Decking

A Homeowner’s Guide to Decking Materials for Outdoor Projects

Building a deck is one of the most popular home improvement projects, adding both aesthetic appeal and functional outdoor living space. Whether you’re expanding your home’s footprint or enhancing your backyard, the choice of decking materials plays a critical role in determining the durability, maintenance, and overall look of your deck.

In this article, we will explore a variety of decking materials, their uses, and what homeowners should consider when selecting materials for their decking project.

Decking Materials

1. Pressure-Treated Wood

Pressure-treated wood is one of the most widely used decking materials in residential construction. It is made by treating lumber with chemicals to resist decay, insects, and moisture, making it a cost-effective option for outdoor projects.

Uses:

  • Deck boards

  • Structural Framing

  • Railings

Benefits:

  • Affordable and widely available

  • Resistant to rot, Termites, and fungal decay

  • Can be stained or painted

Considerations:
Pressure-treated wood requires regular maintenance, including sealing, staining, and occasional replacement of damaged boards. Over time, it may warp, crack, or splinter if not properly maintained.

2. Cedar

Cedar is a softwood that is naturally resistant to rot, insects, and decay, making it an excellent choice for outdoor applications. Its natural beauty and fine grain make it a favorite for homeowners seeking a warm, rustic look.

Uses:

  • Deck boards

  • Railings

  • Decorative accents

Benefits:

  • Naturally resistant to weather and insects

  • Lightweight and easy to work with

  • Develops an attractive, silvery-gray patina over time

Considerations:
Cedar is more expensive than pressure-treated wood and still requires regular maintenance, including staining and sealing. Without proper care, it may lose its resistance to moisture over time.

3. Redwood

Redwood is another natural wood option that is highly resistant to moisture, insects, and decay. Known for its rich, reddish-brown color, redwood offers a luxurious and durable decking option.

Uses:

  • Deck boards

  • Railings

  • Pergolas and shade structures

Benefits:

  • Resistant to warping and shrinking

  • Long-lasting and strong

  • Naturally beautiful with a distinctive red Hue

Considerations:
Redwood is more expensive than other wood types and is typically sourced from the western United States, which may limit availability. Like cedar, it requires regular maintenance to preserve its appearance and protective qualities.

4. Composite Decking

Composite decking is made from a blend of wood fibers and recycled plastic. It is designed to mimic the appearance of natural wood without the drawbacks of warping, splintering, or frequent maintenance.

Uses:

  • Deck boards

  • Fascia boards

  • Railings

Benefits:

  • Low maintenance (no staining, sanding, or sealing required)

  • Resistant to rot, insects, and UV rays

  • Available in a wide variety of colors and finishes

Considerations:
Composite decking tends to be more expensive than natural wood materials upfront, but it may save money in the long run due to its low maintenance requirements. Some homeowners find that it doesn’t replicate the natural warmth and feel of real wood.

5. PVC Decking

PVC (Polyvinyl Chloride) decking is a synthetic material made entirely from plastic, offering excellent resistance to moisture and harsh weather conditions. PVC decking is often chosen for its durability and ease of maintenance.

Uses:

  • Deck boards

  • Railings

  • Stairs

Benefits:

  • Completely resistant to moisture and insects

  • Requires no painting or sealing

  • Lightweight and easy to install

Considerations:
PVC decking can be more expensive than composite or wood options, and some homeowners feel that it lacks the natural look and texture of wood. In very hot climates, PVC may become uncomfortably hot underfoot.

6. Aluminum Decking

Aluminum decking is a high-performance option for homeowners looking for a long-lasting, low-maintenance material. It is incredibly durable and resistant to almost all environmental factors.

Uses:

  • Deck boards

  • Balconies and elevated decks

  • Poolside decks

Benefits:

  • Lightweight and strong

  • Rust- and corrosion-resistant

  • Reflects heat, keeping it cool underfoot

Considerations:
Aluminum decking is one of the most expensive options on the market, making it less accessible for budget-conscious homeowners. However, its long lifespan and minimal maintenance make it a cost-effective choice for those looking to invest in their outdoor space.

Associated Materials

1. Deck Framing

The frame of your deck provides the structural support for the decking boards. Pressure-treated lumber is commonly used for framing, but other materials like Steel or aluminum are sometimes chosen for their strength and longevity.

Considerations:
Ensure that the framing materials you choose are compatible with your decking boards, as some composite or PVC decking may require special Fasteners and support structures.

2. Deck Fasteners

Fasteners, such as Screws, Nails, and hidden fasteners, are used to secure the decking boards to the frame. Hidden fastener systems create a seamless look by attaching boards without visible screws on the surface.

Considerations:
Choose fasteners that are corrosion-resistant, especially if you live in a coastal area or plan to use pressure-treated wood, as some metals can react with the chemicals in the wood.

3. Deck Railings

Railings are not only functional but also enhance the safety and aesthetic appeal of your deck. Common railing materials include wood, metal (aluminum or steel), glass panels, and composite materials.

Considerations:
Choose railing materials that complement the decking and suit the overall style of your home. Many homeowners opt for pre-manufactured railing systems for easier installation.
