Key takeaways
- A typical Dallas-area range for a standard exterior French drain is about $25 to $55 per foot installed.
- The outlet decides more of the price than the footage: a short run to a pop-up costs far less than a deep run to the curb.
- Restoration (sod, sprinkler lines, cut concrete) is real money; make sure an estimate includes it.
- Local wages for this work run below the national average, which is part of why DFW ranges sit where they do.
A standard exterior French drain in the Irving and Dallas area typically costs about $25 to $55 per foot installed, which puts a 60-foot side-yard run at roughly $1,500 to $3,300 before any curb core, pump or concrete work. That range covers a trench, filter fabric, washed stone, perforated pipe and a basic outlet. Rein Irving Drainage Company publishes the range so you can check an estimate against it; a site visit turns it into a written number for your yard.
What moves a French drain toward the high end
Of all these, the outlet matters most. A drain that can empty at a pop-up emitter twenty feet away is a small job. The same drain on a flat lot where the nearest allowed outlet is the street curb a hundred feet away is a much larger one, and a lot with no lower outlet at all needs a pump. Our guide to where a French drain can drain lays out the options.
What is inside an Irving French drain price
Some parts of the price have public figures behind them; others depend entirely on your yard.
A wage is not a billing rate. The hourly rate a contractor charges also carries insurance, licensing, vehicles, equipment and overhead, so it is always well above the wage figures. The wage gap is one reason Dallas-area prices do not simply track national averages.

Ways to keep the cost down
- Fix roof water first. If downspouts dump at the wet area, burying them in solid pipe can shrink or remove the need for a French drain.
- Check whether the problem is surface water. A puddle on clay may need a catch basin or regrading instead. Our French drain versus catch basin guide explains how to tell.
- Share one outlet. Several lines that end at the same curb core or swale cost less than separate outlets.
- Phase a large job. A whole-yard plan can be built in stages if each stage ties into the same outlet.
What a fair estimate should list
A useful French drain estimate names the trench length and depth, the pipe and fabric, where the outlet is and what kind, any permit or curb-core work, and exactly what restoration is included. If an estimate is a single per-foot price with none of that, ask what happens at the outlet and who repairs the sprinklers. For the wider picture across every kind of drainage work, see drainage cost in Irving, or try the cost tool for your own length. To have the range turned into a written number, call for an estimate or use the form.
Questions people ask
Is a French drain priced per foot or per job?
Most estimates are built from the length of trench, but the total also includes the outlet, any curb core or pump, and restoration. Comparing two quotes by their per-foot number alone can hide what each one leaves out.
Why do some quotes come in far below $25 a foot?
Very low figures usually mean a shallow trench with sock pipe and no filter fabric, little or no restoration, or no real outlet. Those drains tend to clog quickly in Irving clay.
Does a curb outlet cost extra?
Usually, because it adds a longer run, a cut through the curb and, where the city requires it, a permit. Coppell's 2022 permit for a residential curb core for yard drains carried a $100 fee.
