LP SmartSide vs Fiber Cement Siding
Independent research · Last reviewed August 2026 · Costs are 2026 planning estimates
The short answer
Choose LP SmartSide for a lighter, cheaper-to-install engineered-wood look you'll repaint every 8–12 years. Choose fiber cement for the longest life and a non-combustible wall, if you'll pay more upfront and don't mind the weight. Both cost far less than they look.
How LP SmartSide and Fiber Cement really differ
These two are the classic upgrade matchup, and they're genuinely close — but they win for different reasons. Fiber cement's edge is durability and fire: it lasts 30–50 years and is non-combustible. LP's edge is installation and impact: it's far lighter, cuts with standard tools, installs faster and cheaper, and resists hail better. The decision usually comes down to fire risk and labor cost, not looks.
Side by side
| LP SmartSide | Fiber Cement | |
|---|---|---|
| Installed / sq ft | $8–$15.5 | $6–$14 |
| Lifespan | 20–30 yrs | 30–50 yrs |
| Repainting | ~10 yrs | ~12 yrs |
| Maintenance | Medium | Medium |
| Fire | Moderate | Non-combustible |
| Wood look | Excellent | Good |
| DIY | Moderate | Hard |
The decision, factor by factor
Cost
LP SmartSide runs about $8–$15.50/sq ft installed, fiber cement $6–$14. On paper fiber cement looks cheaper, but its labor is higher because it's heavy and slow to hang, so real quotes often land close. Over 30 years both need repainting (unless fiber cement is factory ColorPlus), so lifetime cost is similar.
Durability & lifespan
Fiber cement wins on longevity — 30–50 years vs LP's 20–30 — and it's non-combustible. LP wins on impact: its engineered-wood core resists hail and cracking better than brittle fiber cement in some tests. Both resist rot and termites when installed and maintained correctly.
Maintenance
A wash, and repainting: LP every 8–12 years, fiber cement every ~12 (or 15+ with ColorPlus). Neither is maintenance-free, but fiber cement's ColorPlus option lets you defer repainting longest. LP's wood core is less forgiving of neglect than fiber cement's cement body.
Installation
This is LP's clearest edge. It's much lighter, cuts with standard woodworking tools, and installs faster — contractors generally prefer working with it. Fiber cement is heavy, needs special shears, and produces silica dust, all of which raise labor and rule out most DIY.
Fire & climate
Fiber cement is Class A non-combustible — the right call in wildfire-prone areas, sometimes required by code. LP is moderate on fire. In freeze-thaw and coastal climates both perform well when detailed correctly; in fire country, fiber cement is the safer choice.
Which should you choose?
Choose LP SmartSide if…
- You want lower installed cost and a faster job
- Impact/hail resistance matters (LP handles it well)
- Your crew prefers a lighter, wood-workable material
- You want a strong engineered-wood grain look
Choose Fiber Cement if…
- You're in a wildfire-prone or fire-code area
- You want the longest lifespan (30–50 years)
- You'd rather defer repainting with a factory ColorPlus finish
- Weight and higher labor cost aren't a concern
The cost difference
LP SmartSide runs about $8–$15.50/sq ft installed; fiber cement about $6–$14, but fiber cement's labor is higher because it's heavier and slower to hang, so real quotes often land closer than the ranges suggest. Price both for your home, and see the full LP SmartSide and fiber cement guides.
When neither is right
If budget is the binding constraint, vinyl is far cheaper and never needs repainting. If you want the real thing and will maintain it, natural cedar beats both on authenticity. Not sure? Run the selector.

Frequently asked questions
- Is LP SmartSide cheaper than fiber cement?
- Usually yes, especially on labor — LP is lighter and faster to install. The 30-year gap is smaller.
- Which is more durable, LP SmartSide or fiber cement?
- Fiber cement lasts longer and is fire-safe; LP resists impact and hail better.
- Which looks more like real wood?
- Close — LP's grain is a touch more convincing; fiber cement holds paint and crisp lines well.
