Drainage problems usually reveal themselves gradually. Standing water that lingers a day after rain might seem like a minor annoyance. But repeated saturation cycles damage turf, erode soil, attract pests, and can eventually threaten the foundation. Knowing what to watch for — and when to take it seriously — can save significant money and headaches.

Schertz grew up around a rail depot and later a major Army logistics base, Camp Bullis and the nearby Randolph Air Force Base both shaping the town's mid-1900s development before its more recent transformation into a fast-growing San Antonio-metro suburb. Cibolo Creek, which also runs past Seguin further east, defines Schertz's eastern boundary, but the city sits meaningfully closer to San Antonio's urban edge, meaning its newest subdivisions — largely built since the 2000s along the I-35 corridor — sit on ground graded more recently and more consistently than the historic river-town core found in Seguin. Guadalupe, Bexar, and Comal counties all meet near Schertz, and drainage standards and infrastructure age vary depending on which of the three a given property falls in.

Common Drainage Warning Signs

These are the signs we hear about most often from Schertz homeowners:

Standing water in the yard more than 24-48 hours after rain

Water that doesn't drain within a day or two usually points to a grading or subsurface drainage issue rather than just a heavy storm.

Water pooling against the foundation or in a crawlspace after rain

This is one of the more urgent drainage signs, since prolonged moisture against a foundation can contribute to other structural issues over time.

A consistently soggy low spot in the yard, even during normal weather

A chronically wet spot (as opposed to a spot only wet right after heavy rain) is often solved with a French drain or rain garden rather than regrading alone.

What Causes These Problems

Most drainage problems in Schertz and Guadalupe County come down to one or more of three conditions: soil that drains slowly (clay is the primary culprit in this region), low spots in the grading where water naturally concentrates, or runoff from neighboring lots, driveways, or roof drainage that overwhelms the yard's capacity to absorb. Identifying which condition applies determines the right solution — and a proper assessment before any work begins is the only way to get that right.
