How much does french drain installation cost in North Texas?
Most french drain and swale projects here run between $1,500 and $8,000. What moves the number is the length of the run, how deep the trench has to go, whether equipment can reach the work or it has to be hand-dug near the house, the discharge solution at the outlet, and how much surface has to be restored afterward. We set the price after walking the property and seeing where the water is headed, not off a phone call we would only be guessing at.
Do I need a french drain or a surface drain?
If the ground stays soggy and holds water underfoot, that is subsurface water, and a french drain is the right call. If water sheets across the surface and ponds, a surface drain, a channel drain, or a regraded swale usually clears it for less money. We diagnose which one you have before we quote either.
Where does the water actually discharge?
To a legal, sensible outlet at a lower grade than everything feeding it, because a drain is only as good as the place it lets go. In practice that means daylighting the line where the ground falls away, tying into the street or curb where the city allows it, or running to a dedicated drainage easement. What we never do is aim water at a neighbor's lot or across a property line, which is both a bad-neighbor move and, in most North Texas jurisdictions, against the drainage rules. We settle the outlet on paper before the first trench is cut, because designing a drain from the discharge point backward is the difference between a system that empties itself and a pipe that just relocates the puddle. On a tight lot with no obvious low corner, finding that outlet is half the job, and sometimes the honest answer is a sump and a pump rather than gravity.
Why does my yard pool up after heavy rain?
Usually flat or inverted grade, compacted clay that refuses to absorb, roof water dumping faster than the yard can shed it, or all three at once. The fix might be regrading, drainage, or both together, and the walkthrough is what tells us which.
Will a french drain keep water off my foundation?
A drain placed correctly intercepts water before it can sit against the slab, and on expansive clay it is that steady moisture cycle at the perimeter that keeps a foundation moving. We pair drains with surface grading so the grade itself is the first thing moving water away, and the pipe is the backup.
How long does an installation take?
Most residential french drain and regrade systems are measured in days, not weeks. A single straight run in reachable ground can go in and get dressed back in a day or two; a lot that needs several lines, deep trenching near the foundation, or a good deal of surface put back together runs longer. What stretches a schedule is hand-digging where a machine cannot fit, hitting rock or old utilities, and the amount of sod, beds, and hardscape we have to restore at the end. You get a realistic window up front, not a vague soon, and a call the day anything shifts, because wet-season weather is the one variable we will not pretend away: saturated ground will not trench or backfill clean, so a storm week can push a start. We would rather move a day than churn your yard into mud that has to be redone.
