Treated wood and composite decks can last up to 50 years. The price is “always a tough question,” says Josh Goldstein, president of 1918 Preservation in Perry, Ohio. Many will live for more than 10-15 years. It’s the perfect material for fences and decks because it retains less moisture than many other woods commonly used for decks.
Wood decks can last up to 15 years if properly maintained, making them a solid option but by far the least durable option for the decking material.
How often should you replace your deck?
If caught early, it may be possible to repair the damage without having to replace the entire deck. If you’re interested in composite decking due to their easy maintenance and durability, you’ll be happy to know that there are a few ways to replace your timber decking with composite decking. However, if your deck shows signs of age and is over 20 years old, you may want to consider a deck change. The International Association of Certified Home Inspectors estimates that decks made from timber boards will last around 15 years, while lumber gives you 10 to 30 years.
Because these posts are the foundation and structure for your deck, you’ll need them in shape before you can host summer deck parties.
How long should a pressure-treated wooden deck last?
One thing you might not know about pressure-treated wood is that it usually comes damp or wet from the manufacturer. In particular, TimberTech polymer and capped composite decks were developed using an innovative technology that enables a highly durable and long-lasting decking board. It stores more carbon than it produces, while pressure-treated wood is quite harmful due to the chemicals used during the pressure treatment process. Pressure-treated wood also needs to be cleaned regularly. If you want a stained look, the stains must be reapplied as the sun bleaches the wood over time.
