● Low maintenance: Trex decking requires very little upkeep and maintenance, unlike a wood deck.

● Unique shapes: Trex has a unique design system that allows for curves and other shapes for unique deck designs.

● Less contraction and expansion: Unlike wood which contracts and expands from summer heat and winter cold, leading to damage, Trex boards do not experience as much contraction and expansion, reducing damage.

● Scratch resistance: All Trex products come with varying levels of scratch resistance which keeps your deck looking as good as new.

● No sealant: Trex decking does not require regular sealing, unlike wood decking.

● Easy to install: Trex boards weigh upto 60% less then real wood deck boards, so they are much easier to work with when building a deck.


● Weight: Trex decking weighs 50% – 70% more than natural wood decking, which will increase the cost of transporting the decking.

● Replacement: If damage occurs to your Trex deck, it will require full replacement of the damaged boards, unlike wood which can often be sanded down or restrained to fix the damage.

● Cleaning: To prevent mold and mildew growth, a Trex deck should be cleaned semi-regularly with warm soapy water.

Warranty of a Trex Deck

A Trex deck comes with a twenty-five year limited warranty. High performance Trex decking products, such as Trex Transcend decking, also comes with a limited twenty-five year stain and fade warranty.

Trex Decking vs. Wood Decking Cost

When choosing your decking, you are likely considering whether to install a wooden deck or a composite deck. Both options have their benefits and drawbacks.

Trex Decking can be slightly more pricey than wood decking, depending on the features you choose. A Trex deck costs on average $5 to $12 per square foot, compared to wood decking which costs $3 to $7 per square foot. Pressure treated wood will be more expensive, costing between $6 and $14 per square foot.

While the initial cost of a Trex deck is higher, the maintenance cost will actually balance out that price difference. Maintaining a wooden deck can cost about $500 per year, whereas a Trex deck costs almost nothing to maintain.

Moreover, Trex decking, unlike wood decking, does not require any sealant, which will save you hundreds of dollars.

Also, a Trex deck has a longer lifespan than a wood deck, so you will get more for your money. The lifespan of a Trex deck can be over twenty five years, whereas a wooden deck can last as low as five years or up to twenty years.

Trex vs. TimberTech Composite Decking

Among all the composite deck manufacturers, TimberTech is Trex’s top competitor. They are in the same price range, although Timbertech is a bit more expensive.
Thus, homeowners looking into installing a composite deck, often compare Timbertech vs Trex decking.

Overall, both companies are very similar. Both TimberTech and Trex use recycled plastic and sawdust for their boards, require very little maintenance, and do not experience scratching, staining, or warping.

The main difference between these composite decking products is that TimberTech surrounds their boards with a plastic coating, whereas Trex only covers the top of their boards with plastic coating.

Both approaches have advantages and disadvantages, such as increased ventilation for Trex and increased protection for TimberTech.

Trex decking outshines TimberTech when it comes to scratch resistance. Trex Transcend is known as one of the most scratch-resistant composite decking materials on the market, making it an excellent choice if scratches are a concern.

In terms of materials prices, Trex is actually about 40% cheaper for each of its series, compared to the same class series that Timertech offers. However, once you add wood railings and substrate to a Trex deck, the total cost between the two brands becomes very similar.

In terms of looks, Trex is known for providing a more realistic wood appearance compared to Timbertech, which has a much more plastic look and feel.

TimberTech has a longer warranty of thirty years, compared to Trex’s twenty five year warranty.

Overall, if you are choosing between both company’s mid-range products, you can’t go wrong with either. If you are looking for a high-end product, Trex’s Transcend is favored.

How to Maintain Your Trex Deck

Trex decking is notoriously easy to maintain. A regular sweep will remove debris from the surface of the deck, and hosing down the deck will remove smaller particles and dirt.

You can also scrub the deck with some hot soapy water and a soft bristle brush for a more thorough clean, or use a pressure washer with a PSI lower than 3,100 to get your deck looking as good as new.

If you experience staining on your Trex deck from the hard water of your hose, simply clean it with white wine vinegar, and rinse, or purchase a cleaning solution designed for removing hard water buildup.

If pollen or dirt remains on the decking for a long period of time, you may experience some mold or mildew. To clean it, simply spray the deck with a hose and scrub it down using a soft bristle brush and water.

To avoid voiding your stain and scratch warranty, be sure to use a cloth or a soft bristle brush when cleaning. Also, you must clean up food spills up to seven days after they occur to be eligible under the stain warranty.

Trex.com offers a wealth of resources of building your own Trex deck without hiring a pro. Building a deck on your own can save you thousands of dollars, since the cost of professional deck construction is 60-70% of the total decking cost.

Can You Install Trex Over an Existing Deck?

Many homeowners looking to save money on installing a new deck wonder if its possible to put Trex boards over the existing deck. The good news is that YES this is not only possible but can actually be a great way to resurface your old deck without spending a fortune.

Overtime, real wood deck boards age and create many problems, such as warping, nailing sticking out, cracking, high risk of getting splinters, etc. They are easily replaced with long last Trex Boards at a fraction of the cost of building a new deck.

If the foundation and the framing system of your current deck is sound and its just the walking boards that are looking worn, you can simple replace them with new and beautiful Trex boards and deck railings.

Overall, if you are replacing the walking boards yourself, you can easily end up spending less then $1,000 on new Trex boards and railing, if you are going for either Trex Select or Trex Enhance.

Customer Reviews

Trex decking is favored by customers for its durability and long lifespan. Users appreciate the low level of maintenance and resistance to scratching and staining. Customers also appreciate the lack of splinters, especially for homes with children.

The largest complaint about Trex decking is that it can warp. While Trex decking supposedly is warp-resistant, still many users claim that their Trex deck boards warped at the edges. Also, several customers say that they have had issues with Trex screws falling out.

Others say that their Trex decking faded over time, or experienced mold and moisture damage. Unlike wood which can be treated for stains, scratches, or fading, the marks are very difficult to remove from Trex decking and remain until the deck can be replaced.

Many of the issues that customers complain about may be related to installation, while others may be related to the quality of the product. Trex Enhance, for instance, is much more likely to experience issues with scratches than Trex Transcend.

On the whole, though, Trex is a reliable product that most customers are extremely satisfied with.

How Much Value Does a Trex Deck Add to a House?

Trex Decking Prices

Installing a new deck is an expensive remodeling project, so its a good idea to get sense of the return on investment you can expect. In general, the ROI of a new deck that is made of a composite, such as Trex Decking is about 68-71%. This is the same return on investment as building a small one addition.

This means that if you spend $10,000 on your Trex Deck, you can expect to get back $6,800-7,100 when you sell your home.

In general, decking is not a top recommended project to add just for the purpose of boosting resale value. Its especially not worth it to invest thousands of dollars into a very fancy deck with all the bells and whistles if you plan on moving out in the next 3-5 years.

Its best to build a deck that you can actually enjoy and one that will enhance your quality of life while you are living in your home. Having a decent ROI is a nice added bonus.
