French Drain Installation in McKinney, TX
Clay soil and flat yards create standing water problems on McKinney properties. We install French drains and complete drainage systems that route water off your lot permanently.
Drainage Problems in McKinney
McKinney is one of the most established cities in Collin County, and its housing stock spans everything from 1970s ranch homes to brand-new subdivisions in the far north. Drainage problems exist across all of it, because the underlying issue is the soil. Blackland prairie clay runs deep under McKinney, and it does not let water pass quickly.
In older neighborhoods, the problem is often a combination of mature landscaping that has changed the grading around the foundation, plus downspouts that have always drained poorly. In newer subdivisions near the Prosper and Celina borders, the issues look more like what we see in Prosper: builder grading that created low spots between homes, property-line drainage that routes water from uphill neighbors onto your lot, and tight lots with nowhere for the water to go.
The fix is a French drain: a buried aggregate-and-pipe system that intercepts water where it collects and moves it to a safe outlet. We scope each job based on the actual flow paths on your property, not a generic design.
French Drain Services in McKinney
Yard and Surface Drainage
We identify low points and surface flow paths on your property, then design a drain system that collects water at those points and routes it to a curb outlet or rear drain.
Foundation Perimeter Drains
A tight drain around the perimeter of your foundation intercepts water before it can saturate the soil against the slab. Critical for McKinney homes where downspouts discharge close to the house.
Property-Line Intercept Drains
When adjacent lots drain onto yours, an intercept drain at the boundary stops the inflow before it reaches your yard. Common in McKinney subdivisions where shared grading creates predictable conflict points.
Catch Basin and Downspout Routing
Surface catch basins collect water in low spots; underground downspout piping routes roof drainage to a controlled outlet. Both can be combined into a single connected system.
Free Drainage Inspection in McKinney
Before anyone quotes you a drainage installation, somebody has to establish where the water actually comes from. That is what our free McKinney drainage inspection does. It takes about 45 minutes: we walk the whole lot, shoot grades with a level rather than eyeballing the fall, trace every downspout to its discharge point, check the low areas against the property corners, and confirm which legal outlets your lot can reach.
You get the water paths and the outlet plan in writing at the end, whether or not you hire us. The reason we do it this way is that the obvious puddle is very often not the problem. On a majority of McKinney inspections, at least one significant flow path turns out to originate off the property, either an uphill neighbour's grading or a builder swale that was never maintained, and that changes what the right fix is. Quoting a drain without that information produces a system that moves the puddle 15 feet.
The same visit covers existing systems. If you already have drainage that has stopped working, we scope it as a drainage system repair rather than assuming replacement, because in McKinney the fault is frequently a single crushed section or a silted outlet rather than a whole failed run.
Commercial and HOA Drainage in McKinney
We take commercial water drainage work in McKinney alongside residential: small retail and office pads, church properties, and HOA common areas. The usual calls are parking-lot sheet flow crossing a walkway, area inlets that have silted shut, saturated detention pond slopes that cannot be mowed, and landscape drainage on common ground that floods amenity areas after every spring storm.
One local rule shapes almost every commercial job here and is worth knowing before you get quotes. In this part of Collin County, surface runoff crossing a property line from a nonresidential lot requires a dedicated public drainage easement, and a developed nonresidential lot is not permitted to surface drain onto a residential lot. That constraint decides the outlet, and the outlet decides the design and most of the cost. We establish easement and outlet options before quoting, not after, which avoids the common sequence where a cheap bid turns into a change order once someone reads the standards.
For HOA boards, we can provide the system drawing and outlet plan in the format architectural committees and property managers expect for records and for owner communication.
Drainage by McKinney Neighborhood
McKinney is not one drainage market. The city's housing stock runs from 1970s ranch homes through 1990s master-planned golf communities to subdivisions finished last year, and the age of the neighbourhood predicts the failure mode more reliably than anything else.
West McKinney's large master-planned community, with sections built from the late 1980s onward around golf and lake amenities. Two drainage patterns dominate here: mature tree canopy and 30 years of accumulated landscaping have quietly reversed the original grade next to a lot of foundations, and older lots back onto greenbelt and lake margins where the outlet is downhill but a long way off. Long outlet runs are normal on these properties.
Established south McKinney with tree-lined streets and larger mature landscaping. The recurring issue is root intrusion into older drainage runs and downspouts that were adequate when the trees were small. Repair rather than new installation is more common here than anywhere else in the city.
Newer construction in northwest McKinney. The problems match what we see in Prosper's new builds: builder rough grading that satisfies code by draining to the street while sending yard water toward the slab or the rear property line, plus tight side yards between homes where two lots' runoff converges into one channel.
Denser village-style and older central lots where there is simply less yard to work with. Outlet routing is the constraint, and channel drains plus underground downspout routing often do more here than a long French drain would.
New subdivisions along the northern McKinney boundary toward Prosper and Celina. Same blackland clay, same builder grading patterns, and these lots are on our regular northern Collin County route.
We also cover the US-75 and SH-121 corridors and the whole northern McKinney boundary. McKinney is about 15 minutes from our Prosper base and sits on our regular northern Collin County route, so scheduling here is not a travel-surcharge job.
What French Drain Installation Costs in McKinney
Installed French drain work in the DFW market runs roughly $23 to $36 per linear foot, and most McKinney residential jobs land between $1,800 and $6,000 in total. A straightforward side-yard run of 40 to 60 feet with a clear route to the curb sits at the bottom of that band. Full perimeter work, multiple collection points, or a run that has to cross a driveway sits at the top.
What moves the number in McKinney specifically is rarely the drain itself. It is the obstacles: mature root systems in Craig Ranch and older Stonebridge Ranch sections that have to be cut around rather than through, irrigation lines to reroute, long outlet runs to a greenbelt or lake margin, and concrete to core or bore under.
