A French drain that used to work and now doesn't is usually clogged, crushed or cut off from its outlet. Here is how contractors find the problem, when cleaning is enough, and when replacing the run makes more sense.

Why French drains fail in Tulsa
| Cause | What happens | Typical remedy |
|---|---|---|
| Silt and clogged fabric | Fine silt from Tulsa's silt loam and clay soils works into the gravel and pipe | Jetting can clear the pipe; clogged gravel and fabric usually mean digging up that section |
| Tree roots | Roots find the moisture and grow into perforations and joints | Mechanical cutting or jetting, then rerouting or replacing the section if roots keep coming back |
| Crushed or separated pipe | Vehicles, equipment or shifting soil crush the pipe or pull joints apart | Excavate and replace the damaged section |
| Lost slope | A low belly in the pipe holds water and sediment | Re-lay that section at the right fall |
| Buried or blocked outlet | Landscaping, mulch or a fence buried the outlet, or the pop-up is stuck | Clear or rebuild the outlet |
| No real outlet | The drain was built to end in a gravel pit with nowhere to go | Redesign with an outlet; may mean a new run |
Older Tulsa homes, half of them built in 1973 or earlier, may have buried drains and downspout lines decades old. Some older systems use materials and fabric socks that are harder to clean, though what's in your yard is only known once someone looks.
How contractors diagnose and fix a failing drain
Find the ends
The contractor locates the outlet and any cleanouts. If there are none, they may need to dig to find the pipe.
Flow test
Running a hose into the high end shows whether water reaches the outlet, and how fast.
Camera inspection
A small camera pushed through the pipe shows roots, silt, breaks or bellies, and a locator can mark where they are on the surface.
Clean or jet
A water jetter or drain cable clears silt and roots from the pipe when the problem is inside it.
Repair or replace
Damaged sections get dug up and replaced. If the trench is clogged end to end, rebuilding it may cost less than repeated repairs.
Repair, clean or replace?
| Finding | Usually means |
|---|---|
| Pipe clogged but the gravel and fabric are clean | Cleaning or jetting, plus adding a cleanout |
| One crushed section or a root intrusion | Spot repair of that section |
| Outlet buried or stuck | Outlet repair, often the cheapest fix |
| Gravel and fabric clogged along the run | Replacing the drain |
| No working outlet or wrong slope throughout | A redesigned drain |
Repair work is often priced per visit or per section, and a camera inspection may be a separate line. Replacement is priced like a new drain: published Tulsa figures run $23–$36 per linear foot (HomeBlue, May 2024), and Fixr's national typical project is $2,800–$6,500 (Jan 2025). Add sod at $1–$2 per square foot (Bob Vila, Jun 2024). These are published estimates, not quotes. See French drain installation and the cost guide.
Before anyone digs
Oklahoma law requires anyone digging for hire to contact OKIE811 at least 48 hours ahead (excluding weekends and holidays). It's free. Sprinkler lines and other private lines aren't marked, so your contractor should plan for them.
Inside Tulsa city limits, the city's Watershed Development Permit rules cover excavating, grading and regrading, and work in the street right-of-way (like running a pipe through the curb) needs a separate right-of-way permit. Ask your contractor whether your project needs a permit, or call City of Tulsa Development Services (311). Suburbs have their own rules.
Tulsa's Residential Site Plan Guidebook says properties must convey drainage "without causing damage to adjoining properties," and water can't be blocked from flowing onto your lot from uphill. A good plan carries water to the street or another approved outlet, never onto a neighbor and never into a sanitary sewer.
If a repaired drain still can't keep up, the issue may be upstream: roof water from downspouts overloading it, or grading that sends more water than one drain can carry.
Questions to ask
- What exactly did the camera or flow test show? Can I see the video?
- Is this a cleaning job, a spot repair or a replacement, and why?
- Will you add cleanouts so this is easier next time?
- What caused the failure, and how will the repair avoid it?
- Is lawn restoration included?
- Can I see proof of liability insurance?
Oklahoma doesn't issue a state license for general, landscape or drainage contractors. Plumbing, electrical and mechanical work does require a Construction Industries Board license. Ask any contractor for proof of liability insurance, and use a licensed plumber for anything tied into your home's plumbing.
Signed at the kitchen table?
If you sign at home, the FTC Cooling-Off Rule generally gives you three business days to cancel, and Oklahoma law gives a similar right for financed home-solicitation sales. A fair quote will still be good after you sleep on it.
French Drain Repair FAQ
Can a clogged French drain be cleaned?
Often the pipe can. A water jetter or drain cable pushed through a cleanout or the outlet can clear silt and roots from inside the pipe. If the gravel and fabric around it are packed with silt, cleaning the pipe won't restore much flow and that section usually has to be dug up and rebuilt.
How long does a French drain last?
There's no fixed lifespan. A well-built drain with good fabric, clean gravel, steady slope, a working outlet and a cleanout can last many years, especially if it's flushed now and then. Drains built without fabric, with no outlet or under heavy tree roots tend to fail much sooner.
What does a camera inspection show?
A small waterproof camera on a cable is pushed through the pipe and records what it sees: roots, silt, crushed spots, separated joints and low bellies where water sits. Many systems include a locator so the contractor can mark the problem's spot on the lawn. Ask to see the footage.
Should I repair or replace my French drain?
Repair makes sense when the problem is in one spot: a crushed section, a root intrusion or a buried outlet. Replacement makes sense when the gravel and fabric are clogged along the whole run, the slope is wrong throughout, or there was never a proper outlet. A camera inspection helps you decide.
