LP SmartSide vs. Premium Vinyl vs. James Hardie: What's Best for Wisconsin?

We get this question on almost every siding estimate. Here's how we actually think about it after 25+ years of installing all three in Wisconsin's freeze-thaw climate.

LP SmartSide (engineered wood) — our usual first recommendation

• Pros: Real wood look, deep texture, takes paint beautifully, impact resistant, stays dimensionally stable through Wisconsin freeze-thaw cycles, lighter and faster to install than fiber cement (lower labor cost).
• Cons: Needs paint maintenance every 10–15 years; cut edges must be sealed properly.
• Best for: Homeowners who want a high-end wood aesthetic with strong wind, hail, and impact resistance.

Premium vinyl (insulated, thicker panels)

• Pros: Lowest maintenance — no painting, ever. Insulated panels add R-value. Excellent value. Modern colors and profiles look nothing like the warped vinyl from the 90s.
• Cons: Can crack if struck hard in deep cold; color options are baked in (no repaint).
• Best for: Owners who want set-it-and-forget-it siding at a strong price point.

James Hardie (fiber cement)

• Pros: Extremely durable, fire resistant, holds paint a long time.
• Cons: Heavy, brittle to handle, more expensive labor, and — the part most contractors won't say out loud — Wisconsin's freeze-thaw cycle is hard on fiber cement when it isn't installed perfectly. Moisture wicks into cut ends, then expands when it freezes.
• Best for: Specific architectural looks where the homeowner understands the maintenance and install precision required.

Our take

For most Southeast Wisconsin homes, LP SmartSide or premium insulated vinyl is the right call. We install Hardie when a homeowner specifically wants it, but we don't lead with it for our climate.
