As a leading Trex decking distributor we receive thousand of phone calls, emails and messenger chats about Trex decking products. Below are some of the common questions we get asked about Trex decking.

What are the benefits of using Trex decking?

Trex decking is a popular choice for outdoor decks and has several benefits, including:

  1. Durability: Trex decking is made from a combination of wood fibers and recycled plastic, which makes it highly durable and resistant to rot, decay, and pests. It can withstand harsh weather conditions, including rain, snow, and UV rays, without deteriorating.
  2. Low Maintenance: Trex decking requires minimal maintenance compared to traditional wood decks. It doesn’t need staining, sealing, or painting. Cleaning is typically easy, requiring only soap and water.
  3. Longevity: Trex decking is known for its long lifespan. It often comes with warranties that can extend for 25 – 50 years, ensuring that your investment lasts for a considerable time.
  4. Environmentally Friendly: Trex decking is made from recycled materials, including plastic bags and reclaimed wood, making it an eco-friendly option. By choosing Trex, you contribute to recycling efforts and reduce the demand for new timber.
  5. Color Options: Trex offers a wide range of colors and finishes, allowing you to choose a style that complements your outdoor space. You can also select from various textures and patterns to achieve the desired look. Another popular option is using different Trex colors for boarder accents, built-in benches and so much more.
  6. Splinter-Free: Unlike traditional wood decks, Trex decking is splinter-free, making it safer for children and pets to walk on. It also remains smooth and comfortable underfoot.
  7. Fade Resistance: Trex decking is designed to resist fading and color change over time, ensuring that it maintains its appearance for years.
  8. Resistant to Termites and Mold: Trex is not susceptible to termite infestations, and its composition makes it resistant to mold and mildew growth.
  9. Customization: Trex decking can be customized to fit your specific design preferences, including curved or multi-level decks.
  10. Stain Resistance: It is less likely to stain from spills and can often be cleaned with ease.
  11. Safety: Trex decking typically has a textured surface that provides good traction, reducing the risk of slips and falls. Snow and ice can still be slippery as it will be on most surfaces. Use the recommended snow and ice melt products for Trex deck boards to avoid this.
  12. Increased Home Value: Installing Trex decking can enhance the value of your home, as potential buyers often see it as a desirable and low-maintenance feature.

While Trex decking has many advantages, it’s essential to consider your budget and personal preferences before making a decision, as it can be more expensive upfront compared to traditional wood decking materials. However, the long-term savings on maintenance costs and the environmental benefits can offset the initial investment.

Does Trex decking get hot?

Trex decking, like many other composite and PVC decking materials, can become hot when exposed to direct sunlight during hot weather. The extent to which Trex decking gets hot can vary depending on several factors:

  1. Color: Darker-colored Trex decking tends to absorb more heat from the sun compared to lighter-colored options. So, if you choose a darker shade, it may feel hotter underfoot.
  2. Location and Climate: The climate and location of your deck play a role. In regions with intense sunlight and high temperatures, any decking material, including Trex, can become quite hot. In milder climates or shaded areas, the heat may not be as much of an issue.
  3. Time of Day: The time of day also matters. Decking materials, including Trex, are more likely to be hot to the touch during the hottest parts of the day when the sun is directly overhead.

To mitigate the issue of Trex decking becoming hot, you can consider the following tips:

  1. Choose Lighter Colors: If you’re concerned about heat, opt for lighter-colored Trex decking. Lighter colors tend to absorb less heat than darker ones.
  2. Shade Structures: Installing shade structures like pergolas, umbrellas, shade sails or awnings can help reduce the amount of direct sunlight your deck receives, keeping it cooler.
  3. Regular Cleaning: Keep your Trex decking clean, as dirt and debris can absorb heat. Regular cleaning can help maintain a cooler surface.
  4. Cooling Methods: Some homeowners have experimented with cooling methods like misting systems to make their Trex decks more comfortable during hot weather.

It’s important to note that while Trex decking can get hot, it is not unique in this regard; many outdoor surfaces can become hot when exposed to direct sunlight. If you live in an area with a hot climate, it’s advisable to take precautions to make your outdoor space more comfortable during hot weather, regardless of the decking material you choose.

What are some common mistakes to avoid when installing trex decking?

Installing Trex decking requires attention to detail and proper techniques to ensure a successful and long-lasting deck. Here are some common mistakes to avoid when installing Trex decking:

  1. Inadequate Joist Spacing: Trex decking has specific requirements for joist spacing. Failing to follow these guidelines can result in sagging or warping. Make sure to consult Trex’s installation instructions for the correct spacing based on the type of decking you’re using.
  2. Inconsistent Gapping: Proper gapping between boards is crucial to allow for expansion and contraction with temperature changes. Use the recommended gap size (usually around 3/16 inch) and ensure it’s consistent throughout the installation.
  3. Incorrect Fasteners: Trex decking often requires special fasteners designed for composite materials. Using the wrong type of fasteners can lead to issues like surface splitting or raised screw heads. Follow the manufacturer’s recommendations for fasteners.
  4. Over-Tightening Screws: When attaching decking boards, avoid over-tightening screws or fasteners. Over-tightening can lead to surface damage, distortion, or warping of the boards. Use a torque-limiting screwdriver or drill to prevent this issue.
  5. Improper Ventilation: Adequate ventilation is essential to prevent moisture buildup under the deck, which can lead to mold and rot. Ensure that the framing and understructure of the deck allow for proper airflow.
  6. Not Using Blocking: Installing blocking between joists can help reduce bounce and improve the overall stability of the deck. Neglecting to add blocking may result in a less sturdy deck.
  7. Neglecting Expansion Gaps Around Perimeter: Don’t forget to leave expansion gaps around the perimeter of the deck and between the boards and any fixed objects (e.g., walls, posts, or fascia). Failure to do so can cause the deck to buckle or warp as it expands.
  8. Poorly Cut or Mitered Ends: Cutting and mitering deck boards require precision. Poorly cut or mitered ends can result in uneven gaps, exposed edges, or boards that don’t fit together correctly.
  9. Ignoring Slope for Drainage: Ensure that your deck has a slight slope away from your home to allow for proper drainage. Neglecting proper slope can lead to water pooling, which can damage the deck and the structure beneath it.
  10. Skipping Proper Preparation: Proper preparation is essential. This includes ensuring a level and stable substructure, addressing any underlying issues like rot or pests, and properly flashing the deck if it’s adjacent to your home.
  11. Not Following Manufacturer Guidelines: Trex provides specific installation guidelines for its decking products. Always refer to these guidelines and follow the manufacturer’s recommendations to ensure a successful installation.
  12. Poor Planning for Expansion: Keep in mind that composite decking materials, including Trex, expand and contract with temperature changes. Plan for this movement and follow the manufacturer’s guidance on how to accommodate expansion.

By avoiding these common mistakes and following Trex’s installation guidelines, you can ensure that your Trex decking is installed correctly and will provide you with years of enjoyment and durability.
