Composite Wood Basics
If you're ready to replace your current decking, there's a good alternative to consider — composite wood, which is actually part wood and part plastic.
Composite wood is a bit more expensive than pressure-treated pine, but in the long run — because it doesn't have to be resealed or painted — the composite wood will actually be less expensive.
And just because it's a composite doesn't mean it won't work just like wood. It will. You can drill holes into it, cut it, drive screws into it and drive nails into it.
Don't just think decking when you consider composite wood. It's become popular for exterior trim because it can be purchased in lengths up to 16-feet long, and it doesn't warp, split or knot.
