The life expectancy of deck boards varies widely based on the material, climate, and maintenance. Untreated wood boards typically last 10 to 30 years with proper care, while pressure-treated boards can last up to 50 years. Hardwoods generally outlast softwoods. Composite boards also tend to last longer than natural wood. Environmental factors like arid or humid climates can shorten a deck's lifespan. To extend the life of wood decking, it's important to consistently clean and seal it to protect against moisture, UV light, and insects.

No. In most cases, it’s not colder or freezing temperatures that affect decking materials but the amount of moisture that seeps into the materials as a result. For example, wood decking material is more likely to suffer from rot or decay when exposed to excess moisture from snow or ice. An extreme change in temperature can cause wood to expand or contract, but only if it’s not properly treated beforehand.

PVC decking can get slippery when wet because it’s made from plastic. However, composite and wood decking can also be slippery when wet. It’s best to wear shoes with grippy soles when walking on a wet deck, no matter the material, and to be extra cautious not to slip and fall down.

Whether composite decking is better than wood depends on your priorities, especially regarding budget and maintenance. Composite decking offers superior longevity (30 to 50 years) and durability, and it is low-maintenance, requiring no sanding, staining, or sealing. In contrast, wood decks typically last 10 to 30 years and need refinishing every few years. While the upfront cost of composite is higher than wood, the reduced maintenance can lead to long-term savings. If a lower initial cost is the primary factor, wood is the more affordable choice.
