What standing water indoors means in Lake San Marcos
In Lake San Marcos, standing water indoors is a moisture problem first and a cosmetic issue second. Lake San Marcos water damage is shaped by the community structure: a private gated lake-and-golf community within greater San Marcos, built primarily in the 1970s and 1980s on slab-on-grade construction with copper supply lines under slab. That local housing mix shapes where we look first when this symptom shows up.
