Many decks are made of pressure treated pine. Good quality treated pine will last thirty years or so before there is any substantial decay. However, discoloration and splintering can begin after only a few months. For this reason, most people take on a regular cycle of maintenance. Failure to do so won't cause your deck to rot, but your deck will most certainly become discolored and the surface will become rough and prone to splinters. Many people never treat and seal their decks. Untreated decks don't fall down or rot away quickly. Nothing dramatic happens. They will simply get dirty and the surface will become much rougher much sooner. Splinters are a common problem with wood decks. Another hazard is slick surfaces. Much of the dirt we see on a poorly maintained deck is actually living organisms. Just like the algae and moss that grow on rocks next to a stream, the organic material growing on a deck can make the deck very slippery when wet. Cleaning and sealing a deck kills, removes, and slows the return of organic build-up. Free Estimates: http://www.marylandpowerwash.com/QuoteForm.htm
