San Marcos sits south of Austin along the I-35 corridor, split by the San Marcos River and anchored by Texas State University. We run crews down here regularly because the mix of aging rental housing near campus, riverfront homes along Sewell Park and Rio Vista, and newer subdivisions off Hunter Road all see water damage for different reasons — old galvanized plumbing in one, flash flooding from the river in another.
This is Hays County, not Travis, but it's squarely inside our service area and we treat it that way — same 24/7 response, same equipment, no extra markup for being 'out of town.' The San Marcos River itself is the wildcard here: after heavy rain it can rise fast, and low-lying streets near the square and near Sewell Park have flooded homes and crawlspaces that looked fine the day before.
Housing stock varies a lot block to block — pier-and-beam bungalows near downtown that are decades old, slab-built ranch homes from the 70s and 80s further out, and a wave of student-rental duplexes near campus that get neglected maintenance and burst supply lines more than most. We adjust our drying and extraction approach based on which of these we're walking into, because a wet crawlspace under an old pier-and-beam house dries completely differently than a slab-on-grade duplex.

Water Damage Repair in San Marcos — Local Notes
- •Pier-and-beam homes near downtown and Belvin Street often trap moisture under the house for weeks after a leak if the crawlspace isn't vented and dried properly — we check subfloor moisture, not just visible carpet or drywall.
- •River-adjacent properties near Sewell Park, Rio Vista Park, and the Blanco Shores area are the most flood-exposed spots in town; when the San Marcos River rises after a storm, basements and ground-floor units nearby can take on water fast.
- •Student rental duplexes and older apartment stock near Texas State see a disproportionate number of slow leaks — deferred maintenance on old water heaters and supply lines that go unnoticed until a ceiling stain shows up.
- •Hot, humid summers push mold growth fast once drywall or insulation stays wet more than 24-48 hours, so in San Marcos jobs we prioritize extraction and dehumidification before anything else, especially June through September.
