Trex decks
Pressure treated pine is a good all-around material. It is inexpensive, readily available, very durable and will last a very long time if properly maintained.
There are many types of composite decking, good, bad, cheap and expensive. We install "the world's best high-performance composite decking," Trex Decking products. Trex is a top-of-the-line product with warranties ranging from 15-25 years.
Cedar is a good material for pergolas and pavilions but does not fare as well on ground level decks as pine and composite materials due to its dry nature.
Tongue and groove white pine is a good option for ceilings, especially on pavilions.
