Best Decking Material Options for Your Home

Building a deck is one of the most rewarding home improvement projects you can invest in. It adds beauty, function, and value to your property while creating the perfect place to relax, entertain, and enjoy the outdoors. But before you start imagining summer barbecues or quiet evenings watching the sunset over Cape Cod Bay, there’s one big decision to make. Choosing the right decking material.

Homeowners on the South Shore and across Cape Cod face unique challenges when it comes to decks. The salty air, shifting temperatures, and heavy seasonal use mean your decking material needs to strike a balance between durability, low maintenance, and style.

With so many options available today, ranging from traditional wood to modern composites, it’s essential to understand the pros and cons of each so you can select the best fit for your lifestyle, budget, and home design. In this guide, we’ll break down the most popular decking materials, explain their advantages and drawbacks, and share tips on how to make the right choice for your Cape Cod or South Shore home.

Why Your Decking Material Matters

Your deck isn’t just another home feature. It’s an extension of your living space. The material you choose determines not only how your deck looks, but also how it feels underfoot, how long it lasts, and how much time and money you’ll spend on maintenance.

On the South Shore and Cape Cod, where decks are constantly exposed to salty breezes, humid summers, and icy winters, the wrong choice can lead to warping, splintering, or endless upkeep. By selecting the right material upfront, you’ll save yourself stress, repair costs, and the disappointment of a deck that doesn’t live up to your expectations.

The Most Common Decking Materials

1. Pressure-Treated Wood

Pressure-treated lumber is one of the most popular and affordable decking options. It’s made from pine that has been chemically treated to resist rot, insects, and moisture. It is ideal for homeowners looking for a cost-effective option who are willing to perform routine maintenance.

Pros:

Budget-friendly compared to other materials
Widely available and easy to install
Can be stained or painted to match your home’s aesthetic

Cons:

Requires regular maintenance (cleaning, staining, sealing)
Can warp, crack, or splinter over time, especially in Cape Cod’s damp coastal environment
Shorter lifespan compared to composites or hardwoods

2. Cedar and Redwood

Naturally beautiful and resistant to decay, cedar and redwood are classic choices for decks. Their rich tones and natural oils make them stand out without the need for chemical treatments. If you’re looking for a natural, upscale wood look and are willing to maintain it, this may be the material for you.

Pros:

Naturally resistant to insects and rot
Stunning natural color and grain
Stays cooler underfoot in direct sunlight

Cons:

More expensive than pressure-treated lumber
Still requires sealing to prevent fading and moisture damage
May not withstand the salty Cape Cod air as well as composites

3. Hardwoods (Ipe, Mahogany, Teak)

Exotic hardwoods, such as ipe and mahogany, are prized for their exceptional durability and luxurious appearance. They are dense, heavy, and resistant to almost everything and are typically used in high-end projects where longevity and luxury are top priorities.

Pros:

Extremely durable and long-lasting (25+ years)
Rich, elegant appearance that enhances high-end homes
Naturally resistant to rot, insects, and moisture

Cons:

Higher upfront cost
Difficult to cut and install due to density
Still needs oiling or sealing to maintain color

4. Composite Decking

Made from a blend of wood fibers and recycled plastics, composite decking has become the go-to choice for many homeowners on Cape Cod and the South Shore. Composite decking is ideal for busy homeowners seeking a durable, low-maintenance deck that will look great for years to come.

Pros:

Low maintenance—no staining, painting, or sealing required
Resistant to rot, mold, and insects
Won’t splinter, crack, or warp like natural wood
Available in a wide range of colors and styles

Cons:

Higher initial investment than wood
Can get hot under direct sunlight
May show scratches or stains depending on the brand

5. PVC Decking

PVC decking is made entirely of plastic, offering maximum resistance to moisture, rot, and insects. It’s lightweight and often designed to mimic the look of wood. Waterfront homes or homeowners who want a deck that can withstand the harshest conditions with almost no upkeep will benefit from PVC decking.

Pros:

100% moisture-resistant—ideal for Cape Cod’s salty, damp environment
Virtually maintenance-free
Long lifespan (often backed by 25-50 year warranties)
Available in realistic wood-like finishes

Cons:

Higher cost than composites and wood
Can feel less natural than real wood
May expand and contract more in extreme temperatures

Factors to Consider When Choosing Decking for Your Cape Cod or South Shore Home

When choosing decking for your Cape Cod or South Shore home, it’s essential to consider more than just appearance. Consider the factors below carefully to ensure your deck complements your home’s design and stands up to the demands of New England’s coastal climate.

Climate Resistance — Salt air, high humidity, and seasonal storms are part of coastal living. Composite and PVC often hold up best in these conditions, but hardwoods are also an option if properly maintained.
Budget — Pressure-treated wood is the most affordable upfront, while PVC and hardwoods are the most expensive. Composites fall somewhere in the middle but often save money long-term thanks to low maintenance needs.
Maintenance Commitment — Consider how much time you’re willing to dedicate to upkeep. If you’d rather not spend your summers sanding and staining, composites and PVC may be worth the investment.
Aesthetic Goals — Do you love the natural beauty of wood, or do you prefer a sleek, modern look? Cedar and hardwoods provide timeless warmth, while composites and PVC offer versatile style options.
Longevity — A deck is an investment. If you plan to stay in your home for many years, a durable material like composite, PVC, or hardwood may be the best choice for long-term value.
