Experience the LP ExpertFinish® Advantage with Signature Exteriors

At Signature Exteriors, we’re thrilled to bring homeowners and builders the next evolution in exterior siding—LP® SmartSide® ExpertFinish®. Featuring factory-applied, automotive-grade acrylic latex paint in 16 stunning colors, ExpertFinish® delivers exceptional beauty, durability, and efficiency from the moment it’s installed.

Why the Buzz Is Real:
• Prefinished for Perfection: Every board arrives factory-finished, eliminating the need for onsite painting—saving time, labor, and potential for error. 
• Seamless, Weather-Resistant Installation: Thanks to a proprietary, end-matched lap joint, there’s no need for caulking, joint molds, or flashing—streamlining installation and lowering material costs. 
• Lighter, Longer Panels: Available in 16-foot lengths and lighter than fiber cement, these panels enable faster, easier installation—one person can carry up to five boards. 
• Built for Tough Conditions: ExpertFinish siding is engineered to resist moisture, freeze/thaw cycles, fungal decay, termites, and take the impact of high winds (rated up to 200 mph)—all backed by SmartGuard® treatment. 
• Warranty That Stands Out: Comes with an industry-leading 5/15/50‑year per‑piece prorated limited warranty—same-day finish support for the first 5 years (labor & material), and long-term coverage afterward. 
• Consistent, Professional Finish: Every board maintains uniform color whether in brushed smooth or cedar texture, thanks to controlled factory application. 
• Designed to Weather the Build: No more construction delays waiting for painters or dry weather—ExpertFinish arrives ready to install.
