Best Composite Decking for North Carolina: Top Brands Compared

Are you planning a new deck or replacing an old one in North Carolina and considering composite decking? With North Carolina's moderate climate, hot humid summers (averaging 85-95°F) and mild winters, you can enjoy your deck for about 8-10 months of the year. Choosing the right composite material is crucial for longevity and enjoyment, especially given the state's humidity and termite pressure. This guide compares top composite decking brands, considering North Carolina's unique conditions and costs.

Why Choose Composite Decking in North Carolina?

Composite decking offers significant advantages over traditional wood, especially in North Carolina's climate:

• Durability: Resists rot, decay, and insect infestation – essential with NC's significant termite presence.
• Low Maintenance: No need for staining, sealing, or painting.
• Moisture Resistance: Holds up well against North Carolina's average rainfall of 45-50 inches per year.
• Variety of Styles: Available in many colors and textures to match your home.
• Long Lifespan: Many composite decks come with 25-year or longer warranties.

Keep in mind that while composite decking is more expensive upfront, the reduced maintenance and longer lifespan often make it a more cost-effective choice in the long run. Average installed deck costs in NC range from $40-70 per square foot for composite, compared to $22-40 per square foot for pressure-treated wood.

North Carolina-Specific Decking Considerations

When choosing composite decking in North Carolina, keep these factors in mind:

• Termite Resistance: Regardless of the brand you choose, ensure proper termite treatment around your deck's foundation.

Coastal areas need highly moisture-resistant materials, while mountain regions need materials that can withstand temperature fluctuations. The Piedmont region offers the most flexibility in material choices.
