French Drain Installation
French Drain Installation in Las Cruces, NM
Water pooling against your foundation, a side yard that turns to mud every monsoon, or a block wall that holds water like a dam? A French drain collects that water underground and carries it somewhere it can’t do damage.

Quick answer
How much does a French drain cost in Las Cruces?
An outdoor French drain usually costs $10 to $35 per linear foot installed. Most yard drains run 30 to 100 feet, so a typical job lands between $1,000 and $3,500, and national totals range from about $500 to $8,800. Deeper drains along a foundation run $30 to $90 per foot.
Price depends on length, depth, how hard the digging is (caliche adds time), and where the water goes: daylighting to a lower spot is cheapest, while a dry well or a pop-up emitter adds cost. You get a written, itemized price before we start.
What’s in a French drain we install
When you need one
Problems a French drain fixes
Las Cruces only gets about 9 to 10 inches of rain a year, but much of it falls in short, heavy monsoon storms from July to September. On flat lots, tight soil and caliche, that water has nowhere to go.
Water against the foundation
Puddles along the slab or stucco after storms or irrigation, which can lead to cracking, efflorescence and settling.
Side yards between block walls
Narrow side yards where water runs down from the backyard and sits against the house or wall.
Downspout and canale runoff
Roof water dumping in one spot, eroding rock beds or pooling at the patio.
Soggy lawn areas
Low spots that stay wet for days, kill grass and grow weeds and mosquitoes.
Water perched on caliche
Water that soaks a few inches and then sits on the hard layer instead of draining away.
Slopes above patios or walls
Uphill yards that send water across a patio or behind a retaining wall.

Options
French drain, swale, dry creek or regrade?
A French drain isn’t always the answer. In the desert, fixing the surface slope often does more than burying pipe. We look at where the water comes from before recommending anything.

How it works
Our French drain installation process
You see the route, the outlet and the price before any digging starts.
1
Watch the water
We look at where water comes from, where it pools and where it can safely go.
2
Route and price
A marked route, trench depth and outlet, with a written, itemized estimate.
3
Locate and dig
Utilities marked through New Mexico 811, then the trench is dug to a steady fall.
4
Fabric, pipe and rock
Filter fabric, perforated pipe on a gravel bed, then washed drain rock over the top.
5
Test and finish
We run water through the line, check the outlet, and restore the rock or landscaping on top.
Done right
What separates a French drain that works from one that fails
|
Detail |
Why it matters |
|---|---|
|
Continuous downhill slope |
Water only moves if the whole line falls toward the outlet |
|
Filter fabric around the rock |
Keeps fine desert soil and sand out of the gravel |
|
Washed, clean drain rock |
Leaves open space for water to flow into the pipe |
|
Perforations facing down |
Water rises into the pipe from below instead of sitting |
|
A real outlet |
A drain that ends in the ground just moves the puddle |
|
Cleanout access |
Lets you flush out silt after heavy monsoon storms |
Where the water can go
If you want water sent to the street or into a public drainage area, check with the City of Las Cruces or your HOA first.
Local know-how
French drains in Las Cruces soil
Caliche
A hard layer a foot or two down can stop water cold. We break through it where needed, or pair the drain with a dry well that reaches looser ground.
Monsoon cloudbursts
Storms can drop a lot of rain in minutes. We size pipe and outlets for fast water, not just a slow drizzle.
Blowing sand
Wind-blown sand clogs open gravel. Fabric wrap and a rock or DG cap keep the drain clean for years.
Block walls
Many subdivisions have block walls with small drain openings. We keep those clear and route water through them only where the layout was designed for it.
Stucco and slab homes
Water sitting against stucco and slab edges causes staining and cracking. We keep water and irrigation spray away from the walls.
Irrigation water too
Much of the pooling we see comes from sprinklers, not rain. We check the irrigation before blaming the grade.
