Drainage Assessment in Lewisville, TX

Before recommending any solution, a local contractor walks your property and assesses the actual drainage situation, then gives you an honest answer on whether a french drain is the right fix — or says so if another approach would work better. You get a clear picture of the problem and honest options for addressing it at no charge.

Lewisville sits along Lake Lewisville in Denton County in the northern DFW Metroplex, on Blackland Prairie clay with a substantial lake-adjacent water table influence, a suburb that's grown steadily since the 1960s from a modest lake town into a major Metroplex city. That decades-long growth pattern gives Lewisville a genuinely mixed housing stock — older, more established neighborhoods near the lake and original town center with infrastructure well behind current standards, alongside newer subdivision development on the city's outer edges. North Texas's intense spring thunderstorm season adds real volume on top of the lake's already-elevated water table for shoreline-adjacent properties, while inland Lewisville deals with the same highly expansive clay found through the rest of Denton County. Lewisville Lake Toyota Music Factory and the surrounding Lewisville Lake Environmental Learning Area both sit near the dam that impounded Lake Dallas — later renamed Lewisville Lake — in the 1950s, a project that fundamentally redrew this stretch of the Elm Fork Trinity's natural drainage and turned what had been a working farm-town core into a lake-recreation economy within a single generation. Old Town Lewisville, the original 1800s townsite predating the reservoir by nearly a century, sits on notably different, non-lake-influenced ground than the shoreline development built up since the 1970s, giving the city two genuinely distinct drainage histories within its borders.

What Gets Checked During a Drainage Assessment

A drainage assessment checks the grade around your foundation, the slope of the yard, soil type and permeability, downspout placement, existing drainage features, and low points where water naturally concentrates. In Denton County's clay-heavy soils, particular attention goes to how water is moving through the soil versus across the surface — that distinction determines whether a french drain, catch basin, or surface regrading is the right solution.

What You Get After the Assessment

After walking the property, you'll get a plain-terms explanation of what was found along with an honest recommendation. If a french drain is the right solution, you'll learn where it should go, how it will be configured, and what it will cost. If another approach is more appropriate, you'll be told that too. There is no pressure to hire anyone after the assessment.
