A lot people worry about the appropriate decking material to choose when getting a new deck. Two of the most common decking materials are pressure treated wood and vinyl. While wood remains the most popular choice for decking, vinyl decking is proving to be a breakthrough material for constructing decks. In this blog, we will explore the benefits and disadvantages of both decking materials so that you can choose the best one for your deck.

Pressure Treated Decking

In pressure treated wood, the decking wood is pretreated by immersing lumber in chemical preservatives. The tank in which the wood is placed is first depressurized in order to isolate air. Then, at high pressure, preservative fills up the tank. The pressure allows the preservative to penetrate deep into the lumber.

Because of this treatment, the lumber becomes unappetizing for pests and bugs that love to feast upon untreated wood. Decay caused by fungus and mold is also prevented. Pressure treated wood has an additional lifespan of 20 years or so even in harsh climate conditions.

Previously, a carcinogenic chemical called copper arsenate was used to treat the wood. However, nowadays, less harmful materials like copper azole, non-metallic and carbon based preservatives are used. However, every year, the pressure treated preservatives leach to the surface which would require you to apply a coating in order to lessen the amount that leaches the top surface of the deck. This will also provide protection against the sun.

The widespread availability of pressure treated lumber and its affordability makes this material very popular. Yet, there are some disadvantages to pressure treated wood as well. The primary one is warping. Pressure treated decking swells and cracks. The decks made up from pressure treated wood require routine maintenance. Apart from the application of preservative coating, they also require a power washing annually. Here is an overview of the pros and cons of pressure treated wood.


  • Material and labor cost is extremely low
  • Can be used for decks directly in contact with the ground
  • Extended life if maintained properly


  • Scratches, stains, warps and cracks
  • Maintenance is high

Vinyl Decking

It is one of the most innovative materials that can be used in exterior flooring for decks. Vinyl is a durable material and has really low maintenance costs. Since vinyl does not crack or warp, it does not really need a sealant to be applied regularly.

Vinyl deck can also be given a similar texture as that of wood. It’s available in a multitude of other different styles like granite and may even have a mottled appearance. You may create unique designs with the help of vinyl to increase the aesthetic appeal of your deck. Following is an overview of the pros and cons of vinyl decking.


  • Requires very little maintenance with long term warranty
  • Does not fade with time nor does it splinter
  • Resistant to scratches, stains, warping and cracking
  • Not susceptible to insects, mold and fungal growth


  • More expensive than pressure treated wood
  • The selection of colors is limited
