Sunlight and UV Rays

Cost differences vary depending on the region, but composite decking may be as much as 60 to 70 percent more expensive than conventional decking.


Composite decking is much heavier than pressure-treated wood, making it harder to handle.


Many people feel composite decking looks unnatural and less appealing than conventional wood decking.


The material is comparatively soft and scratches and gouges easily. It can be marred by animal claws, foot traffic and scraping from chairs.

Long-Term Wear

Unlike wood decks, which can be sanded and repainted or re-stained, composite decking will start to show signs of wear after five years and will need to be replaced rather than renewed.


Even after staining and sealing composite decking, the material will still absorb liquids. Juice, wine, sodas and other colored liquids may cause stains that cannot be sanded out or removed.
