DRAINAGE & GRADING · FAIRFAX, VA

Drainage and Grading Contractor in Fairfax, VA

French drains, regrading, and permeable surfaces that move water off Fairfax clay and away from the house.

Water that pools in the yard for days, washes out mulch beds, or sits against the foundation is common in Fairfax, where much of the soil is clay that drains slowly. We find where the water comes from and where it can legally and practically go, then fix it with regrading, French drains, dry wells, or permeable surfaces. Drainage is also built into every driveway, wall, and patio job we do.

Why Fairfax yards hold water

Fairfax County's own guide to marine clay says surface drainage is often a problem because water percolates very slowly through the clays and does not drain well from level yard areas. The county also maps other shrink-swell clays outside the marine clay areas.

On soil like that, a yard that is flat or slopes toward the house will hold water. The fix usually starts with grade: shaping the ground so it falls away from the foundation, then giving the water a defined path off the property.

Who is responsible for the water

Fairfax County's stormwater FAQ is direct about it: private drainage and erosion problems are the property owner's responsibility, and water sent from gutters or downspouts onto a neighbor's lot is a civil matter between owners. The county maintains public storm systems within drainage easements, and VDOT maintains the systems in public street rights-of-way. So we design every drain to discharge on your property or into a proper outlet, never by moving the problem next door.

Bigger jobs, stream buffers, and digging safely

Fairfax County may require a land disturbance permit for projects disturbing 2,500 square feet or more, and land near streams can fall in a Resource Protection Area, where disturbance needs approval from Land Development Services. Most yard drainage jobs are smaller, but we check before we design. Drain trenches cross utility lines, so we contact VA811 before any digging and work around marked lines. Private lines, like irrigation or lamp-post wiring, are not marked, so we ask you about them.

What does drainage work cost?

It depends on how far the water needs to go. What moves the price:

  • Length of French drain or pipe run
  • How much soil gets regraded
  • Where the water can discharge
  • Digging around existing hardscape, roots, or utilities
  • Permeable surfaces or dry wells

Every job is priced after we see it. The estimate is free, and we walk you through the options before you commit to anything.

Drainage & Grading in Fairfax: common questions

Will Fairfax County fix drainage problems on my property?

Usually not. The county's stormwater FAQ says private drainage and erosion issues are the owner's responsibility, and runoff from a neighbor's downspouts is a civil matter. The county maintains public systems in its easements, and VDOT handles street drainage.

Do I need a permit for a French drain in Fairfax County?

Most residential drainage jobs do not, but larger regrading can need a land disturbance permit, and work in a Resource Protection Area needs county approval. Inside the City of Fairfax, the City has its own process. We confirm with the right office before quoting.

What does drainage work cost in Fairfax?

Mostly the length of the drain run, how much soil gets regraded, where the water can discharge, and what is in the way: patios, roots, and utilities. Dry wells and permeable surfaces add to it. Summit does not publish set prices, and Joseph's estimate is free.

Can you send my water to the street?

Sometimes. A drain can outlet at the curb or into a swale when the grade allows and the outlet is permitted for that location. Otherwise we use a dry well or a permeable surface to let water soak in on your lot. We explain which fits your yard.
