The Best Decking Materials for Delaware's Climate

ProDecks Team · January 15, 2026

Delaware homeowners face a unique set of weather challenges when choosing decking materials. From humid summers and freezing winters to the occasional nor'easter, your deck needs to handle it all. Here's a comprehensive guide to help you make the best choice.

Understanding Delaware's Climate Impact on Decking

The Mid-Atlantic region experiences all four seasons with intensity. Summer temperatures regularly exceed 90°F with high humidity, while winter brings freezing temperatures, ice, and snow. Coastal areas near the Delaware Bay and River add salt air and moisture to the equation.

These conditions mean your decking material must resist:

  • Moisture absorption and rot from humidity and precipitation
  • Freeze-thaw damage from temperature cycling
  • UV degradation from intense summer sun
  • Mold and mildew from persistent dampness

Composite Decking: The Top Choice for Delaware

Composite decking has become the most popular choice among Delaware homeowners, and for good reason. Brands like Trex and TimberTech offer capped composite boards that resist moisture, fading, and staining.

Pros:

  • Less routine refinishing than wood; periodic cleaning is still needed
  • Excellent resistance to moisture, rot, and insects
  • Review the selected product’s limits and installation requirements
  • Warranty coverage, term and exclusions depend on the exact product and written terms
  • Available in a wide range of colors and wood-grain textures

Cons:

  • Higher upfront cost than pressure-treated lumber
  • Can retain heat in direct sunlight (choose lighter colors for sun-exposed decks)
  • Some lower-end products may fade over time

Best For: Delaware homeowners who want a long-lasting, low-maintenance deck. Contact ProDecks for a free composite deck estimate.

Pressure-Treated Lumber: The Budget-Friendly Classic

Pressure-treated pine remains the most affordable decking option and is widely available throughout New Castle County and the Tri-State area.

Pros:

  • Lowest upfront cost
  • Widely available at local lumber yards
  • Can be stained or painted any color
  • Treated to resist rot and insects

Cons:

  • Requires annual maintenance (staining/sealing)
  • Prone to warping, cracking, and splintering over time
  • Service life depends on exposure, installation and care
  • Chemical treatments are a concern for some homeowners

Best For: Budget-conscious homeowners willing to invest time in annual maintenance.

Cedar and Redwood: Natural Beauty

Natural wood options offer a distinctive appearance but come with specific considerations for Delaware's climate.

Pros:

  • Beautiful natural grain and color
  • Naturally resistant to rot and insects
  • Lightweight and easy to work with
  • No chemical treatments needed

Cons:

  • Expensive — especially redwood, which must be shipped from the West Coast
  • Requires regular sealing and maintenance
  • Will gray over time if not maintained
  • Softer than composite — more prone to scratching

Best For: Homeowners who love natural wood aesthetics and don't mind regular upkeep.

PVC Decking: Maximum Moisture Resistance

PVC (polyvinyl chloride) decking is 100% synthetic and offers the ultimate moisture resistance — ideal for waterfront properties along the Delaware River.

Pros:

  • Moisture performance depends on the selected product and installation
  • Keep the surface clean; organic debris can support mold or mildew
  • Requires cleaning appropriate to the selected product
  • Lightweight

Cons:

  • Most expensive option
  • Can look and feel less natural than composite
  • Expands and contracts more with temperature changes
  • Limited color options compared to composite

Best For: Waterfront properties, pool decks, and areas with extreme moisture exposure.
