OKC's expansive clay soil and flash-flood rain create predictable failure points. We solve them all with one system. ### Swampy lawns that kill grass Standing water turns yards into muddy, mosquito-prone patches and drowns landscaping. ### Cracked slabs and foundations Expansive clay soil and hydrostatic pressure push against foundations until they fail. ### Flooded basements after storms Flash-flood rain finds every weak point in your slab and floor-wall joint. ### Eroding beds and hardscapes Heavy runoff washes out flowerbeds, retaining walls, and driveway edges.

They graded it, ran a French drain to the curb, and it's bone dry now, even after the spring downpours." Mark T. Edmond, OK ★★★★★ "Water was getting into the basement after every heavy rain. The interior drain and sump pump they installed completely stopped it. Clean work, clear pricing." Denise R. Moore, OK ★★★★★ "Our old French drain was clogged solid with roots. They camera'd the line, hydro-jetted it, and saved us from a full replacement. Honest crew." Carlos M.

Do you offer free on-site drainage evaluations? Yes. We come to your property to assess the slope, soil, and water accumulation points, then determine precise grading and a gravity-fed exit before quoting. The evaluation is free across the OKC metro. How much does an exterior French drain cost in Oklahoma City? Exterior French drain installation runs about $10–$15 per linear foot for parts and labor, typically $1,000–$1,500 for a standard residential project. Price depends on length, depth, and concrete or landscaping obstacles. How much does an interior basement French drain cost? Interior French drains run about $50–$60 per linear foot, typically $5,000–$6,000 for a standard basement, because they require breaking and restoring the slab and usually pairing with a sump pump. Why does Oklahoma City clay soil cause drainage and foundation problems? Expansive clay swells when wet and shrinks when dry. That constant expand-and-contract cycle, plus flash-flood storms, pushes against slabs and foundations and traps standing water. Strategic drainage diverts groundwater before it can do structural damage. Will installing a French drain damage my sprinkler system? Trenching can cross irrigation lines, but we locate, reroute, and repair any sprinkler pipe we encounter as part of the turnkey job. Your irrigation system is fully restored before we finish. Which areas around Oklahoma City do you serve? We cover the Greater OKC metro, including Edmond, Norman, Moore, Yukon, Mustang, Piedmont, Midwest City, Del City, Bethany, Choctaw, Arcadia, and Guthrie across Oklahoma, Cleveland, Canadian, and Logan counties. ## Stop the swamp.
