Deck builders in Tennessee

12% of homes in the covered area predate 1960, 19% were built in the 1960s and 1970s, 28% in the 1980s and 1990s, and 41% since 2000. The oldest housing is in Madison (1977), Nashville (1980) and Old Hickory (1983); the newest is in Nolensville (2012), Spring Hill (2010) and Thompsons Station (2006). That spread is why deck projects here range from rebuilding retrofit decks on early-20th-century homes to upgrading decks on houses built in the last decade.

• Replacement and major repair: about 252,371 homes (39%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
• Upgrades and expansions: about 152,079 homes (24%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.
• Retrofit decks on older homes: about 126,134 homes (20%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.

Average annual snowfall ranges from about 1.2 inches (Goodlettsville) to 5.8 inches (Greenbrier). Days with at least 0.1 inch of precipitation range from about 79 (Goodlettsville) to 87 (Murfreesboro). Those differences change footing depth requirements, how often wood needs sealing and how much snow and moisture a deck must shrug off — so the right design for one Tennessee community is not automatically right for another.

Composite and PVC resist humidity; lighter colors help in full sun. Treated pine remains common. Individual community pages explain how local housing age and the nearest weather station's data change that recommendation.
