Homeowners typically pay for a full perimeter French drain installation based on trench length, material quality, and labor. The price range reflects yard slope, soil type, and whether landscaping or hardscape work is required. This article covers the cost to install a French drain around a house, with realistic low, average, and high estimates and per-unit details.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Perimeter trenching (linear ft) | $6 | $12 | $25 | Includes spoil removal |
| Perforated drain pipe (per ft) | $2 | $3.50 | $6 | Corrugated or solid-socket pipe |
| Gravel/drain rock (per ton) | $30 | $45 | $70 | Rolled or crushed stone |
| Filter fabric (per 100 ft) | $10 | $15 | $25 | Geotextile wrap |
| Grading and backfill (per sq ft) | $0.50 | $1.25 | $3 | Soil prep and compaction |
| Sump pump (optional, each) | $100 | $250 | $500 | With check valve |
| Labor (hourly, crew) | $40 | $70 | $125 | Trips, disposal, and setup |
| Permits (regional) | $0 | $100 | $500 | Depends on locality |
Assumptions: Midwest to Southeast regions, standard soil, normal access, and a single continuous trench around the home foundation.
Typical Total Price for a Full Perimeter Drain
For a standard single-story home with a 150–200 linear feet footprint, the installed price typically runs from $4,000 to $10,000, with a common mid-point around $5,500 to $7,500. If soil is rocky, access is tight, or landscaping must be restored, expect higher totals. Perimeter layouts longer than 200 feet or with multiple laterals can push costs into the $10,000–$15,000 range. Assumptions: average soil, typical yard restoration, and one sump pump option not required.
Major Cost Components You’ll See on a Quote
Understanding the breakdown helps compare bids without surprises. The cost components below show where values come from and what can be negotiated. Concrete edging, extensive grading, or decorative lighting typically add costs.
- Materials — pipe, filter fabric, gravel, backfill, and any fittings; ranges per linear foot.
- Labor — installation crew time, trenching, backfill, and cleanup; commonly billed by hour or by project.
- Equipment — trenchers, compactors, and temporary power; may be charged as rental or included in labor.
- Permits — local permit or inspection fees; varies by jurisdiction.
- Delivery/Disposal — rock, fabric, pipe delivery and removal of excavated soil.
- Warranty — typical parts-and-labor warranty; extended plans may add cost.
Key Variables That Change the Final Price
Two primary drivers swing the total: trench length and soil conditions. Longer runs add material and labor linearly, while rocky soil or clay slows digging and requires more backfill.
- Trench length and layout: perimeter length, number of corners, and any interior spurs.
- Soil and drainage grade: hardpan or clay increases excavation effort and backfill volume.
- Material choices: higher-grade pipe, thicker filter fabric, or larger stone raises cost.
- Labor availability: regional rates vary; mountains or remote areas incur travel time.
- Site access: fenced yards, driveways, or landscaping near the foundation may require careful planning.
How to Cut Costs Without Sacrificing Function
Smart scope management can reduce the price while preserving drainage effectiveness. Bundle services, opt for standard perforated pipe, and limit decorative site work to avoid added costs.
- Limit scope to essential drainage versus full yard retrofit.
- Choose standard pipe and geotextile instead of premium options.
- Schedule installation in dry seasons to reduce labor hold times and weather delays.
- Request multiple quotes to compare line-item pricing and avoid upsells.
Regional Price Differences You Might See
Prices can swing by region due to labor costs, permit requirements, and access. Coastal cities tend to be higher than inland markets for the same trench length.
| Region | Typical Range | Notes |
|---|---|---|
| Northeast urban | $6,000–$12,000 | Higher labor and disposal costs |
| Midwest suburban | $4,500–$9,000 | Standard soil, easier access |
| South rural | $3,500–$7,000 | Lower labor; soil varies |
Labor Time and Scheduling Outlook
Expect crews to spend 2–5 days on a typical 150–200 ft perimeter, depending on site conditions. Labor rates commonly range from $40–$125 per hour per crew, with travel time included in some bids. Heavy rain or compacted soils can extend project duration by 1–3 days.
Materials Choices by Budget and Performance
Lower-cost installations use standard perforated PVC or corrugated pipe with basic gravel. Higher-end setups may use dual-wall pipe, larger aggregate, and additional filter fabrics to reduce clogging. For most homes, standard components provide reliable drainage at mid-range prices.
Perimeter Drain vs. Lateral Extensions
Installing a perimeter drain around the house differs from adding interior or exterior laterals. Perimeter systems often require longer trenching and more backfill, increasing both material and labor costs. Perimeter layouts are typically the most cost-effective when addressing foundation drainage broadly.
What a Realistic 3-Quote Scenario Looks Like
Three quotes for a 180 ft perimeter around a single-story home might show ranges such as: Quote A $5,200 (standard materials), Quote B $7,300 (mid-range materials with backfill), Quote C $9,800 (premium pipe, fabric, and full landscaping restoration). Assumptions: Midwest region, average soil, normal yard access.
Notes on Additional Costs to Watch
Unexpected issues can raise totals: trench crossings under sidewalks, irrigation adjustments, or disposal of old materials. Always budget a contingency of 5–15% for surprises.
