We install both James Hardie® fiber cement and vinyl siding, so we have no horse in this race — the right answer genuinely depends on your budget, your timeline in the home, and what you want the exterior to look like in 20 years. Here's the comparison we walk homeowners through.
The quick comparison
| Vinyl | James Hardie® | |
|---|---|---|
| Installed cost (avg. NJ home) | $9,000–$16,000 | $14,000–$25,000+ |
| Expected lifespan | 20–30 years | 40–50 years |
| Maintenance | Occasional wash | Occasional wash; repaint ~15 yrs (ColorPlus®) |
| Fire resistance | Melts at high heat | Non-combustible |
| Impact resistance | Can crack in cold | Very high |
| Warranty | Varies, often prorated | 30-yr non-prorated |
Where vinyl wins
- Upfront price. Nothing covers a whole house for less. If the budget is fixed, vinyl gets you a clean, finished exterior now.
- Zero-paint maintenance. The color runs through the material — no repaint cycle, ever.
- Fast installation. Lighter material, quicker job, less labor cost.
Where James Hardie wins
- Longevity in NJ weather. Fiber cement shrugs off freeze-thaw cycles, coastal humidity and wind-driven rain that age vinyl visibly.
- The look. Deeper wood-grain texture and crisp shadow lines — from the curb it reads like painted wood, which vinyl imitates but doesn't match.
- Fire, pests and impact. Non-combustible, termite-proof, and it doesn't crack when a baseball or hailstone hits it in January.
- Resale value. Fiber cement consistently ranks among the top exterior projects for cost recouped at sale.
The deciding questions
We ask homeowners two questions. How long are you staying? Under ten years, vinyl's lower cost usually wins the math; longer than that, Hardie's lifespan amortizes the premium. What's the house worth? On higher-value homes, the curb-appeal difference shows up directly at appraisal and sale.
One thing matters more than the material: installation quality. A well-installed vinyl job outlasts a badly-installed Hardie job — fiber cement in particular has strict manufacturer specs that must be followed for the warranty to hold.
A third piece: the trim
Whichever siding you choose, consider AZEK® PVC trim for fascia, corners and window surrounds. Trim is where water attacks first, and PVC never rots — it pairs well with both materials.
