Composite decks have become a popular choice for homeowners in recent years. They are made of materials like wood and plastic, which gives them a natural look. They also require less maintenance than traditional decks. However, there are some trex deck problems that you should be aware of before deciding whether or not to install one for your home.

In this blog post, we will discuss the pros and cons of composite decking so that you can make an informed decision about whether or not it is the right choice for you.

Composite decks and their advantages

Composite decks are becoming popular because they offer several benefits over traditional decks. They are low-maintenance, requiring no staining or sealing, and resistant to rot, insects, and weathering, making them a durable option. Composite materials are recycled, and you can choose to build them in various colors and styles.

Comoposite deck disadvantages

Composite decks may seem like a great option because of their many benefits, but there are a few disadvantages that you should be aware of before installing one in your home.

First, composite decks can be expensive to install. They also require more cleaning and maintenance than traditional wooden decks, as they can stain and fade over time.

Additionally, composite decks may not be as durable as advertised and can be susceptible to damage from weather and insects.

Trex deck problems and how to solve them

1. Faded Color

Over time, composite decks can fade and lose their color. You can restore the deck’s color by using a deck restoration product if this happens. These products are available at most home improvement stores and work by restoring the deck’s surface.

2. Insect Damage

Insects can also damage composite decks, causing them to warp or rot. If you notice any insect damage, you can treat it using an insecticide. Insecticides are available at most home improvement stores and work by killing the insects that are causing damage to your deck.

3. Weather Damage

Weather can also cause damage to composite decks, causing them to warp, crack, or split. If your deck is damaged by weather, you can repair it using a trex deck repair kit. Composite deck repair kits are available at most home improvement stores and composite decking companies and work by repairing the damage to your deck.

4. Mold and mildew on composite deck

Mold and mildew can form on most composite decking if not properly cleaned and maintained. Mold and mildew can cause the deck to look dirty and unappealing. Additionally, it can cause the deck to become damaged and may even be harmful to your health.

To prevent these from forming on your deck, you should clean it regularly with trex decking products. Deck cleaners are available at most home improvement stores and work by removing dirt, grime, mold, and mildew from the deck’s surface.

5. Water damage on trex decking

Water damage is a common problem with composite decks. If the deck is not correctly sealed, it can become damaged by moisture and weather. Water damage can cause the deck to warp, crack, or split. Additionally, it can cause the deck to become moldy and unsightly.

To prevent water damage to your composite decking material, you should seal it every year. Sealing your deck will help protect it from moisture and weather damage. You should also clean your deck regularly with a cleaner to remove dirt and grime.

6. Snow and ice removal

Removing snow and ice from composite deck boards can be a difficult task. If not done correctly, it can damage the deck and cause water damage.

To remove snow and ice from your composite deck, you should use a snow shovel or a broom. You can also use a salt mixture to melt the snow and ice. However, be careful not to use too much salt to damage the decking.

7. Handling static electricity

Trex decks can often become staticky, especially in the winter. This is because the plastic and wood in the decking create an electrical charge.

To prevent static electricity from ruining your entire deck, you can use a grounding strap. A grounding strap is a metal strap that you attach to your body and then attach to the decking. This will help discharge the static electricity and prevent it from doing damage.

Another way to reduce static electricity is to use an anti-static spray. Anti-static sprays are available at most electronic stores and work by reducing the static charge in the air. Spraying your deck board with an anti-static spray will help keep it from becoming staticky.

Composite deck vs. wood deck

While a wood decking may require periodic painting or staining, a trex composite decking will never need to be treated with any sealant or finish. A composite deck board is also much more durable than wood deck boards, and it typically requires much less maintenance.

Composite decks can be quite slippery when wet. They also tend to fade in color over time, and some people find the appearance of composite decking boards less attractive than traditional wood decks.

Another drawback is the price tag. Composite decking is typically more expensive than traditional wood. 

It can also be challenging to find a contractor who is familiar with composite decking, so it may be necessary to hire a specialist if you decide to go with this type of decking.

Yet, composite decking is a more environmentally friendly option than traditional decks. Wood decks require forests to be cut down, while plastic can be made from recycled materials. This makes composite decking a more sustainable choice than wood.

Finally, composite decks may not be as strong as wood decks, so they may not be suitable for areas that experience a lot of heavy traffic. Overall, unlike wood, composite decks offer many advantages and are an excellent choice for an affordable, durable, and maintenance-free decking option.

Which type of deck is right for you - composite or wooden?

There are a few factors to consider when building a composite deck or wooden deck. Composite decks are made of wood fibers and plastics. They are easier to maintain than traditional decks but can be more expensive.

Traditional decks are made of natural wood, which can be stained or painted to protect them from the weather. The main disadvantage is that they may also fade in color over time. Traditional decks are susceptible to insect damage, but this can be prevented by using a sealant or coating.

In the end, the best type of deck for you depends on your budget and your lifestyle. If you are looking for a low-maintenance option, then composite decks may be the best choice. 

If you are willing to put in a little extra work to keep your deck looking beautiful, wood decks may be better. Whichever type of deck you choose, make sure to research the products thoroughly before buying them to know what you are getting into.
