Water pooling against a foundation sends most homeowners searching for a drainage contractor in Downers Grove, IL, and that search term is a fair description of the problem. It is not always a fair description of the fix, because the answer is usually a grade correction rather than a pipe.
With over 25 years of experience, the team at Green Grass Landscape has spent a long time reading how water moves across yards in this part of DuPage County. What we build is landscape construction, and grade is one of the first things it settles.
We're a design and build company rather than a pipe-only outfit, so where water goes gets decided while the patio, the walk and the beds are being laid out, which is usually a better moment to fix it than after.
Most wet spots in DuPage County yards are not plumbing failures. They are low points. Clay-heavy soil holds water where the ground stops falling, and a yard that was rough-graded once at construction has had fifteen years of settling, mulch top-ups and bed edges added since.
That is why we start with elevations rather than with a product. Reading the fall across a yard tells you where water wants to go, and the fix is often to give it that route rather than to intercept it.
Every hard surface changes the way a yard sheds water. A patio, a paver driveway or a walk removes an absorbing surface and replaces it with one that moves water somewhere else. Where that somewhere is has to be a design decision, not a discovery.
On our builds the slope of the paving, the height of the bed edges and the finished lawn grade are drawn together. Getting them right at that stage costs a conversation. Getting them wrong costs a rebuild.
Downspouts belong at the front of that conversation. A single downspout can put a remarkable volume of roof water at one corner of a foundation, and no amount of yard grading downstream will out-argue that.
Where the roof water is released, and how far out from the house, changes what the rest of the plan needs to do.
Plant selection is part of the answer, not decoration on top of it. Beds that sit at the low end of a yard take a different plant palette than beds on the high side, and a bed built up above the surrounding grade behaves differently again.
Our maintenance crews see the consequences of getting this wrong on other people's installations regularly. Shrubs planted in a low spot rarely fail dramatically. They sulk for three years and then get replaced, which is why choosing material that tolerates a wet foot is cheaper than replanting the same bed twice.
Two things, and neither requires a measurement. Note where the water sits and how long it takes to leave after a heavy rain, because a puddle that clears in an hour is a different problem from one that lasts two days.
Then note what you want the space to do, since the answer changes if a patio is going in. Photographs taken during the rain are more useful than a description afterward, and a short video of where water is moving is better still.
If a low spot has been bothering you for a couple of seasons, the useful next step is a walk-through while the ground still shows where water went this summer. A wet corner is often solved inside a project you already wanted.

How long after a heavy rain should a Downers Grove yard stay wet?
A yard that drains reasonably will clear surface water within a few hours. Standing water a day or two later usually points to a low point or a compaction layer rather than to soil type alone.
Can grading work be done at the same time as a patio project?
Combining the two is generally the better sequence. Green Grass Landscape draws the paving slope, bed heights and lawn grade as one plan, so the water route is built rather than retrofitted.
Is autumn a reasonable time to correct a wet area?
Fall is a practical window in Illinois. The ground still shows where water traveled over the summer, and turf repairs made in early fall establish before the ground freezes.
