Wood Decking and local data in Illinois
Wood decks in our covered Illinois ZIP codes see rain or snow on about 76 days a year, so ground-contact rated lumber for posts and low framing, and a penetrating finish renewed every few years, decide how long they last.
About 17 days a year at 90°F or hotter dry boards out quickly after rain; that cycling is what opens checks, so fasteners set flush and sealed end cuts matter.
With a median build year of 1975, wood remains the lowest upfront-cost choice for the many backyard decks here.
