When East San Antonio's drainage can't keep up: how stormwater backup causes water damage in urban homes
San Antonio, United States - April 24, 2026 / SERVPRO of East San Antonio /
East San Antonio, TX, April 9, 2026 – Following the June 12, 2025 flooding that claimed 13 lives in San Antonio and prompted Bexar County Commissioners to approve $10 million in flood infrastructure improvements, SERVPRO® of East San Antonio is reminding property owners that stormwater backup remains a persistent threat to homes and businesses across the region.
The deadly June storm and subsequent county investment in rain gauges, flood projections, and proactive gate systems underscore what local restoration professionals already know: East San Antonio's aging drainage infrastructure, increasing urbanization, and intense rainfall patterns create conditions where stormwater can overwhelm municipal systems and cause significant property damage in hours.
"The June 12 tragedy highlighted how quickly stormwater can become dangerous in our area," said Billy R. Maggard Jr., franchise owner of SERVPRO of East San Antonio. "While Bexar County's $10 million investment addresses public safety infrastructure, homeowners still face immediate risks from drainage backup that can flood basements, crawlspaces, and ground-level areas during heavy rainfall. Our teams respond to these emergencies 24/7 because water damage doesn't wait for business hours."
Understanding drainage challenges in East San Antonio
Many homes in East San Antonio experience drainage issues due to aging infrastructure, urban growth, and heavy rainfall patterns in Bexar County.
Aging pipes and drains: Older systems may be partially blocked or not designed for current stormwater volumes.
Urban development: New construction and paved surfaces increase runoff toward homes.
Heavy rainfall: Storms can overwhelm even well-maintained drainage systems.
Early signs of drainage-related water damage include:
Inside the home: Standing water in basements or crawlspaces, damp floors or walls, slow-draining sinks or toilets.
Outside the home: Pooling water near foundations, yard flooding, water collecting near downspouts or driveways.
These signs indicate the need for immediate response from SERVPRO of East San Antonio, Texas to limit damage and restore affected areas.
How stormwater backup causes water damage
Stormwater backup can damage multiple areas of a home:
Floors and walls: Carpet and hardwood can warp or stain; drywall may swell or weaken.
Ceilings: Water can seep from upper levels, causing sagging or discoloration.
Foundations: Persistent water exposure may result in cracks or settling.
Unchecked water can lead to structural warping, damaged flooring or finishes, and higher repair costs. Common stormwater-induced scenarios include:
Basement flooding
Crawlspace intrusion
Garage or ground-level flooding
The company uses industrial-grade water removal equipment, advanced drying tools, and professional restoration techniques to restore homes quickly and safely.
Controlling stormwater backup at home
They also provide practical advice to homeowners, including:
Clearing gutters and downspouts regularly
Directing water away from foundations with extensions or splash blocks
Adjusting yard slopes and using drainage features like trenches or rain gardens
Using temporary barriers, functional sump pumps, and floor drains during heavy rain
By combining preventive measures with professional restoration services, homeowners can minimize water intrusion and restore their homes effectively after stormwater backup.
