Clogged, crushed or silted-up drains
Tallahassee Yard Drainage French Drain Repair and Cleaning in Tallahassee
A French drain that used to work and now does nothing has usually failed in one of four ways. Finding which one decides whether it is a cleaning or a dig.

Tallahassee Yard Drainage sets up French drain repair for Tallahassee homeowners whose drain has stopped doing its job, whether it was installed last year or came with the house. Before anyone digs, the drain should be diagnosed, because a clogged pipe that can be jetted clean and a drain that was built wrong look exactly the same from the lawn.
Jetting and a camera run usually cost $250 to $650; skipping that step and trenching the whole run on a guess costs $4,000 or more, and still misses the problem if the real fault was a crushed outlet at the far end.
$250 to $650 to diagnose and clean, $1,200 to $4,000 to rebuild a section
A camera inspection and hydro-jetting of a French drain in Tallahassee typically runs $250 to $650. Excavating and rebuilding a failed section, with new fabric, stone and pipe, typically runs $1,200 to $4,000 depending on length and depth. Replacing an entire drain is priced like a new installation.
Get a price: (850) 604-5871Signs a French drain has failed
- The ground over the drain is soggy, but the outlet stays dry during rain
- Water bubbles up out of the trench line or a cleanout cap
- The pop-up emitter at the end never opens, or is buried under grass
- A sinkhole or a sunken strip has appeared along the drain route
- Tree roots are visible at the outlet, or the yard has a large oak near the line
- The drain worked for a year or two and then gradually stopped
The four ways French drains fail here
Silt through missing fabric
The most common failure in Tallahassee. The clay-enriched subsoil is full of very fine particles, and a trench that was never wrapped in filter fabric slowly fills its gravel and pipe with red mud. Jetting can clear the pipe, but the stone around it stays clogged, so a silted drain usually needs the affected section rebuilt properly.
A blocked or buried outlet
Grass grows over a pop-up emitter, a mower crushes it, or someone lays sod across the daylight end of the pipe. The whole drain backs up because the last two feet failed. This is the cheap one, and it is why the outlet is the first thing a good contractor checks.
Roots
Live oaks and water oaks send roots toward the only damp, oxygenated line in a dry yard. Perforated pipe near a big tree is an invitation. A cutting head on a jetter removes them; rerouting or switching to solid pipe near the tree stops them coming back.
Wrong fall from day one
A pipe laid flat, or with a belly where it sags, holds water instead of moving it. A camera shows the standing water in the line. The only fix is to reset that section to a steady fall.
Diagnosis before digging
The sensible order is: find the outlet and confirm it is open, run a hose into the high end or the cleanout and watch what happens, then push a camera through the line to see where the water stops. That sequence turns a guess into a known fault at a known distance, and it means the repair trench is ten feet long instead of a hundred.
If there is no cleanout, adding one at the high end during the repair is worth the small cost. It makes the next cleaning a one-hour job.

Call (850) 604-5871When repair turns into replacement
If the camera shows silt along most of the run, or the drain was built without fabric in clay from end to end, patching sections will not save it. At that point a new French drain installation, built correctly, is the better use of the money. The old trench often gives a head start on the route.
Sometimes the honest answer is that a French drain was the wrong fix. A drain installed to solve a surface-water problem that a regrade or a swale would have handled will keep disappointing, however well it is repaired.
Keeping a repaired drain working
- Keep the pop-up emitter visible and clear of grass and mulch
- Do not let downspouts dump roof water and leaves straight into a French drain without a filter
- Have the line jetted every few years if it runs near large trees
- Watch the outlet during the first heavy rain after the repair
Drain backing up toward the house?
A failed drain that pushes water back toward a foundation is worth diagnosing this week, not next season. Call and describe where the water shows up.

How much does French drain repair cost in Tallahassee?
A camera inspection and jetting typically runs $250 to $650. Rebuilding a failed section runs about $1,200 to $4,000 depending on length and depth.
Why is my French drain not draining?
Usually a blocked or buried outlet, silt from a trench built without filter fabric, tree roots, or a pipe laid without a steady fall. A hose test and a camera show which.
Can a clogged French drain be cleaned?
The pipe can be jetted clean, and roots can be cut out. If silt has filled the gravel around the pipe, that section has to be dug up and rebuilt with fabric.
What are the signs my French drain is failing?
Soggy ground over the drain while the outlet stays dry, water bubbling from the trench line, a buried or crushed pop-up emitter, sunken strips along the route, and a gradual decline over a year or two.
Should I repair or replace my French drain?
Repair when the fault is local: an outlet, a root intrusion or one bad section. Replace when the whole run is silted or was built without fabric in clay.
Often done together
-
French drain installation
A gravel trench and perforated pipe that pulls water out of the ground and carries it somewhere it is allowed to go.
-
Pop-up emitters
The green cap in the lawn that lets a buried pipe release water. When it fails, everything upstream of it fails too.
-
Clay soil drainage
Red loam on top, clay-rich subsoil underneath. Water gets through the first and stops at the second. Fixing a soggy Red Hills yard starts with knowing that.
Talk it through before anyone digs
Describe where the water sits and where it comes from. You will hear which fix fits the yard, what it usually costs, and whether you need one at all.
