Wooden decks and patios need to be re-stained every few years. The coating seals against rot and the elements. Without regular reapplication, the old stain will start to wear away. This leaves the wood vulnerable to mold and parasites, insects, and even warping from UV radiation.
A professional stain will do more than stop moisture from getting into your wood. It keeps the color bright and fresh even in direct sunlight. It also prevents cracks and splinters, so you don't have to worry about walking on the deck with bare feet.
If it's been a couple years since your deck was last stained, find a local deck staining service. Professionals do more than just paint over the old coating. They will remove traces of the previous stain and clean the wood. Then they will apply long-lasting stain and a top coat of sealant for extra protection.
