Professional Drainage Solutions & Grading in Clifton, Virginia
Standing water, soggy side yards, washed-out beds, water at the foundation — on Clifton's clay-loam that stays wet in low spots, drainage problems do not fix themselves. We design and install French drains, dry creek beds, downspout extensions, and regrading that moves water where it belongs. No matter where you are in Clifton, you get the same crew, the same standard, and a written quote within 24–48 hours of the walkthrough.
The Short Answer
Yard drainage solutions in Clifton typically include French drains, downspout extensions, and regrading — and a standard exterior French drain starts at $3,500 (final price depends on trench length, depth, and soil conditions), while simple downspout extensions and spot regrading often run a few hundred dollars. The right fix depends on where the water is coming from: surface runoff usually needs regrading so the ground slopes at least 6 inches over the first 10 feet away from your foundation, while wet spots fed by roof water or a high water table typically need a French drain or buried downspout extension. Lawn Theory diagnoses the actual cause on-site before recommending a fix, so you're not paying for a drain you don't need.

Drainage Solutions & Grading in Clifton — Common Questions
How much does a French drain cost in Clifton?
Exterior French drains start at $3,500 for a typical 100-foot run — final price depends on trench depth, soil conditions, and whether the drain has to cross a driveway, patio, or other hardscape. Clay-heavy soil, tree roots, and buried utilities can each add to the cost. We give you an exact number after an on-site assessment — never a phone quote.
Will a French drain damage my lawn or landscaping?
There's a trench, so there is some disruption, but it's temporary. We cut as narrow a trench as the job allows, stage the excavated soil on tarps to protect surrounding turf, and restore every disturbed area with fresh sod or seed once the drain is backfilled. Most lawns look fully recovered within a few weeks.
How long does a French drain or regrading project take?
A single-zone French drain or downspout extension is typically a one-day job. A whole-yard regrade with multiple drain runs can take 2-4 days depending on square footage and how much soil needs to move. We give you a firm timeline in your written quote. Our crews work Clifton regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Why does my Northern Virginia yard flood even though my neighbor's doesn't?
It's almost always about grade and soil, not luck. Homes lower in a subdivision's original grading plan naturally collect runoff from higher lots, and Fairfax County's dense clay subsoil compounds the problem by draining slowly. Older homes also sometimes have settled or reverse-graded areas near the foundation that were never corrected. An on-site assessment identifies the specific cause on your lot.
Can poor drainage really cause foundation damage?
Yes. When water isn't directed away from the house, the soil next to the foundation stays saturated, which builds hydrostatic pressure against basement walls and can lead to cracking, leaks, and long-term structural issues. Extending downspouts and correcting grade near the foundation are two of the most cost-effective ways to prevent this.
Will a French drain fix my soggy yard?
If the problem is subsurface water moving through clay, yes — properly built with fabric, washed gravel, and a real outfall. If the cause is surface grading or roof water, a French drain alone won't; that's why we diagnose the path first. Our crews work Clifton regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Do I need a permit for drainage work in Northern Virginia?
Most residential yard drainage and minor regrading doesn't require permits, but work affecting significant grade changes, resource protection areas, or discharge to storm systems can. We flag it during design and handle the process when it applies. Our crews work Clifton regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
