Composite Decks in Colorado: Durable, Beautiful, and Built to Last

Colorado’s harsh and unpredictable climate can be brutal on traditional wood decks. With its high-altitude sun, fluctuating temperatures, and frequent snowstorms, Colorado presents unique challenges for homeowners looking for durable outdoor living spaces. Whether you’re looking for a composite decking installation in Castle Rock or a custom deck in Parker, composite decking offers a long-lasting, low-maintenance solution to these issues.

Unlike traditional wood decks, which fade, crack, and warp over time, composite decking is engineered to resist the elements. Thus, your deck will remain beautiful for decades with minimal upkeep. Serving Highlands Ranch, Colorado Springs, and surrounding areas, ALTA Outdoor Living specializes in crafting custom composite decks that enhance your outdoor space and withstand Colorado’s harsh weather.

Benefits of Composite Decking

  • Durability: Composite decking is designed to withstand extreme weather conditions. It is engineered with wood fibers and high-density polyethylene (HDPE) or polyvinyl chloride (PVC) to create a robust material that resists weathering, mold, mildew, and decay. Products like Trex Transcend® have a high-performance outer shell that provides superior moisture and UV resistance, ensuring the decking’s integrity over time.
  • Resistance to Moisture: The advanced capped composite technology ensures that the decking boards are impervious to water absorption, unlike wood, which can absorb moisture and lead to swelling, warping, and rotting. This makes composite decking ideal for Colorado’s high humidity and snow load conditions.
  • Longevity: With proper maintenance, composite decks can last 25-50 years, significantly outlasting traditional wood decks, which typically need replacement within 10-15 years. This extended lifespan is supported by warranties from major manufacturers like TimberTech and Trex, which offer up to 50-year warranties on their products, ensuring peace of mind for homeowners.

Did you know?: Composite decking offers a strong return on investment (ROI), with homeowners recouping an average of 68.2% of the cost when adding a new composite deck.

Why Composite Decking is the Smart Choice for Colorado Homes

Choosing composite decking for your Colorado home guarantees lasting durability and ensures you won’t have to spend time and money on regular maintenance. Here’s a deeper look into why composite decking is the smart choice:

Engineered for Colorado’s Harsh Weather

UV Resistance:

  • TimberTech PRO® and Trex Transcend® decking are engineered with UV inhibitors that protect against the harsh Colorado sun.
  • Unlike traditional wood, which can bleach and fade over time, composite decking maintains its vibrant color year after year, even in intense sunlight.

Temperature Resistance:

  • Colorado’s rapid temperature swings can take a toll on traditional decking materials.
  • Composite decking expands and contracts much slower than wood, which helps reduce the risk of warping, cracking, or splitting caused by extreme temperature shifts.
  • Designed for Colorado’s climate, composite materials are built to resist swelling and cracking, ensuring a longer-lasting, more durable deck.

Moisture Resistance:

  • Whether facing rain, snow, or humidity, composite decking materials like Azek and Trex feature a fully encapsulated core.
  • This core prevents water absorption, which can lead to mold, mildew, or decay—problems commonly found with wood decks exposed to moisture.

ALTA Outdoor Living serves Colorado Springs and surrounding areas, ensuring your deck is engineered to handle the unique moisture challenges of the region so you can enjoy a long-lasting, low-maintenance deck.

Decking Material Comparison: Composite vs. Other Options

Choosing the right decking material is a big decision. Here’s how composite decking stacks up against other common choices:

Lifespan 25-50 years 10-15 years 15-25 years 30+ years
Maintenance Low (occasional wash) High (staining & sealing) Medium (staining required) Low (occasional wash)
Weather Resistance Excellent Poor (susceptible to rot) Moderate Excellent (waterproof)
Splinter-Free Yes No No Yes
Eco-Friendly Yes (recycled materials) No Somewhat No
Cost Over Time Moderate-High (long-term savings) Low upfront but high maintenance costs Medium-High High

Did You Know?

Colorado’s high-altitude sun is 25% stronger than sea level, making UV resistance essential for outdoor materials. Unlike wood, composite decking won’t bleach, crack, or weaken under intense sunlight.

Expert Tips for Designing a Long-Lasting Composite Deck

A well-designed deck increases your home’s value and enhances outdoor living. Here’s how to create a functional and visually appealing composite deck:

  • Incorporate Built-In Features – Adding built-in seating, planter boxes, and storage benches increases functionality.
  • Choose the Right Railings – Aluminum or composite railings offer a sleek, modern, durable look.
  • Add Deck Lighting – Integrated post cap lights, step lights, and recessed lighting improve safety and ambiance.
  • Think About Under-Deck Space – If your deck is elevated, an under-deck drainage system creates a dry, usable area below for storage or seating.

When to Repair or Replace Your Composite Deck

Composite decks are durable, but they aren’t invincible. Here’s how to know when to repair or consider a complete replacement:

Signs You Need a Repair

✔ Minor Scratches or Fading – Small blemishes can be fixed with a color-matching repair kit or composite deck cleaner.
✔ Loose or Warped Boards – Individual boards can often be replaced without redoing the entire deck.
✔ Mold or Staining – A gentle wash with mild soap and a soft brush removes most stains.

Signs It’s Time for a Full Replacement

❌ Structural Damage – A complete replacement is necessary if the framing or support beams are rotting or rusting.
❌ Widespread Warping or Cracking—Older composite decks, especially those made with early-generation materials, may deteriorate over time.
❌ Unstable or Wobbly Deck – If your deck feels unsafe, it’s a sign of structural failure that requires replacement.

If your deck is over 20 years old, a modern composite deck replacement may provide better durability, aesthetics, and functionality.

Composite Decks in Colorado: Durable, Beautiful, and Built to Last FAQ’s

Yes! Composite decking is ideal for Colorado’s extreme weather. It resists UV damage, moisture, and temperature swings, making it more durable than wood. Unlike traditional decks, composite materials won’t crack, splinter, or rot due to snow, sun, or rapid freeze-thaw cycles.
Although composite decking costs more upfront than wood, it pays for itself over time. Since there is no need for annual staining, sealing, or repairs, homeowners save money on maintenance while enjoying a deck that lasts twice as long as wood.
Composite decking can warm up under direct sunlight, but many brands—like Trex and TimberTech—offer heat-resistant technology to keep surfaces cooler. Choosing lighter colors, installing shade features, or adding a pergola can help manage heat absorption.
Yes, but carefully. Use a low-pressure setting (below 1,500 PSI) and a fan-tip nozzle to avoid damaging the surface. For routine cleaning, a mix of mild soap and water with a soft brush is the best way to keep your deck looking new.
