Siding · LP SmartSide
The warmth of real wood with engineered resistance to rot, impact, and moisture
LP SmartSide is engineered wood siding — real wood strands and fibers bonded together with exterior-grade resins and treated with a zinc-borate preservative that resists rot, fungal decay, and insect damage. The result is a siding product that delivers the natural wood aesthetics and workability of traditional wood siding at dramatically improved performance in moisture-prone climates. For St. Louis homeowners who want a wood-look exterior without the rot concerns, repainting demands, and maintenance intensity of natural wood, LP SmartSide is a compelling mid-range option between vinyl siding and the premium fiber-cement category. LP SmartSide carries a 5/50 limited warranty — five years on finish, 50 years on the substrate against rot, decay, and fungal damage. That 50-year substrate warranty is the product's defining commitment: LP stands behind the engineered wood's structural integrity across a half-century of service. In St. Louis's climate, where spring and fall moisture cycling stresses wood products significantly, the zinc-borate treatment and resin bonding of SmartSide material perform demonstrably better than traditional wood siding. Revolve is an LP SmartSide installer with crews trained to LP's installation requirements — the condition for maintaining the 5/50 warranty. Proper LP installation includes specific nail types, exposure settings, clearance from grade, and finish coat specifications that LP's training program covers.
Why homeowners and businesses trust Revolve
5/50 limited warranty
Five years on finish, 50 years on the substrate against rot, decay, and fungal damage. LP's 50-year substrate warranty is a meaningful commitment — and it requires certified installer installation to be honored. Revolve's installer status keeps your warranty intact.
Zinc-borate treatment — real protection
LP SmartSide's zinc-borate preservative treatment penetrates the engineered wood composite rather than just coating the surface. This means cut ends and field-drilled fastener holes are protected — not just the factory finish, but the substrate itself.
Natural wood aesthetics, engineered performance
Available in lap siding, panel siding, trim boards, and soffit — all with a natural wood-grain texture. The profile variety lets LP SmartSide serve the full exterior envelope in a coordinated system.
What we offer
LP SmartSide Lap Siding
Horizontal lap siding in 8-inch and 12-inch exposures with a natural cedar-grain texture. The most common LP SmartSide application for St. Louis residential projects.
LP SmartSide Panel Siding
4x8 and 4x9 panel siding for board-and-batten applications. Groove patterns available — a popular option for modern farmhouse and contemporary styles.
LP SmartSide Trim
Coordinated trim boards, fascia, and soffit in matching engineered wood composite. Using LP trim with LP siding maintains material compatibility and a uniform look across the exterior.
Full Tear-Off & Housewrap
We remove existing siding, repair any sheathing damage, install fresh housewrap with proper window and door flashing, then install LP SmartSide to manufacturer specification.
Factory Finish Priming
LP SmartSide ships with a factory-applied primer. We apply a quality exterior topcoat in your selected color — either in the field or through pre-finished options available for certain LP products.

Free in-home consultation to select LP SmartSide profile, color, and trim configuration. We bring samples and can photograph your home to preview options.
LP SmartSide in St. Louis: What Makes It Different from Natural Wood
LP SmartSide is manufactured from oriented strand board (OSB) technology — wood strands aligned and bonded with exterior-grade resins under heat and pressure, then treated with a zinc-borate preservative that penetrates the composite rather than just coating the surface. The manufacturing process eliminates the cellular structure and moisture pathways of natural wood that allow decay organisms and insects to establish. The result is an engineered wood product that installs and works like natural wood — it can be cut with standard wood tools, takes nails and screws like wood, accepts field-applied finishes like wood — but with dramatically improved resistance to the moisture and biological threats that compromise natural wood siding in St. Louis's climate.
The zinc-borate treatment is LP SmartSide's most important performance differentiator. Because the treatment penetrates the composite during manufacturing rather than being applied to the surface, cut ends and field-drilled fastener holes retain protection — unlike surface-treated products where field cuts expose untreated substrate. In St. Louis's installation environment, where field cuts and fastener holes are exposed to the combination of rain, humidity, and freeze-thaw cycling that accelerates moisture ingress, this penetrating treatment is a meaningful advantage.
LP SmartSide carries a 5/50 limited warranty: five years on the factory prime and engineered wood's response to finish application, and 50 years on the substrate itself against rot, decay, and fungal damage. The 50-year substrate warranty is LP's commitment that the engineering that went into SmartSide's rot resistance is not just marketing — it is backed by a half-century warranty obligation.
LP SmartSide vs. James Hardie: An Honest Comparison
The LP SmartSide versus James Hardie comparison is the most common product evaluation Revolve conducts in the St. Louis siding market. Both are excellent products appropriate for the climate. The practical differences are real and worth understanding.
James Hardie fiber cement contains no organic content — Portland cement, ground sand, and cellulose fiber produce a mineral composite that has no wood chemistry at all. This makes Hardie marginally harder and more impact-resistant than LP SmartSide and gives it a more consistent surface for the factory-applied ColorPlus finish. Hardie's 30-year substrate warranty and 15-year ColorPlus color warranty are industry-leading.
LP SmartSide is engineered wood — real wood fiber chemistry, despite the zinc-borate treatment. This makes it easier to cut, nail, and work in the field (wood tools, wood fastening methods), gives it a natural wood look and feel that many homeowners prefer over fiber cement's harder appearance, and makes it appropriate for complex millwork profiles that fiber cement handles less well. LP SmartSide also accepts field-applied stain finishes more naturally than fiber cement when a stained rather than painted finish is desired. The 50-year rot warranty is strong, though the 5-year finish warranty is shorter than Hardie's 15-year ColorPlus coverage.
For most St. Louis homeowners evaluating both products: if Class A fire rating and maximum impact resistance are priorities, Hardie wins. If natural wood aesthetics and workability in complex profiles are priorities, LP SmartSide wins. Both are correct answers for the climate.
Installation Requirements That Protect Your Warranty
LP SmartSide's 5/50 warranty is conditioned on installation to LP's published installation requirements. The critical conditions: fastener type and size (hot-dipped galvanized or stainless steel — not zinc-coated or aluminum, which corrode and stain the siding), clearance from grade (at least 6 inches above finished grade), clearance from roofline (at least 1 inch), end-cut sealing with LP SmartSide End Seal at all field cuts, joint design per LP's specification for horizontal and vertical butt joints, and a complete topcoat within 180 days of installation.
Revolve's crews are trained to LP's installation requirements and follow them on every SmartSide project. The fastener specification is the most commonly violated condition by non-certified installers — zinc-coated or electrogalvanized fasteners corrode in Missouri's moisture environment and produce visible rust staining on the siding surface within two to three years. Hot-dipped galvanized or stainless is non-negotiable for a warranty-compliant installation.
Finish Options for LP SmartSide in St. Louis
LP SmartSide ships from the factory with a primer coat applied over the engineered wood surface. A field topcoat — applied within 180 days of installation — is required to complete the weather barrier and activate the warranty. LP's primer is formulated for compatibility with standard exterior latex paints, so any quality exterior paint in the homeowner's color of choice is appropriate.
For homeowners who want a pre-finished option, LP offers SmartSide ExpertFinish — a factory-applied topcoat available in a palette of curated colors with a five-year color warranty. Factory finish provides more consistent color application and eliminates the field painting step, but limits color selection to LP's palette. For custom colors or stained finishes, field application after installation is the appropriate path. Revolve coordinates the finish application as part of the project scope and can recommend local finishing contractors for homeowners who want the topcoat handled independently.
