Drainage Assessment in Seguin, TX

Before recommending any solution, we walk your property and assess the actual drainage situation. We look at where water is collecting, what the soil and grading conditions are, and what's causing the problem. You get a clear picture of the issue and honest options for addressing it — no charge for the assessment.

Seguin sits along the Guadalupe River in Guadalupe County between San Antonio and Austin, one of the oldest Anglo settlements in Texas, whose historic downtown square carries housing and drainage infrastructure dating to the mid-1800s. Guadalupe County sits at the edge of the Blackland Prairie where it transitions toward the South Texas Plains, and the Guadalupe River's floodplain running directly through the city adds real river-adjacent drainage considerations beyond the ordinary clay shrink-swell cycle found in most of Central Texas. Seguin's economy today blends manufacturing (Caterpillar and other industrial employers operate here), agriculture, and a growing bedroom-community role as the San Antonio-Austin corridor continues to develop, with the city's older river-adjacent core showing notably different drainage conditions than its newer subdivisions farther from the water. The Guadalupe River's own flood history through Seguin is a documented, recurring civic concern distinct from the ordinary clay drainage issues found away from the riverbank.

What We Look For During a Drainage Assessment

We check the grade around your foundation, the slope of the yard toward or away from the house, downspout placement and outlet conditions, soil compaction and permeability, existing drainage features that may be failing or undersized, and low points where water naturally concentrates. In Guadalupe County, clay-heavy soils often make drainage problems worse — we factor that into our evaluation. We also ask questions that don't show up in a visual walk-through: how long standing water typically takes to clear, whether the problem is worse in a particular season, and whether it's gotten worse recently or has been consistent for years — that history often narrows down the cause faster than the visual inspection alone.

• Foundation grade and slope — checked on every side, not just the side where the problem is visible.
• Downspout placement and outlet condition — a surprisingly common root cause hiding in plain sight.
• Soil compaction and permeability — tested by hand in a few spots, not just assumed from the county's general soil type.
• Existing drainage features — checked for whether they're actually functioning or just present.
• Low points and water-concentration areas — mapped across the whole property, since a problem at one spot sometimes originates somewhere else entirely.

What You Get After the Assessment

After walking the property, we explain what we found in plain terms and give you our honest recommendation. If a simple fix like regrading or extending a downspout will solve the problem, we'll tell you that. If you need a more involved drainage system, we'll explain why, what it would include, and what it would cost. There is no pressure to hire us after the assessment. You'll also get a plain explanation of why the problem is happening, not just what to do about it — understanding the cause is what lets you evaluate whether a second opinion's recommendation actually makes sense.

• A plain-language explanation of the cause, not just a recommended fix.
• An honest read on whether a simple correction will solve it, or whether the problem needs a real system.
• A written scope and price if you choose to move forward — no verbal-only estimates.
• No obligation and no pressure — the assessment stands on its own whether or not you hire us.
