Low / Mid / High Project Scenarios
Low Scenario
$1,690$56 per linear foot
Short yard drain at standard depth with no sump pump or landscape repair.
Mid Scenario
$5,807$73 per linear foot
Exterior perimeter drain at standard depth with moderate landscape repair.
High Scenario
$30,181$151 per linear foot
Long interior perimeter drain at deep excavation with battery backup sump and full landscape restore.
What Changes the Estimate Most in Los Angeles?
- Drain length and trench depth create the widest price spread between a short surface drain and a full perimeter system.
- Soil type, utility crossings, and landscape restoration are the main reasons french-drain labor varies significantly between sites.
- Sump-pump tie-ins, channel drains, and waterproof membrane additions are the extras that most often expand a french-drain estimate.
When This Calculator Is Less Accurate
This calculator is less accurate when the project includes interior perimeter systems, sump-pump integration, heavy clay excavation, or landscape restoration beyond a standard exterior french-drain installation.
Use the result as a budgeting starting point, then validate with local contractor quotes if the scope includes specialty materials, hidden damage, or permit-driven design changes.
How Much Does French Drain Installation Cost in Los Angeles?
French drains and perimeter drainage systems often total roughly $2,000–15,000 depending on how many linear feet you treat, whether the pipe runs inside or outside the foundation, how deep crews must dig, and whether you add a sump and landscape restoration.
Cost Factors:
- Interior perimeter systems usually cost more per foot than yard drains because of concrete cutting, dust control, and discharge routing
- Depth and soil type (clay, rock, or high water table) drive machine vs hand digging time and shoring needs
- Discharge daylighting, dry wells, or tie-ins to storm sewers change pipe sizing, cleanouts, and permitting
- Sump pumps become necessary when gravity outlets are not lower than the slab or crawl floor you are protecting
- Restoring sod, mulch beds, or hardscape after trenching is easy to underestimate on long exterior runs
In Los Angeles, home improvement costs are 19% above the national average. This reflects local labor rates, material availability, and cost of living in the Los Angeles metro area.
Frequently Asked Questions (5)
How localized is the French Drain Installation estimate for Los Angeles, CA?
This page applies a West regional cost model plus local signals for Los Angeles, CA, so totals are modeled around 19% above a national baseline before you change inputs. Use it as a budgeting range, then compare written quotes for your exact scope.
What should I verify with contractors in Los Angeles?
Confirm permits, HOA or historic-district rules, material lead times, and whether demolition or hidden damage is included. California codes and local inspection steps can change both price and schedule compared with national averages.
What is a French drain used for?
It collects groundwater or surface runoff in a perforated pipe buried in gravel, then routes water away from foundations, yards, or basements. It is a common fix for soggy lawns and hydrostatic pressure against basement walls.
Interior vs exterior French drain—which costs more?
Interior perimeter drains typically carry higher per-foot pricing because of slab work, debris handling, and finished-space protection. Exterior systems can be cheaper per foot but may require more landscaping repair.
Will I need a sump pump with a French drain?
Only if there is no gravity outlet lower than the area being drained. Crawl spaces and basements often need a sump and pump to lift water to daylight or a storm connection.
