Deck Repair and local data in Illinois
57% of homes in our covered Illinois ZIP codes — roughly 717,721 houses — were built between 1960 and 1999, the age group whose original or added-on decks generate most repair work. Another 27% predate 1960, where the ledger attachment deserves a close look.
Water starts most repairs: measurable rain or snow falls on about 76 days a year (about 39.7 inches in total), and rot begins where water sits — board butt joints, post bases and behind the ledger.
About 78 freeze-thaw days a year back screws out and open checks in unsealed boards, which is why loose fasteners and split boards top spring repair lists.

Who issues permits for deck repair in Illinois?
Illinois building codes for single-family homes are largely adopted and enforced at the municipal and county level, so requirements differ between suburbs. Contact your village or city building department. New decks, replacements and structural repairs usually need a permit; staining and like-for-like board swaps often do not.
Who licenses deck contractors in Illinois?
Illinois has no single statewide license for deck builders; licensing and permits are mostly municipal. The state's Home Repair and Remodeling Act does protect homeowners: on jobs over $1,000 the contractor must give you the 'Home Repair: Know Your Consumer Rights' pamphlet before you sign.
