French Drain vs. Regrading — Which Do You Need?

These are two of the most common drainage fixes, and they solve genuinely different problems — using the wrong one means spending real money without actually fixing the issue. Here's how to think about which situation you're in.

When Regrading Is the Right Call

Regrading — reshaping the yard's slope so water flows away from problem areas instead of pooling — is the right fix when the core issue is surface water: rain sheeting across a flat or improperly sloped yard, pooling in a low spot after storms, or running toward the foundation because the ground slopes the wrong way. If water is visibly sitting or flowing ON TOP of the ground, regrading addresses the cause directly, often at lower cost than a full French drain system.

When a French Drain Is the Right Call

A French drain is the right tool when the problem is subsurface — water saturating the soil itself, a persistently soggy area even without visible surface pooling, water seeping into a basement or crawl space through the soil rather than running in over the top, or a yard where regrading alone can't create enough slope to solve the problem (flat lots, tight lot lines, or structures in the way). Many yards genuinely need both: regrading to handle surface flow and a French drain to handle what's happening below ground. A real drainage inspection should identify which kind of water problem — or combination — is actually present before recommending either fix.
