Best Decking Materials for Coastal Areas

If you’re lucky enough to have a deck with stunning ocean views or the soothing sound of waves in your backyard, you know that life on the coast comes with some unique challenges for your outdoor space. Choosing the right decking material is essential to create a long-lasting, low-maintenance deck that can stand up to the harsh coastal environment. In this post, we’ll explore the key challenges of coastal decking and reveal the top materials that offer durability, resilience, and lasting beauty.

Key Challenges for Decking in Coastal Areas

Salt Air Exposure

One of the biggest threats to decks in coastal areas is the constant exposure to salt in the air. Over time, salt can corrode certain materials, leading to unsightly damage and compromising the structural integrity of your deck. Choosing a decking material that resists salt corrosion is crucial for a long-lasting coastal deck.

High Humidity and Moisture

Coastal areas are notorious for high humidity levels and frequent moisture from sea spray, fog, and rain. This persistent dampness can cause some decking materials to warp, split, or rot over time. To avoid these issues, look for materials that can withstand constant moisture exposure without deteriorating.

Intense Sunlight and UV Damage

Many coastal decks are subject to intense, direct sunlight for much of the day. This prolonged UV exposure can fade colors, degrade certain materials, and cause surfaces to become uncomfortably hot. Selecting a UV-resistant decking material that maintains its color and stays cooler underfoot is key for coastal areas.

Top Decking Materials for Coastal Areas

Composite Decking

Composite decking, made from a blend of wood fibers and plastic polymers, is an excellent choice for coastal homes. It resists moisture, rot, insects, and salt air corrosion while requiring minimal upkeep. High-quality composite decking, like our weather-resistant composite decking boards at Dino Decking, provides lasting durability and beauty in coastal conditions.

Pressure-Treated Wood

Pressure-treated lumber, typically made from Southern Yellow Pine, is chemically treated to resist rot, fungi, and insects. While it’s an affordable option for coastal decks, pressure-treated wood does require regular sealing and staining to maintain its appearance and protect against moisture damage.

Tropical Hardwoods (Ipe, Teak, Cumaru)

Tropical hardwoods like Ipe, Teak, and Cumaru are naturally resistant to rot, insects, and moisture damage. These dense, durable woods are well-suited for coastal environments but come with a higher price tag and the need for periodic oiling to maintain their rich color.

PVC Decking

PVC decking is entirely plastic, making it highly resistant to moisture, salt corrosion, and insect damage. It requires minimal maintenance and won’t splinter, warp, or rot. However, PVC can get quite hot underfoot in direct sunlight and may have a more artificial appearance compared to wood or composite.

Aluminum Decking

Aluminum decking is a premium option that offers excellent durability in coastal environments. It resists rust, rot, and insects while staying cool underfoot. Aluminum is lightweight yet strong, making it a great choice for rooftop decks or areas with limited support structures. The main drawback is the higher cost compared to other materials.

Factors to Consider When Choosing Decking for Coastal Areas

Maintenance Needs

Think about how much time and effort you’re willing to invest in maintaining your deck. Materials like composite and aluminum require very little upkeep, while wood decking will need more frequent cleaning, staining, and sealing to stay in top shape.

Budget

Your budget will play a role in determining the best decking material for your coastal home. Pressure-treated wood is generally the most affordable option, while composite, tropical hardwoods, and aluminum fall on the higher end of the price spectrum.

Aesthetic Preferences

Consider the overall look you want for your coastal deck. Do you prefer the natural beauty of wood grain or the clean, modern appearance of composite or aluminum? Keep in mind that some materials may fade or weather over time, affecting the aesthetics of your deck.

Tips for Maintaining a Coastal Deck

Regular Cleaning

Regardless of the decking material you choose, regular cleaning is essential to prevent the buildup of salt, dirt, and debris. Sweep your deck periodically and wash it with a mild detergent and soft-bristled brush as needed.

Sealing and Staining (for Wood Decking)

If you opt for wood decking, apply a high-quality sealer or stain every 1-2 years to protect the wood from moisture damage and UV fading. Be sure to clean the deck thoroughly before reapplying the finish.

Inspect for Damage

Regularly inspect your coastal deck for signs of damage like loose or corroded fasteners, cracked or splintered boards, or any soft spots that may indicate rot. Catching and repairing these issues early can help extend the life of your deck.

Creating a beautiful, long-lasting deck in a coastal area requires careful consideration of the unique challenges posed by the seaside environment.
