Choosing materials. Are you the type of person who has to have a natural decking material? If so, your options go beyond pressure-treated lumber or cedar. Ipe, cumara, garapa, cambara and bamboo are among the many harvested woods that you can choose from. Try ipe, a sustainable product, if you like the darker, richer look of mahogany. Or use bamboo if you're looking for something that's lighter and also known for its sustainability. Do you have concerns about maintaining the deck over the long term, but want the look and feel of wood? If so, maybe a synthetic material like a wood-plastic composite (WPC) is right for you. When selecting a decking material, Jeswald suggests considering:accoya (radiata pine) for its resistance to rot and insects as well as sustainabilitypressure-treated woods for their long life and low costcedar (white and red), a native materialWPC for its woodlike appearance and low maintenancePVC for its resistance to weather, insects, splintering and fadingcoated WPC for combining the best features of WPC and PVCAnd did you know that there's also aluminum, vinyl and fiberglass decking? These aren't all that common, but they may be just the solution you're looking for.Take field trips to look at decks made of the materials you're considering. And talk to a local decking pro to get some advice on what's available in your market, plus each material's cost and maintenance.
