Drainage Assessment in Sherman, 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.

Sherman is home to Austin College, one of the oldest institutions of higher education in Texas, founded in 1849, and the tree-lined streets around the historic campus carry some of the city's oldest housing stock, on infrastructure that predates even the area's early-1900s rail and manufacturing boom. Sherman sits near the Texoma region's namesake Lake Texoma, though the lake itself sits far enough north along the Red River that its influence on in-town Sherman drainage is more indirect than the lake-adjacent DFW suburbs closer to Dallas. Loy Lake, a smaller reservoir just outside town, has a more direct localized effect on nearby neighborhoods' groundwater. Grayson County's Blackland clay here is real but slightly less severe than the deep black gumbo found in Collin and Dallas counties to the south.

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 Grayson 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.
