French Drain
$20-$60
per linear ft
Standing water, soggy patches, and foundation seepage don't fix themselves. The right drainage solution depends on your yard's slope, soil type, and where the water is coming from. This guide breaks down six proven methods — from simple yard grading to engineered French drains — with real cost ranges, DIY difficulty ratings, and guidance on when each one makes sense. Planning a project that involves gravel? Most drainage work does.
7 Signs Your Yard Needs Drainage Work
Most homeowners don't think about drainage until something goes wrong. If you recognize two or more of these signs, you have a drainage problem that will only get worse with time.
Standing water 48+ hours after rain
A healthy lawn drains within 24-48 hours. Water pooling longer means compacted soil, clay, or a low spot trapping runoff.
Spongy, squelchy spots when you walk
Soil that feels like a wet sponge underfoot is waterlogged. Roots are suffocating and grass will yellow within weeks.
Yellowing grass in flat or low areas
Excess moisture deprives roots of oxygen. If patches turn yellow after every rain (not drought), drainage is the cause.
Visible erosion channels or bare soil
Water carving ruts across your yard means concentrated flow with no outlet. Left unchecked, it worsens every storm.
Water seeping into basement or crawl space
The most expensive sign to ignore. Foundation water damage costs $5,000-$15,000+ to repair. Drainage costs a fraction.
Mosquito breeding and pest problems
Mosquitoes breed in as little as a tablespoon of standing water. Persistent wet zones create a pest factory.
Mold, mildew, or musty smell near foundation
Moisture wicking up foundation walls creates mold conditions inside. This is a health issue, not just a cosmetic one.
Don't wait for foundation damage. A $2,000-$5,000 drainage fix now can prevent $10,000-$30,000 in structural repairs later. If water is reaching your foundation, address it before your next spring season.

French Drain
$20-$60/linear ftPerforated pipe in a gravel-filled trench that collects and redirects subsurface water underground.
Best for: Persistent soggy areas, water pooling against foundations, retaining wall backfill
Pros
- Invisible once installed (no surface disruption)
- Handles heavy subsurface water
- Works on flat or sloped yards
Cons
- Requires trenching (labor-intensive)
- Can clog without proper filter fabric
- Needs a downhill outlet or sump pump
Dry Creek Bed
$5-$15/linear ftShallow channel lined with decorative stones and boulders that guides surface water along a natural-looking path.
Best for: Surface runoff from slopes, downspout discharge, yards where aesthetics matter
Pros
- Doubles as a landscape feature
- Low cost and easy DIY
- No underground pipes to maintain
Cons
- Only handles surface water (not subsurface)
- Requires periodic debris clearing
- Not effective for standing water problems
Yard Grading
$500-$3,000 (small) / $3,000-$10,000+ (whole yard)Reshaping the soil surface to create slope away from structures so water flows to designated drainage areas.
Best for: Flat yards pooling near foundations, new construction, complete landscape overhauls
Pros
- Addresses root cause of poor drainage
- No ongoing maintenance
- Can eliminate need for other solutions
Cons
- Disrupts existing landscaping
- May require heavy equipment
- Permits may be needed for major regrading
Rain Garden
$3-$5/sq ft (DIY) / $10-$20/sq ft (pro)A shallow, planted depression that collects runoff and allows it to soak into the soil through native plants and amended soil.
Best for: Downspout runoff, gentle slopes, eco-friendly drainage, pollutant filtering
Pros
- Beautiful and eco-friendly
- Filters pollutants from runoff
- Attracts pollinators and wildlife
Cons
- Needs 10+ feet from foundation
- Plants require 2-3 years to establish
- Not for heavy clay soil without amendment
Channel Drain
$30-$100/linear ft (installed)A linear grate-covered trench drain that intercepts surface water across driveways, patios, or walkways.
Best for: Driveway runoff, patio edges, garage entries, pool decks
Pros
- Handles high-volume concentrated flow
- Low profile (flush with surface)
- Ideal for hardscape drainage
Cons
- Requires concrete cutting for retrofit
- Most expensive option per foot
- Grate cleaning needed seasonally
Catch Basin
$150-$500 (DIY) / $1,000-$4,000 (pro installed)A below-grade box with a grate that collects surface water and pipes it to a discharge point.
Best for: Low spots that pool, downspout collection, connecting multiple drain lines
Pros
- Captures water at specific problem points
- Sediment settles in basin (protects pipes)
- Can connect to French drain or storm sewer
Cons
- Needs periodic cleanout (leaves/debris)
- Requires slope to outlet or sump pump
- Single-point fix (may need multiples)
Pro tip: Most properties benefit from combining 2-3 solutions. A typical setup: yard grading to direct water + a French drain at the low point + a catch basin to collect downspout runoff. Use our landscaping cost calculator to estimate a combined system.
French Drain Anatomy: Cross-Section Diagram
A French drain is only as good as its layers. Skip the filter fabric or use the wrong gravel and it clogs within 2-3 years. Here's what a properly built French drain looks like in cross-section.
Compacted base
Tamped crushed stone or firm subgrade. Slight slope (1% min) toward outlet.
Perforated pipe
Rigid PVC or corrugated with holes facing down. Wrapped in filter sock.
Drainage gravel
Clean 3/4" washed stone. No fines — dirty gravel clogs the pipe.
Filter fabric
Non-woven geotextile. Wraps gravel completely to keep soil out.
Native backfill
Original soil returned above the fabric. Grade away from structures.
Sod or seed cap
Topsoil and sod to restore lawn surface. Invisible when done.
Gravel matters. Use clean, washed 3/4" stone (no fines). “Crusher run” or “road base” gravel has dust that clogs perforations. Calculate how much you need with our gravel calculator.

DIY vs. Hire a Pro: Decision Guide
Drainage work is physically demanding but not technically complex — most of it is digging, grading, and laying pipe. The key question: do you have the time and physical ability to move dirt for 1-3 days? If yes, DIY saves you 40-60%. If not, professional landscapers can knock it out in a day.
DIY It
- Dry creek bed on a gentle slope (the easiest drainage project)
- Single catch basin at a low spot in the yard
- French drain under 50 ft on accessible, non-rocky ground
- Rain garden in a naturally low area with sandy/loamy soil
- Extending downspouts with solid pipe to a pop-up emitter
- Small grading fix along one wall (under 500 sq ft)
Hire a Pro
- French drain longer than 100 ft or through rocky/clay soil
- Yard grading near foundation walls (incorrect slope = foundation damage)
- Channel drain retrofit into existing concrete or pavers
- Any drainage work that connects to municipal storm sewer (permit required)
- Multiple drainage systems that need to integrate and slope correctly
- Water entering basement or crawl space (liability and waterproofing expertise)
“Water always wins. You can't fight gravity — you can only redirect it. Get the slope right and the water moves itself.”
Tool Rentals That Make DIY Feasible
Renting a trencher turns a 2-day hand-digging ordeal into a 3-hour project. Available at Home Depot, Sunbelt, and most equipment rental shops.
Trencher (for French drains)
Saves 6-8 hours of hand digging
Plate compactor
Essential for gravel base
Laser level or transit
Ensures proper slope
Sod cutter
Clean sod removal for reinstallation
Call 811 before you dig. Underground utility lines (gas, electric, water, cable) are invisible and dangerous. The 811 “Call Before You Dig” service is free and required by law in all 50 states. They'll mark utility locations within 2-3 business days.
Bottom line: If you're comfortable with a shovel and have a weekend to spare, a French drain or dry creek bed is a satisfying DIY project that saves $1,000-$3,000. For anything involving foundation proximity, heavy clay, or municipal connections, the cost of a pro is insurance against doing it twice.
Quick Reference: Which Solution for Your Problem?
Not sure which drainage method to use? Match your specific problem to the right solution below. Most yards benefit from combining 2-3 approaches.
Water pooling on the surface after rain
Start with grading. Add a catch basin at the low spot if grading alone isn't enough.
Soggy soil / spongy lawn (subsurface water)
French drain is the go-to fix. Rain garden works if the area is 10+ ft from your foundation.
Water against foundation or in basement
Grade soil away from foundation first. Add a French drain if subsurface water persists.
Driveway / patio flooding
Channel drain across the driveway edge. Connect to solid pipe discharging downhill.
Downspout dumping water near house
Extend downspout underground with solid pipe to a pop-up emitter 10+ ft from foundation.
Slope sending runoff across the yard
Dry creek bed across the slope's base. Cheapest and most attractive solution.
