Hardie board fiber cement is engineered to handle New England weather without that ongoing upkeep. Homeowners in Rockingham County replacing deteriorating wood siding often discover water damage around window frames and behind boards that went undetected for years.
What Southern NH Homeowners Should Know About Hardie vs. Wood
- Maintenance reality: Wood siding requires frequent painting or staining, as well as caulking to maintain weather protection. Hardie board with ColorPlus Technology never needs painting after installation.
- Moisture and rot: Wood is highly susceptible to moisture intrusion, rot, and pest damage over time. Hardie board fiber cement does not rot, warp, or attract insects the way untreated or aging wood does.
- Water damage risk: Failing wood siding is one of the leading causes of water damage around window frames and wall cavities. Replacing wood with Hardie board eliminates that risk with a product built to handle sustained moisture exposure.
- Energy performance: HardieWrap, installed beneath the fiber cement boards, reduces air infiltration and cuts natural gas or heating oil consumption by 15%. Wood siding alone offers no comparable air barrier benefit.
- Paint cost avoided: Exterior painting can cost up to $12,000 per project. Local window replacement companies and siding contractors consistently note that wood maintenance costs accumulate significantly over a home’s lifetime.
- Return on investment: Fiber cement siding delivers a 121% ROI at resale, with an average national project cost of $21,500. That return is difficult to match with wood, which carries higher lifetime maintenance costs and lower durability.

Worth knowing: If your current wood siding is showing rot, peeling paint, or soft spots around windows, those are signs of deeper moisture damage worth addressing before a new install.
Bottom line: Wood has undeniable aesthetic appeal, but the long-term maintenance costs and vulnerability to moisture make it a harder case to justify for most New England homes today.
