Yard Drainage in St. Louis
Learn what causes standing water and soggy lawns in St. Louis and when grading, drains, or downspout work may help.
Why water sits in a yard
Standing water usually means water is arriving faster than the property can absorb or move it away. Common causes include low spots, compacted or slowly draining soil, concentrated roof runoff, uphill flow, and poor surface grade.
What to check first
- Watch where water enters the wet area during rain.
- Check downspout discharge locations.
- Look for obvious low spots or settled soil.
- Note how long the water remains after rain.
- Identify where water could safely discharge.
Common fixes
Depending on the cause, solutions may include grading, catch basins, French drains, downspout routing, or a combination.
Questions homeowners often ask
Can I diagnose this from photos alone?
Photos can help show symptoms, but slope, elevation, soil, discharge options, utilities, and rainfall behavior may require an on-site evaluation.
Should I get more than one estimate?
For meaningful drainage work, comparing scope—not just price—can be useful. Ask each provider what problem they believe they are solving and where the water will ultimately go.
Who should verify permits?
Ask the provider who will be responsible for checking and obtaining any permits or approvals required for the specific property and scope.
Drainage design depends on site conditions. Use the estimator for planning or request an on-site assessment from an independent provider.
