Are PVC Decks Better Than Composite Decks In Denver, CO?

The choice between PVC decks and composite decks in Denver, CO, or any other location depends on various factors, including climate, personal preferences, budget, and maintenance considerations. Here are some factors to consider when deciding between PVC and composite decking in the Denver area:


  • PVC: PVC decking tends to be more resistant to moisture, making it suitable for areas with varying weather conditions. It does not absorb water, preventing issues such as warping, cracking, or rot.
  • Composite: Composite decking also has good moisture resistance, but its performance can depend on the specific formulation and brand. It generally performs well in areas with fluctuating humidity levels.

Temperature and Sun Exposure

PVC And Composite Alternatives

Homeowners seeking low maintenance and durable decking options often turn to PVC as a wood-alternative solution. Unlike traditional wood decks, PVC decking stands up well to extreme weather conditions, resists stains and fading, and won’t succumb to rot or insect damage.

Its slip-resistant surface makes it a safe choice for outdoor spaces frequented by children and pets.

Composite decking is another popular alternative that combines wood fibers with recycled plastics for an eco-friendly option. It mimics the natural look of wood without demanding constant upkeep.

Composite decks are known for their heat-resistance which comes in handy during Denver’s hot summers, making them comfortable for bare feet even on sunny days. This affordable decking option also offers a variety of colors and finishes, ensuring that homeowners can customize their outdoor living spaces to match their personal style.
