How Are Composite & Wood Decking Different?

While it may be easy to assume all decking is the same, there are several key structural differences between composite decking and wooden decking.


Wood Decking

Traditional wood decking is as basic as it sounds - decking made from wood!

It is usually treated and stained to help preserve the lumber and resist the weather.  As it ages, it requires more maintenance to keep it from splintering and warping.


Composite Decking

Composite decking - technically called ‘capped composite decking’ - is a precise blend of wood and plastic polymers.  This polymer core is then wrapped in vinyl sheathing to provide protection and long-term durability.

It provides customization when it comes to the color, style, and texture of the decking materials.

What Are The Benefits Of Wood Decking?

Wood decking has three main benefits:


First, it is cost-effective

Here at Keystone Custom Decks, we estimate they are approximately $5,000 cheaper than a composite deck of comparable size.


Second, it is real wood

No matter the color or stain applied, it always has the texture and aesthetics of solid lumber!


Third, it is easier to replace individual boards

Most composite decking uses a snap-lock system.  Snap-lock systems are relatively easy to install, but they are harder to replace a single board if required.

Because wooden decking is screwed to the deck frame, it is easier to remove and replace individual deck boards.

Note:  Many would argue this third point is not as advantageous as it first sounds.  While composite decking rarely needs to be replaced, wood boards need to be replaced periodically due to splintering, warping, or rotting.  Keep reading to see the long-term benefits of composite decking...

What Are The Benefits Of Composite Decking?

While it costs more than wood decking, capped composite decking has multiple benefits:


First, it is highly customizable

Composite decking comes in a wide variety of colors, textures, and styles. In fact, certain styles look almost identical to wood decking!


Second, composite decks do not fade over time

Unlike wooden decks, you don’t need to worry about staining or repainting your deck.  When it comes to long-term aesthetics, this material won’t let you down!


Third, it doesn’t warp or splinter

This keeps the deck looking nice for many years, and it makes it safe for children, pets, and others. 


Fourth, it cleans easily and doesn’t stain or grow mold

Because it is wrapped in the vinyl sheathing, composite decking is easily cleaned with soap and water, and it won’t grow mold or mildew.  This removes the threat of staining and makes cleaning and maintenance easy.  

There are many more benefits to using composite materials for your deck.  Continue reading to discover these other advantages.

Which Decking Is Cheaper?

When comparing decking, pricing is one of the few areas where wood decking has an advantage.

As mentioned previously, we estimate the average wooden deck costs $5,000 less than using composite decking.

While this is not an insignificant number, there is a catch to the more cost-effective wood:  It requires more long-term care, maintenance, and replacement.  

Before choosing to go with lumber just because the initial cost is cheaper, be prepared to put in the additional maintenance and work on your deck.  

You should also be prepared to replace your deck sooner when using wood decking, and this fact alone often makes the initial savings not worth it in the long term.

It is important to note that manufacturers are aware of the price difference in materials, and they are working on materials and processes to make composite decking more price competitive.

What is an example of better pricing?

TimberTech has started producing a material called TimberTech Edge Premier Collection.  This material is cheaper than standard composite materials and closer to the cost of a wood deck.

While the Edge Premier Collection comes with the same long-term durability and low maintenance of capped composite decking, it is limited in the available colors and textures.

Which Is Easier To Clean?

When it comes to cleaning your deck, wooden decking has a significant fault:  it quickly gets stains, mold, and mildew, all of which can cause permanent blemishes.

These issues mean wood decks need to be cleaned regularly, because they leave permanent stains and potential damage if not quickly removed.

Cleaning a wooden deck properly requires power washing or hard scrubbing with a powerful cleaning agent.  If the stain or mold is a big enough issue, it can even mean needing to resurface or paint the deck.

Composite decking, on the other hand, is designed to repel liquids, mold, and other materials that leave stains.  Also, if something spills on the deck, it can usually be wiped up quickly.

However, if you want to clean a composite deck thoroughly, follow these six simple steps called the “soap-and-water method”:

  1. Remove all furniture from the area to be cleaned.
  2. Sweep the floor with a broom to remove loose debris and leaves.
  3. Rinse the floor with warm water.
  4. Prepare a solution of warm water and standard dish soap (we recommend Dawn).  The soap-water mixture should be similar to what you use to wash dishes.
  5. Using a nylon broom or brush of medium stiffness, put the brush head into the soap-water solution and scrub your deck.
  6. When you are finished scrubbing with the soap-water solution, simply rinse away the remainder of the dirt and soap.


Cleaning a composite deck is really this simple - no pressure washer or powerful cleaning agent required!

Which Decking Requires Less Maintenance?

We have already discussed the fact that wood decking is easier to replace or repair if only one or two boards need to be replaced.

At first glance, this may make it appear that wood decking is easier to maintain, but this is not true.

In fact, with composite decking, you don’t need to worry about replacing any deck boards!

Why is this material so worry-free?

Because it requires almost no maintenance!

The engineering and vinyl wrap of capped composite decking means the boards don’t crack, split, warp, splinter, or experience other negatives common to wood decking.

Other than the occasional washing or cleaning with the soap-and-water method, you won’t need to worry about your composite deck.

Wooden decking is the opposite - it does require regular care.  This includes restaining or painting the deck periodically, replacing broken or splintering boards, and needing to remove mold or mildew from the deck over time.

Mold and mildew can cause severe damage to a wooden deck.  If it isn’t removed quickly, it can penetrate the lumber, begin to spread, and destroy the deck in a matter of months.

Which Deck Material Is More Durable?

Similar to the maintenance question, composite decking shines in long-term durability.

Because of the core being wrapped in vinyl, composite decking is engineered to last a minimum of 25 to 30 years.  In fact, some manufacturers, like Trex, are so sure about their materials lasting 25 years that they back their products with a 25-year limited warranty!

What other factors make composite decking durable long-term?

  • It resists hot and cold temperatures and does not swell or contract.
  • Wood decking invariably begins to warp, twist, and splinter over time.  Composite decking is designed to hold its colors and shape for decades.
  • It does not fade or require regular staining or painting.  
  • Unless they are abused or mistreated, composite materials do not scratch over time.


Wooden decks long-term durability depends on water-proof sealant or stain being regularly applied, often every several years.  Keeping the deck mold and mildew-free is also critical to extending the life of wood decking.

At Keystone Custom Decks, we have seen composite decking live up to its hype.  

We have been installing composite decking for over thirty years now, and there is no question in our minds - they live up to their expectations of long-term durability!  

5 things that make composite decking durable
Which One Is More Customizable?

Both wood and composite decks can be customized in color, but the amount of work required is vastly different between the two.

Wood decking means the deck has to be painted or stained to get the desired color, and periodically you will need to deep-clean and repaint or restain the deck due to fading.

In contrast, composite decking is a “set it and forget it” approach to design and color.  

Once you choose the color and decking style you want, you are finished - no painting or repainting necessary!

Composite decking also allows for more textures and styles in truly customizing your deck.  Whether it’s a modern, rustic, traditional, or earthy feel you want, you’ll find a style to match.

In fact, several styles look almost identical to lumber if you want the wood aesthetic without the related maintenance and issues!
