The lifespan of treated decking depends on several factors, including the type of treatment, the wood species, the environmental conditions, and how well it’s maintained. Here’s a general breakdown:
- Pressure-Treated Wood Decking:
- Pressure-treated wood is commonly used for decking and can last between 15 to 25 years. The treatment process helps protect against rot and insects, but the actual lifespan will depend on factors such as the quality of the treatment, exposure to elements, and regular maintenance. In harsher climates or with minimal upkeep, the lifespan may be shorter.
- Composite Decking:
- Composite decking, made from a blend of wood fibers and plastic, typically lasts 25 to 30 years or more. It’s highly resistant to rot, insects, and UV damage, and requires less maintenance compared to traditional wood decking.
- PVC Decking:
- Similar to composite, PVC decking is made entirely from plastic and can last 30 years or more. It’s very durable and resistant to moisture, insects, and fading.
- Hardwoods:
- Tropical hardwoods like ipe, mahogany, and teak are known for their durability and can last 25 to 50 years or more if properly maintained. They’re naturally resistant to decay and insects, but they also benefit from periodic maintenance.
- Cedar and Redwood Decking:
- These woods are naturally resistant to decay and can last around 15 to 20 years. Regular sealing and maintenance can help extend their lifespan.
