License-checked pros, shown in a neutral order. You do the hiring.
Williamsburg sits in the Hampton Roads region, and these are the foundation & drainage companies that cover it. We check each license with the state and lay out the cost ranges before you ever make a call.

Virginia clay soil and heavy summer storms push a lot of water at a house, and drainage work is how you move it away from the foundation before it gets into the basement or crawl space. A foundation and drainage pro reads where the water goes and gives it somewhere better to be.

Williamsburg prices track these statewide ranges. These are rough ranges, not quotes. What you actually pay swings with the trench depth, the length of the run, how easy the yard is to reach with equipment, and where the water can discharge. Virginia red clay and a high water table near the coast push the harder end. Get two or three written quotes before you decide.
Signs you might need to hire a pro
- Standing water or soggy spots in the yard a day after it rains
- Water in the basement or crawl space, or a musty smell down there
- A foundation wall that is cracking, bowing, or staining
- Mulch and soil washing away, or gutters dumping right at the foundation
- The yard slopes toward the house instead of away from it
Before you sign
Licensing in Virginia
Any contracting job of 1,000 dollars or more has to go to a business licensed with the Virginia DPOR Board for Contractors, and under that none is required. The class on that license is a dollar ceiling, not a grade of quality. Class C covers single jobs under about 10,000 dollars, Class B under about 120,000, and Class A has no ceiling, so a small Class C outfit is not worse than a Class A, it just takes smaller work.
Drainage and foundation work can fall under several Virginia contractor classifications. A legitimate pro may hold Highway Heavy (which lists drainage systems, foundations, and grading), Residential or Commercial Building Contractor, Landscape Service Contracting, or Plumbing, depending on the work.
Verify it yourself. Look up any license at the Virginia DPOR lookup and ask for proof of insurance before you hire.

Common questions about foundation & drainage companies in Williamsburg
Do I need a French drain, or is regrading enough?
Where the water sits decides it. Surface pooling from a yard that slopes toward the house often fixes with regrading and downspout extensions. Water getting into a basement or crawl space usually needs a drain. A good contractor measures the slope before quoting.
Roughly what does drainage work cost in Virginia?
Exterior French drains run about 30 to 90 dollars per foot and interior or basement drains about 40 to 100 dollars per foot, so most jobs land somewhere between a few hundred dollars and several thousand. Depth, soil, and length swing it a lot, so get two or three written quotes.
Should I call a landscaper or a foundation company?
If the water is in the yard, a drainage or grading pro is usually right. If it is coming through the foundation or the walls are cracking, that is foundation and waterproofing work. Some companies do both, so ask up front.
How long does a French drain last?
Installed right, with filter fabric and clean gravel, a French drain can last thirty years or more. The usual killer is silt or tree roots clogging the pipe, so ask what maintenance it will need.
Will I need a permit?
Sometimes, depending on where the water discharges and whether it ties into a storm system or sits near a property line or wetland. Your contractor should handle permits, so ask them to confirm before work starts.
