French Drain Cost in Fort Worth: What Affects the Price
The cost of a French drain in Fort Worth depends mostly on how long it is, how deep it goes, what's in the way, and where the water will be sent. A short run across open lawn costs far less than a long drain that wraps around the house, crosses under a walkway and ties into the gutters.
We don't publish set prices, because every drainage job is different and material and fuel costs keep changing. This guide explains what drives the price, how French drains compare with other drainage options, and what professional French drain installation should include.
What a French Drain Is (and Isn't)
A French drain is a sloped trench lined with filter fabric, filled with gravel and fitted with perforated pipe. Water in soaked soil seeps into the gravel, enters the pipe and flows by gravity to a safe outlet, such as the street, a lower part of the property or a pop-up emitter.
It's the right tool for water that soaks into the ground and won't leave: soggy low areas, wet soil along a foundation, or groundwater seeping down a slope. It isn't the best tool for every problem:
Water sheeting off a driveway or patio is usually better handled by a channel drain.
A flat yard with nowhere lower to send water may need a pump drain.
Water pouring from downspouts often just needs underground downspout lines, which can tie into a French drain if one is going in.
Factors That Affect French Drain Cost
Length. Many contractors price French drains by the linear foot, so a longer run costs more.
Depth and soil. Deeper trenches and hard, rocky or heavy clay soil take longer to dig.
Access. Tight side yards, fences, mature trees, beds and concrete slow the work or add steps.
The outlet. Sending water to the curb, to a lower part of the lot or to a pop-up emitter changes how much pipe and trenching the job needs.
Materials. Pipe type, fabric quality and the amount of gravel all affect the price.
Add-ons. Downspout tie-ins, catch basins and cleanouts add cost but often make the system work better.
Restoration. Replacing sod, replanting beds and cleaning up after trenching.
Whether you're in Weatherford, Aledo or Fort Worth, a good quote spells out each of these items so you can compare bids fairly.
French Drain vs. Other Drainage Options
Option | Best for | What moves the cost |
French drain | Soaked soil, low areas, wet ground along a foundation | Length of the run, depth and the outlet |
Channel drain | Water running off driveways, patios and pool decks | Length, and cutting into existing concrete |
Pump drain | Flat or low yards with no natural slope to an outlet | Pump and basin size, and getting power to the pump |
Underground downspout lines | Moving roof water away from the foundation | Number of downspouts and distance to the outlet |
Low spots and ground that slopes toward the house | Area covered and how much soil is moved or brought in |
Many yards need a combination, such as downspout lines tied into a French drain. The only reliable number is an on-site quote: estimates are free, and there's never a trip charge.
Is a French Drain Worth It?
A French drain is usually worth it when:
The same areas stay soggy for days after every heavy rain.
Water collects along your foundation.
Wet soil is killing grass, trees or beds.
Erosion keeps washing soil and mulch away.
In North Texas clay, water that sits against a slab can lead to foundation movement, and foundation repair typically costs far more than drainage work. Fixing the water early protects the bigger investment.
It may not be worth it when the problem is surface water from paving (a channel drain is cheaper and works better), or when extending a downspout or regrading a small low spot solves it. If you're not sure what you're dealing with, start with the signs of a yard drainage problem, and rule out your sprinklers with our soggy yard test.
What Professional Installation Includes
Site assessment. Where the water comes from, where it can go, and how much fall the ground allows.
Utility locates. Buried lines are marked through Texas811, the state's call-before-you-dig system, before any trenching starts.
Trenching with the right slope. The trench must fall steadily toward the outlet, or water will sit in the pipe.
Fabric, gravel and perforated pipe. Fabric keeps soil from clogging the gravel; the pipe carries the water away.
A proper outlet. A curb outlet, pop-up emitter or another safe discharge point.
Backfill and cleanup. Trenches filled, and sod or beds restored.
Testing. Running water through the system to confirm it drains.
Before you sign, ask who handles restoration, how the outlet will cope with heavy storms, and what warranty covers the work.
Frequently Asked Questions
How long does a French drain last?
A well-built French drain with filter fabric and clean gravel can last for decades. The main cause of failure is silt clogging the gravel or pipe, which proper fabric and cleanouts help prevent.
Can a French drain be installed next to my foundation?
Yes. Drains along the foundation are common, but the depth, distance from the slab and outlet need careful planning so the drain carries water away without disturbing the soil that supports the slab.
Does a French drain need maintenance?
Very little. Keep the outlet clear of debris and mulch, and flush the line through a cleanout if water starts draining slowly. Downspout tie-ins need an occasional check for leaves.
French drain or regrading: which do I need?
Regrading fixes ground that slopes the wrong way or has shallow low spots. A French drain handles water that soaks into the soil and stays there. Many yards need both, which a drainage assessment will show.
Why don't you list French drain prices online?
Every drainage job is different, and material and fuel costs keep changing, so a published price would rarely match your yard. A free on-site estimate gives you an accurate number, and there's never a trip charge.
