Decks in Texas endure extreme thermal shocks: afternoon temperatures exceeding 105°F followed by sudden drenching thunderstorms. Selecting the right decking material prevents splintering, warping, and perpetual maintenance.

Framing Substructure Best Practice
Even when using composite surface boards, deck framing joists are typically pressure-treated pine. In Texas, always apply butyl joist tape (Trex Protect or Vycor) along the top of all framing joists and ledger boards to prevent trapped moisture rot under the composite clips.
