Serving All San Marcos Neighborhoods

From the river corridor near TXST to the newer master-planned communities on the city's perimeter, we've remediated mold throughout San Marcos.
Our crews understand the local flood history, rental housing challenges, and soil conditions that drive mold risk in each area.

University / TXST Campus Area

The neighborhoods surrounding Texas State contain some of the oldest, densest housing in San Marcos. Student rentals here commonly feature aging plumbing, inadequate bathroom ventilation, and slow landlord maintenance response. Mold beneath flooring and inside walls is a routine finding after any significant moisture event or wet semester.


Rio Vista / San Marcos River Corridor

Neighborhoods along the San Marcos River sit beside one of the highest-flow spring systems in Texas, keeping the water table elevated year-round. Properties near the floodplain face significant risk during Central Texas rain events. Homes in this corridor that experienced the 2015 floods should get a professional moisture inspection even if repairs were completed at the time.

Blanco Vista

A master-planned community on San Marcos's north side near the Blanco River. The river's catastrophic 2015 flooding puts many Blanco Vista properties in an elevated moisture risk zone. Clay-heavy soils throughout this area expand and contract with moisture cycles, creating foundation-edge intrusion points that allow water in over time.


Trace

One of San Marcos's largest newer master-planned communities, with homes across multiple active builder phases on the city's northwestern edge. Framing exposed to wet weather before enclosure can carry hidden wall moisture from day one. The community's rolling terrain creates variable drainage, with low-lying lots collecting stormwater runoff during heavy rain events.

Midtown San Marcos

Established midtown neighborhoods feature older homes, many dating from the mid-20th century, with aging roofs, original plumbing, and years of deferred maintenance creating chronic moisture intrusion pathways. Pier-and-beam foundations common in this era are especially vulnerable to ground moisture during wet seasons, and musty odors here frequently trace back to sub-floor accumulation.

Spring Lake Hills / Aquarena Area

Sitting directly above one of Texas's most active spring systems, these neighborhoods experience persistently elevated soil moisture that works against foundations and crawl spaces year-round. Properties nearest the spring discharge zones carry the highest ambient moisture levels and should be proactively monitored for mold, especially in below-grade or pier-and-beam foundation areas.

Hunter Road Corridor

San Marcos's growing east side has seen significant new residential development along the Hunter Road corridor. Flat terrain in portions of the area channels stormwater toward foundation perimeters during heavy rain events, and newer construction here benefits from a professional moisture inspection within the first year of occupancy.

Downtown / Wonder World Drive Area

The downtown district and Wonder World Drive neighborhoods hold a significant inventory of older commercial and residential buildings. Flat commercial roofs with aging drainage are a common source of water intrusion, while older homes here typically lack adequate bathroom ventilation. We serve both residential and commercial clients throughout central San Marcos.

San Marcos Activity Center / Sessom Drive

The Sessom Drive corridor links some of San Marcos's oldest residential neighborhoods to the TXST campus, with homes ranging from historic bungalows to mid-century rentals. Rapid tenant turnover means plumbing leaks and roof issues can go unreported for an entire semester, allowing mold to take hold behind walls before anyone notices.

Frequently Asked Questions

Does homeowner's insurance cover mold remediation in San Marcos?

It depends on the cause. Most Texas homeowner's policies cover mold that results from a "sudden and accidental" water event  like a burst pipe or appliance failure. Mold from flooding (such as Brushy Creek overflow) typically requires a separate NFIP flood insurance policy. We provide detailed documentation to support your claim and work directly with your adjuster.

Can a brand-new San Marcos home really have mold?

Yes and it's more common than most buyers realize. During San Marcos's rapid construction booms, framing lumber often gets wet before drywall is installed. If the structure isn't adequately dried first, mold grows inside the walls before you ever move in. If your new home has an unexplained musty smell, don't assume it will go away — call us for an inspection.

How long does mold remediation take in San Marcos?

Small, contained areas (like a bathroom or garage) typically take 1–3 days. Moderate projects involving multiple rooms run 3–7 days. Severe cases like post-flood whole-home remediation or new construction moisture issues can take 1–3 weeks. We give you a precise timeline on day one so you can plan accordingly.

 

Is mold remediation required before selling a home in San Marcos?

Texas law requires sellers to disclose known mold issues on the Seller's Disclosure Notice. While remediation isn't legally mandated, a positive mold test can kill a sale in San Marcos's competitive market. Most buyers now request mold inspections, and having a clearance certificate dramatically improves your negotiating position and protects you from post-sale liability.

Can mold come back after remediation?

Not if the moisture source is corrected. Mold remediation removes existing mold but if the leak, flooding, or humidity issue isn't fixed, it can return. Our remediation always includes identifying and addressing the root moisture cause, and we offer a clearance certificate plus a post-remediation warranty for your peace of mind.

 

I'm a landlord with TXST student rentals. What are my mold obligations in Texas?

Texas landlords are required under the Texas Property Code to maintain rental properties in a condition that is safe and sanitary, which includes addressing mold resulting from maintenance deficiencies. Mold arising from structural issues, roof leaks, or plumbing problems is generally a landlord responsibility. Failure to remediate known mold can expose landlords to lease termination claims, rent abatement demands, and liability. We provide full, insurance-grade documentation for landlord records and Texas disclosure compliance.
