When looking at building your deck this year, think natural materials. Recycled plastic and composite decking is not always the answer. Think about the polustion and factory emissions being put out into the air these days. Polustion starves the atmosphere from natural element trees need to live and give back. Pressure treat lumber might be okay to use but think about it for second. Pressure treated lumber is manufactured using chemicals that turn natural materials of spruce, pine or fir lumber green and or brown in colour.
