As a homeowner, you probably want to make the most of your open space and enjoy the weather that other places envy so much. Chances are, your home already has a wood deck or you’re thinking about installing one. Not only does a deck allow you to enjoy the mild weather, it also expands your living space and increases the value of the home.
However, many homeowners wonder how long does a wood deck last? Typically you can expect a deck to last between 10 and 30 years if it’s made of untreated wood and 50 years or more if it’s made of treated or composite wood. However, the lifespan of a deck also depends on its materials and how you maintain and seal it over the years.
Factors That Affect the Lifespan of Your Deck
Several factors can significantly influence the lifespan of your wood deck:
1. Maintenance: Regular cleaning, sealing, and reconditioning can dramatically increase the longevity of your deck. It’s important to sweep away debris, remove mold and mildew, and apply a protective sealant to protect it from the elements.
2. Climate and Weather: The climate and weather patterns of your location can interfere with the lifespan of your deck. Decks in areas with extreme weather conditions, such as heavy snow or intense sun, can wear out faster than those in temperate areas.
3. Use and Foot Traffic: The amount of use and foot traffic your deck receives can also affect its lifespan. A deck that gets a lot of use may show signs of wear more quickly.
4. Quality of Materials: The quality of the wood and other materials used in the construction of your deck directly interferes with its durability. High-quality materials are more likely to stand the test of time.
5. Quality of Construction: The way your deck is built, including the quality of construction and the skill of the builder, can have a significant impact on how long your deck will last.
Treated Wood vs. Untreated Wood
When choosing materials for your wood, it is important to understand the difference between treated and untreated wood.
Treated wood is more durable than untreated wood. Treated wood is pressure treated with a chemical preservative that helps protect it against rot, decay, and insect damage. Pressure treatment causes the chemicals to penetrate deep into the wood fibers, making it much more resistant to mold and decay than untreated wood.
Treated wood is recommended if your deck will be exposed to moisture or outdoor elements, as it is much more resistant to rot and water damage.
