Questions About Decks In Mt. Juliet? Get Your Answers Here...

  1. Durability: Composite decking is highly durable and resistant to rot, decay, and insect infestations. It doesn’t warp, crack, or splinter like wood, making it ideal for outdoor use and requiring less maintenance over time.
  2. Low Maintenance: Unlike wood decking, composite decking doesn’t require staining, sealing, or painting. It’s easy to clean with just soap and water, saving you time and effort in maintenance.
  3. Longevity: Composite decking typically has a longer lifespan than wood decking, often lasting 25 years or more with proper care. This longevity can result in cost savings over the long term, as you won’t need to replace it as frequently as wood decking.
  4. Color Retention: Composite decking maintains its color and appearance better than wood decking, which can fade over time due to exposure to sunlight and weathering. Many composite decking products are designed to resist fading and UV damage.
  5. Environmentally Friendly: Composite decking is often made from recycled materials, such as recycled plastics and wood fibers, making it a more sustainable choice compared to traditional wood decking. Additionally, its long lifespan means fewer resources are needed for replacement over time.
  6. Safety: Composite decking tends to be smoother and more slip-resistant than wood decking, reducing the risk of slips and falls, especially when wet.
  7. Variety: Composite decking comes in a wide range of colors, finishes, and textures, allowing you to customize the look of your outdoor space to suit your preferences.

Composite decking is typically made from a combination of materials, each contributing to its overall properties. While the exact composition can vary depending on the manufacturer and specific product, the main components of composite decking usually include: Recycled wood fibers, recycled plastic, binding agents (such as resins or polymers), additives to enhance performance, and other misc fillers to increase strength.

The lifespan of composite decking can vary depending on factors such as the quality of the product, the manufacturer, installation methods, climate conditions, and maintenance practices. However, high-quality composite decking is generally designed to last significantly longer than traditional wood decking.

On average, composite decking can last anywhere from 25 to 30 years or more with proper care and maintenance. Some manufacturers even offer warranties ranging from 25 years to a lifetime, indicating their confidence in the durability and longevity of their products.

Yes, composite decking can be a great choice for Tennessee’s climate! Here are some reasons why composite decks are well-suited for Tennessee weather:

  3. Durability: Composite decking is highly durable and resistant to warping, cracking, and splintering.
  4. Low Maintenance: Composite decking requires minimal maintenance compared to wood decking. Regular cleaning with soap and water is usually sufficient to keep composite decks looking great.
