Trex Deck Problems: The Disadvantages of Composite Decking

If you are considering adding a new deck to your home, it can easily get overwhelming. Composite decking remains a great choice that many homeowners choose, but it comes with some downsides.

Trex deck problems are quite a few, but that doesn’t make it a bad material. In fact, installation issues and composite decking problems are everywhere across the industry.

In this guide, we’ll discuss the most common Trex deck problems and how to fix these issues before they become a real problem.

1. Trex decking is more expensive than traditional wood

Trex composite decking is more expensive than traditional wood, but there are several reasons why homeowners may choose to go with this option.

Composite decking is made of wood fiber and plastic, which gives it more durability than traditional wood. It is also resistant to rot and decay, making it a more long-term solution. Additionally, this type of decking doesn’t require any staining or painting, and it won’t warp or crack.

Trex decking is more expensive than a traditional wood deck has to do with the manufacturing process. Composite deck boards are made of recycled plastic and wood fibers, so the costs to fabricate them is a bit higher.

They also resist fading over time thanks to their UV protection qualities and won’t warp or crack as a wooden deck board can.

2. Trex composite decking can fade and stain over time

Trex is one of those composite decking materials that can fade and stain over time, especially if it’s overlooked.

If you notice your decking boards start to fade, clean them with a composite deck cleaner or a mixture of bleach and water. Be sure to rinse the deck thoroughly after cleaning.

If your entire deck starts to stain, you can also use a wood cleaner or a mixture of vinegar and water to remove the stains. Again, be sure to rinse the deck thoroughly after cleaning.

3. Trex decking can be damaged by weather conditions

While Trex composite decks are less susceptible to damage from weather conditions than natural wood, they are still susceptible to damage from rain and snow.

Compared to wood decking, your Trex composite decking will last for many more years, even when affected by severe weather conditions.

So, in areas with a lot of snow or ice, Trex decking is a much better option than traditional wood decking.

If weather conditions damage your composite decking, you can repair it with a Trex kit or replace the board entirely. The only downside is that finding the same composite board can be difficult.

Either way, seal any exposed edges before installing new boards.

4. Trex decking is difficult to repair or replace

Composite decking is difficult to repair or replace. If you experience any damage, you will need to use a Trex kit or replace the board entirely.

Replacing more composite decking boards on a Trex deck can be difficult, so it is important to inspect your deck regularly for any damage.

Refinishing composite decking is impossible because of its shape and patterns, so if a board gets damaged, you’ll need to replace it. And replacing is not as easy either. You don’t want to have a different board that will stick out like a sore thumb.

When you first buy your composite decking, we recommend getting several extra boards that will serve as replacements in the upcoming years.

5. Trex decking can attract bugs and pests

Composite decking can attract bugs and pests like termites, ants, and rodents. If you notice them around your composite decking, use a bug spray or insecticide to get rid of them. Rinse the deck thoroughly after spraying.

If you also have a problem with rodents on your composite decking, check the market for chemicals to repel them. It’s best to avoid doing any real harm to them.

Be sure to read the instructions carefully and follow all safety precautions.

6. Trex decking can still harm the environment

Composite decking is made of recycled materials, which, in theory, makes it environmentally friendly.

However, composite decking can sometimes contain harmful chemicals that may be harmful to the environment. If you are concerned about the environmental impact of composite decking, be sure to choose a brand that uses organic materials and ask them if their materials are safe.

Composite decking is more environmentally friendly than traditional wood simply because it uses recycled wood fibers. However, you should still be aware of the potential dangers it may pose to the environment.
