For vinyl window replacement vs wood windows in South Louisiana humidity, quality vinyl resists swelling and rot, but well-built, factory-finished wood can work with vigilant upkeep.

Set, square, and shim without distorting the frame Bed the nailing flange or frame perimeter in fresh sealant per instructions, not dotted caulk that leaves voids. Place shims at the jambs behind the hinges and strikes to maintain reveal and latch alignment. Operate the window before final fastening; if it sticks now, it will leak later.
