Below-grade spaces get wet from four directions: through the floor when the water table rises, through walls where grading pushes rain toward the foundation, down window wells, and from a sump pump that fails at the exact moment it matters. Each source has a different fix, which is why 'my basement is damp' needs a look, not a guess.
In Georgetown, the basement moisture guide questions are read against a local fact first: Georgetown sits in Williamson County where the North and South Forks of the San Gabriel River meet, with Blue Hole, the swimming hole on the South Fork, as its emblem of the river that organizes the town. That fact is what changes the order of the steps below for a Georgetown household: what gets documented first, what can wait a day, and which call is the first call. The sequence itself is the standing one for this work; the local detail is what makes it this city's version of it.
Warning signs in order of seriousness: a musty smell that never leaves, efflorescence (white mineral lines) on foundation walls, rust at the base of the furnace or water heater, and stored cardboard going soft. Standing water is the last sign, not the first.
A battery backup for the sump pump and a high-water alarm are the two cheapest upgrades in this whole guide. Pumps fail during storms because storms are when power fails - plan for the coincidence.
