Sometimes what your family needs most is a reason to be together a little longer, and a deck creates that space. A new deck is an investment that adds value to your home and quality to your time outdoors. Missouri weather, especially in St. Louis, can be challenging, with a range of conditions from brutal heat to heavy rain and ice, so your new deck must be built to withstand these elements. Making smart choices about materials when you install a deck saves headaches and repairs down the road. Being proactive allows you to spend more time enjoying your deck and less time maintaining it. We’ll walk through the best decking and railing materials for lasting beauty and performance in this climate. For inspiration, watch this video of a St. Louis home renovation we performed, and the stunning deck this family now enjoys!
Decking Boards
The most visible (and hardest working) part of your deck is its boards. These boards must withstand St. Louis’ dramatic temperature swings, heavy rain, and non-stop foot traffic, all while maintaining their appeal. Discover the most weather-friendly options that keep decks in St. Louis beautiful and durable, season after season.
Composite Decking
Long-lasting, low-maintenance outdoor living starts with materials engineered to resist weather and daily wear. Composite decking meets this need.
This material for decks is constructed from recycled wood fibers and plastic polymers. It’s designed to withstand moisture, rot, insects, and fading, even during St. Louis’ muggy summers and icy winters.
Composite decking boards feature a tough outer shell that protects against stains and scratches, keeping the surface fresh with just the occasional wash. No sanding, sealing, or staining needed!
That’s why the St. Louis family chose composite decking for their recent deck installation. The result was a beautiful, durable deck that stands up to local weather and looks great for years to come!
Pressure-Treated Wood
When it comes to affordability and ease of sourcing, few materials match the accessibility of lumber that has been specially treated for outdoor use. Known for its low upfront cost, pressure-treated wood allows homeowners to build larger or more elaborate decks while staying within their budget. Treated boards are widely available across the country and can be cut, stained, or painted for a truly custom look, making them a flexible option for many different deck designs.
Pressure-treated wood, however, isn’t without drawbacks. While it is enhanced to resist rot, insects, and fungal decay, it still requires consistent upkeep to preserve its appearance and longevity.
Over time, these decks can warp, crack, fade, or splinter, especially if neglected. Regular sealing or staining is a must to keep moisture, sun, and wear at bay!
Lastly, the chemicals used in treatment may be a concern for families with small children or pets. For those willing to commit to maintenance, pressure-treated wood brings a blend of value and versatility, but it may not match the longevity of more advanced decking materials.
Cedar or Redwood
Natural resilience to insects and rot makes certain decking choices stand out. Thanks to the protective oils and tannins found within the cedar and redwood boards, these options hold up beautifully even in challenging climates.
With a classic appeal, redwood’s rich, reddish-brown hues and minimal knots add an air of elegance. Meanwhile, cedar offers a lighter, welcoming tone with a distinctive, textured grain that easily blends into any outdoor setting.
Both materials promise reliability and style, but with proper care, they become truly long-lasting. Redwood often endures for 20 to 30 years, while cedar is celebrated for its adaptability and resilience in various environments. These woods remain favorites for those who appreciate lasting value and the timeless charm of natural materials underfoot.
Hardwoods
For those seeking a deck with standout strength and a luxurious appearance, tropical hardwoods like Ipe, Mahogany, and Tigerwood are top contenders. These woods boast exceptional durability.
Ipe is renowned for its extreme density and resistance to wear, rot, and insects, while Tigerwood and Mahogany also offer impressive hardness and easy maintenance compared to traditional woods.
The beauty of each species shines through magnificently. Ipe features rich brown and olive hues, Mahogany brings classic reddish tones and flowing grain, and Tigerwood stands out with dramatic striping that lives up to its name.
However, this high performance comes at a premium. Ipe is often the most expensive option, with Mahogany and Tigerwood generally costing less but still above softwoods or composite. While the initial investment for these hardwoods is significant, their 25–75 year lifespan and low maintenance needs can offer long-term value for those prioritizing durability and aesthetics.
PVC Deck Boards
For homeowners seeking the ultimate in weather protection and durability, synthetic deck boards provide a nearly worry-free solution. Made entirely from plastic polymers, these boards resist moisture, mold, and harsh conditions such as humidity or freeze-thaw cycles. These qualities make PVC deck boards particularly strong in wet or sun-exposed areas.
Unlike composites, which blend plastic with wood fibers, full PVC boards contain no organic material at all. These deck materials won’t rot, swell, or attract insects, and they’re exceptionally easy to clean.
On very sunny days, PVC decking can become quite warm underfoot, which may make it uncomfortable for bare feet or pets during peak heat. This is something to consider, especially if your deck is exposed to full sun. However, lighter colors and shade structures can help reduce heat buildup.
While the initial investment for PVC is higher than wood or standard composites, the trade-off is unmatched resistance to moisture, rot, and fading for decades of use. For anyone prioritizing effortless upkeep and lasting durability (even through harsh weather) PVC offers real peace of mind and long-term value.
Railings
A railing is a crucial safety feature on any deck, keeping family and guests secure while enjoying time outdoors. Beyond its functional role, the right railing design can bring the entire deck’s look together. A railing can serve as a subtle accent or a bold statement. With options in color, material, and form, railings can seamlessly blend in or become a standout focal point, elevating both style and practicality.
Powder-Coated Metal
For homeowners seeking strength, modern style, and peace of mind, powder-coated metal railings are a top pick. The durable powder coating protects both aluminum and steel from rust, fading, and chipping.
These railings stay looking great in any weather with almost no maintenance. Just the occasional wipe-down is enough to keep their timeless appearance.
This finish isn’t just tough. It also provides a sleek, versatile look that can blend in or stand out, depending on the design of your space.
Wood Railings
Few features match the inviting warmth and customizable style of a classic railing that’s been designed exactly to fit your vision. Whether stained for a rustic look, painted in bold colors, or carved with distinctive patterns, wood can be shaped to elevate nearly any deck design.
This timeless option harmonizes with its surroundings and takes on character as it weathers. However, it does require a bit of extra attention.
Regular cleaning and treatment of wood railings are crucial to prevent damage and maintain their beauty year after year. For those who enjoy hands-on upkeep and want to put their personal stamp on an outdoor space, a wood railing has enduring appeal and creative potential.
Cable Railings
Minimalist cable railings are ideal for decks where preserving open views and a modern vibe is a priority, using slim stainless steel lines to maximize scenery and safety. If you prefer an even more breathtaking look, glass panels with metal posts let in light and landscape without barriers. This combination creates a dramatic, high-end aesthetic that makes outdoor spaces naturally feel bigger and brighter.
Minimalist cable railings bring contemporary style and open sightlines, using sleek stainless steel for a safe, unobtrusive boundary. Glass panels with metal posts take it further, offering unobstructed views and a high-end feel that makes decks look brighter and more spacious.
