Does composite decking need maintenance?
It's true that many composite decking options require very little maintenance but they do need basic cleaning in order to keep them looking presentable No, you don't need to repaint or reseal composite decking, and it is very resistant to rot, however, it's a good idea to sweep them clean weekly in order to prevent the growth of mold and lichen.
Is composite decking slippery when wet?
Composite decks are not slippery even when there is water on the surface. The problem, however, is when there is an accumulation of both ice and water on your composite decking. Aside from being the cause of accidents, ice, and the removal of it, can cause some damage to your patio. Non-anti slippery composite decking.
Is composite wood waterproof?
Composite decking does not absorb water. When moisture gets trapped under the decking and on top of the wood joists, it stays there and keeps it from drying properly. Homeowners who are looking for waterproof composite decking materials should look for those that have special features.
Why is composite wood so expensive?
Most composite decks are manufactured from the by-products of wood such as wood chips, sawdust, and recycled plastic materials.
This unique combination makes composite decks expensive than other types of decking material.
How much does composite wood cost?
Averaging between $3.50 and $6.00 per linear foot, the cost of installing a high-quality composite deck will certainly be higher than building with traditional pressure treated lumber, which can cost between $5.00 - $7.00 per (8') board.
What are the disadvantages of composite decking?
A pricey alternative to wood. Durability comes at a cost, as composite decking is more expensive than wood.
Composites aren't natural.
Composite decks aren't completely maintenance free.
You'll need to comparison shop.
Cons of Composite Decking
What are the problems with composite decking?
One of the most common complaints about composite decking is mold. Decking that is in shaded area or areas that tend to get wet frequently have been shown to grow mold and stain the deck. This is not restricted to composite decking. Wood decking can grow mold, mildew and algae.
How long do Composite decks last?
Composite decking can last over 20 years with the proper care and maintenance. Composite holds up better under hot or cold weather shifts. Composite is resistant to rot, mold, and termites, which can take their toll on wood decking materials. Composite does not require as much upkeep as wood.

Even the best of materials has its disadvantages. The same goes for composite decking materials. Composite materials are some of the best boards to use in decking. It’s durable, low-maintenance, and long-lasting. However, it too has some cons. When building a deck, you will want to weigh these pros and cons. But what are the disadvantages of using composite decking boards?

Disadvantages of Composite Decking Boards

High Initial Cost 

The first disadvantages of composite decking boards are their price, and the price is one of the major deciding factors when we are buying anything. So how much do composites cost compared to traditional decking materials? Wood, especially softwood, can cost as much as half of the price of composites. Some hardwoods are more expensive than composites, but there are only a few. 

So when the budget is concerned, you may prefer wood to composites. With that said, there are still plenty of excellent trade-offs for the higher cost of composites. Composites are long-lasting and can last for at least twice that of softwood decks. A softwood deck can last for 15 years max, while a composite decking board can last for more than 25 years.

 They are also easy to clean. You will only need to use common household cleaning items, such as a brush and some soapy water. They are also resistant to many issues found among wooden patios. For instance, they are resistant to insect damage, don’t splinter, and rarely warps due to shrinkage and expansion. 


Another disadvantage of working with composites is their heavyweight. This problem will be an issue if you’re installing your deck all by yourself. It also makes it hard to transport these materials. Because of their heavier weight, you will need to make a sturdier frame that can support the boards.

 Fortunately, some boards are designed to be lighter than the regular composite decking boards, called hollow composites. The inner portion of these boards is hollowed-out, making it easier to transport or install. Despite their hollowed centres, they are as strong as regular composite decking boards. However, depending on where you live, it may be hard to obtain these boards.

Can’t Be Painted 

You may have heard that you can’t paint a composite board. The truth is, you can paint the board, but it is not recommended. Because of the smooth outer plastic layer of most composites, the paint will only slide off the boards. To paint it, you will need to sand them. But by doing so, you will be removing any added protection that the composites provide. For instance, it will lose its moisture-resistance and will be more prone to splinters and peeling. 

So, if you plan to change the colour of your deck every few years, composites may not be for you. But if not, then composites can be excellent materials. They don’t fade like wood. Wood turns into grey when it fades but composites only lighten in colour. And the best thing is, you can select different patterns, colours, or grains when buying composite decking boards and tiles. So when buying composites, make sure that you have the right colour and pattern. 

Can Be Slippery

 Another minor issue with composite decking is that it can be slippery when wet. Because most composites have smooth plastic caps, it gets a little slippery. But they are less slippery than 100% plastic boards. Like wood, composites can also be slippery if moulds grow on the surface. However, the chances of these moulds growing on composites are lesser than on wood. As long as you clean it regularly, you won’t have to worry about this issue.

 So if you are planning to build a deck near a water feature, such as a fountain or pool, you may want to go with hardwoods. However, if you do want to get composites, you can find some which are less slippery than others. Go for composite decking boards with grained textures. This feature increases friction and makes it safer near water. And the best thing is, composites are resistant to water.

Overall, composite materials are excellent decking boards. However, they do have some disadvantages, and there may be times that you would want to use hardwoods instead.
