Protecting Your Investment: How Certified Installers Safeguard Your Deck

Why Installation Quality Matters as Much as Wood Quality

For homeowners considering a beautiful exterior hardwood deck, the quality of installation is just as critical as the quality of the wood itself.

Exterior hardwoods like Ipe, Cumaru, and Garapa are among the most durable natural building materials available. With proper installation, they can last 25 to 75 years or more. But a poorly installed deck—even with premium materials—can lead to:

• Premature warping or cupping from improper spacing and fastening
• Structural issues from inadequate substructure design
• Surface checking from incorrect finishing or lack of end-sealing
• Moisture damage from poor drainage planning

What EHCI Certification Ensures

EHCI Certified Professionals have undergone rigorous training and demonstrated proficiency in the specific challenges of exterior hardwood installation. They understand:

• Proper drainage — Hardwood decks require specific slope and gap specifications to shed water effectively
• Fastening techniques — Different species and applications require specific fastener types, pre-drilling protocols, and spacing
• Expansion and contraction — Tropical hardwoods respond to moisture changes differently than domestic softwoods, requiring specialized knowledge
• Species-specific considerations — Each hardwood species has unique working properties that affect cutting, fastening, and finishing
