French Drain Cost in Spring Hill, TN

What residential French drain installation actually costs in Spring Hill: per-foot rates, full project ranges, and the variables that move the number up or down.

Pricing for French drain installation in Spring Hill follows the same general structure as most middle Tennessee markets, with some local quirks. The fragipan layer that runs through every Maury silt loam yard here means trenches usually need to be deeper than national averages assume, which adds modestly to excavation time. The labor rate is below coastal averages but above rural Tennessee, putting Spring Hill in the middle of the cost curve.

This guide gives the ranges we quote most often. Final pricing always comes from a free on-site walk because lot conditions, soil profile, and outlet options vary too much to quote sight-unseen.

Per Linear Foot Pricing

System TypePer Linear Foot
Exterior yard French drain$30 to $45
Exterior foundation drain$40 to $55
Interior crawlspace drain$50 to $75
Interior basement drain$65 to $95
Solid pipe outlet run$18 to $28

Full Project Ranges

Project TypeTypical Total
Short single-leg foundation drain (40 to 60 ft)$2,500 to $4,500
Yard interceptor drain (60 to 100 ft)$3,000 to $5,500
Full perimeter foundation drain (150 to 220 ft)$5,500 to $11,000
Crawlspace interior drain with sump pit$4,800 to $9,500
Combined French drain + yard drainage + grading$6,500 to $14,000
Yard drainage only (catch basins, no French drain)$1,800 to $6,500

What Drives the Price Up or Down

  • Total linear feet. The biggest single variable. Most cost scales linearly with length once the crew is on site.
  • Trench depth. A 36 inch trench costs roughly 20 to 30 percent more per foot than an 18 inch trench because of the equipment time and the gravel volume.
  • Outlet routing distance. If the daylight outlet is 100 feet from the last collection point, that solid pipe run adds linear cost (lower than perforated pipe rate but not zero).
  • Hardscape demolition. Trenching across a driveway, walkway, or patio requires saw cutting and resurfacing, which adds $400 to $1,500 per crossing.
  • Surface restoration. Sodded restoration adds about $4 to $7 per square foot over seed-and-straw.
  • Sump pit and pump. Adds $1,500 to $2,400 if the system has no gravity outlet, plus $700 to $1,400 for a battery backup pump.
  • Permits. Most residential projects do not need them. Larger projects crossing the one acre disturbance threshold require a county or TDEC permit, which adds $200 to $800 in administrative cost.

For comparison, the national pricing data from University of Tennessee Extension drainage publications aligns with our experience: middle Tennessee residential drainage projects cluster in the $2,500 to $9,000 range for single-system installations.

Cost Comparison: French Drain vs Alternatives

On lots where surface grading and downspout extensions can solve the problem, those alternatives run $800 to $2,500 and are worth trying first. On lots where fragipan-trapped subsurface water is the issue (most chronic Spring Hill drainage problems), the surface fixes do not work and the French drain is the actual solution. The cost difference is the cost of solving the problem versus the cost of partially treating a symptom.

French Drain Cost FAQ

What is the average cost of a French drain in Spring Hill TN?
The average residential French drain project in Spring Hill runs $4,200 to $5,800 for a typical single-side foundation drain with a proper outlet. The full range across all project types is $2,500 to $8,500. National averages quoted by Forbes, Angi, and HomeAdvisor sit around $5,000, which lines up with the Spring Hill middle range. Tennessee clay and fragipan layers add some excavation time over national averages, but the labor rate is lower here than in coastal markets, which roughly balances.
How much does a French drain cost per linear foot?
Exterior French drains in Spring Hill cost $30 to $55 per linear foot. Interior crawlspace and basement French drains cost $50 to $95 per linear foot. The exterior range covers a 24 to 36 inch deep trench with 4 inch perforated PVC pipe, gravel envelope, geotextile fabric wrap, and surface restoration. Interior rates are higher because the work happens in tight spaces, demolition and reset of concrete slab edges is involved, and a sump pit and pump are usually part of the system.
What makes one French drain project cost more than another?
Five main cost drivers: total linear feet, trench depth, outlet routing distance, surface restoration scope, and whether a sump pit is part of the system. A 40 foot single-side drain with a daylight outlet 10 feet away and a strip of sod restoration is the cheap end. A 180 foot full perimeter drain with a 120 foot solid pipe outlet run, hardscape demolition, and a sump pit with battery backup is the expensive end.
Is a French drain worth the investment in Spring Hill?
On a property with a chronic drainage problem, yes. Untreated drainage problems compound: hydrostatic pressure cycles damage foundation walls, persistent wet soil accelerates differential foundation movement, and saturated yards lose grass and gain mosquitoes year after year. A $4,500 French drain typically prevents far more expensive downstream repairs and protects resale value. On a property with no current drainage issue, a French drain is preventive but not always cost-justified.
Are there cheaper alternatives to a French drain?
Sometimes. Simple corrective grading to slope water away from the house, downspout extensions, and surface catch basins can solve mild drainage problems for $800 to $2,500. These work when the problem is purely surface water from inadequate grading or downspout placement. They do not work when the problem is fragipan-trapped subsurface water, which is most chronic Spring Hill drainage issues. The on-site walk tells us which category the property is in.
Do you offer financing for French drain projects?
We don't carry in-house financing. Most homeowners pay by credit card, check, or bank transfer. Some homeowners use a HELOC or a home improvement loan from their bank or credit union, which is sometimes worth the interest cost for an emergency drainage repair on a property with active foundation damage.
