Selecting Coastal-Friendly Decking Materials That Resist Salt Air

Homeowners along the Northern Atlantic Seaboard face unique environmental challenges, including heavy wind, rain, and saltwater exposure. At Deck Guardian, we recognize the importance of choosing decking for coastal areas specifically made to handle these harsh conditions. Research the cost and maintenance requirements before committing to any material for your home.

To help you make a decision, we’ve analyzed and compared the performance of four popular decking materials in coastal environments. Our expert assessment considers the effects of saltwater and high wind conditions on each material, providing you with the knowledge needed to make the best choice for your coastal home.

Understanding the Challenges of Coastal Environments

Salt air can be incredibly corrosive, causing significant damage to many types of decking materials. Salt can penetrate surfaces, leading to:

  • Accelerated wear and tear
  • Discoloration
  • Structural weakening
  • Corrosion
  • Rust

It’s essential to choose coastal decking materials that are resistant to salt to ensure long-term durability. Some other factors that damage decking material:

  • Humidity: Coastal areas like Cape May County, Atlantic County, Ocean County, and Monmouth County often have very high humidity levels. If the decking material is not properly treated or inherently resistant to moisture, this can lead to mold, mildew, and wood rot.
  • Wind: Strong winds can cause physical damage to the decking structure, especially if the material is not robust enough to withstand such forces. Wind can also carry abrasive particles that can scratch and erode the decking surface over time.
  • UV Exposure: Prolonged exposure to the sun’s ultraviolet (UV) rays can cause decking materials to fade and weaken. UV protection is crucial to maintaining the deck’s appearance and integrity.

Essential Features for Coastal Decking Materials

Living on the coast comes with a lot of benefits, but one of the negatives is the damage the salty ocean air can have on your property. When choosing decking materials for coastal areas, it’s important to consider features that can withstand these harsh conditions. Here are the essential features to look for:

  • Corrosion Resistance: Ensures that the decking and its components can withstand the corrosive effects of salt air, preventing rust and deterioration.
  • Moisture Resistance: This feature protects the decking from high humidity and frequent exposure to water, preventing mold, mildew, and rot.
  • UV Protection: Shields the decking from the sun’s harmful UV rays, preventing fading and weakening of the material over time.
  • Durability and Strength: Ensures the decking can handle strong winds and physical impacts without sustaining damage.
  • Low Maintenance Requirements: Reduces the need for frequent upkeep, making it easier to maintain the deck’s appearance and functionality over the years.

Best Decking Materials for Coastal Areas

Now, knowing what you know about the requirements for a reliable coastal decking material, let’s explore the best options available:

Composite Decking

Composite decking is an excellent choice for coastal areas due to its resistance to moisture, rot, and UV damage. Brands like Trex and TimberTech offer products that combine durability with low maintenance. These materials mimic the appearance of wood without the susceptibility to weathering and decay, making them a long-lasting option for your coastal deck.

PVC Decking

PVC decking, such as AZEK, is impervious to salt, water, and mold, making it ideal for coastal environments. Its synthetic composition ensures it won’t absorb moisture or suffer from the typical issues that plague natural wood. PVC decking also provides excellent UV protection, preventing fading and maintaining its aesthetic appeal over time.

Tropical Hardwoods

Tropical hardwoods like Ipe and Teak are naturally resistant to moisture and insects, making them a durable choice for coastal decking. These dense woods offer a rich, natural look and can withstand harsh weather conditions. While they require more maintenance than synthetic options, their natural beauty and longevity make them a popular choice for high-end projects.

Aluminum Decking

Aluminum decking is rust-proof and lightweight, making it a practical and modern option for coastal areas. This material is particularly suitable for sleek, contemporary designs and is easy to install. Aluminum decking is also highly durable and requires minimal maintenance, ensuring a long lifespan even in the harshest conditions.

Pressure-Treated Wood

Pressure-treated wood is treated to resist rot and insects, making it a cost-effective option for coastal decks. However, it requires regular maintenance to prevent weathering and decay. While not as durable as some synthetic options, pressure-treated wood offers a traditional look and is widely available, making it a popular choice for many homeowners.

Additional Considerations for Coastal Decks

Coastal decking material isn’t the only thing to look for when constructing a deck near the ocean. You also need to consider the type of fasteners and hardware, the design of your deck, and how you plan to maintain it. These factors play a crucial role in the longevity and performance of your deck.

  • Fasteners and Hardware: Choose corrosion-resistant options to prevent rust and deterioration.
  • Design Tips: Maximize airflow and drainage to reduce moisture buildup, which can lead to mold and rot.
  • Maintenance Tips: Regular cleaning and protective treatments are essential to maintain the deck’s appearance and structural integrity.
  • Under-Deck Storage: Utilize the space beneath your deck for storage by ensuring proper waterproofing and ventilation to protect stored items from moisture and damage.
  • Lighting: Select weather-resistant lighting fixtures designed to withstand high humidity and salt air. Proper lighting can enhance safety and aesthetics while being durable in coastal conditions.
  • Deck Furniture: Pick outdoor furniture made from materials that can withstand salt air, such as marine-grade polymer, teak, or aluminum.
  • Deck Accessories: Consider adding weather-resistant cushions, rugs, and decor items that are specifically designed for coastal environments to enhance comfort and style without compromising durability.
