What Are the Pros and Cons of PVC Decking?

Shopping for deck materials isn’t quite like shopping for a new outfit; it’s a significant investment and long-term commitment, so it requires research, comparisons, and, for the truly indecisive, lots of samples. As you shop for decking options, you‘ll need to weigh the top considerations for every material before making an informed decision. Here, we break down a popular option: PVC decking.

Follow along to discover the truth about PVC decking, its advantages and disadvantages, and why its benefits might outweigh its cons, depending on your needs.

What are the downsides of PVC decking?

Like most things, PVC decking has its pros and cons. Some of its downsides include:

• Higher price tag - The core disadvantage of PVC decking is that it is often priced at a premium compared to other deck boards. Although its long-term value may justify this price tag for some buyers, the added cost reduces its accessibility for budget-conscious builders. 
• Less eco-friendly composition - Unlike wood or composite options, PVC decking typically isn't made from natural or recycled materials. The use of plastic and its lack of biodegradability may be a concern for builders on the hunt for an environmentally friendly material. 
• Potential fading or discoloration - Especially in areas of high UV exposure, PVC decking may fade over time. In some instances, PVC decking can also discolor when used with rubber accessories, like a welcome mat.

These issues might be enough to deter some homeowners from building with PVC, but every decking option has its disadvantages. Despite its cons, PVC remains one of the most effective deck board options for climate-resilient outdoor spaces. This high-quality material offers long-term value and durability.

What are the upsides of PVC decking?

Despite its downsides, PVC decking does offer many benefits that some lower-budget options may not. In particular, some PVC decking options are fire resistant, setting them apart as a top option for those building in fire-prone areas.

PVC decking is an excellent option for homeowners who are looking to maximize their return on investment. Don't believe us? Check out these top benefits and decide for yourself.

Fire Resistance: Where PVC Decking Shines

One of the core benefits of PVC decking is that it can be fire resistant. For homeowners living in fire-prone areas, PVC decking lines like Trex® Refuge™ can slow fire spread without sacrificing aesthetics*. It complies with International Wildland-Urban Interface Code (IWUIC) ignition-resistance requirements, is WUI-compliant for Wildland/Urban Interface zones and is Class A Flame Spread Rated.

And unlike other industrial fire-resistant materials like aluminum, PVC decking can mimic a natural wood look while outperforming traditional wood** decking in flame spread tests.

Extended Lifespan

PVC decking is built to last, far outpacing lower-priced options like wood decking. With PVC’s longevity, you’re less likely to need to replace boards over time, ultimately cutting down the overall cost of your deck. What’s more, PVC deck boards like Trex® Refuge™ are backed by a 50-year limited residential warranty that reduces the risk of costly updates later on — and gives you peace of mind.

Minimal Maintenance

Traditional decking options like wood require painting, staining, sanding, cleaning and more to keep them looking fresh. On the other hand, high-quality PVC deck boards require little to no maintenance to stay in pristine condition, meaning fewer maintenance costs and less hassle.

Maximum Durability

Thanks to its highly durable plastic polymer material, PVC decking is resistant to damage. Plus, without the risk of splinters or snags, you can enjoy your deck as you like, whether that’s for a sunrise yoga session or playing hide and seek with your kids. You can even let your pets join you on your deck without worrying about claw marks.

And since PVC is an inorganic material, it also stands up to the elements. It’s resistant to moisture and bugs, preventing deterioration from threats like mold and pests.

Luxury Aesthetic

For homeowners who want a classic wood-grain look, PVC decking offers the aesthetic you want without the headaches that come with natural wood boards. No rotting, warping, or unsightly knots when you build with PVC. It comes in a range of colors and styles, some even in wood-like finishes.

Wide Range of Pricing Options

Some PVC decking may indeed be more expensive than budget-conscious materials like pressure-treated wood, but just like any decking material, it comes in a range of options. What's more, the cost of a deck goes beyond simply the cost of its deck boards; you must also consider the long-term costs of ongoing maintenance, repair and your material's durability. Some high-quality PVC deck boards like Trex® Refuge™ even offer exclusive benefits like fire resistance, enhancing their overall value.
