Drainage & grading · Central Virginia
French drains, regrading, buried downspouts, and erosion control built for Virginia clay — where water does not soak in and has to be given somewhere to go.
The reason yards stay wet here is not rainfall, it is the soil. Central Virginia red clay has one of the lowest infiltration rates of any soil type in the state. Water that would disappear into sand within minutes sits on clay for days, and every graded-flat subdivision lot compounds it by removing the topsoil that used to hold some of that volume.
The failure most homeowners never connect is the roof. A typical house sheds well over a thousand gallons in a single inch of rain, and if the downspouts discharge at the foundation, that entire volume lands against the wall where you least want it. Fixing the downspouts is frequently more than half the solution and the cheapest part of the job.
We start with the grade. If the ground slopes toward the house, that gets corrected before anything gets buried, because a drain installed into a bad grade is a temporary fix on a permanent problem. Where a drain genuinely is the answer, we build it right — clean stone, filter fabric, real pitch, and an outlet that daylights instead of dead-ending into saturated clay.
A perforated pipe in a gravel trench, wrapped in filter fabric, pitched to daylight. The standard fix for a chronically wet area or water tracking toward a foundation. Done properly it disappears into the lawn; done cheaply it silts up in two years.

Reshaping the ground so water moves away from the house instead of pooling. Often the real fix when people ask for a drain — if the grade runs the wrong way, no pipe compensates for it forever.
Read MoreRoof water is the single largest volume hitting most yards, and dumping it at the foundation causes more damage than any other drainage mistake. We bury the lines and carry the discharge out to daylight or a pop-up emitter.

Get StartedWhy Virginia yards flood, what French drains cost, and when regrading is the better answer.
Ask a questionAlmost always the clay. Central Virginia soil is dense red clay with a very low infiltration rate — water that would soak into sandy soil in minutes sits on top of clay for hours or days. Add a lot that was graded flat during construction, roof downspouts discharging at the foundation, and topsoil that was scraped off and never replaced, and you get standing water after every serious rain.
Most residential installs run $30 to $70 per linear foot depending on depth, whether we are trenching through lawn or hardscape, and how far we have to carry the discharge to reach daylight. A typical 60-foot run to correct a wet side yard lands somewhere around $2,500 to $4,000. Hand-digging around mature tree roots or utilities costs more than open trenching.
Regrading first, if the grade is the problem. Water that pools because the ground slopes toward the house needs the ground fixed, not a pipe added — a drain in a bad grade is a bandage that eventually fails. Drains are the right answer for a genuinely low area you cannot regrade, a spring or seep, or water arriving from an uphill neighbor. We look at the grade before recommending anything.
Minor leveling with topsoil and seed runs $500 to $2,000 for a typical residential lot. Actual regrading that moves meaningful volume — reshaping drainage, cutting and filling, machine work — runs $2,500 to $8,000 depending on how much material has to move and whether it can be sourced or hauled on site. Fill dirt and topsoil are usually the biggest line items.
Exterior drainage and grading solve a large share of basement water problems, because most of it is surface water arriving at the foundation from a bad grade or a downspout dumping alongside the wall. What exterior work will not solve is a high water table, hydrostatic pressure, or a failed foundation waterproofing membrane — those need an interior system or a foundation contractor. We will tell you honestly which one you have.
A downspout burial or a short French drain is usually a one-day job. A full side-yard system runs two to three days. Regrading with dry creek beds and plantings takes closer to a week. We do not trench in saturated ground — working wet clay destroys its structure and leaves you with a worse lawn than you started with, so heavy rain moves the schedule.
