Price Ranges by Scope
Run lengths are multiplied out from HomeBlue's Dallas French drain data. Where the water can legally go sets the length, so the French drain outlet options for your lot type come first; the build itself is covered on French drain installation in Prosper.

What Affects Cost in Prosper TX
Linear Footage
The most direct cost driver. More footage means more trench, more aggregate, more pipe, and more labor. In Prosper, a typical side-yard drain run is 40 to 80 feet. Whole-yard systems that tie the front, sides, and back together can reach 150 to 250 feet.
Trench Depth and Soil
Shallow drains at 12 to 18 inches cost less to install than deep perimeter systems at 24 to 36 inches. Prosper clay is dense and requires more equipment effort than sandy soils. Hand-digging around buried utilities adds labor cost per linear foot in affected sections.
Outlet Type and Distance
The cheapest outlet is a surface discharge at the curb or a low point at the rear of the property. Running pipe to a city storm drain or through a long side yard to reach the street adds both material and labor cost. Some Prosper lots have outlets that are simple; others require routing 80+ feet just to reach a compliant discharge point.
Catch Basins and Cleanouts
A catch basin is a box-style inlet that collects surface water at a specific low point; cleanouts provide access to flush the pipe later. Both add cost, quoted per site, but serve important functions. Most Prosper jobs benefit from at least one catch basin in the low corner of the backyard.
New-Construction vs. Established Yard
Installing drainage in a new-construction Prosper home before landscaping is cheaper than retrofitting a mature yard with sod, irrigation, and established plantings. If you are about to landscape a new home, drainage is much more cost-effective to do first.
Why Prosper Costs Slightly More Than National Averages
National cost sites quote wide ranges: LawnStarter puts exterior French drains at $10 to $65 per linear foot, with a $5,000 average job. Dallas-area pricing is tighter at $23 to $36 per linear foot (HomeBlue). Where a Prosper job lands inside that band comes down to three local factors.
First, the clay. Vertisol clay is significantly harder to trench than sandy or loam soils, and it takes more aggregate volume per linear foot to create a functional drainage bed. Second, outlet complexity: many Prosper lots, especially in newer subdivisions, have limited outlet options because the street curb is at a higher elevation than you would expect, or because the rear of the lot backs to a common area with no permitted discharge point. Third, tight lots: Prosper subdivision lots often require precision work in narrow side yards with fencing, utilities, and irrigation to work around.
None of these factors should deter you from getting a drain installed. The cost is still significantly lower than even minor foundation repair, and a well-installed drain in Collin County clay lasts 20 to 30 years with minimal maintenance.
The Wider DFW Market Rate, For Comparison
It is worth knowing what the rest of the metroplex charges, because it tells you whether a quote you are holding is reasonable. Across the Dallas-Fort Worth market in 2026, installed french drain work runs roughly $23 to $36 per linear foot, and a whole project in North Dallas typically lands between $2,500 and $4,250. A 100 foot run installed generally comes in at $3,000 to $5,000.
Two numbers get quoted that are not comparable and cause a lot of confusion. A surface-only drain, essentially a shallow gravel trench with no engineered outlet, is quoted at $10 to $15 per linear foot. It is cheap because it is not the same product, and on Houston Black clay it silts closed quickly. At the other end, interior or below-slab drainage runs $50 to $60 per linear foot, because it involves working under a structure. If one bid is dramatically under the others, check which of these three things it is actually describing before assuming you found a bargain.
Prosper sits at the upper half of the residential band rather than outside it. The reason is almost always outlet distance rather than any premium on the work itself.
Two Prosper Yards, Same Puddle, Very Different Price
The most common question is why a neighbour paid so much less. Here is the honest arithmetic on the two most common Prosper scenarios.
A standard subdivision lot. The wet corner is at the back fence, the curb is 50 feet away down the side yard, and there is a clean route past the AC pad. That is roughly 50 feet of trench, one catch basin, and a curb outlet. At the Dallas-area rate the trench itself is about $1,150 to $1,800, with the basin and outlet on top, and it is usually a one-day job. Nothing about it is complicated.
An estate lot in Star Trail, Whitley Place, or a rear section of Windsong Ranch. Same puddle, same basin, but the nearest legal outlet is 160 feet away, the route crosses an irrigation zone and a mature bed, and part of it has to be bored under a walkway. Now it is 160 feet of trench and pipe, about $3,680 to $5,760 at the same per-foot rate before the sprinkler rerouting, boring and hand work through the planted section are added. The same visible problem costs several times more.
The puddle is identical. The distance to somewhere the water can legally go is not. This is why a Prosper drainage job should not be quoted from a photo, and why any per-foot price given before someone has established where your outlet is should be treated as a guess.
