Pressure Treated Decks

These decks are constructed with lumber that has been impregnated with a variety of preservative chemicals to prevent rot and insect infestation in exterior applications. Many species of wood can be treated, Pressure treated lumber is ideal for outdoor construction as it has a long, useful life span and is much less expensive than alternatives. Treated wood can last more than 40 years in some cases. The downfall to using this product as a decking material is that the sun warps, twist, cracks and discolor the product very rapidly. This product also requires costly maintenance. We have discovered most decks using this product as top decking will have a lifespan of about 12-15 years before replacement is needed. The same product used as the deck frame yields far more life to the deck as it is not subject to the same direct sunlight or standing water conditions.
